Smoke & Carbon
Monoxide Alarm
•
Connect this unit ONLY to other compatible units. See “How
To Install This Smoke/CO Alarm” for details. Do not connect
it to any other type of alarm or auxiliary device. Connecting
anything else to this unit may damage it or prevent it from
operating properly.
The battery compartment resists closing unless a battery is
installed. This warns you the unit will not operate under DC
power without a battery.
Do not stand too close to the unit when the alarm is sounding.
It is loud to wake you in an emergency. Exposure to the horn
at close range may harm your hearing.
Do not paint over the unit. Paint may clog the openings to the
sensing chambers and prevent the unit from operating properly.
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your CO
Alarm sounds, you must not ignore it!
This unit is designed to be mounted on any standard wiring junction
box up to a 4-inch (10 cm) size, on either the ceiling or wall. Read
“Where to Install This Alarm” and “Where This Alarm Should Not Be
Installed ” before you begin installation. If a junction box is not already
in place, install one using standard #12 or #14 gauge copper wire.
ELECTRICAL SHOCK HAZARD. Do not restore power until all
Alarms are completely installed. Restoring power before installation
is complete may result in serious electrical shock, injury or death.

conserve battery power.
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 rec-
ommendations).
• Place one label near the Smoke/CO Alarm, and the other label in
the “fresh air” location you plan to go if the alarm sounds.
UNDERSTANDING THE LIGHT
AND HORN PATTERNS
4. After following steps 1-3, if your Smoke/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 equip-
ment and appliances, and inspect for proper operation of this equip-
ment. 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 informa-
tion 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 representa-
tive, 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.”

requirements, including UL217 and are designed to detect particles
of combustion. Smoke particles of varying number and size are
produced in all fires.
rapid chirps
•
Don’t panic; stay calm. Follow your family escape plan.
•
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.
•
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.
IF YOUR SMOKE/CO ALARM SOUNDS
WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM
Ionization technology is generally more sensitive than photo-
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.
•
•
When installing on the ceiling, place the alarm as close to the
center as possible.
INTERCONNECTED ALARMS ONLY:
Strip off about 1/2” of the plastic coating on the orange
interconnect wire on the power connector.
In either case, install at least 4 inches (102 mm) from where the wall
and ceiling meet. See “Avoiding Dead Air Spaces” for more informa-
tion.
• The same fuse or circuit breaker must power all interconnected units.
• The total length of wire interconnecting the units should be less than
1000 feet (300 meters). The interconnect wire should be Type 18
gauge AWM or larger, rated at least 300V. If an interconnect wire is
not already part of your household wiring, you will need to install
one. This type of wire is commonly available at Hardware and
Electrical Supply stores.
• All wiring must conform to all local electrical codes and Article 760
of the National Electrical Code. Refer to NFPA, Chapter 2 and/or
your local building code for further connection requirements.

Installing Smoke/CO Alarms in Mobile Homes
•
•
Never go back inside a burning building for any reason.
Contact your Fire Department for ideas on making your home safer.
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.

FIRE SAFETY TIPS
4. Position the base of the Smoke/CO Alarm over the mounting bracket
and turn. The Alarm will remain secure over a wide rotation range to
allow for perfect alignment. When wall mounting, this will allow fine-
tuning on the positioning to compensate for out of aligned wall studs
and to keep the wording level. The Alarm can be positioned over the
bracket every 120°. Rotate the Alarm until aligned properly.
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 elec-
trical 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.

“ALARM-MOVE TO FRESH AIR”
•
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/CO 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.

If you are only installing one unit, restore power to the junction box.
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.

Smoke/CO Alarm is installed before removing it from the mounting
bracket. Failure to turn off the power first may result in serious electrical
shock, injury or death.
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.
Always discharge the branch circuit before servicing an AC or
AC/DC Smoke/CO Alarm. First, turn off the AC power at the circuit
breaker or fuse box. Next, remove the battery from Smoke/CO
Alarms with battery back-up. Finally, press and hold the test button.
1. Insert a flathead screwdriver between the mounting bracket pin and
the mounting bracket.
2. Pry the Smoke/CO Alarm away from the bracket by turning both the
screwdriver and the Smoke/CO Alarm counterclockwise (left) at the
same time.
WHEN THE CO ALARM IS SILENCED...
1. Remove the Smoke/CO Alarm from the mounting bracket. If the unit is
locked to the bracket, see the section “To Deactivate the Locking
Feature.”
The CO Alarm will remain silent for 4 minutes. While the Alarm is
silenced, it will continue to monitor the air for CO. After 4 minutes, if CO
levels remain potentially dangerous the horn will start sounding again.
If the unit does not alarm during
testing, DO NOT lock the battery
compartment! Install a new bat-
tery and test again. If it still does
not alarm, replace the Smoke/CO
Alarm immediately.
2. Disconnect the power connector by gently prying it away from the back
of the Smoke/CO Alarm.

This unit must be powered by a 24-hour, 120V AC pure sine
wave 60 Hz circuit. Be sure the circuit cannot be turned off
by a switch, dimmer, or ground fault circuit interrupter. Failure
to connect this unit to a 24-hour circuit may prevent it from
providing constant protection. Unit may be connected to an arc
fault circuit interrupter.
The Silence Feature is intended to temporarily silence the Alarm horn. It
will not correct a CO problem.
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.
3. Insert a flathead screwdriver under the head of
the locking pin, and gently pry it out of the bat-
tery compartment lock. (If you plan to re-lock
the battery compartment, save the locking pin.)
2. Using needle-nose pliers or a utility
knife, detach one locking pin from
the mounting bracket.
LOW BATTERY SILENCE FEATURE
This Silence Feature can temporarily quiet the low battery warning
“chirp” for up to 8 hours if AC power is present. Press the Test/Silence
button on the Alarm cover until you hear the acknowledge “chirp”.
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. The Alarm will continue to
operate as long as AC power is supplied. However, replace the battery as
soon as possible, to maintain protection in event of a power outage.
On a peaked, gabled, or cathedral ceiling, install the first Smoke/CO
Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured hor-
izontally. 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.
4. To re-lock the battery compartment, close the
battery door and reinsert the locking pin in the
lock.

This Smoke/CO Alarm must have AC or battery power to
operate. If AC power fails and the battery is dead or missing,
the alarm cannot operate.
3. Push the locking pin
through the black dot on
the label on the back of
the Smoke/CO Alarm.
Never disconnect the power from an AC powered unit to
stop an unwanted alarm. Doing so will disable the unit and
remove your protection. In the case of a true unwanted
alarm, use the Silence Feature (if equipped), open a window
or fan the smoke away from the unit. The alarm will reset
automatically when it returns to normal operation. Never
remove the batteries from a battery operated unit to stop an
unwanted alarm (caused by cooking smoke, etc.). Instead
open a window or fan the smoke away from the unit. The
alarm will reset automatically.
5. Reconnect the power connector to the back of the Smoke/CO Alarm,
reattach the Smoke/CO Alarm to the mounting bracket, and restore the
power.
