The Panel Low Battery trouble condition indicates the backup battery in the control panel is drained. This usually occurs after an AC power failure.
How to resolve:
- Verify the AC power is connected and allow time for the battery to recharge. This can take up to 24 hours in most cases.
- If it is unable to recharge, replace the system’s backup battery. For panel-specific information about recharging or replacing the panel battery, refer to the specific panel’s manual
