INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

mounting slot is aligned in the 12 o’clock position and trace around
the inside of the mounting slots (vertical and horizontal mounting).
2. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
3. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
4. Insert the plastic screw anchors (in the plastic bag with screws) into
the holes. Tap the screw anchors gently with a hammer, if necessary,
until they are flush with the ceiling or wall.
5. Line the mounting bracket up over the plastic screw anchors.
6. Screw the mounting bracket to the ceiling or wall through the
mounting slots using the two screws provided.
7. Attach the Smoke/CO Alarm to the mounting bracket. Line up the

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting

hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.

cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.
This user’s manual contains important information about your
Combination Carbon Monoxide & Smoke Alarm’s operation. If you are
installing this Alarm for use by others, you must leave this manual—or
a copy of it—with the end user.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

mounting slot is aligned in the 12 o’clock position and trace around
the inside of the mounting slots (vertical and horizontal mounting).
2. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
3. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
4. Insert the plastic screw anchors (in the plastic bag with screws) into
the holes. Tap the screw anchors gently with a hammer, if necessary,
until they are flush with the ceiling or wall.
5. Line the mounting bracket up over the plastic screw anchors.
6. Screw the mounting bracket to the ceiling or wall through the
mounting slots using the two screws provided.
7. Attach the Smoke/CO Alarm to the mounting bracket. Line up the

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting

2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).
Alarm Will Say:
“Welcome, First Alert Smoke and
Carbon Monoxide Alarm.”
“No location programmed” if
first time or “[Location, example:
“Basement”] location programmed”
when changing batteries.
“To select location, press and
hold test button now.”
2. Press & Hold Test Button if
you would like to program the
location or change the location
of the Alarm. Release button

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

materials properly. Never smoke in bed. 2) Keep matches or lighters
away from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload
electrical circuits; 5) Keep stoves, barbecue grills, fireplaces and
chimneys grease- and debris-free; 6) Never leave anything cooking on
the stove unattended; 7) Keep portable heaters and open flames, like
candles, away from flammable materials;8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately
if they are not working properly. Smoke Alarms that do not work cannot
alert you to a fire. Keep at least one working fire extinguisher on every
floor, and an additional one in the kitchen. Have fire escape ladders or
other reliable means of escape from an upper floor in case stairs are
blocked.
BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences.
• This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.
• This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm
Sounds” for more information on how to respond to an alarm.
Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will
not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after
any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO
levels in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them more
sensitive to carbon monoxide may consider using warning

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

device on the ceiling or wall as outlined below. Read “Where To Install
This Alarm” before starting.
Tools you will need: pencil, drill
with 3/16” or 5mm drill bit,
Phillips screwdriver, hammer.
• Do not install this unit over an electrical junction box. Air
currents around junction boxes can prevent smoke from
reaching the sensing chamber and prevent the unit from
alarming. Only AC powered units are intended for installation
over junction boxes.
If you want to lock the battery compartment, or lock the Smoke/CO
Alarm to the mounting bracket, please read the “Optional Locking
Features” section in the “Quick and Easy Guide to Programming
Your WIRELESS INTERCONNECT Alarm and Using the Optional
Features” attachment before you begin installation.
1. Hold the mounting bracket against the ceiling (or wall) so the vertical
mounting slot is aligned in the 12 o’clock position and trace around
the inside of the mounting slots (vertical and horizontal mounting).
2. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
3. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
4. Insert the plastic screw anchors (in the plastic bag with screws) into
the holes. Tap the screw anchors gently with a hammer, if necessary,
until they are flush with the ceiling or wall.
5. Line the mounting bracket up over the plastic screw anchors.
6. Screw the mounting bracket to the ceiling or wall through the
mounting slots using the two screws provided.
7. Attach the Smoke/CO Alarm to the mounting bracket. Line up the
guides on the alarm’s base with the guides

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).
Alarm Will Say:
“Welcome, First Alert Smoke and

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences.
• This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.
• This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm
Sounds” for more information on how to respond to an alarm.
Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will
not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after
any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO
levels in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them more

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).
Alarm Will Say:
“Welcome, First Alert Smoke and
Carbon Monoxide Alarm.”

by installing the three-wire connector on the ceiling to the Alarm.
6. Repeat steps 1-5 for additional WIRELESS INTERCONNECT
Alarms.
You have now successfully linked your new WIRELESS
INTERCONNECT Alarms.
To add additional Alarms at a later time, follow steps 1 through 5.
ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

