Ajax Superior DoorProtect G3 Fibra White — Grade 3 Magnetic Contact

Professional Grade 3 High-Security Ajax Superior DoorProtect G3 Fibra White Wired Magnetic Contact with Dual Sensors and Shock Detection

The Ajax Superior DoorProtect G3 Fibra in white is a high-performance wired door and window contact engineered to protect critical perimeter points in commercial buildings, financial institutions, sensitive infrastructure, and high-risk environments. Designed in full compliance with stringent European EN 50131 Grade 3 security standards, this detector delivers ultimate resistance against advanced magnetic bypass attempts and physical tampering.

Unlike standard magnetic contacts, the DoorProtect G3 Fibra incorporates two high-precision Hall-effect sensors, allowing it to detect not only door separation but also external magnetic field manipulation or spoofing using external magnets. Furthermore, an integrated 3-axis accelerometer detects physical impacts, violent shocks, and tilt changes before the door or window frame is breached.

Auxiliary Input for External Sensors, Advanced Anti-tamper, and Fibra Technology

To extend coverage at the same entry point, the unit features an auxiliary wired N.C. (Normally Closed) terminal, allowing connection of external third-party detectors like heavy-duty roller shutter contacts or glass break sensors. Physical protection includes a triple anti-tamper mechanism guarding against case opening and wall detachment from the SmartBracket mount.

Communication with the hub relies on the proprietary wired Fibra protocol, providing instantaneous alarm delivery, dynamic key block encryption, short-circuit protection, and bus line support up to 2000 meters.
