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.

•

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 Smoke/CO Alarm cannot operate without working

batteries. Removing the batteries for any reason, or failing to

replace the batteries at the end of their service life, removes

your protection.

• 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.

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:

• 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.

• 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.

• 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).

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.

HOW TO INSTALL THIS ALARM

For quick installation instructions see the “Quick and Easy Guide to

Programming Your WIRELESS INTERCONNECT Alarm and Using the

Optional Features”.

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,

Phillips screwdriver, hammer.

• Do not install this unit over an electrical junction box. Air

currents around junction boxes can prevent smoke from

reaching the sensing chamber and prevent the unit from

alarming. Only AC powered units are intended for installation

over junction boxes.

If you want to lock the battery compartment, or lock the Smoke/CO

Alarm to the mounting bracket, please read the “Optional Locking

Features” section in the “Quick and Easy Guide to Programming

Your WIRELESS INTERCONNECT Alarm and Using the Optional

Features” attachment before you begin installation.

1. Hold the mounting bracket against the ceiling (or wall) so the vertical

mounting slot is aligned in the 12 o’clock position and trace around

the inside of the mounting slots (vertical and horizontal mounting).

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. Line the mounting bracket up over the plastic screw anchors.

6. Screw the mounting bracket to the ceiling or wall through the

mounting slots using the two screws provided.

7. Attach the Smoke/CO Alarm to the mounting bracket. Line up the

guides on the alarm’s base with the guides

on the mounting bracket. When guides

are lined up, turn the base clockwise

WIRELESS OPERATION

First Alert®WIRELESS INTERCONNECT Technology is the easy, cost-effective

way to provide your family with whole-home safety. All WIRELESS

INTERCONNECT Alarms communicate with each other without wires

or connectors. When one Alarm sounds, they all sound. This provides

your family with an earlier warning of potential danger, and gives you

more time to react.

The communication distance (range) between any two WIRELESS

INTERCONNECT Alarms is typically 50 feet (15 meters) inside of a

home. Some features of a home, such as the number of floors, number/

size of rooms, furniture and types of building materials used may

reduce the range of the Alarms. Examples include: suspended ceilings,

ductwork, large metallic appliances (refrigerators) and metal studs. A

feature of WIRELESS INTERCONNECT Alarms is that they operate as

a mesh network. All Alarms will repeat any alarm signal that is received

to all other WIRELESS INTERCONNECT Alarms. Interference from

structural conditions can be overcome by adding additional Alarms to

route the wireless signal around obstructions.

• The range and proper operation of any wireless device will

vary depending on its surroundings. It is very important that

each Alarm is tested individually before and after installation

to make sure that all Alarms respond properly.

• The WIRELESS INTERCONNECT Alarms are not to be used

outdoors or to transmit between buildings. The Alarms will

not communicate properly under these conditions.

• Metal objects and metallic wallpaper may interfere with

signals from wireless Alarms. Alarms should be tested after

changes to your home such as remodeling, moving furniture,

and with metal doors opened and closed.

Your First Alert®WIRELESS INTERCONNECT Smoke/CO Alarm will

automatically communicate both potential fires and carbon monoxide

presence with all other First Alert®WIRELESS INTERCONNECTSmoke/

CO Alarms.

Changes or modifications not expressly approved by BRK Brands,

Inc. could void the user’s authority to operate the equipment.

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.

TO LOCK THE BATTERY COMPARTMENT

Do not lock the battery compartment until you install the

batteries and test the Alarm.

If the unit does not alarm during

testing, DO NOT lock the battery

compartment! Install new batteries

and test again. If the Alarm still does

not alarm, replace it immediately.

1. Using needle-nose pliers, detach

one locking pin from the mounting

bracket.

2. After batteries are inserted, then

push the locking pin through the

hole near the battery door latch on

the back of the Alarm.

OPTIONAL LOCKING FEATURES

TO LOCK THE MOUNTING BRACKET

1. Using needle-nose pliers, detach

one locking pin from the mounting

bracket.

2. Insert the locking pin through the

hole on the back of the Alarm as

shown in the diagram.

