Ajax Wireless Alarm Systems: The Complete UK Installer Guide 2026

If you fit intruder alarms in the UK, Ajax is now the wireless system your customers ask for by name — and the range has grown far beyond a hub and a couple of PIRs. This pillar guide walks CCTV and security installers through the complete Ajax wireless alarm system: how the Jeweller and Wings radio platform works, how to choose between Hub 2 (2G), Hub 2 (4G) and Hub 2 Plus, which detector fits which risk, photo verification, sirens, keypads, range extenders, wired integration, starter kits and UK compliance (EN 50131 Grade 2 and PD 6662:2017). Netview is a UK Ajax stockist in Leicester with same-day dispatch on the full range at netviewcctv.co.uk.

At a glance

One app, one radio platform: every Ajax device talks to the hub over the encrypted two-way Jeweller protocol — up to 2,000 m open-space range on Hub 2 Plus.
Three panel choices: Hub 2 (2G) and Hub 2 (4G) support up to 100 devices; Hub 2 Plus doubles that to 200 and adds Wi-Fi.
Photo verification: MotionCam detectors deliver a photo series from the detector within seconds of an alarm over the dedicated Wings radio channel.
UK-compliant: the wireless range is certified to EN 50131 Grade 2 and, since OS Malevich 2.10, configurable to PD 6662:2017 for confirmed-alarm installations.
Batteries measured in years: up to 7 years on DoorProtect, up to 5 years on MotionProtect — service visits, not battery call-outs.

Why do UK installers choose Ajax?

Ajax wins UK installs because it combines consumer-grade design with professional-grade radio, certification and monitoring support. The kit looks good enough to leave on show in a living room or a boutique shopfront, but underneath it is a Grade 2 professional system: two-way encrypted radio with frequency hopping, tamper detection on every device, jamming detection at the hub, and a PRO app (Ajax PRO: Tool for Engineers) that lets you configure, test and maintain every customer site remotely. For a CCTV installer adding intruder to the offer, the learning curve is short: no panel programming keypads, no EOL resistor charts on the wireless side — enrolment is a QR-code scan per device.

How do the Jeweller and Wings radio protocols work?

Jeweller is Ajax's proprietary two-way radio protocol and it is the reason the system feels instant. It runs in the 868.0–868.6 MHz band with AES block encryption, self-adjusting RF power up to 25 mW and a detector polling period configurable from 12 to 300 seconds, with a communication range of up to 2,000 m in open space to Hub 2 Plus (Ajax Hub 2 Plus technical specifications). Alarms are delivered in well under a second, and because the link is two-way the hub knows immediately if a detector goes offline, is tampered with, or is being jammed.

Wings is the parallel photo channel: a separate encrypted radio protocol with its own antenna, used purely to move MotionCam photo series to the hub so image traffic never delays an alarm signal (Ajax Support: photo verification features). In real UK buildings — brick internal walls, foil-backed insulation — plan conservatively, survey with the Jeweller signal strength test in the PRO app, and drop in a ReX 2 range extender where a remote outbuilding or a long steel-framed retail unit pushes the link margin.

Which Ajax hub should you fit: Hub 2 (2G), Hub 2 (4G) or Hub 2 Plus?

Fit Hub 2 Plus on anything commercial or multi-group residential, and a Hub 2 (4G) on standard domestic jobs — the deciding factors are device count, communication paths and groups. All three panels support MotionCam photo verification. Per the manufacturer's specifications for the Hub 2 (4G) and Hub 2 Plus: Hub 2 manages up to 100 devices, 25 video cameras, 50 rooms and 9 security groups, while Hub 2 Plus doubles capacity to 200 devices and adds Wi-Fi alongside Ethernet and dual SIM, with support for up to 5 range extenders and backup-battery running into double-digit hours.

Spec	Hub 2 (2G)	Hub 2 (4G)	Hub 2 Plus
Devices	100	100	200
Comms paths	Ethernet + 2×SIM (2G)	Ethernet + 2×SIM (2G/3G/LTE)	Ethernet + Wi-Fi + 2×SIM (2G/3G/LTE)
Security groups	9	9	25

Which Ajax motion detector fits which room?

