SMOKE & CARBON

MONOXIDE ALARM

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.

ELECTRICAL SHOCK HAZARD. Turn off the power to the area
where the Smoke 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.

•

This unit will not alert hearing impaired residents.
It is recommended that you install special units which use
devices like flashing strobe lights to alert hearing impaired
residents.

• Installation of this unit must conform to the electrical codes

in your area; Articles 210 and 300.3 (B) of NFPA 70 (NEC),
NFPA 72, NFPA 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA);
OTFDC (CABO), and any other local or building codes that
may apply. Wiring and installation must be performed by a
licensed electrician. Failure to follow these guidelines may
result in injury or property damage.

•

This unit must be powered by a 24-hour, 120VAC pure sine
wave 60Hz 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.

•

This Alarm must have AC or battery power to operate.
If the AC power fails, battery back-up will allow the alarm
to sound for at least 4 minutes. If AC power fails and the
battery is weak, protection should last for at least 7 days.
If AC power fails and the battery is dead or missing, the
alarm cannot operate.

• 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 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.

HOW TO INSTALL THIS SMOKE/CO ALARM

THE PARTS OF THIS ALARM

This Smoke/CO Alarm 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 (if allowed
by local codes). Read “Where to Install This Alarm” and “Where This Alarm Should Not Be Installed” before you begin installation.
Tools you will need: • Needle-nose pliers or utility knife • Standard flathead screwdriver • Wire strippers.

Make sure the Alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power
from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause
damage to your Alarm.

The basic installation of this Alarm is similar whether you want to
install one Alarm, or interconnect more than one Alarm. If you are
interconnecting more than one Alarm, you MUST read “Special
Requirements For Interconnected Alarms” below before you begin
installation.

ELECTRICAL SHOCK HAZARD. Turn off power to the area where
you will install this unit at the circuit breaker or fuse box before
beginning installation. Failure to turn off the power before installa-
tion may result in serious electrical shock, injury or death.

1. Remove the mounting bracket

from the base, and attach it to
the junction box.

2. Using wire nuts, connect the

power connector to the
household wiring.

3. Plug the power connector into the back of the Alarm.
4. Activate the battery back-up by removing the “Pull to Activate

Battery Back-Up” tab. Or, install battery back-up. Battery back-up
cannot work until you install the battery in the correct position
(Match “+” to “+” and “-” to “-”).

5. Position the base of the Alarm over the mounting bracket, and turn

the Alarm clockwise (right) until the unit is in place. If wall mounted,
adjust unit so words are level.

6. Check all connections.

Improper wiring of the power connector or the wiring leading to
the power connector will cause damage to the Alarm and may
lead to a non-functioning Alarm.

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.
7. Make sure the Alarm is receiving AC power. Under normal

operation, the Green power indicator light will shine continuously.

8. If the Green power indicator light does not light, TURN OFF

POWER TO THE JUNCTION BOX

and recheck all connections.

If all connections are correct and the Green power indicator still
does not light when you restore the power, the unit should be
replaced immediately.

9. Test each Smoke Alarm. Press and hold the Test/Silence button

until the unit alarms. When testing a series of interconnected
units you must test each unit individually. Make sure all units
alarm when each one is tested.

If any unit in the series does not alarm, TURN OFF POWER and
recheck connections. If it does not alarm when you restore
power, replace it immediately.

FOLLOW THESE INSTALLATION STEPS

STAND-ALONE ALARM ONLY:
•

Connect the white wire on the power connector to the neutral
wire in the junction box.

•

Connect the black wire on the power connector to the hot wire
in the junction box.

•

Tuck the orange wire inside the junction box. It is used for
interconnect only.

INTERCONNECTED UNITS ONLY:
Strip off about 1/2” (12 mm) of the plastic coating on the
orange wire on the power connector.
•

Connect the white wire on the power connector to the neutral
wire in the junction box.

•

Connect the black wire on the power connector to the hot wire
in the junction box.

•

Connect the orange wire on the power connector to the
interconnect wire in the junction box. Repeat for each unit you
are interconnecting. Never connect the hot or neutral wires in the
junction box to the orange interconnect wire. Never cross hot
and neutral wires between Alarms.

