Principle of operation

The device detects the door or window being opened by means of British-made hi-end reed switches on which the magnetic field acts. It can operate in the transmitter mode, sending a signal from the wired sensor to the hub.

Features

The device consists of two modules — detector and magnet. The set includes two magnets: the big magnet is installed at a distance of up to 2 cm, and the small magnet up to 1 cm.

Wireless opening sensor Ajax DoorProtect

Reed switches or sensors for opening doors and windows are used to protect the premises from intrusion. Such sensors determine the opening of doors, hatches, windows and other elements. A reed switch is a sealed switch that operates based on ferromagnetic spring contacts. The principle of operation of the reed switch is as follows:
Two plates of nickel and steel are placed in a sealed glass flask.
A magnetic field is created in the flask, which causes the plates’ interaction and the sensor’s operation.

Installation and set up

Ready to operate straight out the box: the battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub in the mobile application. It can be mounted on the SmartBracket in just a few minutes.
