The DoorProtect Plus operates up to 5 years without battery replacement.
It registers a change in vertical slope angle, bangs and vibration.
The external contact is available for connecting third-party detectors.
The device can even protect windows that have been left open for ventilation. The accelerometer registers changes in vertical slope angle, bangs or vibration and sends an alarm to the hub.
Principle of operation
The DoorProtect Plus 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.
