INTRODUCTION
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 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.

SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposur : Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Mdium Exposur : Throbbing headache, drowsiness, confusion, fast heart rate.
Extr m Exposur : 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 b obligat d
to pay for any carbon monoxid inv stigation or s rvic call.
POTENTIAL SOURCES OF CO IN THE HOME
Fu l-burning applianc s lik :
portable heater, gas or wood
burning fireplace, gas kitchen
range or cooktop, gas clothes dryer.
Damag d or insuffici nt v nting:
corroded or disconnected water
heater vent pipe, leaking chimney pipe
or flue, or cracked heat exchanger,
blocked or clogged chimney opening.
Improp r us of applianc /d vic :
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transi nt CO Probl ms: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
Th following conditions can r sult in transi nt 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 substitut for prop r maint nanc of hom applianc s.
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, familiariz yours lf with all nclos d mat rials. R ad this
manual in its ntir ty, and mak sur you und rstand 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 R quir d 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 D t ction at Typical T mp ratur and Humidity Rang s: 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.
Audibl Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smok Alarms in Singl -Family R sid nc s
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 recom-
mended 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.
Mor sp cifically, install Smok 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 require-
ments in your area. It is r comm nd d AC or AC/DC units b int rconn ct d
for add d prot ction. C ntinued...
ABOUT SMOKE ALARMS, C ntinued
Smok Alarms for th h aring impair d: 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.
Smok alarms ar not to b us d with d t ctor 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 Smoke Alarm to install, refer to
National Fire Protection Association (NFPA) Standard 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.
F atur s:
• Separate sensors to detect smoke
and CO; the two alarm systems
work independently
• Voice with programmable location
• Separate audible and visual
signals to indicate alarm levels
of smoke or CO
• Powered by two “AA” batteries
•Side access drawer for easy
battery replacement
All First Al rt®Smok Alarms conform to r gulatory r quir m nts,
including UL217 and ar d sign d to d t ct particl s of combustion.
Smok particl s of varying numb r and siz ar produc d in all fir s.
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 prot ction, us both typ s of Smok Alarms on ach
l v l and in v ry b droom of your hom .
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, condo-
miniums, 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).
Smok /CO Alarms may not wak n all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to grand-
parents. 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.
Smok /CO Alarms cannot work without pow r. 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 Smok /CO Alarm will not s ns smok or CO that do s not r ach th
snsors. 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 Smok /CO Alarm may not s ns smok or CO on anoth r l v l of th
hom . 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.
Smok /CO Alarms may not b h ard. 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 condi-
tioner, 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.
Th Alarm may not hav tim to alarm b for th fir its lf caus s damag ,
injury, or d ath, sinc smok from som fir s may not r ach th unit imm di-
at ly. Exampl s of this includ p rsons smoking in b d, childr n playing with
match s, or fir s caus d by viol nt xplosions r sulting from scaping gas.
This Smok /CO Alarm is not a substitut for lif insuranc . 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 Smok /CO Alarm has a limit d lif . 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 Smok /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.

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 g n ral, install combination Smok and Carbon Monoxid 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).
Rcomm nd d Plac m nt
•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 Sm ke/CO Alarms in M bile H mes
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 locat this Smok /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”.

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.
Th s fu ls includ : Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, 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. C ntinued...

INTRODUCTION
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 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.

