Ajax - Wireless magnetic opening detector with shock and tilt sensor (Ajax DoorProtect Plus)

DoorProtect Plus is a wireless opening, shock, and tilt detector, that operates within the Ajax security system, connecting via the protected Jeweller radio protocol. Is used inside premises. The communication range is up to 1,200 m line of sight. DoorProtect Plus can operate up to 5 years from a pre-installed battery and capable to detect more than one million openings.

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.

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).

Features

The device protects even windows left open for ventilation. The accelerometer registers changes in vertical slope angle, bangs or vibration and sends an alarm to the hub.

Installation and set up

Ready to operate straight out the box: the battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub in the mobile application. It can be mounted on the SmartBracket in just a few minutes.
