INTRODUCTION
FIRE SAFETY TIPS
Follow safety rules and pr
event hazar
dous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters away from
childr
en; 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, fir
eplaces and chimneys gr
ease- and debris-free;
6) Never leave anything cooking on the stove unattended; 7) Keep portable
heaters and open flames, like candles, away fr
om flammable materials;
8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately if they
ar
e 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 fir
e escape ladders or other r
eliable means
of escape fr
om an upper floor in case stairs are blocked.
BASIC SAFETY INFORMATION
Dangers, W
ar
nings, and Cautions aler
t you to impor
tant
operating instr
uctions or to potentially hazar
dous situations.
Pay special attention to these items.
This Smoke/CO Alar
m is appr
oved for use in single-family
residences. It is NOT designed for marine or RV use.
This combination Smoke/Carbon Monoxide Alarm has two separate
alar
ms. The CO Alar
m is not designed to detect fir
e or any other gas.
It will only indicate the pr
esence 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 Alar
m cannot operate without a working battery.
Removing the battery for any reason, or failing to replace the battery
at the end of its 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 Feature is for your convenience only and will not
cor
r
ect a Smoke/CO problem. 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) commer
cial or industrial standar
ds. Individuals with
medical conditions that may make them mor
e sensitive to carbon
monoxide may consider using warning devices which provide
audible and visual signals for carbon monoxide concentrations
under 30 ppm. For additional infor
mation on carbon monoxide
and your medical condition contact your physician.

WEEKL
Y TESTING
NEVER use an open flame of any kind to test this unit. You might
accidentally damage or set fir
e to the unit or to your home.
The built-in test switch accurately tests the unit’s operation as
r
equired by Underwriters Laboratories, Inc. (UL). NEVER use
vehicle exhaust! Exhaust may cause per
manent 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 hor
n starts sounding.
It is impor
tant to test this unit every week to make sure it is working
pr
operly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
Push and hold the Test/Silence button on the cover until
you hear a “chirp.” The “chirp” marks the start of the self-test sequence.
First, the BATTERY (green) and SERVICE (yellow) lights will flash
briefly—this is normal.
• Next, the Smoke Alarm will sound. The smoke symbol will flash, and
you will hear this hor
n pattern: 3 beeps, pause, 3 beeps, pause.
Finally, the CO Alarm will sound. The CO symbol will flash, and you
will hear this horn pattern: 4 beeps, pause, 4 beeps, pause.
If the unit does not alarm, make sur
e the battery is correctly installed, and
test again. If the unit still does not alarm, replace it immediately.
NOTE: During testing, if the yellow service light comes on and the hor
n
“chirps” 3 times, the device should be serviced or r
eplaced. After
testing, if the horn starts to “chirp” every 30 seconds, replace the
battery immediately
.
REGULAR MAINTENANCE
Use only the replacement batteries listed below. The unit may not
operate pr
operly with other batteries. Never use rechargeable batteries
since they may not provide a constant charge.
This unit has been designed to be as maintenance-fr
ee as possible, but there
ar
e a few simple things you must do to keep it working properly:
Test it at least once a week.
Clean the Smoke/CO Alarm at least once a month; gently vacuum the
outside of the Smoke/CO Alarm using your household vacuum’
s soft
brush attachment. T
est 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, r
eplace
the unit immediately.
Relocate the unit if it sounds fr
equent unwanted alarms. See “Where This
Alarm Should Not Be Installed” for details.
Choosing a r
eplacement battery:
Your Smoke/CO Alarm requires one standard 9V battery. The following
batteries ar
e acceptable as replacements: Duracell #MN1604, (Ultra) #MX1604;
Ever
eady (Ener
gizer) #522. You may also use a Lithium battery like the Ultralife
U9VL-J for longer service life between battery changes.
These batteries ar
e
available at many local r
etail stores.
Actual battery service life depends on the Smoke/CO Alarm and the envir
on-
ment in which it is installed. All the batteries specified above ar
e acceptable
replacement batteries for this unit. Regardless of the manufacturer’s suggested
battery life, you MUST r
eplace the battery immediately once the unit starts
“chirping” (the “low battery war
ning”).
WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not
bur
n completely
, or are exposed to heat (usually fire). Electrical appliances
typically do not pr
oduce CO.
These fuels include: W
ood, coal, charcoal, oil, natural gas, gasoline, kerosene,
and pr
opane.
Common appliances ar
e often sources of CO. If they are not properly main-
tained, ar
e impr
operly 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 weatherpr
oofing
can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms ar
e related to CO POISONING and should be discussed
with ALL household members.
Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposur
e:
Thr
obbing headache, drowsiness, confusion, fast heart rate.
Extr
eme Exposur
e:
Convulsions, unconsciousness, heart and lung failur
e.
Exposur
e to Carbon Monoxide can cause brain damage, death.
This CO Alarm measur
es exposur
e to CO over time. It alarms if CO levels
ar
e 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 war
ned of a potential CO problem while
you can still r
eact in time. In many r
eported cases of CO exposur
e, victims
may be awar
e that they are not feeling well, but become disoriented and
can no longer r
eact well enough to exit the building or get help. Also, young
childr
en and pets may be the first af
fected. The average healthy adult might
not feel any symptoms when the CO Alarm sounds. However
, people with
car
diac 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 dif
ficult
to locate the sour
ce of CO after an alarm. These ar
e a few of the factors that
can make it dif
ficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• T
ransient 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 ser
vice call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-bur
ning appliances like:
portable heater
, gas or wood
bur
ning fireplace, gas kitchen
range or cooktop, gas clothes
dryer
.
Damaged or insuf
ficient vent-
ing: corroded or disconnected
water heater vent pipe, leaking
chimney pipe or flue, or cracked
heat exchanger, blocked or
clogged chimney opening.
Impr
oper 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 r
esult in transient CO situations:
1.
Excessive spillage or r
everse 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.
T
emperatur
e 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 ar
e 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 F
AMILY 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.
T
o 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
corr
osion, 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 bur
ned 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 fur
nace 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 decr
ease 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 Alar
m sounds.
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standar
d UL2034 requires residential CO
Alarms to sound when exposed to levels of CO and exposur
e times as
described below. They are measured in parts per million (ppm) of CO over
time (in minutes).
UL2034 Requir
ed 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 ar
e 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.
Accor
ding to Underwriters Laboratories Inc. UL2034, Section 1-1.2: “Carbon
monoxide alarms cover
ed by these r
equir
ements ar
e intended to r
espond to
the pr
esence of carbon monoxide from sources such as, but not limited to,
exhaust fr
om inter

ed
appliances, and fir
eplaces. CO Alarms are intended to alarm at carbon
monoxide levels below those that could cause a loss of ability to r
eact to the
dangers of Carbon Monoxide exposur
e.” This CO Alarm monitors the air at
the Alarm, and is designed to alarm befor
e CO levels become life threatening.
This allows you pr
ecious 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 T
ypical T
emperatur
e and Humidity Ranges:
The CO
Alarm is not formulated to detect CO levels below 30 ppm typically. UL tested
for false alarm r
esistance to Methane (500 ppm), Butane (300 ppm), Heptane
(500 ppm), Ethyl Acetate (200 ppm), Isopr
opyl Alcohol (200 ppm) and Carbon
Dioxide (5000 ppm). V
alues measure gas and vapor concentrations in parts
per million.
Audible Alarm: 85 dB minimum at 10 feet (3 meters).
REGULA
TORY INFORMATION FOR SMOKE ALARMS
RECOMMENDED LOCA
TIONS FOR SMOKE ALARMS
Installing Smoke Alar
ms in Single-Family Residences
The National Fir
e Pr
otection 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 cover
-
age, it is recommended that you install a Smoke Alarm in all rooms, halls,
storage ar
eas, finished attics, and basements, wher
e temperatur
es normally
r
emain between 40˚F (4˚C) and 100˚F (38˚C). Make sure no door or other
obstruction could keep smoke fr
om r
eaching the Smoke Alarms.
Mor
e specifically
, install Smoke Alarms:
On every level of your home, including finished attics and basements.
Inside every bedr
oom, especially if people sleep with the door partly or
completely closed.
