WIRELESS
It’s a hybrid — not wired-only
The Ajax Hub Hybrid runs Fibra wired and Jeweller wireless devices on the same panel — up to 100 in any proportion. Wire the core of your building for maximum reliability, then add wireless sensors anywhere cabling isn’t practical. One system, one app, total flexibility.
Ajax Fibra is the wired product line of the Ajax system — all the intelligence of Ajax wireless, delivered over secure encrypted cable on the Hub Hybrid panel.
What is Ajax Fibra?
Fibra is Ajax’s wired communication technology. Where the wireless Jeweller protocol suits most homes, Fibra is built for projects where cable is preferred or required — commercial buildings, new builds where wiring can be laid during construction, and larger or steel/concrete structures where radio penetration is a concern. Every Fibra line is encrypted and authenticated, with advanced anti-sabotage and instant short-circuit notification.
The system runs on the Ajax Hub Hybrid, supporting up to 100 wired and wireless devices in any mix across eight independent lines. Even a complete break in one line leaves the system around 87% operational — fault tolerance traditional wired panels can’t match. Lines can be wired as a star topology or as eight zones, giving full design flexibility on complex sites.
Why an accredited Ajax installer matters
Fibra and the wider Ajax Superior range can only be purchased, installed and administered by accredited Ajax partners who have completed Ajax Academy training. SatFocus holds that accreditation — so your wired system is designed to standard, commissioned correctly and fully supported. We’ve completed 3,000+ installations since 2012 and are a Checkatrade member and Which? Trusted Trader.
Accredited Ajax Fibra & Superior installer
Fibra is restricted to accredited partners only. SatFocus is trained and accredited by Ajax to design, install and administer Ajax wired systems — your assurance the installation meets Ajax’s own installation standards.
Wired reliability, Ajax intelligence
Everything that made Ajax the benchmark — now over secure cable, for sites that demand it.
Encrypted & authenticated
Every line is encrypted with anti-counterfeit token authentication, blocking third-party devices and flagging tampering instantly.
2km independent lines
Up to eight lines, each up to 2km. A complete break on one line leaves the system around 87% operational.
Photo verification
MotionCam Fibra detectors capture photos on alarm, delivered to the Ajax app for instant visual confirmation.
Zero radio interference
Cable signalling is immune to RF jamming and congestion — ideal for steel/concrete and high-security sites.
Ultra-low power
Fibra devices draw up to 100x less than typical bus detectors; a Hub Hybrid battery runs 30 wired devices for around 60 hours.
One app, hybrid ready
Mix Fibra wired and Jeweller wireless on one hub, managed in the same Ajax app alongside CCTV integration.
