We offer you to buy wireless door sensor designed to transmit the alarm signal to the Central unit wireless GSM alarm when unauthorized opening of doors, Windows, sunroof etc. One of the advantages of the infrared detector is the mobility, the sensor can be moved from one room to another without running additional wires. Sensors are indispensable in places where there is no electricity or cabling is invalid for some reason. All wireless detectors are addressable/digital, so you can convey more information about your condition. The sensor consists of two parts – a magnet and reed block. The principle of operation of the door sensor based on the properties of the reed switch element conducting the current under the action of an alternating magnetic field. In normal condition the magnet and the block with the reed switch closed. As soon as the door with a sensor opens, the magnet moves away from the reed switch, the reed switch opens and stops conducting a current – sensor triggered and transmit wireless alarm signal to the Central alarm unit. The sensor has a compact size and stylish design. The body has two LEDs. One of which lights up when you activate the sensor, and the second indicates when it is time to replace the battery.