Choose by risk and by what the monitoring station needs to see: standard PIR for most rooms, dual-sensor PIR where heaters or draughts cause false alarms, and MotionCam wherever visual confirmation earns its keep. The current UK line-up is the U-series (UK/EU spec), and every model below is a stocked Netview line.

Detector	Sensing	Pick it when
MotionProtect U	PIR, pet-tolerant settings	The default room detector on most jobs
MotionProtect Plus U	PIR + K-band microwave	Conservatories, kitchens, draughty or heat-noisy rooms
MotionCam U (PhOD)	PIR + camera, photo on demand	Monitored sites needing visual alarm confirmation
CombiProtect	PIR + acoustic glass-break	One device covering a room and its window

How does MotionCam photo verification work?

When a MotionCam detector trips, its built-in camera captures a short photo series and sends it to the hub over the dedicated Wings channel, so the app and the monitoring station see what caused the alarm within seconds (Ajax Support: photo verification). On the Hub 2 family the series arrives as an animated sequence shortly after triggering (Ajax Hub 2 product page). Photo-on-Demand (PhOD) models such as the MotionCam U (PhOD) add the ability for authorised users to request a photo at any time — invaluable for an ARC operator deciding whether to escalate, and for cutting false-alarm call-outs. Our MotionCam photo verification guide covers privacy settings, PhOD permissions and ARC workflows in depth.

How do you protect doors, windows and glass?

Perimeter detection means the alarm sounds before anyone is inside — on UK stock that is DoorProtect U on standard openings (reed contact, battery life up to 7 years per the DoorProtect specifications), DoorProtect Plus where you also want shock and tilt sensing on vulnerable doors, shutters and skylights, and GlassProtect U listening for the acoustic signature of breaking glass on large panes. For the full perimeter playbook — including CombiProtect and wired-contact integration — see Ajax DoorProtect & GlassProtect: the UK installer's guide.

What about outdoor detection?

Ajax treats the garden as the first detection zone, not a gimmick: MotionProtect Outdoor is a dual-PIR outdoor detector with anti-masking and pet immunity for yards and driveways; MotionCam Outdoor adds photo verification outside; and DualCurtain Outdoor throws two narrow curtain beams along a building line or fence run to catch an approach before contact. Pair outdoor detection with an Ajax-triggered CCTV scenario — most of our installers run Ajax alongside a Hikvision NVR so a garden trip pulls up the relevant camera in seconds.

Which keypads and arming devices should you offer?

Offer the KeyPad TouchScreen as the default arming station on new installs — it arms by code, Tag, Pass card or smartphone and reads cleanly in daylight — with SpaceControl keyfobs for pockets and the outdoor-rated Keypad for gate posts and porches. Group arming from the keypad maps neatly onto Hub 2 Plus's 25 groups for shops with stockrooms or HMOs with private zones. Our Ajax keypad comparison ranks every model by job type.

Which sirens complete the deterrent?

Every quote should carry at least one internal and one external sounder: the HomeSiren U indoors, and the StreetSiren DD DoubleDeck outside, which takes a snap-on branded Brandplate so the box on the wall advertises the system protecting it. A dummy DoubleDeck on the far elevation doubles the visual deterrent for pennies. Full decibel ratings, IP ratings and mounting guidance live in our Ajax sirens installer guide.

How do you extend range and integrate wired kit?

Two accessories rescue difficult sites: the ReX 2 range extender re-broadcasts Jeweller and Wings (so photo verification survives the hop) for outbuildings, basements and long steel sheds, and the MultiTransmitter converts up to 18 zones of existing wired detectors — PIRs, contacts, panic strips — into supervised Ajax wireless zones. That makes a full takeover of an ageing wired panel a half-day job: leave the cabling in the walls, bin the panel, keep the detectors. Step-by-step wiring diagrams are in the MultiTransmitter installer guide.

Ajax starter kits: what is in the box?

Kits are the fastest way to quote a standard domestic install — one SKU, one price, everything paired out of the box. All Netview Ajax kits ship with UK-spec devices.

