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.

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.

This unit should receive continuous electrical power. (The battery

is meant for emergency back-up only). Choose an outlet where it

cannot be accidentally unplugged or switched off by children. Keep

small children away from the unit. Teach them not to play with it or

unplug it. Explain what the alarms mean.

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 extremely humid areas. This Alarm should be at least 10 feet

(3 meters) from a bath or shower, sauna, humidifier, vaporizer, dish-

washer, laundry room, utility room or other source of high humidity.

• 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.

• In outlets covered by curtains or other obstruction.

• This CO Alarm is designed for use inside a single-family home

or apartment. It is not meant to be used in common lobbies,

hallways, or basements of multi-family buildings unless working

CO Alarms are also installed in each family living unit.

CO Alarms in common areas may not be heard from inside

individual family living units.

• This CO Alarm alone is not a suitable substitute for complete

detection systems in places which house many people, like hotels

or dormitories, unless a CO Alarm is also placed in each unit.

• DO NOT use this CO Alarm in warehouses, industrial or com-

mercial buildings, special-purpose non-residential buildings, or

airplanes. This CO Alarm is specifically designed for residential

use, and may not provide adequate protection in non-residential

applications.

• THIS IS NOT A SMOKE ALARM! This CO Alarm is designed to

detect carbon monoxide from ANY source of combustion. It is

NOT designed to detect smoke, fire, or any other gas.

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

•This CO Alarm will only indicate the presence of carbon

monoxide gas at the sensor. Carbon monoxide gas may be

present in other areas.

• The Silence Feature is for your convenience only and will not

correct a CO problem. Always check your home for a potential

problem after any alarm. Failure to do so can result in injury or

death.

• This CO Alarm should receive continuous 120VAC, 60 Hz, pure

sine wave electrical power. (The battery is meant for emergency

back-up only). Do not use in an extension cord or outlet

controlled by a dimmer or switch. In order for the emergency

battery back-up to work, a working (fresh) battery must be

properly installed.

• NEVER ignore your Carbon Monoxide Alarm if it alarms. Refer

to “If Your CO Alarm Sounds” for more information. Failure to

do so can result in injury or death.

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

test correctly, have it replaced immediately! If the CO 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

HOW YOUR CO ALARM WORKS

GENERAL INFORMATION

Leave your CO Alarm plugged in year-round. CO problems can

occur any time during the year, and this Alarm can only alert you if

it is plugged in and receiving power.

This CO Alarm is intended for use in a standard, unswitched 120V AC

wall outlet. It is not intended for use in extension cords, power strips, or

outlets controlled by a switch or dimmer. These may not provide contin-

uous power to the unit. When fully powered, the unit samples the air

and takes a new reading about every second. A microchip inside the

unit stores each reading, and remembers the levels of CO it has been

exposed to over time. The Alarm sounds when it has been exposed to

a “critical” level of CO (measured in parts per million or “ppm”) within

a specified time (measured in minutes). This CO Alarm features a

permanently installed sensor, an indicator light, and an 85dB alarm horn.

It also has a Silence Feature to temporarily quiet the alarm horn.

MALFUNCTION WARNING

This unit performs self-diagnostic tests. If the Alarm malfunctions, it

should be replaced immediately. See "IF THE CO ALARM IS NOT

OPERATING PROPERLY" for more information.

HOW TO INSTALL YOUR CO ALARM

Read “Where To Install CO Alarms” before starting.

Before you start installation, find the pair of self-adhesive labels

included with this CO Alarm. On each label write in the phone number

of your emergency responder (like 911) and a qualified appliance tech-

nician. Place one label near the CO Alarm, and the other label in the

“fresh air” location you plan to go if the alarm sounds.

IF YOUR 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 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:

____________________________________________________________

Alarms have various limitations. See "General Limitations of CO

Alarms" for details.

USING THE SILENCE FEATURES

• The Silence Feature is for your convenience only and will

not correct a CO problem. Always check your home for a

potential problem after any alarm. Failure to do so can result

in injury or death.

• NEVER remove the batteries from your CO Alarm to silence

the horn. Use the silence feature. Removing the batteries

removes your protection! See “If Your CO Alarm Sounds” for

details on responding to an alarm.

The Silence Feature is intended to temporarily silence your CO Alarm’s

alarm horn while you correct the problem—it will not correct a CO prob-

lem. While the alarm is silenced it will continue to monitor the air for CO.

When CO reaches alarm levels the alarm will sound— repeating horn

pattern: 4 beeps, a pause, 4 beeps, etc. Press and hold the Test/Silence

button until the horn is silent. The initial Silence cycle will last approxi-

mately 4 minutes.

NOTE: After initial 4-minute Silence cycle, the CO Alarm re-evaluates

present CO levels and responds accordingly. If CO levels remain poten-

tially dangerous—or start rising higher—the horn will start sounding again.

