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 CO Alarm is approved for use in single-family residences.

•

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.

• This 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 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 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.

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 CO Alarm will automatically

communicate both potential fires and carbon monoxide presence with all

other First Alert® WIRELESS INTERCONNECT Smoke/CO Alarms.

InsTallaTIOn

Where TO InsTall 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.

If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm

at BOTH ends of the hallway.

Refer to state and local building codes for additional requirements.

In a Single-level Home:

• Install at least one CO Alarm near or within each separate sleeping area.

• For added protection, install an additional CO Alarm at least 20 feet

(6 meters) away from the furnace or fuel burning heat source.

In a Multi-level Home:

• Install at least one CO Alarm near or within each separate sleeping area.

• For added protection, install at least one CO Alarm on each level of the

home. If you have a basement, install that CO Alarm at the top of the

basement stairs.

• For added protection, install an additional CO Alarm at least 20 feet

(6 meters) away from the furnace or fuel burning heat source.

In Mobile Homes:

• Install CO Alarms on inside walls ONLY. Uninsulated outside walls and

roofs of mobile homes often transfer heat and cold from outdoors.

Where CO alarMs shOUlD nOT Be InsTalleD

Do NOT locate this CO Alarm:

• In garages, kitchens, furnace rooms, or in any extremely dusty, dirty or

greasy areas.

• Closer than 15 feet (4.6 meters) from a furnace or other fuel burning heat

source, or fuel burning appliances like a water heater.

• Within 5 feet (1.5 meters) of any cooking appliance.

• 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 turbulent air, like near ceiling fans, heat vents, air conditioners, fresh air

returns, or open windows. Blowing air may prevent CO from reaching the

sensors.

• In direct sunlight.

lIMITeD WarranTY

REGULATORY INFORMATION FOR CO ALARMS, Continued

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: The CO

Alarm is not formulated to detect CO levels below 30 ppm typically. UL tested

for false alarm resistance to Methane (500 ppm), Butane (300 ppm), Heptane

(500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol (200 ppm) and Carbon

Dioxide (5000 ppm). Values measure gas and vapor concentrations in parts

per million.

Audible Alarm: 85 dB minimum at 10 feet (3 meters).

General lIMITaTIOns Of CO alarMs

This CO Alarm is intended for residential use. It is not intended for use

in industrial applications where Occupational Safety and Health

Administration (OSHA) requirements for carbon monoxide detectors

must be met.

CO alarms may not waken all individuals. If children or others do not readily

waken to the sound of the CO alarm, or if there are infants or family members

with mobility limitations, make sure that someone is assigned to assist them

in the event of an emergency.

CO Alarms will not work without power. This alarm requires a two (2) AA

batteries to operate.

CO Alarms for Solar or Wind Energy users and battery backup power

systems: AC powered CO Alarms should only be operated with true or pure

sine wave inverters. Operating this Alarm with most battery-powered UPS

(uninterruptible power supply) products or square wave or “quasi sine wave”

inverters will damage the Alarm. If you are not sure about your inverter or

UPS type, please consult with the manufacturer to verify.

This CO Alarm will not sense carbon monoxide that does not reach the

sensor. This CO Alarm will only sense CO at the sensor. CO may be present

in other areas. Doors or other obstructions may affect the rate at which CO

reaches the CO Alarm. For this reason, if bedroom doors are usually closed

at night, we recommend you install a CO Alarm in each bedroom and in the

hallway between them.

CO Alarms may not sense CO on another level of the home. For example,

a CO Alarm on the second level, near the bedrooms, may not sense CO in the

basement. For this reason, one CO Alarm may not give adequate warning.

Complete coverage is recommended. Place CO Alarms on each level of the

home.

CO Alarms may not be heard. The alarm horn loudness meets or exceeds

current UL standards of 85 dB at 10 feet (3 meters). However, if the CO Alarm

is installed outside the bedroom, it may not wake up a sound sleeper or one

who has recently used drugs or has been drinking alcoholic beverages. This

is especially true if the door is closed or only partly open. Even persons who

are awake may not hear the alarm horn if the sound is blocked by distance

or closed doors. Noise from traffic, stereo, radio, television, air conditioner, or

other appliances may also prevent alert persons from hearing the alarm horn.

This CO Alarm is not intended for people who are hearing impaired.

