First Alert PC1210V User manual

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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
level, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper level in case stairs are blocked.

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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
level, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper level in case stairs are blocked.

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

1. Hold the mounting bracket against the ceiling (or wall) so the two clusters of universal mounting holes
are aligned approximately at the 9:00 and 3:00 o’clock positions. See image. Choose one of the three
sets of holes shown, A, B or C (see image) and trace around one of the sets. Be sure to choose a top and
bottom slot on opposite sides so you can rotate the universal mounting bracket into position later. This
will make it easier in the future to remove the mounting bracket without completely removing the screws.
WARNING! Do not install this alarm over an existing electrical box. Only AC
powered units are intended for installation over electrical boxes.
2. Put the unit where it won’t get covered with dust when you drill the mounting holes.
3. Using a 3/16" (5 mm) drill bit, drill a hole through the center of the oval outlines you traced.
4. Insert the plastic screw anchors (in the plastic bag with screws) into the holes. Tap the screw
anchors gently with a hammer, if necessary, until they are flush with the ceiling or wall.
5. Install the screws but do not tighten completely. Attach the mounting bracket by aligning
the screws in the open portion of the universal mounting slots and rotating the bracket into
place. Tighten the screws until they are snug to secure the bracket. Do not over tighten.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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
level, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper level in case stairs are blocked.

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
FIRE SAFETY TIPS

BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important operating instructions or to
potentially hazardous situations. Pay special attention to these items.
• This smoke/CO alarm is approved for use in single-family residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide alarm has two separate alarms. The CO alarm is not designed to detect fire or any other gas.
It will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. The smoke
alarm will only indicate the presence of smoke that reaches the sensor. The smoke alarm is not designed to sense gas, heat or flames.
• This smoke/CO alarm cannot operate without working batteries. Removing the batteries for any reason,
or failing to replace the batteries at the end of their service life, removes your protection.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm Sounds” for more information on how
to respond to an alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem after any alarm. Failure to do so can result in injury or death.
• Test this smoke/CO alarm once a week. If the alarm ever fails to test correctly, have it replaced
immediately! If the alarm is not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

• 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 level stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
RECOMMENDED PLACEMENT:
Smoke Alarm
One on every level and
in every bedroom
Carbon Monoxide Alarm
One on every level and
in every bedroom
Fire Extinguisher
One on every level, plus
kitchen and garage
HALLWAY BEDROOMBEDROOM
GARAGE
LIVING ROOM KITCHEN
BASEMENT
• When installing on the wall, the top edge of smoke alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the center as possible.
• In either case, install at least 4 inches (102 mm) from where the wall and ceiling meet. See “Avoiding Dead Air Spaces” for more information.
NOTE: For any location, make sure no door or other obstruction could keep carbon monoxide or smoke from reaching the alarm.
INSTALLING SMOKE/CO ALARMS IN MOBILE HOMES
For minimum security install one smoke/CO alarm as close to each sleeping area as possible. For more security, put one unit in
each room. Many older mobile homes (especially those built before 1978) have little or no insulation. If your mobile home is not
well insulated, or if you are unsure of the amount of insulation, it is important to install units on inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS SMOKE/CO ALARM:
• In garages, 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 alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,
install the smoke 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 alarms should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
smoke 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.

INTRODUCTION
Thank you for choosing First Alert®for your smoke and carbon monoxide alarm needs. You have purchased a state-of-the-art smoke
& carbon monoxide alarm designed to provide you with early warning of a smoke and/or carbon monoxide danger.
All First Alert®smoke alarms conform to regulatory requirements, including UL217 and are designed to
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at
detecting small particles, which tend to be produced in greater amounts by flaming fires,
which consume combustible materials rapidly and spread quickly. Sources of these fires
may include paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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

• This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure CO levels in compliance with
Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Individuals with medical conditions that may
make them more sensitive to carbon monoxide may consider using warning devices which provide audible and visual signals for carbon
monoxide concentrations under 30 ppm. For additional information on carbon monoxide and your medical condition contact your physician.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on every level, in every
sleeping area, and in every bedroom (See “Regulatory Information for Smoke Alarms” for details on the NFPA recommendations). For CO alarms, the
National Fire Protection Association (NFPA) recommends that a CO alarm should be centrally located outside of each separate sleeping area in the
immediate vicinity of the bedrooms. For added protection, install additional CO alarms in each separate bedroom, and on every level of your home.
NOTE: For added protection, install an additional smoke/CO alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where
possible. In smaller homes or in manufactured homes where this distance cannot be maintained, install the alarm as far away as possible from the furnace or
other fuel burning source. Installing the alarm closer than 15 feet (4.6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
IN GENERAL, INSTALL COMBINATION SMOKE AND CARBON MONOXIDE ALARMS:
• 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 level 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).

which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before
bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.

TESTING & MAINTENANCE
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to
your home. The built-in test switch accurately tests the unit’s operation as required by Underwriters Laboratories,
Inc. (UL). NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be
harmful to your hearing. When testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working properly. Using the
test button is the recommended way to test this smoke/CO alarm.
You can test this smoke/CO alarm by pressing and holding the Test/Silence button on the alarm cover until alarm Voice
says “Testing” (typically 3-5 seconds). During testing, you will see and hear the following sequence:
• The alarm Voice will say “Testing.” The Horn will sound 3 beeps, pause, 3 beeps. The alarm Voice will say “Warning,
evacuate smoke in [Location, example: “Hallway”]. Evacuate.” The Power LED flashes Red.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The alarm Voice will say “Warning, evacuate carbon
monoxide in [Location, example: “Hallway”]. Evacuate.” The LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed, and test again. If the unit still does not alarm, replace it immediately.
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the smoke/CO alarm at least once a month; gently vacuum the outside of the smoke/CO alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at computer or office supply stores) may also be used. Follow manufacturer
instructions for use. Test the smoke/CO alarm. Never use water, cleaners or solvents since they may damage the unit.
• If the smoke/CO alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot
be cleaned to avoid unwanted alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the smoke/CO alarm and the environment in which it is installed. All the batteries
specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life,
you MUST replace the battery immediately once the unit starts “chirping” (the “Low Battery Warning”).
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
level, and an additional one in the kitchen. Have fire escape ladders or other reliable means of escape from an upper level in case stairs are blocked.

POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney
pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances
caused by outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty
winds. Heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Several appliances running at the same time
competing for limited fresh air.
• Vent pipe connections vibrating loose from clothes
dryers, furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs
which can amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your home. Since these conditions
can come and go, they are also hard to recreate during a CO investigation.
REGULATORY INFORMATION FOR SMOKE/CO ALARMS
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences The National Fire Protection Association (NFPA), recommends one smoke
alarm on every level, in every sleeping area, and in every bedroom. In new construction, the smoke alarms must be AC powered and
interconnected. See “Agency Placement Recommendations” for details. For additional coverage, it is recommended that you install a
smoke alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F
(4.4˚ C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the smoke alarms.
More specifically, install smoke alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each.
If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second level stairway, and at bottom of basement stairway.
Specific requirements for smoke alarm installation vary from state to state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/DC units be interconnected for added protection.
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and
exposure times as described below. They are measured in parts per million (ppm) of CO over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days.
CO alarms are designed to alarm before there is an immediate life threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect average, healthy adults, but after 4 hours the same level may cause headaches.
• An exposure to 400 ppm of CO may cause headaches in average, healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station Carbon Monoxide Alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1. 2: “Carbon monoxide alarms covered by these requirements are intended to respond
to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired
appliances, and fireplaces. CO alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of
Carbon Monoxide exposure.” This CO alarm monitors the air at the alarm, and is designed to alarm before CO levels become life threatening. This allows you
precious time to leave the house and correct the problem. This is only possible if alarms are located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The CO alarm is not formulated to detect CO levels below 30 ppm
typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm),
Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).