Follow safety rules and prevent hazardous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters
away from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload
electrical circuits; 5) Keep stoves, barbecue grills, fireplaces and
chimneys grease- and debris-free; 6) Never leave anything cooking on
the stove unattended; 7) Keep portable heaters and open flames, like
candles, away from flammable materials;8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately
if they are not working properly. Smoke Alarms that do not work cannot
alert you to a fire. Keep at least one working fire extinguisher on every
floor, and an additional one in the kitchen. Have fire escape ladders or
other reliable means of escape from an upper floor in case stairs are
blocked.
BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences.
• This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.
• This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm
Sounds” for more information on how to respond to an alarm.
Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will
not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after
any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO
levels in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them more
sensitive to carbon monoxide may consider using warning

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).
Alarm Will Say:
“Welcome, First Alert Smoke and
Carbon Monoxide Alarm.”
“No location programmed” if
first time or “[Location, example:
“Basement”] location programmed”
when changing batteries.
“To select location, press and
hold test button now.”
2. Press & Hold Test Button if
you would like to program the
location or change the location
of the Alarm. Release button

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences.
• This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.
• This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm
Sounds” for more information on how to respond to an alarm.
Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will
not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after
any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO
levels in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them more

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).
Alarm Will Say:
“Welcome, First Alert Smoke and
Carbon Monoxide Alarm.”
“No location programmed” if
first time or “[Location, example:
“Basement”] location programmed”
when changing batteries.
“To select location, press and
hold test button now.”
2. Press & Hold Test Button if
you would like to program the
location or change the location
of the Alarm. Release button
after Alarm responds.
“To save location, press and

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES
TO LOCK THE MOUNTING BRACKET
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. Insert the locking pin through the
hole on the back of the Alarm as
shown in the diagram.
3. When you attach the Alarm to the
mounting bracket, the locking pin’s
head will fit into a notch on the
bracket.
The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET
1. Insert a flathead screwdriver
into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:
____________________________________________________________
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF
ALARM SIGNAL
Refer to previous section “What You Will See and Hear With This
Alarm”.
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and
your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM
FOR FIRST TIME AND WHEN CHANGING BATTERIES
Action:
1. Insert batteries (2, AA batteries).

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the

for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent

IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the

your CO Alarm remains in its normal condition, you can check what
the highest carbon monoxide level sensed was:
Action:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
now.”
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
If you would like to keep the
highest level in memory, do not
press anything.
“Highest carbon monoxide level
cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.
STEP BY STEP GUIDE TO PROGRAMMING
THIS ALARM

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences.
• This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate the
presence of smoke that reaches the sensor. The Smoke Alarm
is not designed to sense gas, heat or flames.
• This Smoke/CO Alarm cannot operate without working
batteries. Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life, removes
your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm
Sounds” for more information on how to respond to an alarm.
Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will
not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after
any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO
levels in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them more

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on

the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:

cleared.”
Alarm will say nothing.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms, the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE: For added protection, install an additional Smoke/CO Alarm at least
15 feet (4.6 meters) away from the furnace or fuel burning heat source
where possible. In smaller homes or in manufactured homes where this
distance cannot be maintained, install the Alarm as far away as possible
from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the
frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and
storage areas, where temperatures normally remain between 40˚ F
and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the Alarm as close to the center
as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE: For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.

WIRELESS OPERATION
First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective
way to provide your family with whole-home safety. All WIRELESS
INTERCONNECT Alarms communicate with each other without wires
or connectors. When one Alarm sounds, they all sound. This provides
your family with an earlier warning of potential danger, and gives you
more time to react.
The communication distance (range) between any two WIRELESS
INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a
home. Some features of a home, such as the number of floors, number/
size of rooms, furniture and types of building materials used may
reduce the range of the Alarms. Examples include: suspended ceilings,
ductwork, large metallic appliances (refrigerators) and metal studs. A
feature of WIRELESS INTERCONNECT Alarms is that they operate as
a mesh network. All Alarms will repeat any alarm signal that is received
to all other WIRELESS INTERCONNECT Alarms. Interference from
structural conditions can be overcome by adding additional Alarms to
route the wireless signal around obstructions.
• The range and proper operation of any wireless device will
vary depending on its surroundings. It is very important that
each Alarm is tested individually before and after installation
to make sure that all Alarms respond properly.
• The WIRELESS INTERCONNECT Alarms are not to be used
outdoors or to transmit between buildings. The Alarms will
not communicate properly under these conditions.
• Metal objects and metallic wallpaper may interfere with
signals from wireless Alarms. Alarms should be tested after
changes to your home such as remodeling, moving furniture,
and with metal doors opened and closed.
Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will
automatically communicate both potential fires and carbon monoxide
presence with all other First Alert®WIRELESS INTERCONNECTSmoke/
CO Alarms.
Changes or modifications not expressly approved by BRK Brands,
Inc. could void the user’s authority to operate the equipment.