In the hall near every sleeping area. If your home has multiple sleeping
ar
eas, install a unit in each. If a hall is more than 40 feet long (12 meters),
install a unit at each end.
At the top of the first-to-second floor stairway, and at the bottom
of the basement stairway
.
Specific requirements for Smoke Alarm installation vary from state to state
and from region to region. Check with your local Fire Department for current
r
equir
ements in your ar
ea.
It is r
ecommended AC or AC/DC units be inter
-
connected for added protection.
INSTALLING SMOKE ALARMS IN MOBILE HOMES
For minimum security install one Smoke Alarm as close to each sleeping area as
possible. For mor
e security
, put one unit in each room. Many older mobile homes
(especially those built befor
e 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
wher
e temperatures normally remain between 40˚F (4˚C) and 100˚F (38˚C).
AGENCY PLACEMENT RECOMMENDATIONS
This equipment should be installed in accordance with NFPA (National Fire
Protection Association) 72 and 101. National Fire Protection Association,
One Batterymar
ch Park, Quincy
, MA 02269-9101.
Additional local building
and r
egulatory codes may apply in your area. Always check compliance
r
equir
ements befor
e beginning any installation.
Standards:
Underwriters Laboratories Inc. Single and Multiple Station Smoke
Alarms 217.
NFPA 72 (National Fire Code)
Smoke Alarms shall be installed in each separate sleeping r
oom, outside each
sleeping ar
ea in the immediate vicinity of the bedr
ooms and on each additional
story of the family living unit, including basements and excluding crawl spaces
and unfinished attics.
In new construction, Alarms shall be so arranged that operation of any one
Alarm shall cause the operation of all Alarms within the dwelling.
Smoke Detection-Are More Smoke Alarms Desirable?
The required number
of Smoke Alarms might not pr
ovide r
eliable early war
ning pr
otection for those
ar
eas separated by a door fr
om the ar
eas pr
otected by the r
equir
ed Smoke
Alarms. For this reason, it is recommended that the householder consider the
use of additional Smoke Alarms for those ar
eas for increased protection. The
additional ar
eas include the basement, bedr
ooms, dining r
oom, 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.
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, fur
nace r
ooms, closets, utility and storage
rooms, basements, and attached garages.

WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms, as recommended by the National
Fir
e Protection Association (NFPA), is one Smoke Alarm on every floor, in
every sleeping ar
ea, and in every bedroom (See “Regulatory Information For
Smoke Alarms” for details on the NFPA recommendations).
For CO Alar
ms,
the National Fir
e Protection Association (NFPA) recommends
that a CO Alarm should be centrally located outside of each separate sleeping
ar
ea in the immediate vicinity of the bedrooms. For added protection, install
additional CO Alarms in each separate bedr
oom, and on every level of your
home.
NOTE: For added pr
otection, install an additional Smoke/CO Alarm at least
20 feet (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 fr
om the furnace
or other fuel burning source. Installing the Alarm closer than 20 feet (6 meters)
will not harm the Alarm, but may increase the frequency of nuisance 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
ar
eas, 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
ar
eas, where temperatures normally remain between 40˚F and 100˚F
(4˚C and 38˚C).
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) fr
om 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 “A
voiding Dead Air Spaces” for more information.
NOTE: For any location, make sur
e no door or other obstruction could keep
carbon monoxide or smoke fr
om reaching the Alarm.
Installing Smoke/CO Alar
ms in Mobile Homes
For minimum security install one Smoke/CO Alarm as close to each sleeping
ar
ea as possible. For more security, put one unit in each room. Many older
mobile homes (especially those built befor
e 1978) have little or no insulation.
If your mobile home is not well insulated, or if you ar
e 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 Alar
m:
In garages, kitchens, furnace rooms, crawl spaces and unfinished attics.
A
void extremely dusty, dirty or greasy areas.