3. When you attach the Alarm to the

mounting bracket, the locking pin’s

head will fit into a notch on the

bracket.

The optional locking features are designed to prevent unauthorized removal of the batteries or alarm. It is not necessary to activate the locks

in single-family households where unauthorized battery or Alarm removal is not a concern.

These Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the

Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.

Tools you will need: • Needle-nose pliers • Standard flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking

features you use, remove one or both pins from the mounting bracket using needle-nose pliers.

To permanently remove either locking pin, insert a flathead screwdriver between the locking pin and the

lock, and pry the pin out of the lock.

TO UNLOCK THE BATTERY COMPARTMENT

1. Remove the Alarm from the

mounting bracket. If the unit is

locked to the bracket, see the

section “To Unlock the Mounting

Bracket.”

2. Insert a flathead screwdriver under

the head of the locking pin, and

gently pry it out of the battery

compartment lock. (If you plan to

relock the battery compartment,

save the locking pin.)

3. To relock the battery compartment,

close the battery door and reinsert

locking pin in lock.

4. Reattach the Alarm to the mounting

bracket.

When replacing the batteries, always

test the Alarm before relocking the battery compartment.

TO UNLOCK THE MOUNTING BRACKET

1. Insert a flathead screwdriver

into the rectangular cut-out on

the mounting bracket nearest to

the locking pin.

2. Pry the Alarm away from the bracket by

pushing up on the screwdriver and

turning the Alarm counterclockwise (left) at

the same time.

IF THE CO ALARM SOUNDS

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!

IF THE CO ALARM SIGNAL SOUNDS:

1. Operate 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:

____________________________________________________________

“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 remove the batteries!

IF YOUR SMOKE/CO ALARM SOUNDS

WHAT TO DO FIRST–IDENTIFY THE TYPE OF

ALARM SIGNAL

Refer to previous section “What You Will See and Hear With This

Alarm”.

AFTER AN ALARM

After the emergency responders arrive, the premises aired out, and

your CO Alarm remains in its normal condition, you can check what

the highest carbon monoxide level sensed was:

Action:

1. Press & Hold Test Button

Alarm Will Say:

“Highest carbon monoxide level

was ___ ppm. Please see manual.”

“To clear highest carbon monoxide

level, press and hold test button

now.”

2. Press & Hold Test Button, if you

would like to clear the highest

level sensed.

If you would like to keep the

highest level in memory, do not

press anything.

“Highest carbon monoxide level

cleared.”

Alarm will say nothing.

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 remove the batteries to quiet an unwanted alarm. Removing

the batteries disables the alarm and removes your protection.

The Silence Feature is intended to temporarily silence the horn while

you identify and correct the problem. Do not use the Silence Feature

in emergency situations. It will not correct a CO problem or extinguish

a fire.

The Silence Feature can temporarily quiet an unwanted alarm for several

minutes. You can silence this Smoke/CO Alarm by pressing the Test/

Silence button on the alarm cover for at least 3-5 seconds.

After the Test/Silence button is released, the Red LED blinks during the

silence mode.

When the Smoke Alarm

is Silenced

When the CO Alarm

is Silenced

The Smoke Alarm will remain

silent for up to 15 minutes, then

return to normal operation.

If the smoke has not cleared–or

continues to increase–the device

will go back into alarm.

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.

STEP BY STEP GUIDE TO PROGRAMMING

THIS ALARM

FOR FIRST TIME AND WHEN CHANGING BATTERIES

Action:

1. Insert batteries (2, AA batteries).

Alarm Will Say:

“Welcome, First Alert Smoke and

by installing the three-wire connector on the ceiling to the Alarm.

6. Repeat steps 1-5 for additional WIRELESS INTERCONNECT

Alarms.

You have now successfully linked your new WIRELESS

INTERCONNECT Alarms.

To add additional Alarms at a later time, follow steps 1 through 5.

ADDING AND LINKING ADDITIONAL WIRELESS

INTERCONNECT ALARMS

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 (4.4˚ 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.
