This user’s manual contains important information about your Combination Carbon Monoxide & Smoke Alarm’s operation. If
you are installing this Alarm for use by others, you must leave
this manual—or a copy of it—with the end user.

INTRODUCTION
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.
___________________________________________________________________________________________________________________________

FIRE SAFETY TIPS

Follow safety rules and prevent hazardous situations: 1) Use smoking materials properly. Never smoke in bed. 2) Keep matches or lighters away from children; 3)
Store flammable materials in proper containers; 4) Keep electrical appliances in good condition and don’t overload electrical circuits; 5) Keep stoves, barbecue grills,
fireplaces and chimneys grease- and debris-free; 6) Never leave anything cooking on the stove unattended; 7) Keep portable heaters and open flames, like candles,
away from flammable materials; 8) Don’t let rubbish accumulate. Keep alarms clean, and test them weekly. Replace alarms immediately if they are not working
properly. Smoke Alarms that do not work cannot alert you to a fire. Keep at least one working fire extinguisher on every floor, and an additional one in the kitchen.
Have fire escape ladders or other reliable means of escape from an upper floor in case stairs are blocked.

INSTALLATION
WHERE TO INSTALL THIS ALARM

MINIMUM COVERAGE FOR SMOKE ALARMS, as recommended by the National Fire Protection Association (NFPA), is one Smoke Alarm on every floor, in every
sleeping area, and in every bedroom (See “Regulatory Information For Smoke Alarms” for details on the NFPA recommendations). For CO Alarms, the National
Fire Protection Association (NFPA) recommends that a CO Alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the
bedrooms. For added protection, install additional CO Alarms in each separate bedroom, and on every level of your home. NOTE: For added protection, install an
additional Smoke/CO Alarm at least 15 feet (4.6 meters) away from the furnace or fuel burning heat source where possible. In smaller homes or in manufactured
homes where this distance cannot be maintained, install the Alarm as far away as possible from the furnace or other fuel burning source. Installing the Alarm closer
than 15 feet (4.6 meters) will not harm the Alarm, but may increase the frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly or completely closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. If a hall is more than 40 feet (12 meters) long, install a unit at
each end.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and storage areas, where temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).

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/CO Alarm. To avoid dead air spaces, follow installation recommendations below.
On ceilings, install Smoke/CO Alarms as close to the center of the ceiling as possible. If this is not possible, install the Smoke/CO Alarm at least 4 inches (102 mm)
from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke/CO Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from
the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install first Smoke/CO Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional
Smoke/CO Alarms may be required depending on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for details on requirements for sloped or peaked
ceilings.
___________________________________________________________________________________________________________________________

HOW TO INSTALL THIS ALARM
This combination Smoke/CO Alarm was designed to be mounted on the ceiling or wall. It is not a tabletop device. You must install this device on the ceiling or
wall as outlined below. Read “Where To Install This Alarm” before starting.
• Do not connect this unit to any other alarm or auxiliary device. It is a single-station unit that cannot be linked to other devices. Connecting anything
else to this unit may prevent it from working properly.
• Do not install this unit over an electrical junction box. Air currents around junction boxes can prevent smoke from reaching the sensing chamber and
prevent the unit from alarming. Only AC powered units are intended for installation over junction boxes.

RECOMMENDED PLACEMENT

• When installing on the wall, the top edge of Smoke
Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to
the center as possible.
• In either case, install at least 4 inches (102 mm) from
where the wall and ceiling meet. See “Avoiding Dead Air

“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT remove the batteries!

IF 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.”

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.
Alarms have various limitations.
If a door is cool, open it slowly. Don’t open a hot door. Keep doors and windows closed, unless you must escape
See “General Limitations of Smoke/

CO Alarms” for details.
• 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 remove the batteries to quiet an unwanted alarm. Removing the batteries disables the alarm and removes your protection.
The Silence Feature is intended to temporarily silence the horn while you identify and correct the problem. Do not use the Silence Feature in emergency situations. It
will not correct a CO problem or extinguish a fire. The Silence Feature can temporarily quiet an unwanted alarm for several minutes. Press 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” for up to 8 hours. Press the Test/Silence button on the alarm cover. Once the low battery
warning “chirp” silence feature is activated, the unit continues to flash the Green light once a minute for 8 hours. After 8 hours, the low battery “chirp” will resume.
Replace the batteries as soon as possible; this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go into Test Mode and the low battery warning will resume (LED flashes and unit
sounds “chirp” once a minute).