CALIFORNIA STATE FIRE MARSHAL (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke
alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or smoke alarms in the living rooms, dining rooms,
bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS
This smoke/CO alarm is intended for residential use. It is not intended for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide alarms must be met. The smoke alarm portion of this device is not intended to alert hearing impaired
residents. Special purpose smoke alarms should be installed for hearing impaired residents (CO alarms are not yet available for the hearing impaired).
Smoke/CO alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that everyone is involved – from kids to
grandparents. Allow children to master fire escape planning and practice before holding a fire drill at night when they are sleeping. If children or others do not
readily waken to the sound of the smoke/CO alarm, or if there are infants or family members with mobility limitations, make sure that someone is assigned to
assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill while family members are sleeping in order to determine
their response to the sound of the smoke/CO alarm while sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke/CO alarms cannot work without power. Battery operated units cannot work if the batteries are missing, disconnected
or dead, if the wrong type of batteries are used, or if the batteries are not installed correctly. AC units cannot work if the AC power
is cut off for any reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical fire that burns the
electrical wires, etc. ). If you are concerned about the limitations of battery or AC power, install both types of units.
This smoke/CO alarm will not sense smoke or CO that does not reach the sensors. It will only sense smoke or CO at the
sensor. Smoke or CO may be present in other areas. Doors or other obstructions may affect the rate at which CO or smoke
reaches the sensors. If bedroom doors are usually closed at night, we recommend you install an alarm device (Combination CO
and smoke alarm, or separate CO alarms and smoke alarms) in each bedroom and in the hallway between them.
This smoke/CO alarm may not sense smoke or CO on another level of the home. Example: This alarm device, installed on the second level, may
not sense smoke or CO in the basement. For this reason, one alarm device may not give adequate early warning. Recommended minimum protection
is one alarm device in every sleeping area, every bedroom, and on every level of your home. Some experts recommend battery powered Smoke
and CO alarms be used in conjunction with interconnected AC powered smoke alarms. For details, see “About Smoke Alarms” for details.
Smoke/CO alarms may not be heard. The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the smoke/CO alarm is installed outside the bedroom, it may not wake up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed or only partly open. Even persons who are awake may not hear the
alarm horn if the sound is blocked by distance or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or other appliances
may also prevent alert persons from hearing the alarm horn. This smoke/CO alarm is not intended for people who are hearing impaired.
The alarm may not have time to alarm before the fire itself causes damage, injury, or death, since smoke from
some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children
playing with matches, or fires caused by violent explosions resulting from escaping gas.
This smoke/CO alarm is not a substitute for life insurance. Though this smoke/CO alarm warns against increasing CO levels or the presence of
smoke, BRK Brands, Inc. does not warrant or imply in any way that they will protect lives. Homeowners and renters must still insure their lives.
This smoke/CO alarm has a limited life. Although this smoke/CO alarm and all of its parts have passed many stringent tests and are designed to be as reliable as
possible, any of these parts could fail at any time. Therefore, you must test this device weekly. The unit should be replaced immediately if it is not operating properly.
This smoke/CO alarm is not foolproof. Like all other electronic devices, this smoke/CO alarm has limitations. It can only detect smoke or CO that
reaches the sensors. It may not give early warning of the source of smoke or CO is in a remote part of the home, away from the alarm device.
ABOUT SMOKE ALARMS
Battery (DC) operated smoke alarms: Provide protection even when electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
AC powered smoke alarms: Can be interconnected so if one unit senses smoke, all units alarm. They do not operate if electricity fails. AC with battery (DC)
back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.
Smoke/CO alarms for solar or wind energy users and battery backup power systems: AC powered smoke/CO alarms should only be operated with
true or pure sine wave inverters. Operating this alarm with most battery-powered UPS (uninterruptible power supply) products or square wave or “quasi
sine wave” inverters will damage the alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
Smoke alarms for the hearing impaired: Special purpose smoke alarms should be installed for the hearing impaired. They include a visual alarm and an
audible alarm horn, and meet the requirements of the Americans With Disabilities Act. Can be interconnected so if one unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
All these smoke alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual,
and if smoke reaches the alarm. If you are unsure which type of unit to install, refer to National Fire Protection Association (NFPA) 72
(National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park,
Quincy, MA 02269-9101. Local building codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This smoke alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day care facilities, health care facilities, boarding houses, group
homes and dormitories provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or
porches. Using this smoke alarm in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This smoke alarm alone is not a suitable substitute for complete fire detection systems in places housing many people—like apartment buildings, condominiums,
hotels, motels, dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes of any kind. It is not a suitable substitute for
complete fire detection systems in warehouses, industrial facilities, commercial buildings, and special-purpose non-residential buildings which require special fire
detection and alarm systems. Depending on the building codes in your area, this smoke alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered smoke alarms only. In existing construction, AC, AC/DC, or DC powered
smoke alarms can be used as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety
Code), local building codes, or consult your Fire Department for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP PROGRAM
Certain HUD battery powered smoke alarm applications, especially those that fall under HUD 223(f) MAP (Multi-family Accelerated Processing),
may require a 10-Year sealed tamper resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

