Ajax Superior LineProtect Fibra Wired Line Sabotage Protection Module

Ajax Superior LineProtect Fibra

The Ajax Superior LineProtect Fibra is a wired protection module built to shield hubs and connected devices on a Fibra line from electrical sabotage. Positioned anywhere along the wired Fibra line, it acts as a safeguard against deliberate attacks such as short circuits, mains voltage injection, or stun gun strikes, isolating the damage so the rest of the security system keeps running. As part of the Ajax Superior wired product range, it is designed for professional installations where resilience against tampering is critical.

Key Features

• Sabotage detection: Continuously monitors input and output voltage on the Fibra line to identify short circuits, overvoltage, or stun gun attacks.
• Fuse-based isolation: Activates built-in fuses to cut power to devices downstream when abnormal voltage is detected, containing the fault.
• Line segment protection: Protects all Fibra devices and the hub itself located between LineProtect and the hub.
• Long output reach: Supports an output line of up to 2000 metres when using standard UTP cat.5 twisted pair cable.
• Low power draw: Operates on minimal energy, keeping overall system consumption efficient.
• Instant alerts: Sends notifications identifying the specific type of sabotage event to the Ajax app and monitoring station.
• Remote management: Can be tested, configured, and monitored remotely through the Ajax app without a site visit.
• Flexible placement: Can be installed behind the hub or behind a detector, keypad, or siren depending on project design.
• Tamper-aware housing: Fits into the optional Case enclosure, which includes tamper boards for physical intrusion detection.

Where LineProtect Fits in a Fibra System

LineProtect is best installed just before devices that are exposed to tampering risk, such as outdoor sirens, keypads, or entry-point detectors. By placing it strategically along the Fibra line, installers can localise any sabotage attempt so it only affects the segment beyond the module, while everything between LineProtect and the hub continues operating normally. This makes it a valuable addition to commercial and residential wired security installations that need a higher standard of tamper resistance.

Frequently Asked Questions

Does LineProtect require its own power supply?
No, it draws power directly from the Fibra line and does not provide additional power to devices further down the line.

Can multiple LineProtect modules be chained together?
No, only one LineProtect can be connected per Fibra line, and units should not be installed one after another.

Is a casing included?
No, the protective Case with tamper boards is sold separately and is available in multiple size variants.
