INTRODUCTION
FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters
away from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload
electrical circuits; 5) Keep stoves, barbecue grills, fireplaces and
chimneys grease- and debris-free; 6) Never leave anything cooking
on the stove unattended; 7) Keep portable heaters and open flames,
like candles, away from flammable materials; 8) Don’t let rubbish
accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately
if they are not working properly. Smoke Alarms that do not work cannot
alert you to a fire. Keep at least one working fire extinguisher on every
floor, and an additional one in the kitchen. Have fire escape ladders or
other reliable means of escape from an upper floor in case stairs are
blocked.
BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• This Smoke/CO Alarm is approved for use in single-family
residences. It is NOT designed for marine or RV use.
• This combination Smoke/Carbon Monoxide Alarm has two
separate alarms. The CO Alarm is not designed to detect fire
or any other gas. It will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will only indicate
the presence of smoke that reaches the sensor. The Smoke
Alarm is not designed to sense gas, heat or flames.
• This unit will not operate without battery power. The Smoke/
CO Alarm cannot work until you activate the battery power
pack.
• NEVER ignore any alarm. See “If Your Smoke/CO Alarm
Sounds” for more information on how to respond to an
alarm. Failure to respond can result in injury or death.
• The Silence Features are for your convenience only and will
not correct a problem. See “Using the Silence Features” for
details. Always check your home for a potential problem
after any alarm. Failure to do so can result in injury or death.
• Test this Smoke/CO Alarm once a week. If the Alarm ever fails
to test correctly, have it replaced immediately! If the Alarm is
not working properly, it cannot alert you to a problem.
• This product is intended for use in ordinary indoor locations
of family living units. It is not designed to measure CO
levels in compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards.
Individuals with medical conditions that may make them
more sensitive to carbon monoxide may consider using
warning devices which provide audible and visual signals
for carbon monoxide concentrations under 30 ppm. For
additional information on carbon monoxide and your medical
condition contact your physician.

FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it
difficult to locate the source of CO after an alarm. These are a few of
the factors that can make it difficult to locate sources of CO:
• House well ventilated before the investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may
be difficult to locate the source of CO.
BRK Brands, Inc. shall not be
obligated to pay for any carbon monoxide investigation or service
call.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances like:
portable heater, gas or wood burning
fireplace, gas kitchen range or
cooktop, gas clothes dryer.
Damaged or insufficient venting:
corroded or disconnected water heater
vent pipe, leaking chimney pipe or flue,
or cracked heat exchanger, blocked or
clogged chimney opening.
Improper use of appliance/device:
operating a barbecue grill or vehicle
in an enclosed area (like a garage or
screened porch).
Transient CO Problems:
“transient” or on-again-off-again CO problems
can be caused by outdoor conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel appliances caused by
outdoor conditions such as:
• Wind direction and/or velocity, including high, gusty winds.
Heavy air in the vent pipes (cold/humid air with extended periods
between cycles).
• Negative pressure differential resulting from the use of exhaust
fans.
• Several appliances running at the same time competing for
limited fresh air.
• Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which can
amplify the above situations.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
3. Temperature inversions, which can trap exhaust close to the
ground.
4. Car idling in an open or closed attached garage, or near a home.
These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
recreate during a CO investigation.
HOW CAN I PROTECT MY FAMILY FROM
CO POISONING?
A CO Alarm is an excellent means of protection. It monitors the air
and sounds a loud alarm before Carbon Monoxide levels become
threatening for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home
appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
• Clean chimneys and flues yearly. Keep them free of debris,
leaves, and nests for proper air flow. Also, have a professional
check for rust and corrosion, cracks, or separations. These
conditions can prevent proper air movement and cause
backdrafting. Never “cap” or cover a chimney in any way that
would block air flow.
• Test and maintain all fuel-burning equipment annually. Many
local gas or oil companies and HVAC companies offer appliance
inspections for a nominal fee.
• Make regular visual inspections of all fuel-burning appliances.
