Key specifications

How to use

Position the sensor body and the magnetic actuator on the fixed frame and moving sash respectively, keeping the recommended alignment and gap for reliable contact operation. Secure both parts using screws or adhesive as appropriate for the mounting surface. Connect the sensor’s switching contacts to the alarm panel or automation input following the system manufacturer’s wiring diagram. After wiring, test the open and closed positions to confirm correct signalling and adjust alignment if necessary.

Recommendations

For reliable operation, mount the sensor on clean, dry surfaces and avoid locations where strong external magnetic fields or metal obstructions could affect the reed contact. Verify compatibility with the control panel’s input type (normally open/closed) before installation and perform functional tests after installation and during routine maintenance checks.