COMBINATION CARBON MONOXIDE & SMOKE ALARM
WITH VOICE & LOCATION

SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposur : Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Mdium Exposur : Throbbing headache, drowsiness, confusion, fast heart rate.
Extr m Exposur : 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 b obligat d
to pay for any carbon monoxid inv stigation or s rvic call.
POTENTIAL SOURCES OF CO IN THE HOME
Fu l-burning applianc s lik :
portable heater, gas or wood
burning fireplace, gas kitchen
range or cooktop, gas clothes dryer.
Damag d or insuffici nt v nting:
corroded or disconnected water
heater vent pipe, leaking chimney pipe
or flue, or cracked heat exchanger,
blocked or clogged chimney opening.
Improp r us of applianc /d vic :
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transi nt CO Probl ms: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
Th following conditions can r sult in transi nt 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 substitut for prop r maint nanc of hom applianc s.
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, familiariz yours lf with all nclos d mat rials. R ad this
manual in its ntir ty, and mak sur you und rstand 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 R quir d 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 D t ction at Typical T mp ratur and Humidity Rang s: 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.
Audibl Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smok Alarms in Singl -Family R sid nc s
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 recom-
mended 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.
Mor sp cifically, install Smok 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 require-
ments in your area. It is r comm nd d AC or AC/DC units b int rconn ct d
for add d prot ction. C ntinued...
ABOUT SMOKE ALARMS, C ntinued
Smok Alarms for th h aring impair d: 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.
Smok alarms ar not to b us d with d t ctor 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 Smoke Alarm to install, refer to
National Fire Protection Association (NFPA) Standard 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.
F atur s:
• Separate sensors to detect smoke
and CO; the two alarm systems
work independently
• Voice with programmable location
• Separate audible and visual
signals to indicate alarm levels
of smoke or CO
• Powered by two “AA” batteries
•Side access drawer for easy

Smok particl s of varying numb r and siz ar produc d in all fir s.
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.

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, condo-
miniums, 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).
Smok /CO Alarms may not wak n all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to grand-
parents. 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.
Smok /CO Alarms cannot work without pow r. 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 Smok /CO Alarm will not s ns smok or CO that do s not r ach th
snsors. 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 Smok /CO Alarm may not s ns smok or CO on anoth r l v l of th
hom . 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.
Smok /CO Alarms may not b h ard. 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 condi-
tioner, 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.
Th Alarm may not hav tim to alarm b for th fir its lf caus s damag ,
injury, or d ath, sinc smok from som fir s may not r ach th unit imm di-
at ly. Exampl s of this includ p rsons smoking in b d, childr n playing with
match s, or fir s caus d by viol nt xplosions r sulting from scaping gas.
This Smok /CO Alarm is not a substitut for lif insuranc . 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 Smok /CO Alarm has a limit d lif . 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 Smok /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.

WHERE TO INSTALL THIS ALARM
Minimum cov rag for Smok 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 g n ral, install combination Smok and Carbon Monoxid 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).
Rcomm nd d Plac m nt
•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 Sm ke/CO Alarms in M bile H mes
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 locat this Smok /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”.
HOW TO INSTALL THIS ALARM

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 c ilings, 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 p ak d, gabl d, or cath dral c iling, 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.

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.
Th s fu ls includ : Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, 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. C ntinued...

INTRODUCTION
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 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.

SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposur : Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Mdium Exposur : Throbbing headache, drowsiness, confusion, fast heart rate.
Extr m Exposur : 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 b obligat d
to pay for any carbon monoxid inv stigation or s rvic call.
POTENTIAL SOURCES OF CO IN THE HOME
Fu l-burning applianc s lik :
portable heater, gas or wood
burning fireplace, gas kitchen
range or cooktop, gas clothes dryer.
Damag d or insuffici nt v nting:
corroded or disconnected water
heater vent pipe, leaking chimney pipe
or flue, or cracked heat exchanger,
blocked or clogged chimney opening.
Improp r us of applianc /d vic :
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transi nt CO Probl ms: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
Th following conditions can r sult in transi nt 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 substitut for prop r maint nanc of hom applianc s.
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, familiariz yours lf with all nclos d mat rials. R ad this
manual in its ntir ty, and mak sur you und rstand 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 R quir d 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 D t ction at Typical T mp ratur and Humidity Rang s: 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.
Audibl Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smok Alarms in Singl -Family R sid nc s
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 recom-
mended 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.
Mor sp cifically, install Smok 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 require-
ments in your area. It is r comm nd d AC or AC/DC units b int rconn ct d
for add d prot ction. C ntinued...
ABOUT SMOKE ALARMS, C ntinued
Smok Alarms for th h aring impair d: Special purpose Smoke Alarms should

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.

