Guardian for doors, windows, and valuables
DoorProtect Jeweller is a wireless opening detector designed to secure doors, windows, and skylights by detecting intrusion or burglary attempts. It features a British-made reed switch rated for over 2 million openings. The detector comes with magnets of two sizes for flexible installation even on narrow window and door frames. DoorProtect Jeweller is powered by a pre-installed battery, ensuring operation for up to 7 years.

High-end reed switch for reliable detection
The core functional component of DoorProtect Jeweller is a reed switch — a small flask housing an open contact group. Encased in a durable plastic capsule, the reed switch ensures decades of reliable operation and remains unaffected by drops or transportation.

• Effective detection with the magnet on the right
• Plastic capsule to protect the reed switch

Enhanced security with additional detectors
DoorProtect Jeweller features terminals for connecting any third-party wired detector with an NC contact type3 to enhance the reliability of the entire system. For example, an additional opening detector with a different operating principle can be integrated, or even a motion or vibration detector. When connected to DoorProtect Jeweller, these devices can raise alarms either independently or along with the opening detector.

Never miss a visitor
The Chime feature transforms an Ajax opening detector along with an Ajax siren into a traditional doorbell. When the system is disarmed, the siren notifies users about doors being opened with one of four available short beep patterns. PRO users can adjust the signal volume and assign different patterns to each entrance, making it easy to recognize which door was opened.

Wire-free flexibility and stellar performance
DoorProtect Jeweller powered by the pre-installed CR123A battery for a hassle-free wire-free setup. While these batteries undergo real-time testing during production, Ajax Systems additionally inspects every unit to verify the accuracy of its characteristics. The battery is easily replaceable and offers up to 7 years of autonomous operation. Battery status is always accessible in an Ajax app, with users and the monitoring company receiving low power warnings months in advance.

System supervision
All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, including tamper, communication, power supply, and sensor states, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for security companies and users. If there is any malfunction or communication failure, an engineer will be immediately informed to provide the necessary services.

• Automatic device self-diagnosis with status report
• Regular polling to display the current device state on apps
• Instant maintenance notifications