While the detector is silenced:

“ALARM-MOVE TO FRESH AIR”

If you hear the alarm horn and the red light is flashing, move

everyone to a source of fresh air. DO NOT unplug the CO Alarm!

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.

HOW CAN I PROTECT MY FAMILY?

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 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. CO levels 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.

TESTING AND MAINTENANCE

WEEKLY TESTING

Press the Test/Silence button on the Alarm cover until alarm sounds.

During testing, you will hear a loud alarm sequence – 4 beeps, pause,

4 beeps, pause.

The alarm sequence should last 5-6 seconds. If it does not alarm, make

sure the unit is fully plugged into an unswitched outlet. If the unit still

does not alarm, replace it immediately.

• 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.

• 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.

• NEVER use vehicle exhaust! Exhaust may cause permanent

damage and voids your warranty.

REGULAR MAINTENANCE

To keep the CO Alarm working properly:

• Test it every week as described in “Weekly Testing.”

• Vacuum the CO Alarm cover at least once a month, using the soft

brush attachment. Never use water, cleaners, or solvents, since

they may damage the unit. Test the Alarm again after vacuuming.

• Replace the battery immediately when you hear the “Low Battery

Warning”.

The Low (or Missing) Battery Warning: The horn will “chirp” once a

minute.

REPLACING THE BATTERY

Choosing a Replacement Battery:

This CO Alarm requires one standard 9 volt battery. The following

batteries are acceptable as replacements: Duracell MN1604, Energizer

522, and Ultralife U9VL-J-P. These replacement batteries are commonly

available at 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.

To Replace The Battery:

1. Open the battery compartment.

2. Use the thumb guide to remove the old battery.

3. Insert the new battery, making sure it snaps completely into the

battery compartment and cannot be shaken loose.

4. Close the battery compartment, then test the battery back-up by

pressing the Test/Silence button.

5. Plug the CO Alarm back into the outlet.

•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.

• DO NOT spray cleaning chemicals or insect sprays directly on

or near the CO Alarm. DO NOT paint over the CO Alarm. Doing

so may cause permanent damage.

• Household cleaners, aerosol chemicals and other contaminants

can affect the sensor. When using any of these materials near the

CO Alarm, make sure the room is well ventilated.

• If your home is being fumigated, unplug the unit temporarily and

put it where it will not be exposed to chemicals or fumes. When

fumigation is complete and all traces of fumes clear, plug the unit

back in and retest it.

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 CO Alarm requires a con-

tinuous supply of AC power. Plug into an unswitched 120V AC outlet only.

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 CO 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.

TROUBLESHOOTING GUIDE

PROBLEM... THIS MEANS... YOU SHOULD...

Red light is OFF. Unit will not alarm when you

press the Test/Silence button. CO Alarm may not be plugged all the way in,

is not receiving power, and the battery is missing,

dead, or not properly installed.

Gently push unit all the way into outlet. Make

sure it is not plugged into an outlet controlled

by a switch.

The horn “chirps” once every minute. Low battery warning. Install 1 new 9 volt battery*.

The light flashes (RED) and the horn sounds 3

“chirps” every minute. MALFUNCTION SIGNAL. CO Alarm needs to be

replaced. Make sure unit is plugged in securely.

CO Alarms under warranty should be returned to

manufacturer for replacement. See “Limited

Warranty” for details.

CO Alarm goes back into alarm 4 minutes after

you press the Test/Silence button. CO levels indicate a potentially dangerous

situation.

IF YOU ARE FEELING SYMPTOMS OF CO

POISONING, EVACUATE your home and call 911 or

the Fire Department. If not, press the Test/Silence

button again and keep ventilating your

home.

CO Alarm sounds frequently even though no high

levels of CO are revealed in an investigation. The CO Alarm may be improperly located.

Refer to “Where to Install CO Alarms.” Relocate your Alarm. If frequent alarms continue,

have home rechecked for potential CO problems.

You may be experiencing an intermittent CO

problem.

The light flashes (RED) and the horn sounds 5

“chirps” every minute. END OF LIFE SIGNAL. CO Alarm needs to be

replaced. Immediately replace the CO Alarm.

If you have any questions that cannot be answered by reading this manual, call Consumer Affairs at 1-800-323-9005.

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!

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

POWER/ALARM LIGHT: The LED flashes with the same pattern as

the horn.

WHAT YOU SEE AND HEAR UNDER DIFFERENT CONDITIONS

DURING A POWER FAILURE (IN BATTERY BACK-UP):

HORN: Silent

POWER/ALARM LIGHT: Flashes once a minute.

WHEN THE ELECTRICITY COMES BACK ON AFTER A POWER FAILURE:

HORN: Silent

POWER/ALARM LIGHT: Shines continuously.