STAND-ALONE ALARM ONLY:
•

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

INTERCONNECTED UNITS ONLY:
•

If you are interconnecting multiple Alarms, repeat steps
1-5 for each Alarm in the series. When you are finished,
restore power to the junction box.

Special Requirements For Interconnected Alarms

• Failure to meet any of the above requirements could damage

the units and cause them to malfunction, removing your
protection.

• AC and AC/DC Alarms can be interconnected. Under AC

power, all units will alarm when one senses smoke or CO.
When power is interrupted, only the AC/DC units in the
series will continue to send and receive signals. AC powered
Alarms will not operate.

Interconnected units can provide earlier warning of fire than stand-alone
units, especially if a fire starts in a remote area of the dwelling. If any unit
in the series senses smoke, all units will alarm. To determine which Alarm
initiated an alarm, see table:

During an Alarm:

On Initiating Alarm(s) Red LED(s) flashes (flash) rapidly

On All Other Alarms

Red LED is Off

After an Alarm (Latching):

On Initiating Alarm(s)

Red LED(s) On for 2 seconds/Off for 2 seconds

On All Other Alarms

Green LED(s) On, Red LED(s) Off

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˚ 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)
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 Alarm
is placed directly next to a fuel-burning source. Ventilate these
areas as much as possible.

•

Within 5 feet (1.5 meters) of any cooking appliance. In air streams
near kitchens. Air currents can draw cooking smoke into the smoke
sensor and cause unwanted alarms.

•

In extremely humid areas. This Alarm should be at least 10 feet
(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source of high humidity.

•

In direct sunlight.

•

In turbulent air, like near ceiling fans or open windows. Blowing air
may prevent CO or smoke from reaching the sensors.

•

In areas where temperature is colder than 40˚ F (4˚ C) or hotter than
100˚ F (38˚ C). These areas include non-airconditioned crawl
spaces, unfinished attics, uninsulated or poorly insulated ceilings,
porches, and garages.

•

In insect infested areas. Insects can clog the openings to the
sensing 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.

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.

•

If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer
for replacement. See “Limited Warranty” at the end of this
manual.

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:

• The Alarm Voice will say “Testing.” The Horn will sound 3 beeps,

pause, 3 beeps. The Alarm Voice will say “Warning, evacuate
smoke in [Location, example: “Basement”]. Evacuate.” The
Power/Smoke LED flashes Red and the CO LED will be Off.

• Next the Horn will sound 4 beeps, pause, 4 beeps. The Alarm

Voice will say “Warning, evacuate carbon monoxide in [Location,
example: “Basement”]. Evacuate.” The Power/Smoke LED will
be Off and the CO LED flashes Red.

If the unit does not alarm, make sure the batteries are correctly
installed, and test again. If the unit still does not alarm, replace it
immediately.

REGULAR MAINTENANCE

Use only the replacement batteries listed below. The unit may not
operate properly with other batteries. Never use rechargeable
batteries since they may not provide a constant charge.

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. 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.

•

When the battery back-up becomes weak, the Alarm will “chirp”
about once a minute (the low battery warning), and the Voice will
say “Replace battery in [Location, example “Basement”].” Repeated
every 5 hours. This warning should last 7 days, but you should
replace the battery immediately to continue your protection.
The Low Battery Latch feature will be engaged. The Green
Power/Smoke LED will flash On for 2 seconds/Off for 2 seconds.

Choosing a replacement battery:

Your Smoke/CO Alarm requires two “AA” Energizer E91 batteries.
These batteries are available at many local retail stores.

Actual battery service life depends on the Alarm and the environment
in which it is installed. All the batteries specified above are acceptable
replacement batteries for this unit. Regardless of the manufacturer’s
suggested battery life, you MUST replace the battery immediately
once the unit starts “chirping” (the “low battery warning”).

To replace the batteries (without removing Alarm from the ceiling
or wall):

1. Open the battery compartment.

2. Press tabs A and B as shown in the

diagram and remove each battery.

3. Insert the new batteries, making sure

they snap completely into the battery
compartment. Match the terminals on
the ends of the batteries with the
terminals on the unit.

4. Close the battery compartment, and

then test the unit by pressing the
Test/Silence button.