All First Alert
®
Smoke Alarms conform to regulatory requirements,
including UL217 and are designed to detect particles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for
hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.
TO LOCK THE BATTERY COMPARTMENT
Do not lock the battery compartment until you install the
batteries and test the Alarm.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install new batteries
and test again. If the Alarm still does
not alarm, replace it immediately.
1. Using needle-nose pliers, detach
one locking pin from the mounting
bracket.
2. After batteries are inserted, then
push the locking pin through the
hole near the battery door latch on
the back of the Alarm.
OPTIONAL LOCKING FEATURES

The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks
in single-family households where unauthorized battery or Alarm removal is not a concern.
These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the
Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking
features you use, remove one or both pins from the mounting bracket using needle-nose pliers.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
TO UNLOCK THE BATTERY COMPARTMENT
1. Remove the Alarm from the
mounting bracket. If the unit is
locked to the bracket, see the
section “To Unlock the Mounting
Bracket.”
2. Insert a flathead screwdriver under
the head of the locking pin, and
gently pry it out of the battery
compartment lock. (If you plan to
relock the battery compartment,
save the locking pin.)
3. To relock the battery compartment,
close the battery door and reinsert
locking pin in lock.
4. Reattach the Alarm to the mounting
bracket.
When replacing the batteries, always
test the Alarm before relocking the battery compartment.
TO UNLOCK THE MOUNTING BRACKET

into the rectangular cut-out on
the mounting bracket nearest to
the locking pin.
2. Pry the Alarm away from the bracket by
pushing up on the screwdriver and
turning the Alarm counterclockwise (left) at
the same time.
IF THE CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent
to the residence. Write down the number of a qualified appliance
technician here:

IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never remove the batteries to quiet an unwanted alarm. Removing
the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. You can silence this Smoke/CO Alarm by pressing the Test/
Silence button on the alarm cover for at least 3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm
is Silenced
When the CO Alarm
is Silenced
The Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.

ADDING AND LINKING ADDITIONAL WIRELESS
INTERCONNECT ALARMS
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is
placed directly next to a fuel-burning source. Ventilate these areas
as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the sensing
chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings, install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
•
NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm:
85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
•
NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du
racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.
WIRELESS INTERCONNECT
ENABLED ALARMS
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when
electricity fails, provided the batteries are fresh and correctly installed.
Units are easy to install, and do not require professional installation.
AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to

SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS

10 12
REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
•
NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.

WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are more energy efficient.
“Air-tight” homes with added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO. BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning
fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water
heater vent pipe, leaking chimney pipe or flue, or cracked heat
exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or
vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO
problems can be caused by outdoor conditions and other special
circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposure times as
described below. They are measured in parts per million (ppm) of CO
over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN 60 and 240 MINUTES.
*Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This CO
Alarm monitors the air at the Alarm, and is designed to alarm before CO
levels become life threatening. This allows you precious time to leave
the house and correct the problem. This is only possible if Alarms are
located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The
CO Alarm is not formulated to detect CO levels below 30 ppm typically.
UL tested for false alarm resistance to Methane (500 ppm), Butane (300
ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol
(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one
Smoke Alarm on every floor, in every sleeping area, and in every
bedroom. In new construction, the Smoke Alarms must be AC powered
and interconnected. See “Agency Placement Recommendations” for
details. For additional coverage, it is recommended that you install a
Smoke Alarm in all rooms, halls, storage areas, finished attics, and
basements, where temperatures normally remain between 40˚ F (4.4˚
C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
long (12 meters), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom of
the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to
state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/
DC units be interconnected for added protection.

