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.
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.
