    Honeywell Glass Break - Loss of Supervision

      1. Ensure the panel is disarmed.

      2. Open the sensor by prying open the cover from the bottom using a flat-head screwdriver (or small coin).

      3. Replace the battery with a CR-123A battery.

      4. Fully close the sensor, pressing down on the bottom corners to ensure it snaps into place.

      5. Check the panel to ensure the error has cleared, if not replace the sensor battery.

      If the error persists, please call our Account Specialists at 855-238-4826 for further assistance.
