Ajax Fibra LineSplit Wired Line Splitter Module for Fibra Systems

Ajax Fibra LineSplit Module

The Ajax Fibra LineSplit is a wired expansion module built for professional Fibra-based security installations. It takes a single Fibra line and divides it into four independent output lines, giving installers far greater flexibility when running cable through multi-room sites. Because it can be placed at any point along an existing Fibra line, LineSplit is especially useful for renovation projects where legacy wiring needs to be reused rather than replaced.

Key Features

• Four-way line splitting - converts one Fibra line into four separate output lines from a single connection point.
• Long cable runs - each output line supports up to 2,000 metres using U/UTP cat.5 4x2x0.51mm (24 AWG) twisted pair cable.
• Daisy-chain capability - up to ten LineSplit modules can be connected one after another to extend a project further.
• Encrypted Fibra communication - uses Ajax's proprietary two-way wired protocol with device authentication to resist tampering and spoofing.
• Tamper connector - accepts a tamper board (supplied with the optional Case) that reports break-in attempts on the housing to the Ajax app.
• Low power draw - consumes only up to 0.22 W at peak, helping installers fit more devices on a single line.
• Remote management - can be tested, configured, and monitored remotely through the Ajax apps.
• Indoor rated - designed strictly for indoor installation, typically fitted inside the dedicated Ajax Case enclosure.

Ideal for Wired and Hybrid Security Upgrades

LineSplit is aimed at installers working on commercial or residential Fibra and hybrid Ajax systems who need to branch a single cable run into multiple zones without pulling new wiring back to the hub. It is particularly valuable when upgrading an older wired alarm system to Ajax, since existing cable topology - whether bus or analogue - can often be reused with Fibra devices connected through LineSplit and, where extra splitting already exists, matched with the appropriate number of modules.

Frequently Asked Questions

Does LineSplit supply extra power to the line?
No. LineSplit only splits the signal line; if additional power is required further along the run, an Ajax LineSupply Fibra module should be used.

Which hubs is LineSplit compatible with?
It works with Ajax Hub Hybrid (2G) and Hub Hybrid (4G). It is not designed to connect to other hubs, range extenders, ocBridge Plus, or uartBridge.

Do I need to buy a case separately?
Yes, the module is designed to be fitted inside an Ajax Case enclosure, which is sold separately and also houses the tamper board.
