What to do if my DSC Control Panel shows a 'Panel Low Battery' warning?
- CChristina ShafferAug 21, 2025
If your DSC Control Panel displays 'Panel Low Battery', first, verify that the voltage measured across the AC terminals is between 16-18 VAC. Replace the transformer if needed. Next, disconnect the battery wire leads and check that the battery charging voltage measured across the battery leads is between 13.70 - 13.80 VDC. Finally, connect the battery, remove AC power, and ensure the voltage measured across the Aux terminals is at least 12.5VDC.