IF THE SMOKE ALARM SOUNDS:
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires
your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.
• Never remove the batteries from a battery operated smoke/CO alarm to stop an unwanted alarm (caused by cooking
smoke, etc.). Removing batteries disables the alarm so it cannot sense smoke, and removes your protection.
Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.
• Feel doors with the back of your hand before opening them. If a door is cool, open it slowly. Don’t open a
hot door. Keep doors and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside. Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home safer.
USING THE SILENCE FEATURES
Never deactivate the unit to quiet an unwanted alarm. Deactivating the alarm disables the unit and removes your protection.
The silence feature is intended to temporarily silence the horn while you identify and correct the problem. Do not use the silence
feature in emergency situations. It will not correct a CO problem or extinguish a fire. The silence feature can temporarily quiet an
unwanted alarm for several minutes. You can silence this smoke/CO alarm by pressing the Test/Silence button on the alarm cover
for at least 3-5 seconds. After the Test/Silence button is released, the Red LED blinks during the silence mode.
When the smoke alarm is silenced When the CO alarm is silenced
The smoke alarm will remain silent for up to
15 minutes, then return to normal operation.
If the smoke has not cleared–or continues to
increase–the device will go back into alarm.
The CO alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels remain potentially
dangerous the horn will start sounding again.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the Low Battery Warning “chirp”. You can silence the Low Battery Warning “chirp” by pressing the Test/
Silence button on the alarm.Once the Low Battery Warning “chirp” silence feature is activated, the unit continues to flash the Green light once a minute.
After time, the low battery “chirp” will resume. Replace the alarm as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into test mode and the Low
Battery Warning will resume (LED flashes and unit sounds “chirp” once a minute).
SILENCING THE END OF LIFE SIGNAL
This silence feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End
of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life
silence feature has been activated. After approximately 2 days, the End of Life “chirp” will resume.
WHAT YOU NEED TO KNOW ABOUT CO:
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are
exposed to heat (usually fire). Electrical appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real
danger now that homes are more energy efficient. “Air-tight” homes with added insulation, sealed windows, and other weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO alarm measures exposure to CO over time. It alarms if CO levels are extremely high in a short period of time, or if CO levels reach a
certain minimum over a long period of time. The CO alarm generally sounds an alarm before the onset of symptoms in average, healthy adults.
Why is this important? Because you need to be warned of a potential CO problem while you can still react in time. In many reported cases
of CO exposure, victims may be aware that they are not feeling well, but become disoriented and can no longer react well enough to exit the
building or get help. Also, young children and pets may be the first affected. The average healthy adult might not feel any symptoms when the
CO alarm sounds. However, people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be
more quickly and severely affected by CO. If you experience even mild symptoms of CO poisoning, consult your doctor immediately!
HOW CAN I PROTECT MY FAMILY FROM CO POISONING?
A CO alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become
threatening for average, healthy adults. A CO alarm is not a substitute for proper maintenance of home appliances.
TO HELP PREVENT CO PROBLEMS AND REDUCE THE RISK OF CO POISONING:
• Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks,
or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame
on the burner and pilot lights. The flame should be blue. A yellow flame means fuel is not being burned completely and CO may
be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all fuel-burning appliances.
Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window
or a door. Opening windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your CO alarm sounds.
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after
an alarm. These are a few of the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK
Brands, Inc. shall not be obligated to pay for any carbon monoxide investigation or service call.
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM
Type of Alarm What You See and Hear
Carbon Monoxide (CO)
Voice: “Warning, evacuate carbon monoxide in [Location,
example: “Hallway”]. Evacuate.” “____ ppm.”
Horn: 4 beeps, pause, 4 beeps, voice LED: Flashes Red
Smoke Voice: “Warning, evacuate smoke in [Location, example: “Hallway”]. Evacuate.”
Horn: 3 beeps, pause, 3 beeps, voice LED: Flashes Red
Alarms have various limitations. See “General
Limitations of smoke/CO alarms” for details.
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing, move
everyone to a source of fresh air. DO NOT deactivate the alarm!
IF THE CO ALARM SOUNDS
Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can kill you.
In other words, when your CO alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Press the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the number of your local emergency service here:
____________________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are
accounted for. Do not re-enter the premises, or move away from the open door or window until the emergency services
responder has arrived, the premises have been aired out, and your CO alarm remains in its normal condition.
4. After following steps 1-3, if your CO alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate
for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this
inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not,
and have not, been operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here:
____________________________________________________________________
NOTE: A qualified appliance technician is defined as “a person, firm, corporation, or company that either in person or through a
representative, is engaged in and responsible for the installation, testing, servicing, or replacement of heating, ventilation, air conditioning
(HVAC) equipment, combustion appliances and equipment, and/or gas fireplaces or other decorative combustion equipment.”
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and your CO alarm remains in its normal
condition, you can check what the highest carbon monoxide level sensed was:
Action: Alarm Will Say:
Press & hold test button
“Highest carbon monoxide level was ___ ppm. Please see manual.”
“To clear highest carbon monoxide level,
press and hold test button now.”
Press & hold test button, if you would like to clear
the highest level sensed. If you would like to keep the
highest level in memory, do not press anything.
“Highest carbon monoxide level cleared.” alarm will say nothing.

POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney
pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances
caused by outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty
winds. Heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Several appliances running at the same time
competing for limited fresh air.
• Vent pipe connections vibrating loose from clothes
dryers, furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs
which can amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your home. Since these conditions
can come and go, they are also hard to recreate during a CO investigation.
REGULATORY INFORMATION FOR SMOKE/CO ALARMS
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences The National Fire Protection Association (NFPA), recommends one smoke
alarm on every level, in every sleeping area, and in every bedroom. In new construction, the smoke alarms must be AC powered and
interconnected. See “Agency Placement Recommendations” for details. For additional coverage, it is recommended that you install a
smoke alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F
(4.4˚ C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the smoke alarms.
More specifically, install smoke alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each.
If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second level stairway, and at bottom of basement stairway.
Specific requirements for smoke alarm installation vary from state to state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/DC units be interconnected for added protection.
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and
exposure times as described below. They are measured in parts per million (ppm) of CO over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days.
CO alarms are designed to alarm before there is an immediate life threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect average, healthy adults, but after 4 hours the same level may cause headaches.
• An exposure to 400 ppm of CO may cause headaches in average, healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station Carbon Monoxide Alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1. 2: “Carbon monoxide alarms covered by these requirements are intended to respond
to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired
appliances, and fireplaces. CO alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of
Carbon Monoxide exposure.” This CO alarm monitors the air at the alarm, and is designed to alarm before CO levels become life threatening. This allows you
precious time to leave the house and correct the problem. This is only possible if alarms are located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The CO alarm is not formulated to detect CO levels below 30 ppm
typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm),
Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
AGENCY PLACEMENT RECOMMENDATIONS

