Wireless door opening detector (DoorProtect)

Wireless opening detector that reports the first signs of intrusion into a room through a broken door or window. It can be mounted on all types of doors, including metal-based doors.

Operating principle:

The device detects the opening of doors or windows using high quality reed switches manufactured in the UK which are affected by the magnetic field. It can operate in transmitter mode and sends a signal from the cable sensor to the hub.


The device consists of two modules - detector and magnet. The set contains two magnets: The large magnet is installed at a distance of up to 2 cm and the small magnet at a distance of up to 1 cm.

Installation and setup:

Ready for use immediately: The battery is already installed, so there is no need to disassemble the detector. With one click it can be connected to the hub for mobile use. It can be attached to the SmartBracket bracket in a few minutes.


The Ajax alarm system has been extensively tested and has been awarded grade 2 certification in accordance with EN 50131 (for safety devices). Grade 2 is suitable for apartments, houses and offices.

- The alarm system sends alerts to the owner's smartphone and the monitoring centre.
- Control is via the mobile application (app) and the radio remote control.
- The system helps to prevent break-ins through entrances such as windows and doors.

Jeweller radio technology:

Is a cornerstone for the Ajax alarm system. Radio technology replaces yesterday's cables with modern radio communication between the components and achieves a maximum range of up to 2000 meters outdoors. This avoids the annoying laying of cables, the consideration of floor plans and the conversion of furnishings.
