The DoorProtect operates up to 7 years without battery replacement.
The external contact is able to connect to third-party detectors.
There are two magnet sizes for installation on narrow frames and door frames.
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.
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.
