Ajax Fiber

Ajax Fibra: the professional wired alarm system

Fibra is the wired version of the Ajax ecosystem. Same devices, same app, same configuration logic—but a wired connection instead of radio. It's Ajax's answer to installations where wireless reaches its limits.

When to choose Fibra over Jeweller?

Building under construction or in shell. If conduits are accessible, wiring costs almost nothing and permanently eliminates the battery issue.

Saturated radio environment. Office buildings, shopping centers, industrial sites: the 868 MHz band can be congested. Fibra experiences no interference.

Long distances. Each Fibra line supports up to 2,000 meters of cable, allowing coverage of an extended site, annexed buildings, or multiple levels without a repeater.

Regulatory requirements. Some specifications and insurance policies require a wired connection at sensitive points.

No battery maintenance. For an installation with a hundred detectors, replacing batteries every five to seven years represents a real operating cost. Fibra eliminates it.

Fibra Architecture

A Hybrid Hub controls up to eight Fibra lines. Each line can be split if necessary with a LineSplit (up to four sub-lines), and is protected with a LineProtect against short circuits, 230V surges, and sabotage. Finally, the MultiTransmitter Fibra allows integrating third-party wired detectors into the system.

Can Fibra and Jeweller be mixed?

Yes, and it's often the best solution. The Hybrid Hub simultaneously manages both protocols. In renovations, what is accessible is cabled, and wireless is used where drilling would be too expensive. The result is a single system, controlled from a single application.

Frequently Asked Questions

What cable should I use?
A standard twisted-pair alarm cable is suitable. The cross-section depends on the line length and the number of powered devices.

Is Fibra safer than Jeweller?
Both protocols are encrypted and constantly monitored. Fibra simply eliminates the risk of radio jamming, which remains marginal but exists on sensitive sites.

Do Fibra devices work with a Hub 2?
No. Fibra requires a Hybrid Hub or a Hub with Fibra lines.
