DoorProtect Operating Principle
DoorProtect consists of two parts: the detector with a sealed contact reed relay, and a constant
magnet. The detector is attached to a frame and the magnet - to a moving wing or sliding part. If
the sealed contact reed relay is within the coverage area of the magnetic field, it closes the
circuit - the detector is closed. The opening of the wing distances the magnet from the sealed
contact reed relay, resulting in the circuit opening, and the detector records opening.
A small magnet acts at a distance of 1 cm, and the big - up to 2 cm.
After actuation, the DoorProtect detector set in the intrusion detection mode immediately
transmits an alarm signal to the Ajax Hub, activating the sirens connected to the hub and
notifying the user and private security company.
