This Co Alarm does not operate without working batteries. Removing
the batteries, or failure to replace them at the end of their service
life, removes your protection.
• High temperatures, low temperatures, high humidity, impact or
dropping can adversely affect LCD displays.
A CO Alarm measures the CO levels in the air. It will alarm if CO levels rise
quickly (if the heat exchanger on your furnace breaks, for example), or if CO
is consistently present (a slow CO leak on a fuel-burning appliance).
This carbon monoxide alarm features a permanently installed sensor, three
colored indicator lights, and an 85 dB alarm horn. It also has a silence feature
to temporarily quiet the alarm horn.

UNDERSTANDING YOUR CO ALARM
INSTALLATION
Lights blink when batteries are first connected.
WHERE TO INSTALL CO ALARMS
DIGITAL DISPLAY: All segments are turned on for a
short time upon initial power. Then the battery level
icon is displayed.
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.
ALARM RECEIVING BATTERY POWER
Green light flashes every minute. Horn is silent.
DIGITAL DISPLAY: Battery icon will show a full or almost
full icon. Battery icon flashes every two seconds.
In standby mode Display will only flash battery icon (will not show 0).
If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm
at BOTH ends of the hallway.
LOW BATTERY WARNING
The light continues to flash (GREEN) and the horn also “chirps” once every
minute. This warning should last for up to 30 days, but you should replace
the batteries as soon as possible.

simulating a CO Alarm condition.
REQUIRED TO MEET NFPA RECOMMENDATIONS
SUGGESTED AREAS FOR INSTALLING ADDITIONAL CO ALARMS
DIGITAL DISPLAY: During the
simulated CO alarm, “CO” is
displayed along with a full alarm
level. Several ppm CO levels are
also displayed and the alarm level
is shown increasing.
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.
CO ALARM
Sensor has detected enough CO to trigger an alarm. Light flashes rapidly
and horn sounds loudly (repeating 4 beeps, pause). See “If Your CO Alarm
Sounds” for details. During an alarm, move everyone to a source of fresh
air. DO NOT move the CO Alarm!
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.
DIGITAL DISPLAY: “CO” alternating with
the ppm number, a full level, and “EVACUATE”.
In a Mobile Home:
• Install CO Alarms on inside walls ONLY. Uninsulated outside walls and
roofs of mobile homes often transfer heat and cold from outdoors.
CO ALARM REQUIRES SERVICE (MALFUNCTION SIGNAL)
The light flashes (GREEN) and the horn sounds
3 “chirps” every minute. CO Alarm needs to be replaced.
DIGITAL DISPLAY: “Err” is displayed.
WHERE CO ALARMS SHOULD NOT BE
INSTALLED
CO ALARM END OF LIFE
The LED flashes Green 5 times in sync with 5 chirps
every minute. CO Alarm needs to be replaced.
DO NOT locate this CO Alarm:
• In garages, kitchens, furnace rooms, or in any extremely dusty, dirty or
greasy areas.
• Closer than 20 feet (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, dishwasher, laundry
room, utility room or other source of high humidity.
• In areas where temperature is colder than 40˚ F (4˚ C) or hotter than 100˚ F
(38˚ C). These areas include unconditioned 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.
DIGITAL DISPLAY: “End” is displayed.
USING THE PEAK CO MEMORY
The CO Memory Feature lets you check the highest level of CO recorded
during an alarm.
To check CO Memory:
1. Press the Peak Level Button until the peak CO
level is displayed.
To clear CO Memory:
1. Automatically resets after 24 hours.
2a. While checking CO memory, press or hold the
Peak Level Button until “CLEAR” is displayed.
b. Press or hold the Peak Level Button until the CO
Memory is cleared.
3. Remove the batteries.
• 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.
NOTE: The highest CO level will be saved for 24 hours. DO NOT clear the
CO Memory reading if you plan to call someone to investigate a CO problem!
Clear the CO Memory reading only after the investigator has checked your
home. If the investigator will not arrive within the 24 hour time period before
the unit automatically resets, be sure to write down the peak level.
• 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 commercial
buildings, special-purpose non-residential buildings, RVs, boats,
or airplanes. This CO Alarm is specifically designed for residential
use, and may not provide adequate protection in non-residential
applications.