Where combustion particles are produced. Combustion particles form
when something bur
ns. Areas to avoid include poorly ventilated kitchens,
garages, and furnace rooms. Keep units at least 20 feet (6 meters) from
the sour
ces of combustion particles (stove, fur
nace, water heater, space
heater) if possible. In ar
eas where a 20-foot distance is not possible –
in modular, mobile, or smaller homes, for example – it is recommended
the Smoke Alarm be placed as far fr
om these fuel-bur
ning sour
ces as
possible. The placement r
ecommendations are intended to keep these
Alarms at a reasonable distance from a fuel-burning source, and thus
r
educe “unwanted” or “nuisance” alarms. Unwanted alarms can occur if
a Smoke Alarm is placed dir
ectly 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 curr
ents 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)
fr
om a shower
, sauna, humidifier
, vaporizer, dishwasher, laundry room,
utility r
oom, or other source of high humidity.
In direct sunlight.
In turbulent air, like near ceiling fans or open windows. Blowing air may
pr
event CO or smoke fr
om reaching the sensors.
In areas where temperature is colder than 40˚F (4˚C) or hotter than 100˚F
(38˚C). These ar
eas include non-air
conditioned 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 fr
om fluorescent lights. Electrical
“noise” can interfere with the sensor.
In “dead air” spaces. See “Avoiding Dead Air Spaces”.
A
VOIDING DEAD AIR SP
ACES
“Dead air” spaces may pr
event smoke from reaching the Smoke/CO Alarm.
T
o avoid dead air spaces, follow installation r
ecommendations 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) fr
om 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)
fr
om 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, measur
ed horizontally
.
Additional Smoke/CO Alarms may be required depending on the length, angle,
etc. of the ceiling's slope. Refer to NFP
A 72 for details on r
equir
ements for
sloped or peaked ceilings.
HOW TO INST
ALL 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.
Tools you will need: pencil, drill with 3/16” or 5mm drill bit,
flathead screwdriver, hammer.
PREPARE YOUR ALARM LABELS
Find the pair of self-adhesive labels included with this Smoke/CO Alarm.
On each label write in the phone number of your emergency responder
(like 911) and a qualified appliance technician.
Place one label near the Smoke/CO Alarm, and the other label in the
“fr
esh air” location you plan to go if the alarm sounds.
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 replace-
ment of heating, ventilation, air conditioning (HVAC) equipment, combustion
appliances and equipment, and/or gas fireplaces or other decorative com-
bustion equipment.”
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 pr
event 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 sens-
ing 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 counterclockwise (left) to separate
it from the unit.
2. Hold the mounting bracket against the
ceiling (or wall) and use a pencil to mark
the center of each mounting slot.
3. Put the unit where it won’t get covered
with dust when you drill the mounting holes.
4. Using a 3/16-inch (5 mm) drill bit, drill a hole through each pencil mark.
5. Insert the plastic screw anchors into the holes. Tap the screw anchors
gently with a hammer, if necessary, until they are flush with the ceiling or
wall.
Continued...
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 9V battery (included) into the
battery compartment. Match the terminals
on the end of the battery with the termi
-
nals on the unit. Match “+” to “+” and “-”
to “-.” Push the battery in until it snaps in
secur
ely and cannot be shaken loose. If
the battery is not snapped in completely,
the unit cannot r
eceive battery power.
NOTE: The unit may beep briefly when you
install the battery
. This is normal.
The GREEN Light flashes about every
30 seconds when the unit is receiving
battery power.
The batter
y door will not close unless a battery is installed. This warns
you the unit will not operate without a batter
y.
9.
Align the tabs on the base with the tabs on the mounting bracket.
Turn the base until it snaps into place.
10.
If the cover does not line up the way you wanted, adjust it by slowly
r
otating it in either direction.
11. Test the Smoke/CO Alarm. See “Weekly Testing” for details.

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 danger
ous situation that requires your immediate
attention. NEVER ignore any alarm. Ignoring the alarm may result in
injur
y or death.
Never r
emove the batteries fr
om a battery operated Smoke Alarm to
stop an unwanted alarm (caused by cooking smoke, etc.). Removing
batteries disables the alar
m so it cannot sense smoke, and r
emoves
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
dr
essed or collect anything.
Feel doors with the back of your hand befor
e 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.
Alarms have various limitations. See "General Limitations of Smoke/CO
Alarms" for details.
