MAINTENANCE
BATTERY REPLACEMENT
The CO alarm is powered (backup) by a 9V battery. A fresh battery should last for one
year under normal operating conditions. This alarm has a low battery monitor circuit
which will cause the alarm to sound a short "beep" approximately every 40 seconds,
for a minimum of 7 days, when the battery gets low. Replace the battery when this
condition occurs, by using the QUICK DRAW
TM
pull-out battery drawer for easy
replacement.
Slide the QUICK DRAW
TM
pull-out battery drawer out. While observing polarity, push
the replacement battery into the battery drawer until it is held securely in place. Carefully
close and latch the QUICK DRAW
TM
pull-out battery drawer.
USE ONLY THE FOLLOWING 9 VOLT BATTERIES FOR CO ALARM
REPLACEMENT
Alkaline type: EVEREADY 522; DURACELL MN1604
Lithium type: ULTRALIFE U9VL-J
NOTE: REGULAR TESTING IS RECOMMENDED.
USE ONLY THE BATTERIES SPECIFIED. USE OF DIFFERENT BATTERIES MAY
HAVE A DETRIMENTAL EFFECT ON THE CO ALARM. THE CONSTANT
EXPOSURES TO HIGH OR LOW TEMPERATURES OR HIGH HUMIDITY MAY
REDUCE BATTERY LIFE.
IMPORTANT!
The battery backup is designed to provide short-term emergency power to the CO
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.
