Ajax DoorProtect Plus U Jeweller Kablosuz Manyetik Kontak (Darbe ve Eğim Sensörlü)

Guardian for doors, windows, and valuables

DoorProtect Plus U Jeweller is a version of Ajax’s well-known opening detector, refined to meet strict UK standards. It secures the entry points most often targeted by intruders — including doors, windows, skylights, cabinets, and vaults. The device uses reed switch technology to detect opening, while a built-in accelerometer catches attempts to knock out, break, or tilt the door or window. With two magnet options and two reed switches, the detector can be installed on doors and windows of various designs.

No intruder goes unnoticed

At the heart of DoorProtect Plus U Jeweller is robust reed switch technology. The reed switch changes its state when the detector’s magnet moves closer or farther away. Users and the monitoring company instantly receive a notification in Ajax apps when the door or window is opened or closed. The device features two reed switch contacts. Thus, the magnet can be installed on either the right or left side, providing greater flexibility during installation. This ensures accurate and efficient detection, no matter where the device is mounted.

Flexible installation with two reed switches and two magnets of different sizes

Enhanced security with additional detectors

DoorProtect Plus U Jeweller can expand the entry point setup by integrating third-party detectors. With a connector for a third-party device, the detector can add an existing or new wired opening, motion, or vibration detector with an NC contact to an Ajax system. This can extend the coverage area, incorporate already installed devices, and manage them seamlessly in a single Ajax app — all within one unified security ecosystem.

More than just a detector

When paired with an Ajax siren or keypad with a built-in buzzer, DoorProtect Plus U Jeweller can function as a shopkeeper’s bell, signaling a visitor’s arrival. Installers can assign one of four available sound patterns to different entrances. This way, it will be easy to tell whether someone opened the main door or a back entrance. All settings are configured remotely with a few clicks in an Ajax app.

Wire-free flexibility and reliable performance

The wireless design of DoorProtect Plus U Jeweller provides maximum installation flexibility — with a hassle-free setup and no extra steps for the device to begin operating. Each device battery is thoroughly tested during production, and Ajax Systems inspects every unit to guarantee reliable performance. After up to five years of autonomous operation, the battery can be easily replaced. Its status is always visible in Ajax apps. Users and monitoring companies receive low battery notifications months in advance, so the replacement is always well-timed.

Unique wireless technology

Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.

Communication through steel and concrete

Some facilities have thick walls, metal partitions, or sheer distances that affect signal quality. Ajax range extenders are designed to increase the range of a wireless network and deliver stable connection with a hub despite the obstacles. And by choosing the model with an Ethernet cable connector, you get an additional communication channel. А single system can accommodate up to five range extenders.

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 ARCs and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.

Sabotage protection

DoorProtect Plus U Jeweller has a tamper button that detects dismantling. The system instantly alerts the monitoring company and users if the device is detached from the mounting panel or removed from the surface.

All data stored and transmitted in the system is protected by block encryption with a dynamic key. This encryption makes reprogramming the device and replacing or stealing the data extremely difficult.
