The Ajax DoorProtect U Jeweller 121293.03.WH1 is a professional wireless opening detector designed to provide reliable protection for doors, windows, and other access points. Developed to meet strict UK security requirements, it provides immediate detection when a protected door or window is opened.

The detector uses dual reed switches to accurately identify opening events. Its flexible design allows the magnet to be positioned on either the left or right side of the detector, helping installers achieve a clean installation across different door and window configurations.

Two different-sized magnets are supplied, providing additional installation flexibility for narrow frames, larger surfaces, and varying gaps between the detector and the moving section of the door or window.

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

Integrated tamper protection provides an additional layer of security by alerting the system if an attempt is made to remove or interfere with the detector. Its compact white housing provides a discreet appearance suitable for modern residential and commercial interiors.
