Fibra (Hybrid Alarm)
A fully wired alarm system that installs in hours, not days.
Fibra is Ajax's proprietary wired communication protocol — up to 100 devices on a single 2km line, zero manual programming, and ten anti-sabotage countermeasures built in. Pair it with Ajax's wireless Jeweller devices on one Hybrid hub for the best of both worlds.
100 devices per line
One 2km Fibra line, any mix of devices
~20 hrs to install
30-device system — about half a typical wired job
AES-128 + NIST cipher
Every device authenticated, every session encrypted
Wired security, without the wiring headaches.
Traditional wired alarm systems rely on EOL resistors and relay outputs — every zone needs its own home run back to the panel, and every fault means a multimeter and a lot of patience. Fibra throws that model out. Every Fibra device talks to the hub over a shared two-wire digital bus, using encrypted data packets instead of simple voltage changes.
That single design change is why a 30-device Fibra system installs in around 20 hours versus roughly 40 hours for a comparable traditional wired system — and why there's no programming required once it's wired in. Devices are recognised automatically the moment they're connected.
Four ideas that make Fibra work.
No relays, no EOL resistors — Fibra is a digital protocol from the ground up, purpose-built for security rather than adapted from general industrial bus standards.
Devices share one line
Up to 100 Fibra devices connect to a single hub line using a 4-core signal or 8-core U/UTP cable — no home runs, no dedicated zone wiring.
Each gets a time slot
A TDMA-style protocol gives every device a short, scheduled window to transmit, so 100 devices can report in without data collisions.
Every packet is confirmed
Communication is two-way and full-duplex. The hub confirms receipt of every alarm; if it doesn't, the detector keeps transmitting until it does.
Encrypted, instant
Data is protected with a proprietary NIST-certified cipher based on AES-128, and alarms reach the hub in as little as 0.15 seconds.
Three ways to run a Fibra line — pick what fits the site.
Fibra supports three wiring topologies, so the cable layout can match the building rather than the other way around.
Beam (Radial)
A single line runs out from the hub to every device on it. The simplest, most common layout for most sites.
Ring
Both ends of the line return to the hub. If the cable is ever cut, both halves keep working independently — the layout security-graded sites ask for.
Tree
A Superior LineSplit Fibra module divides one line into four, each extending up to 2km further — built for large or multi-building sites.
Mix wired Fibra and wireless Jeweller devices on the same system.
The Superior Hub Hybrid runs Fibra (wired) and Jeweller (Ajax's wireless protocol) side by side — up to 8 independent Fibra lines plus full wireless support, up to 100 devices total, all managed from one app and one monitoring account. Wire the areas that need Grade 3 wired reliability; go wireless everywhere else.
Where Fibra sits between traditional wired and wireless-only.
Three ways to protect a site, and three different trade-offs between install speed, resilience and flexibility.
| Traditional Wired | Fibra (Wired) | Wireless (Jeweller) | |
|---|---|---|---|
| Install time (30 devices) | ~40 hours | ~20 hours | ~10 hours |
| Programming | Manual, per zone | None — auto-detected | None — auto-detected |
| Tamper & line security | Basic EOL resistor | 10 anti-sabotage mechanisms + continuous line monitoring | Jamming & RF interference detection |
| Devices per line/hub | Typically 1 zone per run | Up to 100 per line | Up to 100 per hub |
| Best for | Simple, low-device-count sites | Grade 3 sites, harsh RF environments, large device counts | Fast retrofits, heritage buildings, flexible layouts |
Ten countermeasures, on by default.
System supervision
Continuous monitoring of tamper, comms, power and sensor state, with instant alerts.
Line breakage protection
Ring topology splits into two working segments if the cable is cut.
Alarm delivery confirmation
The hub confirms receipt; the detector keeps transmitting until it does.
AES-128 encryption
A proprietary NIST-certified cipher protects every data packet on the line.
Buffered backup
MotionCam devices store alarms and photos locally and sync once connection restores.
Device authentication
The hub authenticates every device each session, preventing spoofing.
Regular polling
Communication loss is detected in as little as 36 seconds at minimum settings.
Line voltage control
Constant monitoring flags voltage sags or spikes on the line instantly.
Short-circuit protection
Faults are detected instantly, with automatic restoration — no fuse to replace.
No data collision
The protocol handles simultaneous alarms from all 100 devices without data loss.

Plan your topology
Choose Beam, Ring or Tree based on the site — Ring for anywhere line security matters, Beam for straightforward runs, Tree for large or multi-wing buildings.
Run the cable
A single 4-core signal or 8-core U/UTP cable carries every device on the line — no home runs back to the hub per zone.
Connect and power up
Devices are recognised automatically the moment they're wired in. No manual programming, no per-zone configuration.
Commission from the app
Group devices, set up to 9 security groups and 36 automation scenarios, and the system is ready to arm.