Kit	Contents	Arming	Typical job
Hub2 Kit 1	Hub 2, 2×PIR, 1×contact, internal + external sirens	2×keyfobs	Flat / small house
Hub2 Kit 3	Hub 2, 2×PIR, 1×contact, internal + external sirens	KeyPad	Family house, keypad-first customers
Hub2 DD Kit 1	As Kit 1 with StreetSiren DoubleDeck outside	2×keyfobs	Kerb-appeal deterrent installs

Which kit for which customer — and when to build à la carte instead — is covered in our Ajax StarterKit UK guide.

Is Ajax compliant for UK insurance and police response?

Yes — the Ajax wireless intruder range is certified to EN 50131 Grade 2, and since the OS Malevich 2.10 firmware update the system can be configured to comply with PD 6662:2017, the UK scheme for intruder and hold-up alarm installations (Ajax: compliance with PD 6662:2017; coverage in PSI Magazine). That update added alarm confirmation, two-stage arming, system restoration after alarm and alarm-transmission delay on entry — the building blocks BS 8243 expects for confirmed alarms and police response eligibility. For installers, the practical points are: configure confirmation in the PRO app, document it, and pair the system with an NSI- or SSAIB-recognised ARC if the customer wants URN police response. MotionCam photo series give the ARC operator visual evidence to escalate with confidence.

Beyond intruder: fire, flood and panic on the same app

The same hub also supervises life-safety and property-protection devices: the FireProtect 2 RB (Heat/Smoke/CO) combines heat, smoke and carbon-monoxide sensing in one sealed-battery detector; LeaksProtect sits under sinks and boilers to kill quiet water damage; and the wireless Panic Button covers lone workers and vulnerable residents. For commercial fire detection Ajax now has the dedicated EN 54 Fire Hub Jeweller ecosystem — a separate certified fire CIE covered in our Ajax Fire Hub Jeweller installer guide and the EN 54 hub.

How do you spec an Ajax system, step by step?

Six-step workflow for specifying an Ajax wireless alarm system on a UK site — From walk-round to handover: six steps to a right-first-time Ajax quote.

Walk the site and grade the risk first, then work outside-in: choose the hub (device count, comms paths, groups), map perimeter contacts and glass-break, place motion detection room by room (MotionCam where verification matters), add outdoor detection on approaches, then finish with keypads, sirens and any MultiTransmitter takeover zones. Run the Jeweller signal test from the PRO app at every proposed detector position before you screw anything to a wall, and add a ReX 2 where margin is thin. Finally, enrol the customer on the Ajax app, set groups and scenarios, and hand over with photo verification demonstrated — it sells the maintenance contract for you.

FAQ: Ajax wireless alarms for UK installers

Is Ajax a Grade 2 alarm system?
Yes. The Ajax wireless intruder range carries EN 50131 Grade 2 certification, which suits the overwhelming majority of UK domestic and small-commercial risks.

Does Ajax meet PD 6662:2017 for police response?
Yes — since OS Malevich 2.10 the system supports alarm confirmation, two-stage arming and the other functions PD 6662:2017 requires; configure them in the PRO app and pair with a recognised ARC for URN response.

How many devices can one Ajax hub support?
Hub 2 (2G) and Hub 2 (4G) support up to 100 devices; Hub 2 Plus supports up to 200 devices, 25 groups and adds Wi-Fi as an extra communication path.

What is the real-world Jeweller radio range?
Up to 2,000 m in open space to Hub 2 Plus. Inside UK brick and steel buildings expect far less — always run the in-app signal strength test at each detector position and use ReX 2 extenders where needed.

How long do Ajax batteries last?
Manufacturer-calculated figures are up to 7 years for DoorProtect and up to 5 years for MotionProtect; the app warns well before replacement is due.

Can I connect existing wired detectors to Ajax?
Yes — the MultiTransmitter integrates up to 18 wired zones, so a takeover keeps good existing PIRs and contacts while replacing the panel.

Does photo verification work without mains power or broadband?
Yes. Hubs run on backup battery and dual SIM, and MotionCam photos travel over the Wings radio channel to the hub, then out over whichever comms path is alive.

Can Ajax trigger my CCTV?
Yes — scenarios can link alarm events to cameras and outputs, and most Netview installers run Ajax alongside Hikvision recorders so an alarm pulls up the matching camera view.
