First Steps Before You Call

Identify which device is reporting

The panel or app will name the zone or sensor. That tells us where to start.

Check for a low battery warning

A surprising share of faults come down to a sensor battery rather than the panel itself.

Confirm the panel is online

If the panel has lost connectivity, the fix is different from a single failed sensor.

Have your passcode ready

Account changes need verification, so have the verbal passcode to hand before you call.