CO Alarms are not a substitute for a smoke alarm. Although fire is a

source of carbon monoxide, this CO Alarm does not sense smoke or fire. This

CO Alarm senses CO that may be escaping unnoticed from malfunctioning

furnaces, appliances, or other sources. Early warning of fire requires the

installation of smoke alarms.

CO Alarms are not a substitute for life insurance. Though these CO Alarms

warn against increasing CO levels, BRK Brands, Inc. does not warrant or

imply in any way that they will protect lives from CO poisoning. Homeowners

and renters must still insure their lives.

CO Alarms have a limited life. Although the CO Alarm and all of its parts

have passed many stringent tests and are designed to be as reliable as

possible, any of these parts could fail at any time. Therefore, you must test

your CO Alarm weekly.

CO Alarms are not foolproof. Like all other electronic devices, CO Alarms

have limitations. They can only detect CO that reaches their sensors. They

may not give early warning to rising CO levels if the CO is coming from a

remote part of the home, away from the CO Alarm.

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 of 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.

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!

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.

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.

Some individuals are more sensitive to CO than others, including people

with cardiac or respiratory problems, infants, unborn babies, pregnant

mothers, or elderly people can be more quickly and severely affected by

CO. Members of sensitive populations should consult their doctors for

advice on taking additional precautions.

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.

Alarms have various limitations. See “General Limitations of CO Alarms”

for details.

“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!

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.

The Silence Feature can temporarily quiet an unwanted alarm for several

minutes. You can silence this 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 CO Alarm is Silenced 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.

sIlenCInG The lOW BaTTerY WarnInG

This silence feature can temporarily quiet the low battery warning “chirp” for

up to 8 hours. You can silence the low battery warning “chirp” by pressing

the Test/Silence button on the alarm cover.

Once the low battery warning “chirp” silence feature is activated, the unit

continues to flash the Green light twice a minute for 8 hours. After 8 hours, the

low battery “chirp” will resume. Replace the batteries 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.

laTChInG feaTUres

Alarm Latch is activated after an Alarm is exposed to alarm levels of carbon

monoxide. After CO levels drop below alarm levels, the Red LED will “CO”

begin to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or

“latch” for about 15 minutes, to give you time to determine which unit initiated

the alarm.

Low Battery Latch is activated when the Alarm is in the “low battery

condition”. When this occurs, the LED flashes Green On for 2 seconds/ Power

Off for 2 seconds for about 15 minutes. This feature is designed to help you

identify which Alarm needs to have the battery replaced. Although, the Alarm

will sound the low battery chirp approximately once every minute, sometimes

during the initial stages of “low battery”, the Alarm will chirp in greater intervals

than one minute, sometimes up to several hours, until the battery reaches a

steady low battery level. This innovative feature eliminates the frustration of

waiting for and/or identifying which unit is chirping.

WeeklY TesTInG

• Test the CO Alarm once a week. If the CO Alarm ever fails to test

properly, have it replaced immediately! If the CO Alarm is not

working properly, it cannot alert you to a problem.

• 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 CO

Alarm.

You can test this CO Alarm by pressing and holding the Test/Silence button

on the Alarm cover (typically 3-5 seconds).

During testing, you will see and hear the following sequence:

• The will sound 4 beeps, pause, 4 beeps. The will be Horn Power LED

Off and the flashes Red.CO LED

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

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 CO Alarm at least once a month; gently vacuum the outside

of the 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 CO

Alarm. Never use water, cleaners or solvents since they may damage the

unit.

• If the 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 CO

Alarms Should Not Be Installed” for details.

Choosing a replacement battery:

Your CO Alarm requires two standard AA batteries. The following batteries

are acceptable as replacements: Duracell MN1500. These batteries are

available at many local retail stores.

• Always use the exact batteries specified by this User’s Manual.

DO NOT use rechargeable batteries. Clean the battery contacts and

also those of the device prior to battery installation. Install batteries

correctly with regard to polarity (+ and -).

• Please dispose of or recycle used batteries properly, following any

local regulations. Consult your local waste management authority

or recycling organization to find an electronics recycling facility in

your area. DO NOT DISPOSE OF BATTERIES IN FIRE. BATTERIES

MAY EXPLODE OR LEAK.

• Keep battery out of reach of children. In the event a battery is

swallowed, immediately contact your poison control center, your

physician, or the National Battery Ingestion hotline at 202-625-3333

as serious injury may occur.

Actual battery service life depends on the CO 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.