CALIFORNIA STATE FIRE MARSHAL (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke
alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or smoke alarms in the living rooms, dining rooms,
bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS
This smoke/CO alarm is intended for residential use. It is not intended for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide alarms must be met. The smoke alarm portion of this device is not intended to alert hearing impaired
residents. Special purpose smoke alarms should be installed for hearing impaired residents (CO alarms are not yet available for the hearing impaired).
Smoke/CO alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that everyone is involved – from kids to
grandparents. Allow children to master fire escape planning and practice before holding a fire drill at night when they are sleeping. If children or others do not
readily waken to the sound of the smoke/CO alarm, or if there are infants or family members with mobility limitations, make sure that someone is assigned to
assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill while family members are sleeping in order to determine
their response to the sound of the smoke/CO alarm while sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke/CO alarms cannot work without power. Battery operated units cannot work if the batteries are missing, disconnected
or dead, if the wrong type of batteries are used, or if the batteries are not installed correctly. AC units cannot work if the AC power
is cut off for any reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical fire that burns the
electrical wires, etc. ). If you are concerned about the limitations of battery or AC power, install both types of units.
This smoke/CO alarm will not sense smoke or CO that does not reach the sensors. It will only sense smoke or CO at the
sensor. Smoke or CO may be present in other areas. Doors or other obstructions may affect the rate at which CO or smoke
reaches the sensors. If bedroom doors are usually closed at night, we recommend you install an alarm device (Combination CO
and smoke alarm, or separate CO alarms and smoke alarms) in each bedroom and in the hallway between them.
This smoke/CO alarm may not sense smoke or CO on another level of the home. Example: This alarm device, installed on the second level, may
not sense smoke or CO in the basement. For this reason, one alarm device may not give adequate early warning. Recommended minimum protection
is one alarm device in every sleeping area, every bedroom, and on every level of your home. Some experts recommend battery powered Smoke
and CO alarms be used in conjunction with interconnected AC powered smoke alarms. For details, see “About Smoke Alarms” for details.
Smoke/CO alarms may not be heard. The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the smoke/CO alarm is installed outside the bedroom, it may not wake up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed or only partly open. Even persons who are awake may not hear the
alarm horn if the sound is blocked by distance or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or other appliances
may also prevent alert persons from hearing the alarm horn. This smoke/CO alarm is not intended for people who are hearing impaired.
The alarm may not have time to alarm before the fire itself causes damage, injury, or death, since smoke from
some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children
playing with matches, or fires caused by violent explosions resulting from escaping gas.
This smoke/CO alarm is not a substitute for life insurance. Though this smoke/CO alarm warns against increasing CO levels or the presence of
smoke, BRK Brands, Inc. does not warrant or imply in any way that they will protect lives. Homeowners and renters must still insure their lives.
This smoke/CO alarm has a limited life. Although this smoke/CO alarm and all of its parts have passed many stringent tests and are designed to be as reliable as
possible, any of these parts could fail at any time. Therefore, you must test this device weekly. The unit should be replaced immediately if it is not operating properly.
This smoke/CO alarm is not foolproof. Like all other electronic devices, this smoke/CO alarm has limitations. It can only detect smoke or CO that
reaches the sensors. It may not give early warning of the source of smoke or CO is in a remote part of the home, away from the alarm device.
ABOUT SMOKE ALARMS
Battery (DC) operated smoke alarms: Provide protection even when electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
AC powered smoke alarms: Can be interconnected so if one unit senses smoke, all units alarm. They do not operate if electricity fails. AC with battery (DC)
back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.
Smoke/CO alarms for solar or wind energy users and battery backup power systems: AC powered smoke/CO alarms should only be operated with
true or pure sine wave inverters. Operating this alarm with most battery-powered UPS (uninterruptible power supply) products or square wave or “quasi
sine wave” inverters will damage the alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
Smoke alarms for the hearing impaired: Special purpose smoke alarms should be installed for the hearing impaired. They include a visual alarm and an
audible alarm horn, and meet the requirements of the Americans With Disabilities Act. Can be interconnected so if one unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
All these smoke alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual,
and if smoke reaches the alarm. If you are unsure which type of unit to install, refer to National Fire Protection Association (NFPA) 72
(National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park,
Quincy, MA 02269-9101. Local building codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This smoke alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day care facilities, health care facilities, boarding houses, group
homes and dormitories provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or
porches. Using this smoke alarm in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This smoke alarm alone is not a suitable substitute for complete fire detection systems in places housing many people—like apartment buildings, condominiums,
hotels, motels, dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes of any kind. It is not a suitable substitute for
complete fire detection systems in warehouses, industrial facilities, commercial buildings, and special-purpose non-residential buildings which require special fire
detection and alarm systems. Depending on the building codes in your area, this smoke alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered smoke alarms only. In existing construction, AC, AC/DC, or DC powered
smoke alarms can be used as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety
Code), local building codes, or consult your Fire Department for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP PROGRAM
Certain HUD battery powered smoke alarm applications, especially those that fall under HUD 223(f) MAP (Multi-family Accelerated Processing),
may require a 10-Year sealed tamper resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

IF THE SMOKE ALARM SOUNDS:
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires
your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.
• Never remove the batteries from a battery operated smoke/CO alarm to stop an unwanted alarm (caused by cooking
smoke, etc.). Removing batteries disables the alarm so it cannot sense smoke, and removes your protection.
Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.
• Feel doors with the back of your hand before opening them. If a door is cool, open it slowly. Don’t open a
hot door. Keep doors and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside. Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home safer.
USING THE SILENCE FEATURES
Never deactivate the unit to quiet an unwanted alarm. Deactivating the alarm disables the unit and removes your protection.
The silence feature is intended to temporarily silence the horn while you identify and correct the problem. Do not use the silence
feature in emergency situations. It will not correct a CO problem or extinguish a fire. The silence feature can temporarily quiet an
unwanted alarm for several minutes. You can silence this smoke/CO alarm by pressing the Test/Silence button on the alarm cover
for at least 3-5 seconds. After the Test/Silence button is released, the Red LED blinks during the silence mode.
When the smoke alarm is silenced When the CO alarm is silenced
The smoke alarm will remain silent for up to
15 minutes, then return to normal operation.
If the smoke has not cleared–or continues to
increase–the device will go back into alarm.
The CO alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels remain potentially
dangerous the horn will start sounding again.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the Low Battery Warning “chirp”. You can silence the Low Battery Warning “chirp” by pressing the Test/
Silence button on the alarm.Once the Low Battery Warning “chirp” silence feature is activated, the unit continues to flash the Green light once a minute.
After time, the low battery “chirp” will resume. Replace the alarm as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into test mode and the Low
Battery Warning will resume (LED flashes and unit sounds “chirp” once a minute).
SILENCING THE END OF LIFE SIGNAL
This silence feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End
of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life
silence feature has been activated. After approximately 2 days, the End of Life “chirp” will resume.
WHAT YOU NEED TO KNOW ABOUT CO:
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are
exposed to heat (usually fire). Electrical appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real
danger now that homes are more energy efficient. “Air-tight” homes with added insulation, sealed windows, and other weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO alarm measures exposure to CO over time. It alarms if CO levels are extremely high in a short period of time, or if CO levels reach a
certain minimum over a long period of time. The CO alarm generally sounds an alarm before the onset of symptoms in average, healthy adults.
Why is this important? Because you need to be warned of a potential CO problem while you can still react in time. In many reported cases
of CO exposure, victims may be aware that they are not feeling well, but become disoriented and can no longer react well enough to exit the
building or get help. Also, young children and pets may be the first affected. The average healthy adult might not feel any symptoms when the
CO alarm sounds. However, people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be
more quickly and severely affected by CO. If you experience even mild symptoms of CO poisoning, consult your doctor immediately!
HOW CAN I PROTECT MY FAMILY FROM CO POISONING?
A CO alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become
threatening for average, healthy adults. A CO alarm is not a substitute for proper maintenance of home appliances.
TO HELP PREVENT CO PROBLEMS AND REDUCE THE RISK OF CO POISONING:
• Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks,
or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame
on the burner and pilot lights. The flame should be blue. A yellow flame means fuel is not being burned completely and CO may
be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all fuel-burning appliances.
Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window
or a door. Opening windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your CO alarm sounds.
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after
an alarm. These are a few of the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK
Brands, Inc. shall not be obligated to pay for any carbon monoxide investigation or service call.
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM
Type of Alarm What You See and Hear
Carbon Monoxide (CO)
Voice: “Warning, evacuate carbon monoxide in [Location,
example: “Hallway”]. Evacuate.” “____ ppm.”
Horn: 4 beeps, pause, 4 beeps, voice LED: Flashes Red
Smoke Voice: “Warning, evacuate smoke in [Location, example: “Hallway”]. Evacuate.”
Horn: 3 beeps, pause, 3 beeps, voice LED: Flashes Red
Alarms have various limitations. See “General
Limitations of smoke/CO alarms” for details.
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing, move
everyone to a source of fresh air. DO NOT deactivate the alarm!
IF THE CO ALARM SOUNDS
Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can kill you.
In other words, when your CO alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Press the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the number of your local emergency service here:
____________________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are
accounted for. Do not re-enter the premises, or move away from the open door or window until the emergency services
responder has arrived, the premises have been aired out, and your CO alarm remains in its normal condition.
4. After following steps 1-3, if your CO alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate
for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this
inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not,
and have not, been operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here:

POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney
pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances
caused by outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty
winds. Heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Several appliances running at the same time
competing for limited fresh air.
• Vent pipe connections vibrating loose from clothes
dryers, furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs
which can amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your home. Since these conditions
can come and go, they are also hard to recreate during a CO investigation.
REGULATORY INFORMATION FOR SMOKE/CO ALARMS
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences The National Fire Protection Association (NFPA), recommends one smoke
alarm on every level, in every sleeping area, and in every bedroom. In new construction, the smoke alarms must be AC powered and
interconnected. See “Agency Placement Recommendations” for details. For additional coverage, it is recommended that you install a
smoke alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F
(4.4˚ C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the smoke alarms.
More specifically, install smoke alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each.
If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second level stairway, and at bottom of basement stairway.
Specific requirements for smoke alarm installation vary from state to state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/DC units be interconnected for added protection.
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and
exposure times as described below. They are measured in parts per million (ppm) of CO over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days.
CO alarms are designed to alarm before there is an immediate life threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect average, healthy adults, but after 4 hours the same level may cause headaches.
• An exposure to 400 ppm of CO may cause headaches in average, healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station Carbon Monoxide Alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1. 2: “Carbon monoxide alarms covered by these requirements are intended to respond
to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired
appliances, and fireplaces. CO alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of
Carbon Monoxide exposure.” This CO alarm monitors the air at the alarm, and is designed to alarm before CO levels become life threatening. This allows you
precious time to leave the house and correct the problem. This is only possible if alarms are located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The CO alarm is not formulated to detect CO levels below 30 ppm
typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm),
Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
AGENCY PLACEMENT RECOMMENDATIONS

CALIFORNIA STATE FIRE MARSHAL (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke
alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or smoke alarms in the living rooms, dining rooms,
bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS
This smoke/CO alarm is intended for residential use. It is not intended for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide alarms must be met. The smoke alarm portion of this device is not intended to alert hearing impaired
residents. Special purpose smoke alarms should be installed for hearing impaired residents (CO alarms are not yet available for the hearing impaired).
Smoke/CO alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that everyone is involved – from kids to
grandparents. Allow children to master fire escape planning and practice before holding a fire drill at night when they are sleeping. If children or others do not
readily waken to the sound of the smoke/CO alarm, or if there are infants or family members with mobility limitations, make sure that someone is assigned to
assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill while family members are sleeping in order to determine
their response to the sound of the smoke/CO alarm while sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke/CO alarms cannot work without power. Battery operated units cannot work if the batteries are missing, disconnected
or dead, if the wrong type of batteries are used, or if the batteries are not installed correctly. AC units cannot work if the AC power
is cut off for any reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical fire that burns the
electrical wires, etc. ). If you are concerned about the limitations of battery or AC power, install both types of units.
This smoke/CO alarm will not sense smoke or CO that does not reach the sensors. It will only sense smoke or CO at the
sensor. Smoke or CO may be present in other areas. Doors or other obstructions may affect the rate at which CO or smoke
reaches the sensors. If bedroom doors are usually closed at night, we recommend you install an alarm device (Combination CO
and smoke alarm, or separate CO alarms and smoke alarms) in each bedroom and in the hallway between them.
This smoke/CO alarm may not sense smoke or CO on another level of the home. Example: This alarm device, installed on the second level, may
not sense smoke or CO in the basement. For this reason, one alarm device may not give adequate early warning. Recommended minimum protection
is one alarm device in every sleeping area, every bedroom, and on every level of your home. Some experts recommend battery powered Smoke
and CO alarms be used in conjunction with interconnected AC powered smoke alarms. For details, see “About Smoke Alarms” for details.
Smoke/CO alarms may not be heard. The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the smoke/CO alarm is installed outside the bedroom, it may not wake up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed or only partly open. Even persons who are awake may not hear the
alarm horn if the sound is blocked by distance or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or other appliances
may also prevent alert persons from hearing the alarm horn. This smoke/CO alarm is not intended for people who are hearing impaired.
The alarm may not have time to alarm before the fire itself causes damage, injury, or death, since smoke from
some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children
playing with matches, or fires caused by violent explosions resulting from escaping gas.
This smoke/CO alarm is not a substitute for life insurance. Though this smoke/CO alarm warns against increasing CO levels or the presence of
smoke, BRK Brands, Inc. does not warrant or imply in any way that they will protect lives. Homeowners and renters must still insure their lives.
This smoke/CO alarm has a limited life. Although this smoke/CO alarm and all of its parts have passed many stringent tests and are designed to be as reliable as
possible, any of these parts could fail at any time. Therefore, you must test this device weekly. The unit should be replaced immediately if it is not operating properly.
This smoke/CO alarm is not foolproof. Like all other electronic devices, this smoke/CO alarm has limitations. It can only detect smoke or CO that
reaches the sensors. It may not give early warning of the source of smoke or CO is in a remote part of the home, away from the alarm device.
ABOUT SMOKE ALARMS
Battery (DC) operated smoke alarms: Provide protection even when electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
AC powered smoke alarms: Can be interconnected so if one unit senses smoke, all units alarm. They do not operate if electricity fails. AC with battery (DC)
back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.
Smoke/CO alarms for solar or wind energy users and battery backup power systems: AC powered smoke/CO alarms should only be operated with
true or pure sine wave inverters. Operating this alarm with most battery-powered UPS (uninterruptible power supply) products or square wave or “quasi
sine wave” inverters will damage the alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
Smoke alarms for the hearing impaired: Special purpose smoke alarms should be installed for the hearing impaired. They include a visual alarm and an
audible alarm horn, and meet the requirements of the Americans With Disabilities Act. Can be interconnected so if one unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
All these smoke alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual,
and if smoke reaches the alarm. If you are unsure which type of unit to install, refer to National Fire Protection Association (NFPA) 72
(National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park,
Quincy, MA 02269-9101. Local building codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This smoke alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day care facilities, health care facilities, boarding houses, group
homes and dormitories provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or
porches. Using this smoke alarm in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This smoke alarm alone is not a suitable substitute for complete fire detection systems in places housing many people—like apartment buildings, condominiums,
hotels, motels, dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes of any kind. It is not a suitable substitute for
complete fire detection systems in warehouses, industrial facilities, commercial buildings, and special-purpose non-residential buildings which require special fire
detection and alarm systems. Depending on the building codes in your area, this smoke alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered smoke alarms only. In existing construction, AC, AC/DC, or DC powered
smoke alarms can be used as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety
Code), local building codes, or consult your Fire Department for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP PROGRAM
Certain HUD battery powered smoke alarm applications, especially those that fall under HUD 223(f) MAP (Multi-family Accelerated Processing),
may require a 10-Year sealed tamper resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

