To detect unauthorized access, this surface mount magnetic contact must be installed, fully aligned, respectively on the fixed part and the moving part of the door or window that opens into the area to be protected. When the magnetic contact is in proximity of the switch, closed door or window, the reed contacts are closed and radio transmission is disabled. When the magnet is moved away from the switch (2cm gap), opened door or window, the reed contacts are opened. This will activate a radio signal to the Gemini alarm system onboard the vehicle.
