Battery Absent

Verify the battery is properly wired and securely in place. If so, the battery may need to be replaced.

For panels, most have a special battery pack located behind the back cover of the panel. For device-specific information regarding battery replacement, see the panel-specific guide for Battery Replacement or refer to the panel installation guide in Panels.

If the device does not show a battery absent trouble locally but Alarm.com does, verify a restore signal from the device is sent. To verify a restore signal is sent:

1. Remove the battery.
2. Verify a battery absent signal is triggered.
   • The device may need to be power cycled to trigger the battery absent signal.
3. Wait a few minutes for the battery absent signal to send.
4. Plug the battery back in to get a restore signal.
5. Allow a few minutes for the battery absent restore signal to send. The trouble condition clears once the system sends a successful restore.
