Battery Replacement
CAUTION! If the battery reminder tab is not held down
in the battery compartment by the battery, the battery
door will not close, the AC Quick-Connect wire harness
will not attach to the alarm, and the alarm will not
attach to the mounting plate.
After changing the battery, reconnect the alarm and
test by using the Test/Reset/Hush
®
button, and check
that the green LED is on.
Replace battery with one of the following approved
brands:
Duracell
MN1604
or
MX1604
Energizer 522
Eveready 1222
Gold Peak 1604A or 1604S
These batteries can be purchased at your local retailer.
WARNING! Use only the batteries specified. Use of
different batteries may have a detrimental effect on the
Smoke/CO alarm. A good safety measure is to replace
the battery at least once a year, or at the same time you
change your clocks for daylight saving time.
Constant exposure to high or low humidity, or
temperature may reduce battery life.