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, condo-
miniums, 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).
Smok /CO Alarms may not wak n all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to grand-
parents. 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.
Smok /CO Alarms cannot work without pow r. 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 Smok /CO Alarm will not s ns smok or CO that do s not r ach th
snsors. 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 Smok /CO Alarm may not s ns smok or CO on anoth r l v l of th
hom . 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.
Smok /CO Alarms may not b h ard. 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 condi-
tioner, 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.
Th Alarm may not hav tim to alarm b for th fir its lf caus s damag ,
injury, or d ath, sinc smok from som fir s may not r ach th unit imm di-
at ly. Exampl s of this includ p rsons smoking in b d, childr n playing with
match s, or fir s caus d by viol nt xplosions r sulting from scaping gas.
This Smok /CO Alarm is not a substitut for lif insuranc . 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 Smok /CO Alarm has a limit d lif . 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 Smok /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.

ABOUT SMOKE ALARMS
Batt ry (DC) op rat d Smok 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 pow r d Smok Alarms: Can be interconnected so if one unit senses
smoke, all units alarm. They do not operate if electricity fails.
AC with batt ry (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.
Smok /CO Alarms for Solar or Wind En rgy us rs and batt ry backup
pow r syst ms: AC powered Smoke/CO Alarms should only be operated

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum cov rag for Smok 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 g n ral, install combination Smok and Carbon Monoxid 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).
Rcomm nd d Plac m nt
•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 Sm ke/CO Alarms in M bile H mes
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 locat this Smok /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 c ilings, 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 p ak d, gabl d, or cath dral c iling, 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.

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.
Th s fu ls includ : Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, 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. C ntinued...

INTRODUCTION
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 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.

SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposur : Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Mdium Exposur : Throbbing headache, drowsiness, confusion, fast heart rate.
Extr m Exposur : 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 b obligat d
to pay for any carbon monoxid inv stigation or s rvic call.
POTENTIAL SOURCES OF CO IN THE HOME
Fu l-burning applianc s lik :
portable heater, gas or wood
burning fireplace, gas kitchen
range or cooktop, gas clothes dryer.
Damag d or insuffici nt v nting:
corroded or disconnected water
heater vent pipe, leaking chimney pipe
or flue, or cracked heat exchanger,
blocked or clogged chimney opening.
Improp r us of applianc /d vic :
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transi nt CO Probl ms: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
Th following conditions can r sult in transi nt 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 substitut for prop r maint nanc of hom applianc s.
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, familiariz yours lf with all nclos d mat rials. R ad this
manual in its ntir ty, and mak sur you und rstand 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 R quir d 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 D t ction at Typical T mp ratur and Humidity Rang s: 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.
Audibl Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smok Alarms in Singl -Family R sid nc s
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 recom-
mended 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.
Mor sp cifically, install Smok 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 require-
ments in your area. It is r comm nd d AC or AC/DC units b int rconn ct d
for add d prot ction. C ntinued...
ABOUT SMOKE ALARMS, C ntinued
Smok Alarms for th h aring impair d: 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.
Smok alarms ar not to b us d with d t ctor 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 Smoke Alarm to install, refer to
National Fire Protection Association (NFPA) Standard 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.
F atur s:
• Separate sensors to detect smoke
and CO; the two alarm systems
work independently
• Voice with programmable location
• Separate audible and visual
signals to indicate alarm levels
of smoke or CO
• Powered by two “AA” batteries
•Side access drawer for easy

All First Al rt®Smok Alarms conform to r gulatory r quir m nts,
including UL217 and ar d sign d to d t ct particl s of combustion.
Smok particl s of varying numb r and siz ar produc d in all fir s.
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.

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, condo-
miniums, 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.

