Product Description
The AJAX#61384 Ajax Superior LineProtect Fibra is a specialised protection module designed to safeguard Ajax Fibra devices and communication lines against sabotage attempts, electrical faults, overvoltage incidents, and malicious attacks. Built specifically for professional wired Ajax security systems, LineProtect acts as a protective barrier between the hub and connected Fibra devices, helping maintain system integrity in demanding commercial and high-security environments.
The module protects against short circuits, overvoltage on Fibra signal lines, stun gun attacks, and accidental application of 110V/230V AC voltage to the Fibra line. When abnormal conditions are detected, the system immediately notifies users and monitoring stations, allowing rapid response to security or electrical threats.
Ideal for commercial properties, government facilities, industrial sites, warehouses, educational institutions, and critical infrastructure installations, Superior LineProtect Fibra enhances the resilience and reliability of professional Ajax Fibra deployments.
