Ajax Superior SeismoProtect G3 Fibra Black — Grade 3 Seismic Detector

Professional Grade 3 High-Security Ajax Superior SeismoProtect G3 Fibra Black Wired Seismic and Shock Detector for Safes, ATMs, and Critical Infrastructure

The Ajax Superior SeismoProtect G3 Fibra in black is a high-security wired seismic and shock detector designed for physical defense of high-risk assets, including fortified safes, Automated Teller Machines (ATMs), bank vaults, reinforced doors, and concrete or steel barriers. Engineered to comply with rigorous European EN 50131 Grade 3 standards, this device instantaneously detects structural vibrations produced by mechanical drilling, diamond cutting tools, grinders, hydraulic presses, thermal lances, and explosives.

To deliver uncompromising detection immunity against false alarms, the unit coordinates three sensing technologies. The piezoelectric sensor captures mechanical waves over a radius of up to 4 meters on concrete and up to 2 meters on steel structures. A 3-axis accelerometer detects violent physical impacts, leverage force, pushing, and tilt angle shifts (configurable from 5° to 25°). In addition, an integrated digital temperature sensor detects thermal tool attacks, triggering an immediate alarm when temperatures exceed 70 °C or rise faster than 5 °C within 5 seconds.

The package includes a built-in self-test device that performs automated or manual health checks on the piezoelectric sensor, immediately alerting the Monitoring Center (ARC) in case of any operational defect.

Comprehensive Anti-Tamper, Enclosure Drilling Protection, and Fibra Bus Technology

In full compliance with Grade 3 high-risk mandates, the SeismoProtect G3 Fibra features a flexible PCB trace network with Pogo pins to detect direct enclosure drilling or cutting attempts. Physical tampering protection is supported by two physical tamper switches monitoring front cover removal and detachment from the wall mounting surface.

Data transmission with the hub relies on the proprietary Fibra wired protocol, ensuring instant alarm delivery, dynamic key block encryption, short-circuit protection, and bus line lengths of up to 2,000 meters.