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!
___________________________________________________________________________________________________________________________

FINDING THE SOURCE OF CO AFTER AN ALARM

Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after an alarm. These are a few of the factors that can make it
difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK Brands, Inc. shall not be obligated to pay for any
carbon monoxide investigation or service call.
___________________________________________________________________________________________________________________________

POTENTIAL SOURCES OF CO IN THE HOME

Fuel-burning appliances like: portable heater, gas or wood burning fireplace, gas kitchen range or cooktop, gas clothes dryer.
Damaged or insufficient venting: corroded or disconnected water heater vent pipe, leaking chimney pipe or flue, or cracked heat exchanger, blocked or clogged
chimney opening.
Improper use of appliance/device: operating a barbecue grill or vehicle in an enclosed area (like a garage or screened porch).
Transient CO Problems: “transient” or on-again-off-again CO problems can be caused by outdoor conditions and other special circumstances.

USING THE SILENCE FEATURES

When the Smoke Alarm is Silenced

When the CO Alarm is Silenced

The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds. Heavy air in the vent pipes (cold/humid air with
extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
• Several appliances running at the same time competing for limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace).
3. Temperature inversions, which can trap exhaust close to the ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your home. Since these conditions can
come and go, they are also hard to recreate during a CO investigation.
___________________________________________________________________________________________________________________________

HOW CAN I PROTECT MY FAMILY FROM CO POISONING?

A CO Alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before Carbon Monoxide levels become threatening for average, healthy
adults. A CO Alarm is not a substitute for proper maintenance of home appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks, or
separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
• Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and HVAC companies offer appliance inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances. Check appliances for excessive rust and scaling. Also check the flame on the burner and pilot lights.
The flame should be blue. A yellow flame means fuel is not being burned completely and CO may be present. Keep the blower door on the furnace closed. Use vents
or fans when they are available on all fuel-burning appliances. Make sure appliances are vented to the outside. Do not grill or barbecue indoors, or in garages or on
screen porches.
• Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window or a door. Opening windows and doors can significantly
decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your
CO Alarm sounds.

REGULATORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCATIONS FOR SMOKE ALARMS

INSTALLING SMOKE ALARMS IN SINGLE-FAMILY
RESIDENCES The National Fire Protection Association (NFPA),
recommends one Smoke Alarm on every floor, in every sleeping
area, and in every bedroom. In new construction, the Smoke
Alarms must be AC powered and interconnected. See “Agency
Placement Recommendations” for details. For additional
coverage, it is recommended that you install a Smoke Alarm in
all rooms, halls, storage areas, finished attics, and basements,
where temperatures normally remain between 40˚ F (4.4˚ C) and
100˚ F (37.8˚ C). Make sure no door or other obstruction could
keep smoke from reaching the Smoke Alarms.
MORE SPECIFICALLY, INSTALL SMOKE ALARMS:
• On every level of your home, including finished attics and
basements.
• Inside every bedroom, especially if people sleep with 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 floor 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.

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.

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 Smoke Alarm to install, refer the National
Fire Protection Association (NFPA) Standard 72 (National Fire Alarm and Signaling
Code) and NFPA 101 (Life Safety Code). National Fire Protection Association, One
Batterymarch Park, Quincy, MA 02269-9101. Local building codes may also require
specific units in new construction or in different areas of the home.

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).

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.
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that of the receiver.
• Consult the dealer or an experienced radio or TV technician for help.
Warning: Changes or modifications to the product, not expressly approved by First Alert / BRK Brands, Inc., could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.

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.

This Smoke/CO Alarm may not sense smoke or CO on another level of the home.
Example: This alarm device, installed on the second floor, may not sense smoke or
CO in the basement. For this reason, one alarm device may not give adequate early
warning. Recommended minimum protection is one alarm device in every sleeping
area, every bedroom, and on every level of your home. Some experts recommend
battery powered Smoke and CO Alarms be used in conjunction with interconnected AC
powered Smoke Alarms. For details, see “About Smoke Alarms” for details.

Smoke/CO Alarms 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.

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 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.

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.

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.