USING THE SILENCE FEATURE
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 corr
ect a CO pr
oblem or extinguish a fir
e.
To use the Silence Feature, press and hold the Test/Silence button on the
cover of the Smoke/CO Alarm for 3 seconds.

All First Aler
t
®
Smoke Alar
ms conform to regulatory requirements,
including UL217 and ar
e designed to detect par
ticles of combustion.
Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally mor
e sensitive than photoelectric
technology at detecting small particles, which tend to be pr
oduced
in gr
eater amounts by flaming fires, which consume combustible
materials rapidly and spr
ead quickly
. Sour
ces of these fir
es may include
paper bur
ning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally mor
e sensitive than ionization
technology at detecting lar
ge particles, which tend to be produced in
greater amounts by smoldering fires, which may smolder for hours
befor
e bursting into flame. Sour
ces of these fir

Where Purchased: _________________________________________
This Smoke/CO Alarm is intended for r
esidential use. It is not intended for use
in industrial applications wher
e Occupational Safety and Health Administration
(OSHA) r
equirements for Carbon Monoxide Alarms must be met. The Smoke
Alarm portion of this device is not intended to alert hearing impair
ed residents.
Special purpose Smoke Alarms should be installed for hearing impair
ed resi-
dents (CO Alarms ar
e not yet available for the hearing impair
ed).
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 grandpar
ents. 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 r
eadily waken to the sound of the Smoke/CO Alarm, or if ther
e are
infants or family members with mobility limitations, make sur
e that someone
is assigned to assist them in fire drill and in the event of an emergency. It is
r
ecommended that you hold a fir
e drill while family members ar
e sleeping in
or
der 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 emer
gency.
Smoke
/CO
Alar
ms cannot work without power
.
Battery operated units cannot
work if the batteries ar
e missing, disconnected or dead, if the wrong type of
batteries ar
e 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 fir
e that bur
ns the electrical
wir
es, 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 pr
esent in other areas. Doors or other obstructions may affect the rate at
which CO or smoke r
eaches the sensors. If bedr
oom doors ar
e usually closed
at night, we r
ecommend you install an alarm device (Combination CO and
Smoke Alarm, or separate CO Alarms and Smoke Alarms) in each bedr
oom
and in the hallway between them.
This Smoke/CO Alar
m 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 r
eason, one alarm device may
not give adequate early war
ning. Recommended minimum protection is one
alarm device in every sleeping ar
ea, every bedroom, and on every level of your
home. Some experts r
ecommend battery powered Smoke and CO Alarms be
used in conjunction with inter
connected AC powered Smoke Alarms. For
details, see “About Smoke Alarms” for details.
Smoke/CO Alar
ms may not be heard.
The alarm hor
n loudness meets or
exceeds curr
ent UL standards of 85 dB at 10 feet (3 meters). However, if
the Smoke/CO Alarm is installed outside the bedr
oom, 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 ar
e awake may not hear the alarm horn if the sound
is blocked by distance or closed doors. Noise fr
om traf
fic, stereo, radio,
television, air conditioner
, or other appliances may also prevent alert persons
fr
om hearing the alarm hor
n. 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, injur
y, or death, since smoke from some fires may not reach
the unit immediately
. Examples of this include persons smoking in bed,
childr
en playing with matches, or fir
es caused by violent explosions
r
esulting from escaping gas.
This Smoke/CO Alar
m is not a substitute for life insurance.
Though this
Smoke/CO Alarm war
ns against increasing CO levels or the presence of
smoke, BRK Brands, Inc. does not warrant or imply in any way that they will
pr
otect lives. Homeowners and renters must still insure their lives.
This Smoke/CO Alar
m has a limited life.
Although this Smoke/CO Alarm
and all of its parts have passed many stringent tests and ar
e designed to be
as r
eliable 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 pr
operly.
This Smoke/CO Alar
m is not foolproof.
Like all other electr
onic devices,
this Smoke/CO Alarm has limitations. It can only detect smoke or CO that
r
eaches the sensors. It may not give early warning of the source of smoke
or CO is in a r
emote part of the home, away from the alarm device.
