Ajax Systems Architecture for Integrators: Hubs, Jeweller and Fibra
Ajax Systems builds its ecosystem around a central hub, wireless Jeweller sensors and — where wired detection makes more sense — the Fibra bus. This overview breaks down when to specify each, so you can size a system that fits the site, not just the catalogue.
Choosing the right architecture
Pick the hub
Hub 2 and Hub 2 Plus run Jeweller wireless devices; Hub Hybrid additionally supports wired Fibra devices on the same controller — useful when a project mixes both.
Deploy Jeweller for speed
Ajax's proprietary wireless protocol links sensors to the hub with no cable runs. Open-field range is rated up to ~2 km line-of-sight; expect less indoors depending on walls and construction materials.
Specify Fibra where wired makes sense
Fibra is Ajax's own wired protocol/bus, an alternative to Jeweller on the same ecosystem — appropriate where cabling already exists, RF interference is a concern, or the client requires hardwired detection.
Add photo verification where it matters
MotionCam detectors capture a photo on alarm, transmitted quickly via Wings technology, giving the end user or monitoring station visual confirmation before dispatch.
Architecture at a glance
Jeweller open-field range
The established line-of-sight figure for Ajax's wireless protocol — real-world indoor range is always lower and depends on walls and materials.
Hub 2 / Hub 2 Plus / Hub Hybrid
Central controllers for the ecosystem; Hub Hybrid is the model that runs wireless Jeweller and wired Fibra devices together on one hub.
Jeweller wireless protocol
Ajax's proprietary radio link between sensors and hub — fast to install, no cable runs, ideal where structural or aesthetic constraints rule out wiring.
Fibra wired protocol
A wired bus alternative to Jeweller within the same ecosystem, suited to sites with existing cabling, RF-sensitive environments, or hardwired-only specifications.
MotionCam photo verification
Motion detectors with a built-in camera capture an alarm-event photo, transmitted via Wings — helps confirm a real event before escalating, though it does not eliminate false alarms outright.
Monitoring and apps
Hubs connect to professional 24/7 monitoring stations via the operator's monitoring software; installers configure through the PRO app, end users arm and monitor through the Security System app. Many devices are certified to EN 50131 Grade 2 — verify per device for graded-risk projects.

Frequently asked questions
When should I specify Fibra instead of Jeweller?
Choose Fibra where cabling already exists, the site has RF interference risk, or the client's policy requires hardwired detection. Jeweller remains the faster, cable-free option for most retrofit and standard installs.
Can Hub Hybrid run wireless and wired devices at the same time?
Yes — Hub Hybrid is built to support Jeweller wireless devices and Fibra wired devices on one controller, which is useful for mixed-requirement sites. We don't publish exact device-count capacities here; check the current datasheet for your project's device load.
Is the ~2 km Jeweller range realistic indoors?
No — ~2 km is the open-field, line-of-sight figure. Indoors, range drops depending on walls, floors and building materials, so always plan hub and sensor placement with a site survey rather than the headline figure.
Does MotionCam eliminate false alarms?
No. It adds photo verification so the end user or monitoring station can visually confirm an event before acting, which reduces false-alarm response — it doesn't guarantee every alarm is genuine.
Are all Ajax devices certified to EN 50131 Grade 2?
No — many devices are certified to EN 50131 Grade 2, but not the entire range. For graded-risk projects, verify certification on a per-device basis before specifying.