Check appliances for excessive rust and scaling. Also check the
flame on the burner and pilot lights. The flame should be blue. A
yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks on
furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
USER’S MANUAL
RECOMMENDED PLACEMENT
• When installing on the wall, the top edge of Smoke Alarms should
be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line.
• When installing on the ceiling, place the alarm as close to the
center as possible.
• In either case, install at least 4 inches (102 mm) from where the
wall and ceiling meet. See “Avoiding Dead Air Spaces” for more
information.
NOTE:
For any location, make sure no door or other obstruction could
keep carbon monoxide or smoke from reaching the Alarm.
Installing Smoke/CO Alarms in Mobile Homes
For minimum security install one Smoke/CO Alarm as close to each
sleeping area as possible. For more security, put one unit in each room.
Many older mobile homes (especially those built before 1978) have little
or no insulation. If your mobile home is not well insulated, or if you are
unsure of the amount of insulation, it is important to install units on
inside walls only.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
Do NOT locate this Smoke/CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics.
Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles
form when something burns. Areas to avoid include poorly ventilated
kitchens, garages, and furnace rooms. Keep units at least 20 feet
(6 meters) from the sources of combustion particles (stove, furnace,
water heater, space heater) if possible. In areas where a 20-foot
(6 meter) distance is not possible – in modular, mobile, or smaller
homes, for example – it is recommended the Smoke Alarm be
placed as far from these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at
a reasonable distance from a fuel-burning source, and thus reduce
“unwanted” alarms. Unwanted alarms can occur if a Smoke/CO
Alarm is placed directly next to a fuel-burning source. Ventilate
these areas as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter
than 100˚ F (37.8˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.
• In insect infested areas. Insects can clog the openings to the
sensing chamber.
• Less than 12 inches (305 mm) away from fluorescent lights.
Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See “Avoiding Dead Air Spaces”.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke/CO
Alarm. To avoid dead air spaces, follow installation recommendations
below.
On ceilings,
install Smoke/CO Alarms as close to the center of the
ceiling as possible. If this is not possible, install the Smoke/CO Alarm
at least 4 inches (102 mm) from the wall or corner.
For wall mounting
(if allowed by building codes), the top edge of
Smoke/CO Alarms should be placed between 4 inches (102 mm) and
12 inches (305 mm) from the wall/ceiling line, below typical “dead air”
spaces.
On a peaked, gabled, or cathedral ceiling,
install first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured
horizontally. Additional Smoke/CO Alarms may be required depending
on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for
details on requirements for sloped or peaked ceilings.
INSTALLATION
WHERE TO INSTALL THIS ALARM
Minimum coverage for Smoke Alarms
, as recommended by the
National Fire Protection Association (NFPA), is one Smoke Alarm
on every floor, in every sleeping area, and in every bedroom (See
“Regulatory Information For Smoke Alarms” for details on the NFPA
recommendations).
For CO Alarms,
the National Fire Protection Association (NFPA)
recommends that a CO Alarm should be centrally located outside of
each separate sleeping area in the immediate vicinity of the bedrooms.
For added protection, install additional CO Alarms in each separate
bedroom, and on every level of your home.
NOTE:
For added protection, install an additional Smoke/CO Alarm at
least 15 feet (4.6 meters) away from the furnace or fuel burning heat
source where possible. In smaller homes or in manufactured homes
where this distance cannot be maintained, install the Alarm as far away
as possible from the furnace or other fuel burning source. Installing the
Alarm closer than 15 feet (4.6 meters) will not harm the Alarm, but may
increase the frequency of unwanted alarms.
In general, install combination Smoke and Carbon Monoxide
Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly
or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 40 feet
(12 meters) long, install a unit at each end.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install Alarms in all rooms, halls, and storage
areas, where temperatures normally remain between 40˚ F and
100˚ F (4.4˚ C and 37.8˚ C).
SUGGESTED AREAS FOR INSTALLING
SMOKE ALARMS, CO ALARMS, AND COMBO UNITS
CO ALARMS
BOTH, OR COMBINATION
SMOKE/CO ALARMS
SMOKE ALARMS
KEY:
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.
