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.

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
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
• D
angers, Warnings, and Cautions alert you to important
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
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
• T
his Smoke/CO Alarm is approved for use in single-family
residences. It is NOT designed for marine or RV use.
• 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
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.
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”.
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”
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.
• N
EVER 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.

o 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.
• D
o 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.
1. Hold base firmly and twist the mounting bracket clockwise to
separate it from the base.

2. 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.
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.”

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:
3. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
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:
1. Press & Hold Test Button
Alarm Will Say:
“Highest carbon monoxide level
was ___ ppm. Please see manual.”
“To clear highest carbon monoxide
level, press and hold test button
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. 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.
7. Install the batteries (included). Open the battery door. Match the
terminals on the ends of each battery with the terminals on the
unit. Match “+” to “+” and “-” to “-.” Push the batteries in until they
snap securely and cannot be shaken loose. If the batteries are not
snapped in completely, the unit cannot receive battery power.
NOTE: After you install the batteries, the power indicator light may
flash. (If the unit alarms, the light will blink rapidly, and the horn will
repeatedly sound 3 beeps, pause, 3 beeps.)
8. Position the base of the Alarm over the mounting bracket and turn.
Turn the Alarm clockwise until the unit is in place.
2. Press & Hold Test Button, if you
would like to clear the highest
level sensed.
The optional locking feature is designed to prevent unauthorized removal
of the alarm. It is not necessary to activate the lock in single-family
households where unauthorized alarm
removal is not a concern.
Tools you will need: Needle-nose
pliers or utility knife • Standard flathead
Locking Pin
The feature uses a locking pin which is
molded into the mounting bracket. Remove
locking pin by using needle-nose pliers or
a utility knife.
To permanently remove the locking pin, insert a flathead screwdriver
between the locking pin and the lock and pry the pin out of the lock.
1. Using needle-nose pliers, detach the pin from the
mounting bracket.
2. Insert the locking pin through the hold on the
back of the smoke alarm as shown in
the diagram.
3. When you attach the alarm to the
mounting bracket the locking pin’s head
will fit into a notch on the bracket.
“Highest carbon monoxide level
If you would like to keep the
highest level in memory, do not
press anything.
This silence feature can temporarily quiet the low battery warning
“chirp” for up to 8 hours. You can silence the low battery warning
“chirp” by pressing 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).
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.
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
If the unit alarms get everyone out of the house immediately.
• 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
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. 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.

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.
When the CO Alarm is Silenced
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.
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:
• T

• T
his 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.
In general, install combination Smoke and Carbon Monoxide
• On every level of your home, including finished attics and
• 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).
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.
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.
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.
• T
his 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.
Always use the exact batteries specified by this User’s Manual.
DO NOT use rechargeable batteries. Clean the battery contacts
and also those of the device prior to battery installation. Install
batteries correctly with regard to polarity (+ and -).
Please dispose of or recycle used batteries properly, following
any local regulations. Consult your local waste management
authority or recycling organization to find an electronics
recycling facility in your area. DO NOT DISPOSE OF BATTERIES
Keep battery out of reach of children. In the event a battery is
swallowed, immediately contact your poison control center,
your physician, or the National Battery Ingestion hotline at
202-625-3333 as serious injury may occur.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. All the batteries specified above
are acceptable replacement batteries for this unit. Regardless of the
manufacturer’s suggested battery life, you MUST replace the battery
immediately once the unit starts “chirping” (the “low battery warning”).
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”
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
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:
• W
ind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended
periods between cycles).
• N
egative pressure differential resulting from the use of exhaust
• S
everal appliances running at the same time competing for
limited fresh air.
• V
ent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• O
bstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
3. Temperature inversions, which can trap exhaust close to the
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.
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
To help prevent CO problems and reduce the risk of CO poisoning:
• C
lean 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.
• T
est and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• M
ake 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 fuelburning appliances. Make sure appliances are vented to the
outside. Do not grill or barbecue indoors, or in garages or on
screen porches.
• C
heck for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• C
heck the house or garage on the other side of shared wall.
• K
eep 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.
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
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
* 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
• 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).
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 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.

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
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 to National Fire Protection Association
(NFPA) Standard 72 (National Fire Alarm and Signaling Code) and
NFPA 101 (Life Safety Code). National Fire Protection Association,
One Batterymarch Park, Quincy, MA 02269-9101. Local building codes
may also require specific units in new construction or in different areas
of the home.
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
Smoke/CO Alarms cannot work without power. Battery operated
units cannot work if the batteries are missing, disconnected or dead, if
the wrong type of batteries are used, or if the batteries are not installed
correctly. AC units cannot work if the AC power is cut off for any reason
(open fuse or circuit breaker, failure along a power line or at a power
station, electrical fire that burns the electrical wires, etc.). If you are
concerned about the limitations of battery or AC power, install both
types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor.
Smoke or CO may be present in other areas. Doors or other obstructions
may affect the rate at which CO or smoke reaches the sensors.
If bedroom doors are usually closed at night, we recommend you
install an alarm device (Combination CO and Smoke Alarm, or separate
CO Alarms and Smoke Alarms) in each bedroom and in the hallway
between them.
This Smoke/CO Alarm may not sense smoke or CO on another
level of the home. Example: This alarm device, installed on the second
floor, may not sense smoke or CO in the basement. For this reason,
one alarm device may not give adequate early warning. Recommended
minimum protection is one alarm device in every sleeping area, every
bedroom, and on every level of your home. Some experts recommend
battery powered Smoke and CO Alarms be used in conjunction with
interconnected AC powered Smoke Alarms. For details, see “About
Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness
meets or exceeds current UL standards of 85 dB at 10 feet (3 meters).
However, if the Smoke/CO Alarm is installed outside the bedroom, it
may not wake up a sound sleeper or one who has recently used drugs
or has been drinking alcoholic beverages. This is especially true if the
door is closed or only partly open. Even persons who are awake may
not hear the alarm horn if the sound is blocked by distance or closed
doors. Noise from traffic, stereo, radio, television, air conditioner, or
other appliances may also prevent alert persons from hearing the alarm
horn. This Smoke/CO Alarm is not intended for people who are hearing
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.
Smoke Alarm sounds when no smoke is visible.

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 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 specialpurpose 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
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”.
