Set your panel into program mode (refer to your specific alarm panel manual for menu details). When prompted, trigger the sensor by moving the magnet in and out of range — the panel will beep once the sensor is successfully learned in.
Note: on 2GIG panels, configure this sensor as a "5816" type, using loop 2.
The recessed sensor and magnet are designed to fit snug in a ¾" hole, with a small flange on the outer rim to prevent the case from being pushed too far in.
A low-battery signal is sent to the control panel automatically.
Note: removing the cover triggers a zone tamper signal to the control panel.
