What to do if my DSC PowerSeries Security System shows 'Low Battery'?
- TtroyfrazierAug 16, 2025
If your DSC Security System indicates a low battery, it could be because the main panel battery voltage is less than 7.2VDC. If the battery is new, allow 24 hours for it to charge. Check that the voltage measured across the AC terminals is 16-18 VAC, and replace the transformer if needed. Also, try disconnecting and then reconnecting the battery leads.
