FIRE SAFETY TIPS
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 elec-
trical 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. It is NOT designed for marine or RV use.
•
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.
All BRK® and 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 pho-
to-electric 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.

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.
In general, install combination Smoke and Carbon Monoxide
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
(12 meters) long, install a unit at each end.
• 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.
Installing Smoke/CO Alarms in Mobile Homes
For minimum security install one Smoke/CO Alarm as close to each
sleeping area as possible. For more security, put one unit in each room.
Many older mobile homes (especially those built before 1978) have little
or no insulation. If your mobile home is not well insulated, or if you are
unsure of the amount of insulation, it is important to install units on
inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, kitchens, 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/CO 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/CO
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.
On a peaked, gabled, or cathedral ceiling, install the 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.

IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO IF CARBON MONOXIDE IS DETECTED
Actuation of your CO Alarm indicates the presence of carbon mon-
oxide (CO) which can kill you. In other words, when your CO Alarm
sounds, you must not ignore it!
WHAT TO DO IF SMOKE IS DETECTED
• 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 battery to quiet an unwanted alarm.
Removing the battery disables the Alarm so it cannot sense
smoke. This will remove 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.
If the unit alarms and you are certain that the source of smoke is not a
fire—cooking smoke or an extremely dusty furnace, for example—open
a nearby window or door and fan the smoke away from the unit. Use
the Silence Feature to silence the Alarm. This will silence the alarm, and
once the smoke clears the unit will reset itself automatically.
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.
IF THE CO ALARM 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 Smoke/CO Alarm remains
in its normal condition.
4. After following steps 1-3, if your Smoke/CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance tech-
nician 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:

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 until you hear an acknowledge chirp.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
SILENCING THE LOW BATTERY WARNING
This Silence Feature can temporarily quiet the low battery warning
“chirp” for up to 8 hours. Press the Test/Silence button on the Alarm
cover until you hear the acknowledge “chirp”.
Once the low battery warning “chirp” silence feature is activated, the unit
continues to flash the green light once a minute for 8 hours. After
8 hours, the low battery “chirp” will resume. Note, if battery is dead,
Low Battery Silence cannot be activated and alarm will continue to chirp
approximately once per minute. 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).
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.
SILENCING THE END OF LIFE SIGNAL
This silence feature can temporarily quiet the End of Life warning “chirp”
for up to 2 days. You can silence the End of Life warning “chirp” by
pressing the Test/Silence button.The horn will chirp, acknowledging that
the End of Life silence feature has been activated.
After approximately 2 days, the End of Life “chirp” will resume.
4. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
5. 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.
6. Line the mounting bracket up over the plastic screw anchors.
7. Screw the mounting bracket to the ceiling or wall through the
mounting slots using the two screws provided.
8.
Position the base of the Smoke/CO Alarm over the mounting bracket
and turn. The Alarm will remain secure over a wide rotation range
to allow for perfect alignment. When wall mounting, this will allow
fine-tuning on the positioning to compensate for out of aligned wall
studs and to keep the wording level. The Alarm can be positioned
over the bracket every 120°. Rotate the Alarm until aligned properly.
9. Test the Smoke/CO Alarm. See “Weekly Testing” for details.
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” or “CO” Red LED will begin to flash On 2
seconds/Off 2 seconds. It will continue to flash or “latch” until you clear
it by testing the alarm.
This feature helps emergency responders, investigators, or service
technicians identify which unit(s) in your home were exposed to alarm
levels of smoke or carbon monoxide. This can help investigators
pinpoint the source of smoke or CO.
The Latching Alarm Indicator stays ON until you clear it, so it can alert
you to an alarm that occurred while you were away from home, even
though smoke or CO present in the air has dropped below alarm levels.
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. 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.
Latching Features Note: Low Battery Latch or Alarm Latch are only
engaged for about 15 minutes to conserve power. Low Battery
Latch and Alarm Latch do not operate with a missing battery.
• This unit will not alert hearing impaired residents. It is
recommended that you install special units which use devices
like flashing strobe lights to alert hearing impaired residents.
• 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.
• The battery compartment resists closing unless a battery is
installed. This warns you the unit will not operate without a
battery.
• Do not stand too close to the unit when the alarm is sounding.
It is loud to wake you in an emergency. Exposure to the horn
at close range may harm your hearing.
• Do not paint over the unit. Paint may clog the openings to the
sensing chambers and prevent the unit from operating properly.

between battery changes. 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”).
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.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: por table 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 exchang-
er, 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 intend-
ed 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.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
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.
However, they do not provide interconnected functionality.
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 Interconnected Alarms: Offer the same interconnected
functionality as with hardwired alarms, without wires. Units are easy
to install and do not require professional installation. They provide
protection even when electricity fails, provided the batteries are fresh
and correctly installed.
Smoke Alarms for Solar or Wind Energy users and battery backup
power systems: AC powered Smoke Alarms should only be operated
with true or pure sine wave inverters. Operating this Smoke 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. These units 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 NFPA (National Fire Protection Association) 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 com-
mon 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 build-
ings, 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 ware-
houses, 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, especial-
ly 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.

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 appli-
ances 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 caus-
es 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.
This Smoke/CO Alarm is not foolproof. Like all other electronic devic-
es, 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.
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.
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 bed-
room. 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.