IF BATTERY BECOMES LOW OR IS MISSING:

HORN: Chirps once a minute

POWER/ALARM LIGHT: Shines continuously if AC is present or

flashes coincident with the horn-chirp if AC is not present.

IF THE CO ALARM IS NOT OPERATING PROPERLY (MALFUNCTION

SIGNAL):

HORN: 3 chirps every minute

POWER/ALARM LIGHT: Flashes three times with the horn.

IF THE CO ALARM HAS REACHED ITS END OF LIFE:

HORN: 5 chirps every minute

POWER/ALARM LIGHT: 5 flashes approximately once a minute.

WHAT YOU SEE AND HEAR IF CO IS DETECTED

ALARM LEVELS OF CO ARE DETECTED:

HORN: Sounds loudly - 4 beeps, pause, 4 beeps, pause.

This sequence repeats for as long as the unit is in alarm.

POWER/ALARM LIGHT: The LED flashes with the same pattern as

the horn.

IF YOU SILENCE THE ALARM:

HORN: Silent for about 4 minutes

POWER/ALARM LIGHT: Flashes rapidly

Note: After 4 minutes, if CO levels drop below alarm levels, the unit

will remain silent and return to normal operation.

If CO presence still indicates a potentially dangerous situation, the

horn will sound again.

IF THE CO LEVELS RETURN TO NORMAL:

HORN: Silent

POWER/ALARM LIGHT: Shines continuously

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 discon-

nected 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.

POTENTIAL SOURCES OF CO IN THE HOME

If the CO Alarm...

Is silent for only 4 minutes,

then starts sounding loudly—

4 beeps, pause,

4 beeps, pause

This means...

CO levels are still potentially

dangerous.

If the CO Alarm...

Remains silent after you

pressed the Test/Silence

button

This means...

CO levels are dropping.

*For a list of acceptable replacement batteries, see “Page 4: Regular Maintenance.”

ACTIVATING THE BATTERY BACK-UP

Activate the battery back-up by installing one 9 volt battery.

1. Push and lift the battery door down to open.

“+” and “–” ends of each

battery are aligned properly.

3. Ensure battery is securely snapped into terminals by pushing in

direction of arrow in the diagram.

4. Close the battery door.

5. Push and hold the Test/Silence button on the cover until you hear

an acknowledge “chirp”. The alarm horn will sound 4 beeps, a

pause, then 4 beeps. The ALARM (RED) light will flash. The alarm

sequence should last 5-6 seconds. If it does not alarm, make sure

the battery is correctly installed, and test it again.

The battery is for back-up only and is not intended to power the

Alarm for an extended period of time in the absence of AC.

DIRECT PLUG ALARM INTO AN OUTLET

This Alarm can be plugged directly into a wall outlet located close to

the floor.

1. Choose a standard UNSWITCHED 120V AC outlet.

2. Plug Alarm in.

For your records, please record:

Date Purchased: ___________Where Purchased: ___________________

Date Installed: _____________/_____________Month/Year

Replace alarm 7 years after installation. Please write the date in

the space provided: ____________/___________Month/Year

The alarm will also provide an audible End-of-Life Signal approxi-

mately 7 years after installation to remind you to replace the unit.

The End-of-Life Signal can be silenced for up to 2 days. Do not unplug

the alarm or remove the batteries until you get replacement.

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.

SILENCING THE LOW BATTERY WARNING

Pressing the silence button can stop the low battery “chirp” for up to 8

hours; do not remove the battery or unplug the Alarm, unless changing

the battery. Activation of low battery silence is acknowledged with a

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

the unit continues to flash the red light once a minute for 8 hours. After

8 hours, the low battery “chirp” will resume. Replace the batteries as

soon as possible.

If you cannot silence the low battery warning, replace the

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.

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.

This unit should receive continuous electrical power. (The battery

is meant for emergency back-up only). Choose an outlet where it

cannot be accidentally unplugged or switched off by children. Keep

small children away from the unit. Teach them not to play with it or

unplug it. Explain what the alarms mean.

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 extremely humid areas. This Alarm should be at least 10 feet

(3 meters) from a bath or shower, sauna, humidifier, vaporizer, dish-

washer, laundry room, utility room or other source of high humidity.

• 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.

• In outlets covered by curtains or other obstruction.

• This CO Alarm is designed for use inside a single-family home

or apartment. It is not meant to be used in common lobbies,

hallways, or basements of multi-family buildings unless working

CO Alarms are also installed in each family living unit.

CO Alarms in common areas may not be heard from inside

individual family living units.

• This CO Alarm alone is not a suitable substitute for complete

detection systems in places which house many people, like hotels

or dormitories, unless a CO Alarm is also placed in each unit.

• DO NOT use this CO Alarm in warehouses, industrial or com-

mercial buildings, special-purpose non-residential buildings, or

airplanes. This CO Alarm is specifically designed for residential

use, and may not provide adequate protection in non-residential

applications.
