I’m experiencing the same “AC Power Failure” message on alarm.com/in the app that others have experienced in the past. This is a new IQ Panel 2 Plus replacement panel. I powered down the panel last night disconnected the battery and let it sit overnight (8+ hours). Powered it back on, ran the cell test, logged out of the app and back in. Panel is showing battery 100% (Charging), odd but ac power and battery tests pass. Any other suggestions on how to clear this? Waiting to resolve this before mounting it back on the wall.
This is a known issue which is resolved in firmware 2.7.2. Update instructions are below:
Thanks Jason! For anyone else who might bump into it. I also resolved it with but simulating a power failure (pulled the supply), waited 10 minutes, plugged back in. Restoral message was received and cleared from alarm.com
