Ajax DoorProtect White Wireless Magnetic Door & Window Opening Detector

Ajax DoorProtect White – Wireless Opening Detector

The Ajax DoorProtect is a compact wireless magnetic contact sensor built to guard doors, windows and skylights against unauthorised opening. Pairing a reed switch with a magnet, it forms part of the Ajax Jeweller ecosystem, sending instant, encrypted alerts to the hub the moment a protected opening is disturbed. Finished in white, it blends discreetly into most door and window frames while delivering long-term, low-maintenance protection for homes, offices and small commercial sites.

Key Features

• Long-life reed switch: Uses a British-made reed switch engineered for well over two million opening cycles, ensuring reliable detection for years of daily use.
• Dual magnet kit: Ships with two magnet sizes, giving installers flexibility on narrow window frames as well as standard door frames.
• Long battery life: Runs on a pre-installed battery rated for up to seven years of operation, minimising maintenance visits.
• Encrypted Jeweller connection: Communicates with the Ajax hub over the two-way, encrypted Jeweller radio protocol with a line-of-sight range of up to 1,200 metres.
• Wired input for extra sensors: Includes a terminal for connecting a third-party NC (normally closed) wired detector, letting installers add motion, vibration or secondary opening sensors to the same zone.
• Chime/doorbell mode: Combined with an Ajax siren, the detector can be configured to chime with one of several beep patterns whenever a monitored door opens while the system is disarmed.
• Tamper protection: A perforated section on the SmartBracket mounting panel triggers a tamper alarm if the unit is forcibly removed from its surface.
• Simple app-based setup: Paired and configured through the Ajax mobile and desktop apps, with QR-code pairing for fast installation.
• Indoor-rated, discreet design: A compact, low-profile white housing suited to indoor doors, windows and skylights.

Where It's Used

DoorProtect White is ideal for securing entry doors, sliding doors, windows and skylights in houses, apartments, offices and retail premises that already run (or plan to run) an Ajax alarm system. It's commonly deployed as a standard opening sensor throughout a property, and its chime function makes it equally useful as a customer-entry alert on shop and office doors.

Frequently Asked Questions

Does DoorProtect need an Ajax hub? Yes. It communicates over the Jeweller radio protocol and requires an Ajax hub (or compatible range extender) to operate within a security system.

Can it be used outdoors? No, DoorProtect White is designed for indoor installation on doors, windows and skylights only.

Can I add another sensor to the same detector? Yes, it has a terminal for connecting one third-party wired detector with a normally closed (NC) contact, such as an additional motion or vibration sensor.
