IMPORTANT!
The battery backup is designed to provide short-term emergency power to the alarm.
Actual backup time depends on the strength (freshness) of the battery. The battery
backup will not work unless a good battery is properly installed.

CO AND NATURAL GAS ALARM LIMITATIONS
Alarms have limitations. Like any other electronic device, CO and Gas Alarms are not foolproof.
CO and Gas Alarms have a limited operational life. Your CO and Gas Alarm must be tested weekly,
because it could fail to operate at any time. If your CO and Gas Alarm fails to test properly, or if its
self-diagnostic test reveals a malfunction, immediately have the unit replaced (see last page for
warranty information).
because it could fail to operate at any time. If your CO and Gas Alarm fails to test properly, or if its
self-diagnostic test reveals a malfunction, immediately have the unit replaced (see last page for
warranty information).
CO and Gas Alarms can only sense CO which reaches the alarm's sensor. Carbon monoxide may
be present in other areas without reaching the alarm.
be present in other areas without reaching the alarm.
CO or gas could be present on one level of the home and not reach the alarm installed on a different
level. For example, CO or gas in the basement may not reach an alarm on the second level, near
the bedrooms. For this reason, we recommend you provide complete coverage by placing a CO and
Gas Alarm on every level of the home.

Gas Alarm on every level of the home.
This alarm is not a smoke alarm. It will not sense smoke or fire. For early warning of fire, you must
install smoke alarms, even though carbon monoxide can be generated by a fire.

CO and Gas Alarms are not a substitute for property, disability, life or other insurance of any kind.
Appropriate coverage is your responsibility.

POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances, such as;
heaters, gas or wood burning fireplaces, gas kitchen ranges
or cooktops, gas clothes dryers.
Damaged or insufficient venting; such as;
corroded or disconnected water heaters, vent pipes,
leaking chimneys, pipes or flues or cracked heat exchangers, blocked or clogged chimney openings.
Improper use of appliances/devices;
operating a barbeque grill or vehicle in an enclosed area
(such as 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-burning appliances caused by outdoor ambient
conditions, such as:
•
Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/
humid air with extended periods between cycles).
humid air with extended periods between cycles).
•
Negative pressure differential resulting from the use of exhaust fans.
•
Simultaneous operation of several fuel-burning appliances competing for limited internal 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 (ranges, ovens, fireplaces).
3. Temperature inversions which can trap exhaust close to the ground.
4. A car idling in an open or closed attached garage or near a home.