IF THE SMOKE ALARM SOUNDS:
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires
your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.
• Never remove the batteries from a battery operated smoke/CO alarm to stop an unwanted alarm (caused by cooking
smoke, etc.). Removing batteries disables the alarm so it cannot sense smoke, and removes your protection.
Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.
• Feel doors with the back of your hand before opening them. If a door is cool, open it slowly. Don’t open a
hot door. Keep doors and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside. Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home safer.
USING THE SILENCE FEATURES
Never deactivate the unit to quiet an unwanted alarm. Deactivating the alarm disables the unit and removes your protection.
The silence feature is intended to temporarily silence the horn while you identify and correct the problem. Do not use the silence
feature in emergency situations. It will not correct a CO problem or extinguish a fire. The silence feature can temporarily quiet an
unwanted alarm for several minutes. You can silence this smoke/CO alarm by pressing the Test/Silence button on the alarm cover
for at least 3-5 seconds. After the Test/Silence button is released, the Red LED blinks during the silence mode.
When the smoke alarm is silenced When the CO alarm is silenced
The smoke alarm will remain silent for up to
15 minutes, then return to normal operation.
If the smoke has not cleared–or continues to
increase–the device will go back into alarm.
The CO alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels remain potentially
dangerous the horn will start sounding again.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the Low Battery Warning “chirp”. You can silence the Low Battery Warning “chirp” by pressing the Test/
Silence button on the alarm.Once the Low Battery Warning “chirp” silence feature is activated, the unit continues to flash the Green light once a minute.
After time, the low battery “chirp” will resume. Replace the alarm as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into test mode and the Low
Battery Warning will resume (LED flashes and unit sounds “chirp” once a minute).
SILENCING THE END OF LIFE SIGNAL
This silence feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End
of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life
silence feature has been activated. After approximately 2 days, the End of Life “chirp” will resume.
WHAT YOU NEED TO KNOW ABOUT CO:
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are
exposed to heat (usually fire). Electrical appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real
danger now that homes are more energy efficient. “Air-tight” homes with added insulation, sealed windows, and other weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO alarm measures exposure to CO over time. It alarms if CO levels are extremely high in a short period of time, or if CO levels reach a
certain minimum over a long period of time. The CO alarm generally sounds an alarm before the onset of symptoms in average, healthy adults.
Why is this important? Because you need to be warned of a potential CO problem while you can still react in time. In many reported cases
of CO exposure, victims may be aware that they are not feeling well, but become disoriented and can no longer react well enough to exit the
building or get help. Also, young children and pets may be the first affected. The average healthy adult might not feel any symptoms when the
CO alarm sounds. However, people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be
more quickly and severely affected by CO. If you experience even mild symptoms of CO poisoning, consult your doctor immediately!
HOW CAN I PROTECT MY FAMILY FROM CO POISONING?
A CO alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become
threatening for average, healthy adults. A CO alarm is not a substitute for proper maintenance of home appliances.
TO HELP PREVENT CO PROBLEMS AND REDUCE THE RISK OF CO POISONING:
• Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks,
or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame
on the burner and pilot lights. The flame should be blue. A yellow flame means fuel is not being burned completely and CO may
be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all fuel-burning appliances.
Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window
or a door. Opening windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your CO alarm sounds.
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after
an alarm. These are a few of the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK
Brands, Inc. shall not be obligated to pay for any carbon monoxide investigation or service call.
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM
Type of Alarm What You See and Hear
Carbon Monoxide (CO)
Voice: “Warning, evacuate carbon monoxide in [Location,
example: “Hallway”]. Evacuate.” “____ ppm.”
Horn: 4 beeps, pause, 4 beeps, voice LED: Flashes Red
Smoke Voice: “Warning, evacuate smoke in [Location, example: “Hallway”]. Evacuate.”
Horn: 3 beeps, pause, 3 beeps, voice LED: Flashes Red
Alarms have various limitations. See “General
Limitations of smoke/CO alarms” for details.
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing, move
everyone to a source of fresh air. DO NOT deactivate the alarm!
IF THE CO ALARM SOUNDS
Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can kill you.
In other words, when your CO alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Press the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the number of your local emergency service here:
____________________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are
accounted for. Do not re-enter the premises, or move away from the open door or window until the emergency services
responder has arrived, the premises have been aired out, and your CO alarm remains in its normal condition.
4. After following steps 1-3, if your CO alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate
for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this
inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not,
and have not, been operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here:
____________________________________________________________________
NOTE: A qualified appliance technician is defined as “a person, firm, corporation, or company that either in person or through a
representative, is engaged in and responsible for the installation, testing, servicing, or replacement of heating, ventilation, air conditioning
(HVAC) equipment, combustion appliances and equipment, and/or gas fireplaces or other decorative combustion equipment.”
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and your CO alarm remains in its normal
condition, you can check what the highest carbon monoxide level sensed was:
Action: Alarm Will Say:
Press & hold test button
“Highest carbon monoxide level was ___ ppm. Please see manual.”
“To clear highest carbon monoxide level,
press and hold test button now.”
Press & hold test button, if you would like to clear
the highest level sensed. If you would like to keep the
highest level in memory, do not press anything.
“Highest carbon monoxide level cleared.” alarm will say nothing.

POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney
pipe or flue, or cracked heat exchanger, blocked or clogged chimney opening.
Improper use of appliance/device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances
caused by outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty
winds. Heavy air in the vent pipes (cold/humid air
with extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Several appliances running at the same time
competing for limited fresh air.
• Vent pipe connections vibrating loose from clothes
dryers, furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs
which can amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your home. Since these conditions
can come and go, they are also hard to recreate during a CO investigation.
REGULATORY INFORMATION FOR SMOKE/CO ALARMS
REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences The National Fire Protection Association (NFPA), recommends one smoke
alarm on every level, in every sleeping area, and in every bedroom. In new construction, the smoke alarms must be AC powered and
interconnected. See “Agency Placement Recommendations” for details. For additional coverage, it is recommended that you install a
smoke alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40˚ F
(4.4˚ C) and 100˚ F (37.8˚ C). Make sure no door or other obstruction could keep smoke from reaching the smoke alarms.
More specifically, install smoke alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with doors closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each.
If a hall is over 40 feet (12 meters) long, install an alarm at each end.
• At the top of the first-to-second level stairway, and at bottom of basement stairway.
Specific requirements for smoke alarm installation vary from state to state and from region to region. Check with your local Fire Department
for current requirements in your area. It is recommended AC or AC/DC units be interconnected for added protection.
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and
exposure times as described below. They are measured in parts per million (ppm) of CO over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM BETWEEN 60 and 240 MINUTES.
* Approximately 10% COHb exposure at levels of 10% to 95% Relative Humidity (RH).
The unit is designed not to alarm when exposed to a constant level of 30 ppm for 30 days.
CO alarms are designed to alarm before there is an immediate life threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect average, healthy adults, but after 4 hours the same level may cause headaches.
• An exposure to 400 ppm of CO may cause headaches in average, healthy adults after 35 minutes, but can cause death after 2 hours.
Standards: Underwriters Laboratories Inc. Single and Multiple Station Carbon Monoxide Alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1. 2: “Carbon monoxide alarms covered by these requirements are intended to respond
to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal operation of fuel-fired
appliances, and fireplaces. CO alarms are intended to alarm at carbon monoxide levels below those that could cause a loss of ability to react to the dangers of
Carbon Monoxide exposure.” This CO alarm monitors the air at the alarm, and is designed to alarm before CO levels become life threatening. This allows you
precious time to leave the house and correct the problem. This is only possible if alarms are located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges: The CO alarm is not formulated to detect CO levels below 30 ppm
typically. UL tested for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm),
Isopropyl Alcohol (200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
AGENCY PLACEMENT RECOMMENDATIONS

