DoorProtect & DoorProtect Plus is a wireless opening detector that notifies of first signs of room intrusion by means of a broken door or window.
It can be mounted on all types of doors including a metal base.

Features

  • Operates up to 7 years without battery replacement
  • External contact is available for connecting third-party detectors
  • Includes magnets of various sizes for installation on narrow frames and door frames

Principle of operation

DoorProtect consists of two parts: the detector with a sealed contact reed relay, and the constant magnet. Attach the detector to the door frame, while the magnet can be attached to the moving wing or sliding part of the door. If the sealed contact reed relay is within the coverage area of the magnetic field, it closes the circuit, which means that the detector is closed. The opening of the door pushes out the magnet from the sealed contact reed relay and opening the circuit In such a way, the detector recognises the opening.

After actuation, DoorProtect immediately transmits the alarm signal to the hub, activating the sirensand notifying the user and security company.

DoorProtect Plus

The DoorProtect Plus differs from the DoorProtect as it can protect windows left open for ventilation. The biult-in accelerometer registers changes in vertical slope angle, bangs or vibration and sends an alarm to the hub.
