The Ajax DoorProtect U Jeweller 121294.03.BL1 is a next-generation wireless opening detector designed to provide reliable protection for doors, windows, and other vulnerable access points. Developed to meet strict UK security requirements, it combines accurate opening detection, secure wireless communication, and tamper protection in a compact black housing.

Equipped with dual reed switches, DoorProtect U accurately detects when a protected door or window is opened. The flexible design allows the magnet to be installed on either the left or right side of the detector, making installation easier across different types of doors, windows, and frames.

The detector is supplied with two magnets of different sizes, giving installers greater flexibility when working with narrow frames, larger surfaces, or different gaps between the detector and the opening section.

When the security system is armed and the magnetic contact is broken, DoorProtect U immediately communicates the event to the compatible Ajax hub using the secure Jeweller wireless protocol. The system can then activate the alarm and send notifications to users through the Ajax app.

Integrated tamper protection provides an additional layer of security by alerting the system if somebody attempts to remove or interfere with the detector. Its slim and discreet design allows it to blend neatly into modern residential and commercial interiors.