CALIFORNIA STATE FIRE MARSHAL (CSFM)
Early warning detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke
alarm installed in each separate sleeping area (in the vicinity, but outside bedrooms), and Heat or smoke alarms in the living rooms, dining rooms,
bedrooms, kitchens, hallways, finished attics, furnace rooms, closets, utility and storage rooms, basements, and attached garages.
GENERAL LIMITATIONS OF SMOKE/CO ALARMS
This smoke/CO alarm is intended for residential use. It is not intended for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide alarms must be met. The smoke alarm portion of this device is not intended to alert hearing impaired
residents. Special purpose smoke alarms should be installed for hearing impaired residents (CO alarms are not yet available for the hearing impaired).
Smoke/CO alarms may not waken all individuals. Practice the escape plan at least twice a year, making sure that everyone is involved – from kids to
grandparents. Allow children to master fire escape planning and practice before holding a fire drill at night when they are sleeping. If children or others do not
readily waken to the sound of the smoke/CO alarm, or if there are infants or family members with mobility limitations, make sure that someone is assigned to
assist them in fire drill and in the event of an emergency. It is recommended that you hold a fire drill while family members are sleeping in order to determine
their response to the sound of the smoke/CO alarm while sleeping and to determine whether they may need assistance in the event of an emergency.
Smoke/CO alarms cannot work without power. Battery operated units cannot work if the batteries are missing, disconnected
or dead, if the wrong type of batteries are used, or if the batteries are not installed correctly. AC units cannot work if the AC power
is cut off for any reason (open fuse or circuit breaker, failure along a power line or at a power station, electrical fire that burns the
electrical wires, etc. ). If you are concerned about the limitations of battery or AC power, install both types of units.
This smoke/CO alarm will not sense smoke or CO that does not reach the sensors. It will only sense smoke or CO at the
sensor. Smoke or CO may be present in other areas. Doors or other obstructions may affect the rate at which CO or smoke
reaches the sensors. If bedroom doors are usually closed at night, we recommend you install an alarm device (Combination CO
and smoke alarm, or separate CO alarms and smoke alarms) in each bedroom and in the hallway between them.
This smoke/CO alarm may not sense smoke or CO on another level of the home. Example: This alarm device, installed on the second level, may
not sense smoke or CO in the basement. For this reason, one alarm device may not give adequate early warning. Recommended minimum protection
is one alarm device in every sleeping area, every bedroom, and on every level of your home. Some experts recommend battery powered Smoke
and CO alarms be used in conjunction with interconnected AC powered smoke alarms. For details, see “About Smoke Alarms” for details.
Smoke/CO alarms may not be heard. The alarm horn loudness meets or exceeds current UL standards of 85 dB at 10 feet (3 meters). However,
if the smoke/CO alarm is installed outside the bedroom, it may not wake up a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This is especially true if the door is closed or only partly open. Even persons who are awake may not hear the
alarm horn if the sound is blocked by distance or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or other appliances
may also prevent alert persons from hearing the alarm horn. This smoke/CO alarm is not intended for people who are hearing impaired.
The alarm may not have time to alarm before the fire itself causes damage, injury, or death, since smoke from
some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children
playing with matches, or fires caused by violent explosions resulting from escaping gas.
This smoke/CO alarm is not a substitute for life insurance. Though this smoke/CO alarm warns against increasing CO levels or the presence of
smoke, BRK Brands, Inc. does not warrant or imply in any way that they will protect lives. Homeowners and renters must still insure their lives.
This smoke/CO alarm has a limited life. Although this smoke/CO alarm and all of its parts have passed many stringent tests and are designed to be as reliable as
possible, any of these parts could fail at any time. Therefore, you must test this device weekly. The unit should be replaced immediately if it is not operating properly.
This smoke/CO alarm is not foolproof. Like all other electronic devices, this smoke/CO alarm has limitations. It can only detect smoke or CO that
reaches the sensors. It may not give early warning of the source of smoke or CO is in a remote part of the home, away from the alarm device.
ABOUT SMOKE ALARMS
Battery (DC) operated smoke alarms: Provide protection even when electricity fails, provided the batteries are
fresh and correctly installed. Units are easy to install, and do not require professional installation.
AC powered smoke alarms: Can be interconnected so if one unit senses smoke, all units alarm. They do not operate if electricity fails. AC with battery (DC)
back-up: will operate if electricity fails, provided the batteries are fresh and correctly installed. AC and AC/DC units must be installed by a qualified electrician.
Smoke/CO alarms for solar or wind energy users and battery backup power systems: AC powered smoke/CO alarms should only be operated with
true or pure sine wave inverters. Operating this alarm with most battery-powered UPS (uninterruptible power supply) products or square wave or “quasi
sine wave” inverters will damage the alarm. If you are not sure about your inverter or UPS type, please consult with the manufacturer to verify.
Smoke alarms for the hearing impaired: Special purpose smoke alarms should be installed for the hearing impaired. They include a visual alarm and an
audible alarm horn, and meet the requirements of the Americans With Disabilities Act. Can be interconnected so if one unit senses smoke, all units alarm.
Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
All these smoke alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual,
and if smoke reaches the alarm. If you are unsure which type of unit to install, refer to National Fire Protection Association (NFPA) 72
(National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One Batterymarch Park,
Quincy, MA 02269-9101. Local building codes may also require specific units in new construction or in different areas of the home.
SPECIAL COMPLIANCE CONSIDERATIONS
This smoke alarm is suitable for use in apartments, condominiums, townhouses, hospitals, day care facilities, health care facilities, boarding houses, group
homes and dormitories provided a primary fire detection system already exists to meet fire detection requirements in common areas like lobbies, hallways, or
porches. Using this smoke alarm in common areas may not provide sufficient warning to all residents or meet local fire protection ordinances/regulations.
This smoke alarm alone is not a suitable substitute for complete fire detection systems in places housing many people—like apartment buildings, condominiums,
hotels, motels, dormitories, hospitals, health care facilities, nursing homes, day care facilities, or group homes of any kind. It is not a suitable substitute for
complete fire detection systems in warehouses, industrial facilities, commercial buildings, and special-purpose non-residential buildings which require special fire
detection and alarm systems. Depending on the building codes in your area, this smoke alarm may be used to provide additional protection in these facilities.
In new construction, most building codes require the use of AC or AC/DC powered smoke alarms only. In existing construction, AC, AC/DC, or DC powered
smoke alarms can be used as specified by local building codes. Refer to NFPA 72 (National Fire Alarm and Signaling Code) and NFPA 101 (Life Safety
Code), local building codes, or consult your Fire Department for detailed fire protection requirements in buildings not defined as “households”.
HUD MAP PROGRAM
Certain HUD battery powered smoke alarm applications, especially those that fall under HUD 223(f) MAP (Multi-family Accelerated Processing),
may require a 10-Year sealed tamper resistant battery. This alarm does not meet that requirement. Substitute First Alert SA340B.