HOW TO INSTALL YOUR CO ALARM
USING THE SILENCE FEATURE
Read “Where To Install CO Alarms” before starting.
• 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.
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 technician. Place one
label near the CO Alarm, and the other label in the “fresh air” location you
plan to go if the alarm sounds.
INSTALLING THE AA BATTERIES
1. Flip the battery door down to open.
2. Install both AA batteries
(included) inside the battery
compartment as indicated.
Make sure the “+” and “–”
ends of each battery are
aligned properly.
3. Close the battery door.
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 problem. While
the alarm is silenced it will continue to monitor the air for CO.
To Activate the Silence Feature:
Press and hold the Test/Silence button until the horn is silent.
Once you activate the Silence Feature: the Silence cycle will last
approximately 4 minutes.
NOTE: After initial 4-minute Silence cycle, the CO Alarm re-evaluates present
CO levels and responds accordingly. If CO levels remain potentially dangerous
—or start rising higher—the horn will start sounding again.
TO MOUNT ON THE WALL
While the detector is silenced:
Tools you will need: pencil, drill with 3/16” or 5mm drill bit,
flathead screwdriver, hammer.
1. Choose a location on the wall. Do not install the Alarm closer than 4”
(102 mm) from where the wall meets the ceiling.
2. Hold the mounting guide template against the wall, and make a mark
inside each keyhole where you will drill your mounting hole as shown in
the diagram below.
3. Use a 3/16” (5 mm) drill bit to drill through the marks you made for the
mounting holes.
4. Insert the plastic screw anchors into the mounting holes until they are
flush with the wall. If necessary, tap them gently with a hammer.
5. Insert the screws into the anchors until the screwhead is 1/8 inch (3 mm)
away from the wall.
6. Slide the CO Alarm onto the screws until you feel it click into place.
7. Test the CO Alarm as described in “Weekly Testing.”
If the CO Alarm...
This means...
Is silent for only 4 minutes, then
starts sounding loudly—4 beeps,
pause, 4 beeps, pause
If the CO Alarm...
CO levels are still potentially
dangerous.
This means...
Remains silent after you pressed
the Test/Silence button
CO levels are dropping.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours without having to remove the batteries. You can silence the low
battery warning “chirp” by pressing the Test/Silence button on the alarm
cover.
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.)
If you cannot silence the low battery warning, replace the batteries
immediately.
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:
SILENCING THE END OF LIFE SIGNAL
1. Operate the Test/Silence button.
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
feature has been activated.
After approximately 2 days, the End of Life “chirp” will resume.
After approximately 2-3 weeks the End of Life warning cannot be silenced.
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 reenter 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:

TESTING & MAINTENANCE
WHAT YOU NEED TO KNOW ABOUT CO
WEEKLY TESTING
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.
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.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline, kerosene,
and propane.
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.
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.
You can test this CO Alarm by pressing the Test/Silence button on the Alarm
cover until alarm sounds.
The alarm horn will sound: 4 beeps, a pause, then 4 beeps. The ALARM (RED)
light will flash quickly. The alarm sequence should last 5-6 seconds. If it does
not alarm, make sure fresh batteries are correctly installed, and test it again.
If the unit still does not alarm, replace it immediately.
SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
If the alarm does not test properly:
1. Make sure that fresh batteries are installed correctly.
2. Be sure the Alarm is clean and dust-free.
3. Install fresh AA batteries and test the Alarm again. For a list of acceptable
replacement batteries, see “Regular Maintenance.”
•
•
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.
DO NOT try fixing the Alarm yourself – this will void your warranty!
If the CO Alarm is still not operating properly, and it is still under
warranty, please see "How to Obtain Warranty Service" in the Limited
Warranty. Install a new CO Alarm immediately.
NEVER use vehicle exhaust! Exhaust may cause permanent damage
and voids your warranty.
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.
REGULAR MAINTENANCE
FINDING THE SOURCE OF CO AFTER AN ALARM
To keep the CO Alarm in good working order:
•
Test it every week using the Test/Silence button.
•
Vacuum the CO Alarm cover once a month, using the soft brush attachment. Never use water, cleaners, or solvents, since these may damage
the unit. Test the CO Alarm again after vacuuming.
•
Replace the batteries when the CO Alarm “chirps” about every minute
(the low battery warning).
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.
The low battery warning should last for 30 days, but you should replace the
battery immediately to continue your protection.
Choosing a replacement battery:
This CO Alarm requires two standard AA batteries. The following batteries
are acceptable as replacements: Energizer E91. These replacement batteries
are commonly available at local retail stores.
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.
Use only the replacement batteries listed. The unit may not operate properly
with other batteries. Never use rechargeable batteries since they may not
provide a constant charge.
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.
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.

POTENTIAL SOURCES OF CO IN THE HOME
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).
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.
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.
UNDERWRITERS LABORATORIES INC. UL2034
WHAT LEVELS OF CO CAUSE AN ALARM?
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!
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.
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.
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.
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.
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.
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 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 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 two standard
AA batteries to operate.
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 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.
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.
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 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.
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.
