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 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 level, 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 level 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:

Smoke Alarm

One on every level and

in every bedroom

Carbon Monoxide Alarm

One on every level and

in every bedroom

Fire Extinguisher

One on every level, plus

kitchen and garage

HALLWAY BEDROOMBEDROOM

GARAGE

LIVING ROOM KITCHEN

BASEMENT

RECOMMENDED PLACEMENT (CONTINUED)...

• 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.

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 alarm. To avoid dead air spaces, follow installation recommendations below.

On ceilings, install smoke alarms as close to the center of the ceiling as possible. If this is not possible,

install the smoke 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 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 the first smoke alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally. Additional smoke

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.

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 100 feet (30 meters) inside of a home. Some features

of a home, such as the number of levels, 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 potential

fires with all other First Alert

WIRELESS INTERCONNECT smoke/CO alarms.

Changes or modifications not expressly approved by BRK Brands, Inc. could void the user’s authority to operate the equipment.

ADDING AND LINKING ADDITIONAL WIRELESS INTERCONNECT ALARMS

NOTE: Steps 1 through 3 need to be completed within two minutes. If more than two minutes pass, the Green

power LED will stop blinking. Simply open the battery drawer of the second alarm and repeat steps 1 through 3.

1. Insert the batteries into the battery drawer of the next alarm . DO NOT CLOSE THE DRAWER.

2. Press and hold the test button and then close the battery drawer.

3. Once you hear the unit chirp, release the test button. The Green power LED will start to blink indicating the WIRELESS

INTERCONNECT alarm is waiting for program data from one of the other setup WIRELESS INTERCONNECT alarms.

ADDING AND LINKING ADDITIONAL WIRELESS INTERCONNECT ALARMS (CONTINUED)...

4. Press and hold the test button on the first alarm, until the second alarm chirps and its Green power LED stops blinking. Then release the test button.

5. If you have purchased the hardwired battery back-up WIRELESS INTERCONNECT alarm, you can now connect

the hardwired alarm 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.

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.

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.

Tools you will need: pencil, drill with 3/16” or 5mm drill bit, Phillips screwdriver, hammer.

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.

7. Test the smoke/CO alarm . See “Weekly Testing” for details.

OPTIONAL LOCKING FEATURE

The locking features are designed to discourage unauthorized removal of the battery 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 smoke alarms have two separate locking features: one to lock the battery compartment, and the other to lock the

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

Tools you will need: •Needle-nose pliers or utility knife, standard flathead screwdriver.

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

Using needle-nose pliers or a utility knife, remove one or both pins from the mounting

bracket, depending on how many locking features you want to use.

To permanently remove either lock, insert a flathead screwdriver between

the locking pin and the lock, and pry the pin out of the lock.

IMPORTANT! PLEASE READ CAREFULLY AND SAVE.

The warnings/limitations card and manual contains important information

about your smoke & carbon monoxide (CO) alarm’s operation. If you are

such as testing the alarm, silencing the alarm, re-testing the alarm when in silence and clearing the Latching features.

Two Silence Features. Temporarily silence low battery chirp for up to eight hours before replacing low battery or silence an unwanted alarm for several minutes.

Two Latching Features. Alarm Latch: Easily identifies initiating alarm even after alarm condition has

subsided. Low Battery Latch: Identifies which unit is in low battery condition.

Perfect Mount System includes a gasketless base for easy installation and a mounting bracket that keeps

the alarm secure over a wide rotation range to allow for perfect alignment.

End of Life Signal. Provides audible confirmation alarm needs to be replaced.

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.

IF YOUR SMOKE/CO ALARM SOUNDS

WHAT TO DO FIRST–IDENTIFY THE TYPE OF ALARM

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

Alarms have various limitations. See “General

Limitations of smoke/CO alarms” for details.

IF THE CO ALARM SOUNDS

“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!

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. 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.”

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: Alarm Will Say:

Press & hold test button

“Highest carbon monoxide level was ___ ppm. Please see manual.”

“To clear highest carbon monoxide level,

press and hold test button now.”

Press & hold test button, if you would like to clear

the highest level sensed. If you would like to keep the