IF THE SMOKE ALARM SOUNDS:
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires
your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.
• Never remove the batteries from a battery operated smoke/CO alarm to stop an unwanted alarm (caused by cooking
smoke, etc.). Removing batteries disables the alarm so it cannot sense smoke, and removes your protection.
Instead open a window or fan the smoke away from the unit. The alarm will reset automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.
• Feel doors with the back of your hand before opening them. If a door is cool, open it slowly. Don’t open a
hot door. Keep doors and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside. Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home safer.
USING THE SILENCE FEATURES
Never deactivate the unit to quiet an unwanted alarm. Deactivating the alarm disables the unit and removes your protection.
The silence feature is intended to temporarily silence the horn while you identify and correct the problem. Do not use the silence
feature in emergency situations. It will not correct a CO problem or extinguish a fire. The silence feature can temporarily quiet an
unwanted alarm for several minutes. You can silence this smoke/CO alarm by pressing the Test/Silence button on the alarm cover
for at least 3-5 seconds. After the Test/Silence button is released, the Red LED blinks during the silence mode.
When the smoke alarm is silenced When the CO alarm is silenced
The smoke alarm will remain silent for up to
15 minutes, then return to normal operation.
If the smoke has not cleared–or continues to
increase–the device will go back into alarm.
The CO alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels remain potentially
dangerous the horn will start sounding again.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the Low Battery Warning “chirp”. You can silence the Low Battery Warning “chirp” by pressing the Test/
Silence button on the alarm.Once the Low Battery Warning “chirp” silence feature is activated, the unit continues to flash the Green light once a minute.
After time, the low battery “chirp” will resume. Replace the alarm as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into test mode and the Low
Battery Warning will resume (LED flashes and unit sounds “chirp” once a minute).
SILENCING THE END OF LIFE SIGNAL
This silence feature can temporarily quiet the End of Life warning “chirp” for up to 2 days. You can silence the End
of Life warning “chirp” by pressing the Test/Silence button. The horn will chirp, acknowledging that the End of Life
silence feature has been activated. After approximately 2 days, the End of Life “chirp” will resume.
WHAT YOU NEED TO KNOW ABOUT CO:
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not burn completely, or are
exposed to heat (usually fire). Electrical appliances typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real
danger now that homes are more energy efficient. “Air-tight” homes with added insulation, sealed windows, and other weatherproofing can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure: Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Convulsions, unconsciousness, heart and lung failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO alarm measures exposure to CO over time. It alarms if CO levels are extremely high in a short period of time, or if CO levels reach a
certain minimum over a long period of time. The CO alarm generally sounds an alarm before the onset of symptoms in average, healthy adults.
Why is this important? Because you need to be warned of a potential CO problem while you can still react in time. In many reported cases
of CO exposure, victims may be aware that they are not feeling well, but become disoriented and can no longer react well enough to exit the
building or get help. Also, young children and pets may be the first affected. The average healthy adult might not feel any symptoms when the
CO alarm sounds. However, people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be
more quickly and severely affected by CO. If you experience even mild symptoms of CO poisoning, consult your doctor immediately!
HOW CAN I PROTECT MY FAMILY FROM CO POISONING?
A CO alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become
threatening for average, healthy adults. A CO alarm is not a substitute for proper maintenance of home appliances.
TO HELP PREVENT CO PROBLEMS AND REDUCE THE RISK OF CO POISONING:
• Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks,
or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame
on the burner and pilot lights. The flame should be blue. A yellow flame means fuel is not being burned completely and CO may
be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all fuel-burning appliances.
Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window
or a door. Opening windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your CO alarm sounds.
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after
an alarm. These are a few of the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK
Brands, Inc. shall not be obligated to pay for any carbon monoxide investigation or service call.
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM
Type of Alarm What You See and Hear
Carbon Monoxide (CO)
Voice: “Warning, evacuate carbon monoxide in [Location,
example: “Hallway”]. Evacuate.” “____ ppm.”
Horn: 4 beeps, pause, 4 beeps, voice LED: Flashes Red
Smoke Voice: “Warning, evacuate smoke in [Location, example: “Hallway”]. Evacuate.”
Horn: 3 beeps, pause, 3 beeps, voice LED: Flashes Red
Alarms have various limitations. See “General
Limitations of smoke/CO alarms” for details.
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing, move
everyone to a source of fresh air. DO NOT deactivate the alarm!
IF THE CO ALARM SOUNDS
Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can kill you.
In other words, when your CO alarm sounds, you must not ignore it!
IF THE CO ALARM SIGNAL SOUNDS:
1. Press the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the number of your local emergency service here:
____________________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window. Do a head count to check that all persons are
accounted for. Do not re-enter the premises, or move away from the open door or window until the emergency services
responder has arrived, the premises have been aired out, and your CO alarm remains in its normal condition.
4. After following steps 1-3, if your CO alarm reactivates within a 24-hour period, repeat steps 1-3 and call a qualified appliance technician to investigate
for sources of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identified during this
inspection have the equipment serviced immediately. Note any combustion equipment not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more information about CO safety and this equipment. Make sure that motor vehicles are not,
and have not, been operating in an attached garage or adjacent to the residence. Write down the number of a qualified appliance technician here:
____________________________________________________________________
NOTE: A qualified appliance technician is defined as “a person, firm, corporation, or company that either in person or through a
representative, is engaged in and responsible for the installation, testing, servicing, or replacement of heating, ventilation, air conditioning
(HVAC) equipment, combustion appliances and equipment, and/or gas fireplaces or other decorative combustion equipment.”
AFTER AN ALARM
After the emergency responders arrive, the premises aired out, and your CO alarm remains in its normal
condition, you can check what the highest carbon monoxide level sensed was:
Action: Alarm Will Say:
Press & hold test button
“Highest carbon monoxide level was ___ ppm. Please see manual.”
“To clear highest carbon monoxide level,
press and hold test button now.”
Press & hold test button, if you would like to clear
the highest level sensed. If you would like to keep the
highest level in memory, do not press anything.
“Highest carbon monoxide level cleared.” alarm will say nothing.
