The door / window magnetic contact consists of a transmitter and a magnet. The range of the transmitter is about 328 feet. The gap between transmitter and magnet can be up to 3/4-inch (20 mm). The installation of the door contact or the window contact can be done on the right and left on window or door frame. The alarm panel can be armed even with the window open, without triggering a false alarm. The opened window is not monitored. And due to the large distance between transmitter and magnet, tilted windows can also be monitored by mounting them at the bottom of the window. The delivery includes the adhesive pad and the battery.