AC powered Smoke Alarms: Can be interconnected so if one unit
senses smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided
the batteries are fresh and correctly installed. AC and AC/DC units must
be installed by a qualified electrician.
WIRELESS INTERCONNECT Smoke Alarms with battery (DC) back-
up: Interconnects with all WIRELESS INTERCONNECT
enabled Smoke
and Smoke/CO Alarms without wires or connectors, so when one alarm
sounds, they all sound. Will operate if electricity fails, provided the
batteries are fresh and correctly installed. Units are easy to install, and
do not require professional installation.
Smoke/CO Alarms for Solar or Wind Energy users and battery
backup power systems: AC powered Smoke/CO Alarms should only
be operated with true or pure sine wave inverters. Operating this Alarm
with most battery-powered UPS (uninterruptible power supply) products
or square wave or “quasi sine wave” inverters will damage the Alarm.
If you are not sure about your inverter or UPS type, please consult with
the manufacturer to verify.
Smoke Alarms for the hearing impaired: Special purpose Smoke
Alarms should be installed for the hearing impaired. They include a
visual alarm and an audible alarm horn, and meet the requirements of
the Americans With Disabilities Act. Can be interconnected so if one
unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.
All these Smoke Alarms are designed to provide early warning of fires
if located, installed and cared for as described in the user’s manual,
and if smoke reaches the Alarm. If you are unsure which type of unit to
install, refer to National Fire Protection Association (NFPA) 72 (National
Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code).
National Fire Protection Association, One Batterymarch Park, Quincy, MA
02269-9101. Local building codes may also require specific units in
new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This Smoke Alarm is suitable for use in apartments, condominiums,
townhouses, hospitals, day care facilities, health care facilities, boarding
houses, group homes and dormitories provided a primary fire detection
system already exists to meet fire detection requirements in common
areas like lobbies, hallways, or porches. Using this Smoke Alarm in
common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
This Smoke Alarm alone is not a suitable substitute for complete fire
detection systems in places housing many people—like apartment
buildings, condominiums, hotels, motels, dormitories, hospitals, health
care facilities, nursing homes, day care facilities, or group homes of any
kind. It is not a suitable substitute for complete fire detection systems
in warehouses, industrial facilities, commercial buildings, and special-
purpose non-residential buildings which require special fire detection
and alarm systems. Depending on the building codes in your area, this
Smoke Alarm may be used to provide additional protection in these
facilities.
In new construction, most building codes require the use of AC or AC/
DC powered Smoke Alarms only. In existing construction, AC, AC/
DC, or DC powered Smoke Alarms can be used as specified by local
building codes. Refer to NFPA 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code), local building codes, or
consult your Fire Department for detailed fire protection requirements in
buildings not defined as “households”.
HUD MAP Program
Certain HUD battery powered Smoke Alarm applications, especially
those that fall under HUD 223(f) MAP (Multi-family Accelerated
Processing), may require a 10 Year sealed tamper resistant battery. This
alarm does not meet that requirement. Substitute First Alert SA340B.

END OF LIFE SIGNAL.
Alarm needs to be replaced.
Immediately replace the Alarm.
This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in
the event of an emergency. It is recommended that you hold a fire drill
while family members are sleeping in order to determine their response
to the sound of the Smoke/CO Alarm while sleeping and to determine
whether they may need assistance in the event of an emergency.
Smoke /CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home. Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used
in conjunction with interconnected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets
or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the Smoke/CO Alarm is installed outside the bedroom, it may not wake
up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed
or only partly open. Even persons who are awake may not hear the alarm
horn if the sound is blocked by distance or closed doors. Noise from
traffic, stereo, radio, television, air conditioner, or other appliances may
also prevent alert persons from hearing the alarm horn. This Smoke/CO
Alarm is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or
the presence of smoke, BRK Brands, Inc. does not warrant or imply in
any way that they will protect lives. Homeowners and renters must still
insure their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 7 years. All Smoke Alarms need to
be replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.

REGULAR MAINTENANCE
This unit has been designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer
or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the Smoke/CO Alarm. Never use water,
cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where
This Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Du
racell MN1500 . These
batteries are available at many local retail stores.
• Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
• Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
IN FIRE. BATTERIES MAY EXPLODE OR LEAK.
• Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
To replace the batteries (without removing Alarm from
the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the
diagram and remove each battery.
3. Insert the new batteries, making sure
they snap completely into the battery
compartment. Match the terminals
on the ends of the batteries with the
terminals on the unit.
4. Close the battery compartment, and
then test the unit by pressing the
Test/Silence button.
AB
WEEKLY TESTING
•
NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing.
When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm by pressing and holding the Test/
Silence button on the Alarm cover until Alarm Voice says “Testing”
(typically 3-5 seconds).
During testing, you will see and hear the following sequence:
• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,
pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Kitchen”]. Evacuate.” The Power/
Smoke LED flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm
Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Kitchen”]. Evacuate.” The Power/Smoke LED will be
Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp”
for up to 8 hours. You can silence the low battery warning “chirp” by
pressing the Test/Silence button on the alarm cover.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the Green light twice a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the batteries as
soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again.
The unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of
smoke or carbon monoxide. After smoke or CO levels drop below alarm
levels, the “Smoke/Power” LED and/or the “CO” Red LED will begin
to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or
“latch” for about 15 minutes, to give you time to determine which unit
initiated the alarm.
Low Battery Latch is activated when the Alarm is in the “low battery
condition”. When this occurs, the Smoke/Power LED flashes Green
On for 2 seconds/Off for 2 seconds for about 15 minutes. This feature
is designed to help you identify which Alarm needs to have the
battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of
“low battery”, the Alarm will chirp in greater intervals than one minute,
sometimes up to several hours, until the battery reaches a steady low
battery level. This innovative feature eliminates the frustration of waiting
for and/or identifying which unit is chirping.
