Low battery
This alarm is equipped with a low battery monitor circuit. If the battery capacity is nearing the point where it
can no longer provide adequate power for all alarm functions, the low battery condition will occur.
See Troubleshooting Guide. The battery must be replaced within 7 days of the first occurrence of the "Low
Battery Warning" to provide continuous alarm protection.
NOTE:
If the battery carrier tamper resist feature has been activated it will need to be deactivated in order to
change the battery. Refer to section "Tamper Resist Features" for instructions.
To replace or install the battery press on the battery carrier and then release to allow the carrier to pop open.
The battery can then be pulled out of the carrier. When installing a new battery into the carrier, make sure
the battery terminals are exposed and that the polarity matches the markings printed on the battery carrier.
Completely press the battery carrier down into the alarm and release, the battery carrier will lock into the closed
position. A missing or improperly installed battery will prevent the battery carrier from closing and result in
improper alarm operation.
Replace battery with one of the following approved brands:
Duracell MN1604, MX1604, Energizer 522 and Gold Peak 1604A.
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 alarm.
NOTE:
Do not use lithium batteries in this unit. 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.
