Operating Principle

DoorProtect Plus consists of two parts: the detector and the constant magnet. The
detector is equipped with the sealed contact reed relay, built-in accelerometer, and
socket for a third-party wired detector.
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 opens the circuit. In such a way, the detector recognizes the
opening.
The DoorProtect Plus set includes two constant magnets. The small one works at
a distance of 1 cm, and the big one — up to 2 cm.
The detector can be positioned horizontally. If there is no need to detect opening,
use only the detector part (without magnets) and disable the primary detector in
the settings.
The accelerometer detects shocks and vertical deviation relative to the initial
position of more than 5°. DoorProtect Plus can be installed on windows, including
dormer windows, and the system can be armed when they are slightly open
(disable the primary detector in the settings рreviously).
If triggered, DoorProtect Plus immediately transmits the alarm signal to the hub,
activating the sirens and notifying the user and security company.
