Standby Battery
The keypad rechargeable battery provides 12 hours of backup battery power when
primary AC power is not available. It is shipped already installed inside the keypad.
The battery is intended for backup power only and not to operate the keypad on
a daily basis. If the battery is low, or not plugged into the internal J3 battery
connector, a low battery condition is indicated by the panel. When the battery is low,
a red battery icon displays on the main screen and KEYPAD - LOBAT will display in the
Status List.
Use the following steps to replace the battery. DMP recommends replacing the
battery every 3 years under normal use.
Note:
If removing the keypad from service, disconnect the power supply connector
from the back of the keypad to avoid discharging the battery.
