Ajax KIT 5 S Wireless Intruder Alarm Kit — Hub 2 Plus, 2× MotionProtect S, DoorProtect S, KeyPad Plus S, StreetSiren, HomeSiren S — 90770.246.BL1

Introduction to the Ajax KIT 5 S and its key features

The Ajax KIT 5 S (90770.246.BL1) is a pre‑configured wireless intruder alarm kit centred on the Hub 2 Plus control panel. Designed for homes, apartments and small commercial sites, this kit bundles the essential sensors and sirens you need for a fast, reliable security installation: two MotionProtect S motion detectors (with anti‑masking and pet immunity), a DoorProtect S door/window sensor, a KeyPad Plus S for user control, an indoor HomeSiren S and an outdoor StreetSiren. The Hub 2 Plus provides resilient communications (Ethernet, Wi‑Fi and dual SIM/LTE), encrypted two‑way radio (Jeweller) and Wings photo verification so you can confirm alarms with images.

• Four‑channel communications:automatic switching between Ethernet, Wi‑Fi and two LTE SIMs for uninterrupted connectivity.
• Photo verification:Wings protocol delivers up to five photos per event (up to 640×480) so remote users or an alarm receiving centre can verify incidents quickly.
• Professional capacity:supports up to 200 wireless devices and 200 users — suitable for professionally installed residential and small business systems.
• Anti‑tamper and anti‑masking:MotionProtect S includes anti‑masking and pet‑immune detection, reducing false alarms from pets or obstruction attempts.

Detailed specifications and benefits

The KIT 5 S combines thoughtfully matched components to deliver broad coverage and practical functionality. Below is a concise breakdown of the key specifications and the benefits they provide in everyday use.

• Hub 2 Plus:163 × 163 × 36 mm control panel with built‑in Li‑ion 3 Ah backup battery (approx. 15 hours runtime), Ethernet (100 Mbps), Wi‑Fi (802.11 b/g/n) and two micro‑SIM slots supporting LTE. Benefit: robust connectivity with automatic channel priority ensures the system stays online even if one path fails.
• MotionProtect S (×2):Passive infrared detectors with anti‑masking and pet immunity. Benefit: reliable motion detection without nuisance alarms from pets and resistance to deliberate obstruction attempts.
• DoorProtect S:Magnet contact for doors and windows for fast, low‑profile intrusion detection.
• KeyPad Plus S:User keypad with built‑in siren for convenient arming/disarming and user access control.
• HomeSiren S & StreetSiren:Indoor and outdoor sirens provide audible deterrence and neighbourhood alerting.

• Capacity:up to 200 wireless devices, up to 200 users, up to 50 rooms/zones and up to 100 IP cameras (RTSP). Benefit: scales with most residential and many small commercial needs.
• Radio protocols:Jeweller (events) and Wings (photo). The Jeweller radio provides encrypted two‑way signalling and configurable polling intervals (12–300 s) to balance responsiveness and battery life.
• Range:open‑field device range typically up to ~1,700–2,000 m (environment dependent). Benefit: flexible sensor placement, including detached outbuildings or large properties when conditions permit.

• Wings photo verification:up to five photos per series at resolutions up to 640×480 with delivery times typically under ~9 seconds when using Wings + LTE. Benefit: quick visual context for an alarm event, reducing false dispatches and enabling faster, more informed responses.

• Power:110–240 V mains with built‑in Li‑ion backup in the Hub 2 Plus. Benefit: continuous operation during mains interruptions for a limited period.
• Operating conditions:Hub indoor rating IP20, operating range −10°C to +40°C and up to 75% humidity. Follow supplied manuals and local alarm regulations for professional installations.

Use cases and scenarios where the KIT 5 S excels

The Ajax KIT 5 S is ideal where dependable, rapid deployment security is required without the complexity of custom system design. Typical scenarios include:

• Family homes and apartments:Pre‑configured sensors cover typical entry points and living spaces. Photo verification reduces false alarms and gives homeowners confidence when away.
• Small retail outlets and offices:The kit provides perimeter and interior detection with outdoor siren deterrence and quick verification for staff or monitoring centres.
• Rental properties and holiday lets:Remote management through Ajax apps and photo verification allow property managers to respond to incidents without on‑site visits.
• Sites with unreliable internet:Dual‑SIM LTE plus Ethernet and Wi‑Fi ensure continuity where single‑channel solutions fail. Ideal for locations with intermittent broadband or where redundancy is mandated by an alarm receiving centre.

How the KIT 5 S compares with similar solutions

There are three broad categories of competing security options: basic DIY kits, traditional wired professional systems, and other high‑end wireless professional solutions. The AJAX KIT 5 S positions itself between DIY simplicity and professional capability.

Many entry‑level DIY alarms offer simple motion and door sensors with basic app alerts. The KIT 5 S differs by offering higher signal range, encrypted radio protocols, photo verification, professional device capacity and multi‑channel communications. Result: fewer false alarms, better resilience and suitability for monitored installations.

Wired systems excel in permanence and often integrate with building automation, but they require disruptive cabling and higher installation cost. The KIT 5 S delivers near‑professional performance with fast, non‑intrusive wireless installation and easy reconfiguration — attractive where cabling is impractical or speed of deployment matters.

Compared with other professional wireless kits, the Hub 2 Plus stands out for its Wings photo verification and four‑channel communications. Many competitors may offer LTE backup or photo verification as add‑ons, but Ajax integrates these features and a large device/user capacity as standard, making it a compelling choice for installers who want a robust, future‑capable platform.

Customer testimonials and sample reviews

Below are anonymised, representative impressions from users who value reliability, verification and ease of use (sample quotes for illustrative purposes):

• Homeowner, UK:"We installed the KIT 5 S after a spate of break‑ins locally. The outdoor siren is loud, and the photo alerts on my phone gave me peace of mind — I could see immediately whether it was a delivery or a real alarm."
• Small shop owner:"The dual SIM support meant the system stayed online during a broadband outage. Motion detection with pet immunity also cut out the false alarms we used to get from the cat."
• Installer, regional security firm:"Clients like the professional feel of the Hub 2 Plus and the ability to expand with cameras and sensors. Photo verification helps operators reduce unnecessary call‑outs."

Note: these are anonymised, typical user summaries rather than verbatim endorsements from identifiable individuals.

Practical considerations and documentation

Although the KIT 5 S is designed for rapid deployment, professional installation is recommended for monitored sites and where compliance with alarm receiving centre (ARC) requirements is required. Ajax publishes comprehensive manuals for each device — installers should consult the Hub 2 Plus, MotionProtect S, DoorProtect S, KeyPad Plus S, HomeSiren S and StreetSiren manuals for configuration, radio band settings and best practices. Also note: the provided stock information shows 0 units — confirm lead times with suppliers before marketing or quoting installations.

Conclusion: why the Ajax KIT 5 S is a great choice

The Ajax KIT 5 S (Hub 2 Plus) strikes a strong balance between DIY convenience and professional capability. It combines secure encrypted radios, multi‑channel communications, Wings photo verification and a scalable device capacity into a single pre‑configured kit that works well for homes, small businesses and managed properties. Where reliability, quick visual confirmation and flexible communications are priorities, this kit delivers tangible benefits: fewer false alarms, reduced unnecessary responses, and a robust online presence even if a primary network fails.

For anyone seeking a modern, expandable intruder alarm that can be installed quickly and grow with future needs, the Ajax KIT 5 S is a compelling option. Check the official manuals for technical details and confirm current stock and lead times with your supplier before purchase.
