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 inves-
tigate for sources of CO from fuel-burning equipment and appliances,
and inspect for proper operation of this equipment. If problems are iden-
tified 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.

DO NOT disconnect the battery from the CO Alarm!
BASEMENT
Alarms have various limitations. See "General Limitations of CO Alarms"
for details.
USING THE SILENCE FEATURE
• 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 problem. 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 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 danger-
ous—or start rising higher—the horn will start sounding again.
While the detector is silenced:
If the CO Alarm...
Is silent for only 4 minutes, then
starts sounding loudly—4 beeps,
pause, 4 beeps, pause
If the CO Alarm...
Remains silent after you pressed
the Test/Silence button
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. The horn will chirp, acknowledging that the low
battery silence feature has been activated.
After 8 hours, the low battery "chirp" will resume. Replace the battery 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 battery
immediately.
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.
After approximately 2-3 weeks the End of Life warning cannot be silenced.

TESTING & MAINTENANCE
WEEKLY TESTING
• 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.
• 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.
Push and hold the Test/Silence button on the cover until the LED flashes. 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
fresh batteries are correctly installed, and test it again. If the unit still does not
alarm, replace it immediately.
If the alarm does not test properly:
1. Make sure the battery is installed correctly.
2. Be sure the Alarm is clean and dust-free.
3. Install a fresh 9V battery* and test the Alarm again.
• 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.
• The Test/Silence button is the only proper way to test the CO Alarm.
NEVER use vehicle exhaust! Exhaust may cause permanent damage
and voids your warranty.
*For a list of acceptable replacement batteries, see "Regular Maintenance."
REGULAR MAINTENANCE
To keep the CO Alarm in good working order:
• Test it every week using the Test/Silence button.
Insert Locking Pin
• Vacuum the CO Alarm cover once a month, using the soft brush attach-
ment. 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).
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 one 9V alkaline battery. The following batteries
are acceptable as replacements: Duracell MN1604 or Energizer 522. These
replacement batteries are commonly available at local retail stores.
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.
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 main-
tained, 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.

for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home appliances.
This means...
To help prevent CO problems and reduce the risk of CO poisoning:
CO levels are dropping.
• 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 appli-
ances 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.

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.
Fuel-burning appliances like: portable heater, gas or wood burning fireplace,
gas kitchen range or cooktop, gas clothes dryer.
2. Extended operation of unvented fuel burning devices (range, oven,
fireplace).
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.
4. Car idling in an open or closed attached garage, or near a home.
Improper use of appliance/device: operating a barbecue grill or vehicle in
an enclosed area (like a garage or screened porch). These conditions are dangerous because they can trap exhaust in your
home. Since these conditions can come and go, they are also hard to
