Ajax DoorProtect Plus white opening sensor (DoorProtect Plus / white) The Ajax DoorProtect wireless sensor is designed to detect the opening of doors and windows. The sensor is equipped with a terminal block for connecting additional wire sensors, including wire opening sensors intended for installation on metal gates and hatches. The sensor consists of two parts - a magnet and a block with a reed switch. Two versions of the magnet are provided - for parallel (large magnet) and perpendicular (small magnet) installation. The principle of operation of the opening sensor is based on the properties of a reed switch - an element capable of becoming a conductor under the influence of a magnetic field. In a normal state, the magnet and the block with the reed switch are closed. As soon as the door on which the sensor is installed opens, the magnet moves away from the reed switch, the contacts open and the reed switch stops conducting current. When the door is closed, reverse processes occur: the magnet approaches the reed switch, the contacts close and the reed switch begins to conduct current. In both cases, the sensor is triggered and instantly sends an alarm message to the central unit. The English reed switch is installed in the sensor, which does not stick and works out more than a million closing / opening.
