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 inves-
tigate 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:

"ALARM-MOVE TO FRESH AIR"
If you hear the alarm horn and the red light is flash-
ing, move everyone to a source of fresh air. DO NOT
disconnect the battery from the CO Alarm!
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 your pressed
the Test/Silence button
This means...
CO levels are still potentially
dangerous.
This means...
CO levels are dropping.
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 work-
ing 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 you hear a "chirp."
The "chirp"marks the start of the self-test sequence.
• First, the BATTERY (green) and SERVICE (yellow) lights will flash briefly—
this is normal.
• Next, 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
a fresh battery is 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 a fresh battery is installed correctly.
2. Be sure the Alarm is clean and dust-free.
3. Install a fresh 9V alkaline or lithium 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.
• 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 battery when the CO Alarm "chirps" twice a 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 standard 9V alkaline battery. The following alka-
line batteries are acceptable as replacements: Duracell #MN1604 or MX1604;
Eveready "Energizer" 522. You can also use an Ultralife 9 volt lithium battery
#U9VL for longer service life between battery changes. These replacement
batteries are commonly available at local retail stores.
Use only the alkaline or lithium 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 perma-
nent 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.
