Detailed specifications and benefits
The strength of the KIT18 S lies in the blend of a modern control hub with superior sensors. Below are the key product specifications and the practical benefits they deliver.
- Communications:Ethernet, Wi‑Fi and 2× micro‑SIM (2G/3G/LTE). Benefit: resilient, failover connectivity keeps the system online even if one channel fails — critical for commercial sites and holiday properties where interruptions are costly.
- Device capacity:Supports a large number of wireless devices (model and region dependent). Benefit: scalable for adding sensors, cameras or automation devices as sites grow or requirements change.
- Radio range:Approximately 1.7–2.0 km in open space using Ajax’s Jeweller/Wings protocols. Benefit: good coverage across larger properties, outbuildings and multi‑unit sites without additional wiring.
- Battery backup:Up to around 15 hours typical. Benefit: continued operation through short mains failures.
- Size & installation:Compact enclosure (~163 × 163 × 36 mm) designed for wall mounting; pairs via QR code and uses SmartBracket for quick mounting.
- Detection range:Up to approximately 12 m with ~88.5° horizontal coverage. Benefit: wide coverage zone reduces the number of sensors required in rooms and corridors.
- Pet immunity:Configured for pets up to ~20 kg and ~50 cm height. Benefit: fewer false alarms in pet households without compromising human detection.
- Radio range & battery life:Up to ~1,700 m open space and multi‑year battery life depending on polling intervals. Benefit: long service intervals and flexible placement.
- Sensor type:Superior opening detector with two magnets for reliable status detection.
- Battery:CR123A pre‑installed with up to ~7 years life. Benefit: low maintenance and long replacement cycles.
- Extras:Tamper protection and optional external wired input for connecting third‑party contacts.
- HomeSiren S:Internal siren with tamper protection and remote management through the app for volume and schedule control.
- StreetSiren DoubleDeck:Outdoor siren with a backplate to deliver louder external alarms and visible deterrence.

Benefits in real‑world use
The combination of Hub2 Plus and Superior sensors provides several practical benefits for both installers and end users:
- Fast professional installation:QR pairing and SmartBracket reduce onsite time, useful for installers managing multiple jobs per day.
- Reliable signalling:Dual‑SIM, Wi‑Fi and Ethernet mitigate single‑point failures in communications, maintaining alarm reporting to monitoring centres or end‑user apps.
- Low maintenance:Long battery lifetimes across detectors and remote diagnostics via the Ajax app cut unnecessary site visits.
- Flexible coverage:Strong radio range and scalable device capacity let you secure irregular sites, gardens, outbuildings and multi‑room premises without complex wiring.
Use cases and scenarios where KIT18 S excels
- Family homes with pets:MotionProtect S pet immunities help avoid false alarms while maintaining human detection for corridors, lounges and entryways.
- Small offices and retail outlets:Quick installs, external siren deterrence and remote management suit small‑business needs where downtime must be minimised.
- Holiday lets and secondary residences:Robust multi‑channel reporting and remote app control allow owners to monitor and control security from afar.
- Temporary sites and outbuildings:Wireless range and battery‑powered sensors enable secure coverage without expensive mains wiring or cabling.
- Managed security for landlords:Pre‑bundled kit simplifies standardisation across multiple units and reduces inventory complexity for property managers.
How KIT18 S compares to other solutions
When evaluating the KIT18 S, it helps to look at three broad alternatives: traditional wired systems, consumer DIY smart kits, and other professional wireless kits.
Wired systems can offer dependable permanent connections and do not rely on radio ranges. However, they require more invasive installation work, higher labour costs and limited flexibility for changes. KIT18 S delivers many of the benefits of professional‑grade detection while avoiding expensive rewiring and long installation times.
Lower‑cost DIY systems often prioritise simplicity and price over professional features. They may lack dual‑SIM redundancy, photo verification capabilities and the radio range of Ajax’s Jeweller/Wings protocols. The KIT18 S sits between DIY and enterprise: easier to install than wired professional systems, but with advanced resilience and monitoring features often absent from basic consumer kits.
Other professional kits may match or exceed certain metrics (e.g., proprietary camera ecosystems or different signalling arrangements). KIT18 S differentiates itself with Hub2 Plus multi‑channel redundancy, Superior‑series sensors and a balanced mix of indoor/outdoor sirens plus keypad — a strong out‑of‑the‑box configuration for many small‑to‑medium sites.
Customer feedback and installer observations
Public, attributable customer testimonials for this exact SKU may be limited in reseller listings. Installer and end‑user feedback for Hub2 Plus‑based kits commonly highlights several recurring points:
- Fast setup and pairing through QR codes and SmartBracket mounting make deployment efficient.
- Dual‑SIM and multi‑channel communications give peace of mind, especially in locations with unreliable single‑channel internet.
- Pet‑tolerant detection reduces nuisance alarms in domestic settings.
- Remote diagnostics and app control simplify ongoing management for both installers and property owners.
