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

Consumer Affairs: (800) 323-9005 •
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.
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 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˚ C and 38˚ C).
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
Suggested locations are based on
NFPA recommendations (NFPA 72
for Smoke Alarms and NFPA 720 for
Carbon Monoxide Alarms). Always
refer to national and local codes
before beginning any installation.
Test/Silence Button
Battery Compartment
Power/Smoke Alarm LED
CO Alarm LED
In new construction AC and AC/DC smoke alarms MUST
be interconnected to meet NFPA recommendations.
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.
Tools you will need: pencil, drill with 3/16” or 5mm drill bit,
flathead screwdriver, hammer.
• 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.
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.
• 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.
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.
If you want to lock the battery compartment, or lock the Smoke/CO
Alarm to the mounting bracket, please read the “Optional Locking
Features” section.
1. Hold base firmly and twist the mounting bracket counterclockwise (left) to
separate it from the unit.
2. Hold the mounting bracket against the ceiling (or wall) so the vertical
mounting slot is aligned in the 12 o’clock position and trace around the
inside of the mounting slots (vertical and horizontal mounting).
3. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
4. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the oval
outlines you traced.
5. Insert the plastic screw anchors (in the plastic bag with screws) into the
holes. Tap the screw anchors gently with a hammer, if necessary, until
they are flush with the ceiling or wall.
6. Line the mounting bracket up over the plastic screw anchors.
7. Screw the mounting bracket to the ceiling or wall through the mounting
slots using the two screws provided.
8. Before attaching the Alarm to
the bracket, insert the two (2)
AA batteries (included) into the
battery compartment. Match
the terminals on the end of the
battery with the terminals on
the unit. Match “+” to “+” and
“-” to “-.” If the batteries are
not fully inserted, the unit
cannot receive battery power.
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˚ C) or hotter than 100˚F
(38˚ 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
• 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”.
NOTE: The unit may beep briefly when you install the batteries. This is normal.
The GREEN Light flashes about every 60 seconds when the unit is
receiving battery power.
The battery door will resist closing unless batteries are installed. This
warns you the unit will not operate without batteries.
9. Attach the Smoke/CO Alarm to the
mounting bracket. Line up the guides on
the alarm’s base with the guides on the
mounting bracket. When guides are lined
up, turn the base clockwise (right) until it
snaps into place.
“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.
NOTE: Once the Smoke/CO Alarm is
snapped onto the mounting bracket,
you can rotate the Smoke/CO Alarm
to adjust the alignment.
10. Test the Smoke/CO Alarm. See “Weekly Testing” for details.
The optional locking features are designed to discourage unauthorized removal of the batteries or Alarm. It is not necessary to activate the locks in
single-family households where unauthorized battery or Alarm removal is not a concern.
This Smoke/CO Alarm has two separate locking features: one to lock the battery compartment, and the other to lock the Smoke/CO Alarm to the mounting bracket.
You can choose to use either feature independently, or use them both.
Tools you will need: • Needle-nose pliers or utility knife • Standard flathead screwdriver.
Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking features you
use, remove one or both pins from the mounting bracket using needle-nose pliers or a utility knife.
To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the lock, and pry
the pin out of the lock.
Do not lock the battery compartment until you
activate the battery and test the Smoke/CO
1. Remove the Smoke/CO Alarm from the
mounting bracket. If the unit is locked to
the bracket, see the section “To Unlock
the Mounting Bracket.”
1. Install the batteries before attaching the Alarm
to the bracket. Insert the two (2) AA batteries
(included) into the battery compartment. Match
the terminals on the end of the battery with the
terminals on the unit. Match “+” to “+” and “-”
to “-.” If the batteries are not fully inserted, the
unit cannot receive battery power.
2. Insert a flathead screwdriver under the
head of the locking pin, and gently pry it out
of the battery compartment lock. (If you plan
to relock the battery compartment, save the
locking pin.)
