Ajax Superior vs Baseline: Which Alarm Kit Should You Choose? (UK Buyer's Guide)

Ajax's Superior line (Fibra-wired capable, Grade 3-equivalent detection) suits larger homes, commercial premises and anyone who wants the longest sensor range and a wired backup option. Ajax's Baseline line (Jeweller wireless only) suits a standard house or flat where an easy, drill-free wireless install matters more than commercial-grade range. Vertex Supplies stocks both lines in full: 196 Superior products and 256 Baseline products, including matching numbered kits (Kit 1 through Kit 27) for either line.

Quick recommendations

• Best Superior kit for a larger house: Ajax Kit 21 S. Hub 2, MotionProtect S, DoorProtect S, Keypad Plus S and StreetSiren DoubleDeck S in one bundle.
• Best Baseline kit for a standard house: Ajax Kit 2. The same core coverage (hub, motion, door contact, siren) on the Jeweller wireless protocol.
• Best Superior hub: Ajax Superior Hub Hybrid (2G) (8PD). Supports Fibra wired devices as well as wireless, which helps if you want a wired backup on key sensors.
• Best Baseline hub: Ajax Hub Hybrid 2G 8PD-ECG. The wireless-only equivalent at lower cost, with the same app and monitoring.

What separates Superior from Baseline

Ajax names its product lines Superior and Baseline. The split is real, not a price-tier label. The core differences:

• Wired option: Fibra, Ajax's wired sensor protocol, is exclusive to the Superior line. If you want any device hard-wired, for reliability in a detached outbuilding or where you do not want batteries, choose a Superior device.
• Range and detection grade: Superior devices offer longer wireless range. Ajax positions them for larger properties and commercial installs. Baseline (Jeweller protocol) covers a standard semi or terrace comfortably with a shorter rated range.
• Price: Superior devices generally cost more. A Superior hub or sensor typically sits above its Baseline equivalent, reflecting the wired capability and extended range hardware.
• Naming: every Superior product carries "Superior" in its name (for example "Ajax Superior MotionProtect Plus"). A product name without Superior means Baseline.

Which kit number should you buy

Ajax numbers its bundled kits (Kit 1, Kit 2, Kit 5, up to Kit 27) by the combination of hub, detectors, control method (keypad or key fobs) and siren type. The number does not show Superior or Baseline. Vertex stocks matching kit numbers in both lines, so the "S" suffix (for example Kit 21 S) marks the Superior version of the same combination. Want Baseline coverage with a specific control and siren combination? Look for the same kit number without the S.

Mixing lines does not work

Know one point before you buy. Superior and Baseline devices do not interoperate on the same hub type as you might expect. A Baseline (Jeweller) hub does not run Fibra wired Superior sensors, and you cannot mix Fibra wired devices onto a Baseline-only hub. Decide which line you need before you buy individual sensors to add to a kit.

DIY or professional install

Both lines pair with the same Ajax app and support DIY self-install. Neither line requires a monitoring subscription, which is one reason people recommend Ajax as an alternative to subscription-locked systems like Verisure or ADT. A wired Fibra sensor run by a professional needs a separate quote, since the job involves cabling instead of a stick-on wireless sensor.

Summary: Superior and Baseline in one line each

Superior: wired Fibra option, longer range, higher spec, higher price, aimed at larger or commercial properties. Baseline: wireless only (Jeweller), shorter range, lower price, suited to a standard house or flat. Vertex Supplies stocks both lines in full, including matching numbered kits, so you specify the exact combination of devices you need instead of settling for a fixed bundle.
