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 battery connector, a low battery
condition is indicated by the panel. When the battery falls below 3.60 V, a red battery icon
displays on the main screen and
KEYPAD - LOBAT
will display in the Status List. To restore
the keypad from a low battery state, the voltage must be above 3.62 V.
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.