2. Push and hold Test/Silence button until the
alarm sounds.
3. To relock the battery compartment, close

3. When you attach the Smoke/CO Alarm to
the mounting bracket, the locking pin’s
head will fit into a notch on the bracket.
• 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.
You can test this Smoke/CO Alarm: Press and hold the Test/Silence button
3-5 seconds until unit starts to alarm.
During testing, you will see and hear the following sequence:
• The Horn will sound 3 beeps, pause, 3 beeps. The Power/Smoke LED
flashes Red and the CO LED will be Off.
• Next the Horn will sound 4 beeps, pause, 4 beeps. The Power/Smoke
LED will be Off and the CO LED flashes Red.
If the unit does not alarm, make sure the batteries are correctly installed,
and test again. If the unit still does not alarm, replace it immediately.
• 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.
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.
Use only the replacement batteries listed below. The unit may not
operate properly with other batteries. Never use rechargeable batteries
since they may not provide a constant charge.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’s soft
brush attachment. A can of clean compressed air (sold at computer or
office supply stores) may also be used. Follow manufacturer instructions
for use. Test the Smoke/CO Alarm. Never use water, cleaners or solvents
since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt, dust
and/or grime, and cannot be cleaned to avoid unwanted alarms, replace
the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See “Where This
Alarm Should Not Be Installed” for details.
Choosing a replacement battery:
Your Smoke/CO Alarm requires two standard AA batteries. The following
batteries are acceptable as replacements: Eveready Energizer E91. These
batteries are available at many local retail stores.
• 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.
Actual battery service life depends on the Smoke/CO Alarm and the environment in which it is installed. All the batteries specified above are acceptable
replacement batteries for this unit. Regardless of the manufacturer’s suggested
battery life, you MUST replace the battery immediately once the unit starts
“chirping” (the “low battery warning”).
To replace the batteries (without removing
Alarm from the ceiling or wall):
1. Open the battery compartment.
2. Press tabs A and B as shown in the diagram
and remove each battery.
3. Insert the new batteries, making sure they
snap completely into the battery compartment.
Match the terminals on the ends of the
batteries with the terminals on the unit.
4. Close the battery compartment, and then test
the unit by pressing the Test/Silence button.
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.
Alarms have various limitations. See "General Limitations of Smoke/CO
Alarms" for details.
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

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
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.
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 twice a minute for 8 hours. After 8 hours, the
low battery “chirp” will resume. Replace the batteries as soon as possible;
this unit will not operate without battery power!
To deactivate this feature: Press the Test/Silence button again. The unit will go
into Test Mode and the low battery warning will resume (LED flashes and unit
sounds “chirp” once a minute).
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!
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!
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the
number of your local emergency service here:
3. Immediately move to fresh air—outdoors or by an open door or window.
Do a head count to check that all persons are accounted for. Do not reenter 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.”
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
• 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.
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.
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!
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.
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.
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.
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).
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.
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˚ C) and 100˚ F (38˚ C). Make sure no
door or other obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly or
completely closed.
• In the hall near every sleeping area. If your home has multiple sleeping
areas, install a unit in each. If a hall is more than 40 feet long (12 meters),
install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom
of the basement stairway.
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 batterypowered 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.
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.
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 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.
This unit alone is not a suitable substitute for complete fire detection
systems in places housing many people—like apartment buildings,
condominiums, hotels, motels, dormitories, hospitals, long-term health
care facilities, nursing homes, day care facilities, or group homes of any
kind—even if they were once single-family homes. 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 unit may be used to
provide additional protection in these facilities.
For minimum security install one Smoke 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. Smoke Alarms should be installed
where temperatures normally remain between 40˚ F (4˚ C) and 100˚ F (38˚ C).
The following information applies to all five types of buildings listed below:
In new construction, most building codes require the use of AC or AC/DC
powered Smoke Alarms only. AC, AC/DC, or DC powered Smoke Alarms can
be used in existing construction as specified by local building codes. Refer to
NFPA 72 (National Fire Alarm 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.”
