DSC PowerSeries Pro – Battery Replacement

The battery used for a DSC PowerSeries Pro depends on the desired standby time. Use the chart in this article to determine the required battery. Battery capacity deteriorates with age and the number of charge/discharge cycles. Replace every 3-5 years.

Note: For UL installations, a sealed, rechargeable, lead-acid battery or gel type battery is required to meet UL requirements for power standby times.

To replace the battery in a DSC PowerSeries Pro:

If desired, put the system in test mode with the monitoring station before proceeding. 

1. Disarm the panel.
2. Power off the panel.
   1. Remove AC power from the panel.
   2. Disconnect the panel from the mounting plate.
   3. Unplug the battery connector.
3. Remove the old battery.
4. Power on the panel.
   1. Install the new battery by connecting the RED battery lead to the positive battery terminal and the BLACK battery lead to the negative battery terminal.
   2. Reconnect the panel to the mounting plate.
   3. Restore AC power to the panel.

Note: Verify the panel does not display a Battery Absent trouble condition. If the keypad still displays a low battery message, the new battery may just need time for the panel to recharge it.