In new construction AC and AC/DC smoke alarms MUST
be interconnected to meet NFPA recommendations.
IF THE SMOKE ALARM SOUNDS
RESPONDING TO AN ALARM
• If the unit alarms and you are not testing the unit, it is warning
you of a potentially dangerous situation that requires your
immediate attention. NEVER ignore any alarm. Ignoring the
alarm may result in injury or death.
• Never remove the batteries from a battery operated Smoke/CO
Alarm to stop an unwanted alarm (caused by cooking smoke,
etc.). Removing batteries disables the alarm so it cannot sense
smoke, and removes your protection. Instead open a window
or fan the smoke away from the unit. The alarm will reset
automatically.
• If the unit alarms get everyone out of the house immediately.
WHAT TO DO IN CASE OF FIRE
• Don’t panic; stay calm. Follow your family escape plan.
• Get out of the house as quickly as possible. Don’t stop to get
dressed or collect anything.
• Feel doors with the back of your hand before opening them. If a
door is cool, open it slowly. Don’t open a hot door. Keep doors
and windows closed, unless you must escape through them.
• Cover your nose and mouth with a cloth (preferably damp).
Take short, shallow breaths.
• Meet at your planned meeting place outside your home, and
do a head count to make sure everybody got out safely.
• Call the Fire Department as soon as possible from outside.
Give your address, then your name.
• Never go back inside a burning building for any reason.
• Contact your Fire Department for ideas on making your home
safer.
Alarms have various limitations. See “General Limitations of
Smoke/CO Alarms” for details.
USING THE SILENCE FEATURES
Never deactivate the unit to quiet an unwanted alarm. Deactivating
the alarm disables the unit and removes your protection.
The Silence Feature is intended to temporarily silence the horn while
you identify and correct the problem. Do not use the Silence Feature
in emergency situations. It will not correct a CO problem or extinguish
a fire.
The Silence Feature can temporarily quiet an unwanted alarm for several
minutes. Press the Test/Silence button on the alarm cover for at least
3-5 seconds.
After the Test/Silence button is released, the Red LED blinks during the
silence mode.
When the Smoke Alarm is
Silenced
When the CO Alarm is Silenced
T
he Smoke Alarm will remain
silent for up to 15 minutes, then
return to normal operation.
If the smoke has not cleared–or
continues to increase–the device
will go back into alarm.
The CO Alarm will remain silent
for up to 4 minutes.
After 4 minutes, if CO levels
remain potentially dangerous the
horn will start sounding again.

IF THE CO ALARM SIGNAL SOUNDS:
1. Press the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down
the number of your local emergency service here:
____________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or
window. Do a head count to check that all persons are accounted
for. Do not re-enter the premises, or move away from the open door
or window until the emergency services responder has arrived, the
premises have been aired out, and your CO Alarm remains in its
normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a
24-hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper operation of this
equipment. If problems are identified during this inspection have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician, and consult the manufacturers’
instructions, or contact the manufacturers directly, for more
information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached
garage or adjacent to the residence. Write down the number of a
qualified appliance technician here:
____________________________________________________________
NOTE:
A qualified appliance technician is defined as “a person,
firm, corporation, or company that either in person or through a
representative, is engaged in and responsible for the installation,
testing, servicing, or replacement of heating, ventilation, air conditioning
(HVAC) equipment, combustion appliances and equipment, and/or gas
fireplaces or other decorative combustion equipment.”
“ALARM-MOVE TO FRESH AIR”
If you hear the CO alarm horn and the CO red light is flashing,
move everyone to a source of fresh air.
DO NOT deactivate the alarm!
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM
REGULAR MAINTENANCE
This unit has been designed to be as maintenance free as possible, but
there are a few simple things you must do to keep it working properly.
• Test it at least once a week.