Standards: Underwriters Laboratories Inc. Single and Multiple Station Smoke
Alarms 217.
NFPA 72 (National Fire Code) Chapter 11
“For your information, the National Fire Protection Association's Standard 72,
reads as follows:”
1. Single-Family Residence: Single family home, townhouse. It is recommended this unit be installed on every level of the home, in every bedroom,
and in each bedroom hallway.
“11.5.1 One- and Two-Family Dwelling Units.”
2. Multi-Family or Mixed Occupant Residence: Apartment building,
condominium. This unit is suitable for use in individual apartments or condos,
provided a primary fire detection system already exists to meet fire detection
requirements in common areas like lobbies, hallways, or porches. Using this
unit in common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
“ Smoke Detection. Where required by applicable laws, codes, or
standards for the specified occupancy, approved single- and multiple-station
Smoke Alarms shall be installed as follows: (1) In all sleeping rooms.
Exception: Smoke Alarms shall not be required in sleeping rooms in existing
one- and two-family dwelling units. (2) Outside of each separate sleeping
area, in immediate vicinity of the sleeping rooms. (3) On each level of the
dwelling unit, including basements. Exception: In existing one- and two family
dwelling units, approved Smoke Alarms powered by batteries are permitted.”
3. Institutions: Hospitals, day care facilities, long-term health care facilities.
This unit is suitable for use in individual patient sleeping/resident rooms,
provided a primary fire detection system already exists to meet fire detection
requirements in common areas like lobbies, hallways, or porches. Using this
unit in common areas may not provide sufficient warning to all residents or
meet local fire protection ordinances/regulations.
“A.11.8.3 Are More Smoke Alarms Desirable? The required number of
Smoke Alarms might not provide reliable early warning protection for those
areas separated by a door from the areas protected by the required Smoke
Alarms. For this reason, it is recommended that the householder consider
the use of additional Smoke Alarms for those areas for increased protection.
The additional areas include the basement, bedrooms, dining room, furnace
room, utility room, and hallways not protected by the required Smoke Alarms.
The installation of Smoke Alarms in kitchens, attics (finished or unfinished),
or garages is not normally recommended, as these locations occasionally
experience conditions that can result in improper operation.”
4. Hotels and Motels: Also boarding houses and dormitories. This unit is
suitable for use inside individual sleeping/resident rooms, provided a primary
fire detection system already exists to meet fire detection requirements in
common areas like lobbies, hallways, or porches. Using this unit in common
areas may not provide sufficient warning to all residents or meet local fire
protection ordinances/regulations.
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.
5. Warehouses/Commercial Buildings: DO NOT use this Smoke/CO Alarm in
warehouses, industrial or commercial buildings, special-purpose non-residential buildings, RVs, boats, or airplanes. This Smoke/CO Alarm is specifically
designed for residential use, and may not provide adequate protection in
non-residential applications.
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.
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.
This Smoke/CO Alarm will not sense smoke or CO that does not reach
the sensors. It will only sense smoke or CO at the sensor. Smoke or CO may
be present in other areas. Doors or other obstructions may affect the rate at
which CO or smoke reaches the sensors. If bedroom doors are usually closed
at night, we recommend you install an alarm device (Combination CO and
Smoke Alarm, or separate CO Alarms and Smoke Alarms) in each bedroom
and in the hallway between them.
This Smoke/CO Alarm may not sense smoke or CO on another level of
the home. Example: This alarm device, installed on the second floor, may not
sense smoke or CO in the basement. For this reason, one alarm device may
not give adequate early warning. Recommended minimum protection is one
alarm device in every sleeping area, every bedroom, and on every level of
your home. Some experts recommend battery powered Smoke and CO
Alarms be used in conjunction with interconnected AC powered Smoke
Alarms. For details, see “About Smoke Alarms” for details.
