Product Description

The AJAX#61340 Ajax Superior DoorProtect G3 Fibra is an advanced wired opening detector engineered for high-security residential, commercial, and industrial installations. Combining opening detection, shock detection, tilt monitoring, and magnetic masking protection in a single device, it delivers comprehensive perimeter security against forced entry attempts and tampering.

Unlike traditional magnetic contacts, the Superior DoorProtect G3 Fibra incorporates an accelerometer, magnetic masking sensor, and dual reed switches to detect door and window opening, impacts, vibrations, tilting, and attempts to bypass the detector using fraudulent magnets. Powered by Ajax’s encrypted Fibra communication technology, the detector provides fast alarm transmission, remote configuration, and exceptional reliability over distances of up to 2,000 metres.

Ideal for doors, windows, skylights, roller shutters, safes, and other vulnerable access points, the Superior DoorProtect G3 Fibra offers a professional-grade intrusion detection solution with enhanced protection against sabotage and sophisticated attack methods.
