Digital Monitoring Products Inc PC0132 User Manual

The keypad rechargeable battery provides 24 hours of backup battery power when 

primary DC 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 falls 

below 3.62 volts. To restore the keypad from a low battery state, the voltage must 

be above 3.62.
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.

1. Disconnect the battery lead connector from the keypad J3 battery header.
2. Squeeze the battery straps to remove the standby battery.
3. Observe polarity and connect the battery lead connector to the keypad J3 

battery header. See Figure 11.

4. Place the new battery (DMP Model 9800BAT) on the keypad PCB and replace 

the battery straps.

5. Properly dispose of the used battery. 

Caution: Risk of fire, explosion, and burns. Do not disassemble, heat above 

212°F (100°C), or incinerate.
