I’m getting a Device Low Battery (Door Bell Chime) error and there is no battery in my door bell chime or my ADC VDB770 doorbell camera. The VDB770 is wired into the low-voltage regular doorbell wiring that goes into a transformer in the garage. The doorbell itself is a simple mechanical doorbell, no battery.
The low battery is coming from the Zone 6 sensor labelled Door Bell Chime It is programmed as 2GIG Doorbell and Sensor Type 23 - No Response Type (A special zone monitored for activity or inactivity . It does not affect security system status. Often used for a doorbell, liquor/gun/game cabinet, etc.)
The VDB770 can ring to some panels like the IQ Panel 2+ and IQ Panel 4, with video calls available on the panel screen, but it is not compatible in that way with the 2GIG GC2 which it looks like may be related to this question.