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).
Smok /CO Alarms may not wak n all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to grand-
parents. 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.
Smok /CO Alarms cannot work without pow r. 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 Smok /CO Alarm will not s ns smok or CO that do s not r ach th
snsors. 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 Smok /CO Alarm may not s ns smok or CO on anoth r l v l of th
hom . 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.
Smok /CO Alarms may not b h ard. 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 condi-
tioner, 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.
Th Alarm may not hav tim to alarm b for th fir its lf caus s damag ,
injury, or d ath, sinc smok from som fir s may not r ach th unit imm di-
at ly. Exampl s of this includ p rsons smoking in b d, childr n playing with
match s, or fir s caus d by viol nt xplosions r sulting from scaping gas.
This Smok /CO Alarm is not a substitut for lif insuranc . 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 Smok /CO Alarm has a limit d lif . 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 Smok /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.

ABOUT SMOKE ALARMS
Batt ry (DC) op rat d Smok 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 pow r d Smok Alarms: Can be interconnected so if one unit senses
smoke, all units alarm. They do not operate if electricity fails.
AC with batt ry (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.
Smok /CO Alarms for Solar or Wind En rgy us rs and batt ry backup
pow r syst ms: 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 damag th Alarm. If you are not sure about
your inverter or UPS type, please consult with the manufacturer to verify.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum cov rag for Smok 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 g n ral, install combination Smok and Carbon Monoxid 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).
Rcomm nd d Plac m nt
•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 Sm ke/CO Alarms in M bile H mes
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 locat this Smok /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 c ilings, 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 p ak d, gabl d, or cath dral c iling, 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.

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.
Th s fu ls includ : Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, 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. C ntinued...

INTRODUCTION
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 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.

SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposur : Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Mdium Exposur : Throbbing headache, drowsiness, confusion, fast heart rate.
Extr m Exposur : 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 b obligat d
to pay for any carbon monoxid inv stigation or s rvic call.
POTENTIAL SOURCES OF CO IN THE HOME
Fu l-burning applianc s lik :
portable heater, gas or wood
burning fireplace, gas kitchen
range or cooktop, gas clothes dryer.
Damag d or insuffici nt v nting:
corroded or disconnected water
heater vent pipe, leaking chimney pipe
or flue, or cracked heat exchanger,
blocked or clogged chimney opening.
Improp r us of applianc /d vic :
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transi nt CO Probl ms: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
Th following conditions can r sult in transi nt 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 substitut for prop r maint nanc of hom applianc s.
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, familiariz yours lf with all nclos d mat rials. R ad this
manual in its ntir ty, and mak sur you und rstand 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 R quir d 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 D t ction at Typical T mp ratur and Humidity Rang s: 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.
Audibl Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smok Alarms in Singl -Family R sid nc s
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 recom-
mended 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.
Mor sp cifically, install Smok 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 require-
ments in your area. It is r comm nd d AC or AC/DC units b int rconn ct d
for add d prot ction. C ntinued...
ABOUT SMOKE ALARMS, C ntinued
Smok Alarms for th h aring impair d: 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.
Smok alarms ar not to b us d with d t ctor 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 Smoke Alarm to install, refer to
National Fire Protection Association (NFPA) Standard 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.
F atur s:
• Separate sensors to detect smoke
and CO; the two alarm systems
work independently
• Voice with programmable location
• Separate audible and visual
signals to indicate alarm levels
of smoke or CO
• Powered by two “AA” batteries
•Side access drawer for easy
battery replacement
All First Al rt®Smok Alarms conform to r gulatory r quir m nts,
including UL217 and ar d sign d to d t ct particl s of combustion.
Smok particl s of varying numb r and siz ar produc d in all fir s.
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 prot ction, us both typ s of Smok Alarms on ach

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, condo-
miniums, 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).
Smok /CO Alarms may not wak n all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to grand-
parents. 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.
Smok /CO Alarms cannot work without pow r. 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 Smok /CO Alarm will not s ns smok or CO that do s not r ach th
snsors. 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 Smok /CO Alarm may not s ns smok or CO on anoth r l v l of th
hom . 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.
Smok /CO Alarms may not b h ard. 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 condi-
tioner, 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.
Th Alarm may not hav tim to alarm b for th fir its lf caus s damag ,
injury, or d ath, sinc smok from som fir s may not r ach th unit imm di-
at ly. Exampl s of this includ p rsons smoking in b d, childr n playing with
match s, or fir s caus d by viol nt xplosions r sulting from scaping gas.
This Smok /CO Alarm is not a substitut for lif insuranc . 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 Smok /CO Alarm has a limit d lif . 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 Smok /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.

INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum cov rag for Smok 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 g n ral, install combination Smok and Carbon Monoxid 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).
Rcomm nd d Plac m nt
•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 Sm ke/CO Alarms in M bile H mes
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 locat this Smok /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”.
HOW TO INSTALL THIS ALARM

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.
Th s fu ls includ : Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, 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. C ntinued...

INTRODUCTION
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 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.

SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposur : Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Mdium Exposur : Throbbing headache, drowsiness, confusion, fast heart rate.
Extr m Exposur : 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 b obligat d
to pay for any carbon monoxid inv stigation or s rvic call.
POTENTIAL SOURCES OF CO IN THE HOME
Fu l-burning applianc s lik :

Damag d or insuffici nt v nting:
corroded or disconnected water

or flue, or cracked heat exchanger,
blocked or clogged chimney opening.
Improp r us of applianc /d vic :
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transi nt CO Probl ms: “transient” or on-again-off-again CO problems can
be caused by outdoor conditions and other special circumstances.
Th following conditions can r sult in transi nt 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 substitut for prop r maint nanc of hom applianc s.
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, familiariz yours lf with all nclos d mat rials. R ad this
manual in its ntir ty, and mak sur you und rstand 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 R quir d 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 D t ction at Typical T mp ratur and Humidity Rang s: 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.
Audibl Alarm: 85 dB minimum at 10 feet (3 meters).
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smok Alarms in Singl -Family R sid nc s
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 recom-
mended 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.
Mor sp cifically, install Smok 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 require-
ments in your area. It is r comm nd d AC or AC/DC units b int rconn ct d
for add d prot ction. C ntinued...
ABOUT SMOKE ALARMS, C ntinued
Smok Alarms for th h aring impair d: 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.
Smok alarms ar not to b us d with d t ctor 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 Smoke Alarm to install, refer to
National Fire Protection Association (NFPA) Standard 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.
F atur s:
• Separate sensors to detect smoke
and CO; the two alarm systems
work independently
• Voice with programmable location
• Separate audible and visual
signals to indicate alarm levels
of smoke or CO
• Powered by two “AA” batteries
•Side access drawer for easy

Smok particl s of varying numb r and siz ar produc d in all fir s.
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.

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, condo-
miniums, 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).
Smok /CO Alarms may not wak n all individuals. Practice the escape plan
at least twice a year, making sure that everyone is involved – from kids to grand-
parents. 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.
Smok /CO Alarms cannot work without pow r. 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 Smok /CO Alarm will not s ns smok or CO that do s not r ach th
snsors. 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 Smok /CO Alarm may not s ns smok or CO on anoth r l v l of th
hom . 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.
Smok /CO Alarms may not b h ard. 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 condi-
tioner, 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.
Th Alarm may not hav tim to alarm b for th fir its lf caus s damag ,
injury, or d ath, sinc smok from som fir s may not r ach th unit imm di-
at ly. Exampl s of this includ p rsons smoking in b d, childr n playing with
match s, or fir s caus d by viol nt xplosions r sulting from scaping gas.
This Smok /CO Alarm is not a substitut for lif insuranc . 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 Smok /CO Alarm has a limit d lif . 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 Smok /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.

WHERE TO INSTALL THIS ALARM
Minimum cov rag for Smok 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 g n ral, install combination Smok and Carbon Monoxid 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).
Rcomm nd d Plac m nt
•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 Sm ke/CO Alarms in M bile H mes
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 locat this Smok /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 c ilings, 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 p ak d, gabl d, or cath dral c iling, 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.

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.
Th s fu ls includ : Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, 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. C ntinued...
