Backup Battery Replacement
Backup batteries have a limited service life. The length of time a battery lasts
depends on many factors, including the charging rate, number of discharge
cycles and the ambient temperature at the installation site. If a backup battery
is found to be defective, follow these steps to replace it:
1. Turn off the primary power to the station.
2. Unplug the battery cable from J4 on the Interface/Utility Board.
3. Remove the battery bracket screws and the battery pack. Properly discard
the defective battery.
4. Install the new battery pack and re-install the battery bracket.
5. Connect the cable assembly between the battery and J4 on the Inter-
face/Utility Board.
6. Re-apply primary power to the station.
