- This condition occurs when the panel is no longer receiving power from the transformer.
- Check for a possible AC power outage.
- Check breakers.
- Check the transformer, see if it may have been accidentally unplugged or look for any loose wires, make sure your AC wires are connected.
- When an AC Power Failure occurs, the backup battery will take over (If fully charged, it will last for 18-72 hours with no AC power) If AC power is not restored within 15 seconds, control panel will alert you with trouble beeps. Pressing SYSTEM STATUS or # twice will confirm the AC power failure.
- If the failure was not caused by the above conditions, please contact TNT Security Technical Support