• Clean the Smoke/CO Alarm at least once a month; gently vacuum
the outside of the Smoke/CO Alarm using your household vacuum’s
soft brush attachment. A can of clean compressed air (sold at
computer or office supply stores) may also be used. Follow
manufacturer instructions for use. Test the Smoke/CO Alarm. Never
use water, cleaners or solvents since they may damage the unit.
• If the Smoke/CO Alarm becomes contaminated by excessive dirt,
dust and/or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately.
• Relocate the unit if it sounds frequent unwanted alarms. See
“Where This Alarm Should Not Be Installed” for details.
Actual battery service life depends on the Smoke/CO Alarm and the
environment in which it is installed. Regardless of the manufacturer’s
suggested battery life, you MUST replace the Alarm immediately once
the unit starts “chirping” (the “low battery warning”).
WEEKLY TESTING
• NEVER use an open flame of any kind to test this unit. You
might accidentally damage or set fire to the unit or to your
home. The built-in test switch accurately tests the unit’s
operation as required by Underwriters Laboratories, Inc. (UL).
NEVER use vehicle exhaust! Exhaust may cause permanent
damage and voids your warranty.
• DO NOT stand close to the alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing. When
testing, step away when horn starts sounding.
It is important to test this unit every week to make sure it is working
properly. Using the test button is the recommended way to test this
Smoke/CO Alarm.
You can test this Smoke/CO Alarm:
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
LED
flashes
Red.
• Next the
Horn
will sound 4 beeps, pause, 4 beeps. The
LED
flashes Red.
If the unit does not alarm, make sure it has been activated
correctly, and test again. If the unit still does not alarm, replace
it immediately.

and 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 pho-
to-electric 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.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning
“chirp”. Press the Test/Silence button on the alarm.
Once the low battery warning “chirp” silence feature is activated,
the unit continues to flash the Green light once a minute. After time,
the low battery “chirp” will resume.
Replace the Alarm as soon as
possible; this unit will not operate without battery power!
To deactivate this feature:
Press the Test/Silence button again. The
unit will go into Test Mode and the low battery warning will resume
(LED flashes and unit sounds “chirp” once a minute).
SILENCING THE END OF LIFE SIGNAL
This silence feature can temporarily quiet the End of Life warning
“chirp” for up to 2 days. You can silence the End of Life warning “chirp”
by pressing the Test/Silence button. The horn will chirp, acknowledging
that the End of Life silence feature has been activated.
After approximately 2 days, the End of Life “chirp” will resume.
WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels
do not burn completely, or are exposed to heat (usually fire). Electrical
appliances typically do not produce CO.
These fuels include:
Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly
maintained, are improperly ventilated, or malfunction, CO levels can
rise quickly. CO is a real danger now that homes are more energy
efficient. “Air-tight” homes with added insulation, sealed windows,
and other weatherproofing
can “trap” CO inside.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be
discussed with ALL household members.
Mild Exposure:
Slight headache, nausea, vomiting, fatigue (“flu-like”
symptoms).
Medium Exposure:
Throbbing headache, drowsiness, confusion, fast
heart rate.
Extreme Exposure:
Convulsions, unconsciousness, heart and lung
failure. Exposure to Carbon Monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO
levels are extremely high in a short period of time, or if CO levels reach
a certain minimum over a long period of time. The CO Alarm generally
sounds an alarm before the onset of symptoms in average, healthy
adults. Why is this important? Because you need to be warned of a
potential CO problem while you can still react in time. In many reported
cases of CO exposure, victims may be aware that they are not feeling
well, but become disoriented and can no longer react well enough to
exit the building or get help. Also, young children and pets may be the
first affected. The average healthy adult might not feel any symptoms
when the CO Alarm sounds. However, people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers, or elderly people
can be more quickly and severely affected by CO. If you experience
even mild symptoms of CO poisoning, consult your doctor immediately!
REGULATORY INFORMATION FOR
SMOKE/CO ALARMS
REGULATORY INFORMATION FOR CO ALARMS
WHAT LEVELS OF CO CAUSE AN ALARM?
Underwriters Laboratories Inc. Standard UL2034 requires residential
CO Alarms to sound when exposed to levels of CO and exposure times
as described below. They are measured in parts per million (ppm) of
CO over time (in minutes).
UL2034 Required Alarm Points*:
• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM
BETWEEN 4 and 15 MINUTES.
• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM
BETWEEN 10 and 50 MINUTES.
• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM
BETWEEN
60 and 240 MINUTES.
*
Approximately 10% COHb exposure at levels of 10% to 95% Relative
Humidity (RH).
The unit is designed not to alarm when exposed to a constant level
of 30 ppm for 30 days.
CO Alarms are designed to alarm before there is an immediate life
threat. Since you cannot see or smell CO, never assume it’s not present.
• An exposure to 100 ppm of CO for 20 minutes may not affect
average, healthy adults, but after 4 hours the same level may cause
headaches.
• An exposure to 400 ppm of CO may cause headaches in average,
healthy adults after 35 minutes, but can cause death after 2 hours.
Standards:
Underwriters Laboratories Inc. Single and Multiple Station
carbon monoxide alarms UL2034.
According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:
“Carbon monoxide alarms covered by these requirements are intended
to respond to the presence of carbon monoxide from sources such as,
but not limited to, exhaust from internal-combustion engines, abnormal
operation of fuel-fired appliances, and fireplaces. CO Alarms are intended
to alarm at carbon monoxide levels below those that could cause a loss
of ability to react to the dangers of Carbon Monoxide exposure.” This
CO Alarm monitors the air at the Alarm, and is designed to alarm before
CO levels become life threatening. This allows you precious time to
leave the house and correct the problem. This is only possible if Alarms
are located, installed, and maintained as described in this manual.
Gas Detection at Typical Temperature and Humidity Ranges:

HOW TO INSTALL THIS ALARM
1. Mounting bracket
2. Mounting slots
3. Turn this way to remove
4. Turn this way to attach
1. Test/Silence button
2. Dual Power indicator
light and Alarm indicator:
Green LED provides
visual indication of an
Alarm Memory condition;
Red LED provides visual
indication of an Alarm
and Hush modes
FOLLOW THESE SIMPLE STEPS:
1. Hold the mounting bracket against the ceiling (or wall) so
the two clusters of universal
mounting holes are aligned
approximately at the 9:00 and
3:00 o’clock positions. See
image. Choose one of the three
sets of holes shown, A, B or C
(see image) and trace around one
of the sets. Be sure to choose a
top and bottom slot on opposite
sides so you can rotate the
universal mounting bracket into
position later. This will make it
easier in the future to remove
the mounting bracket without
completely removing the screws.
WARNING! Do not install
this Alarm over an existing
electrical box. Only AC powered units are intended for
installation over electrical boxes.
2. Put the unit where it won’t get covered with dust when you drill
the mounting holes.
3. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
4. Insert the plastic screw anchors (in the plastic bag with screws)
into the holes. Tap the screw anchors gently with a hammer, if
necessary, until they are flush with the ceiling or wall.
5. Install the screws but do not tighten completely. Attach the
mounting bracket by aligning the screws in the open portion of
the universal mounting slots and rotating the bracket into place.
Tighten the screws until they are snug to secure the bracket.
Do not over tighten.
6.
Activating the battery.
Mount alarm to mounting bracket to
activate. Once unit is activated, it cannot be turned off.
NOTE: After you activate the battery, 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.)
Once the Smoke
Alarm is on the bracket, you can rotate the Alarm to adjust the
alignment.
7. Test the Alarm. See “Weekly Testing.”
8. After 10 years of operation or Low Battery
warning, deactivate the Alarm: Insert a tool
below edge where shown and break tab.
Then slide activation switch to deactivate
mode.
NOTE: At end of life or low battery indication (chirp): unit must be
put into deactivation mode to deactivate remaining stored energy
in battery. Unit will no longer function once put into this mode.
Unit will resist re-mounting.
