Ajax KIT2 S (90764.243.BL1) is a complete wireless intruder alarm kit built around the Hub 2 control panel. Designed for small homes and small commercial premises, the kit provides multi-path communications (Ethernet, Wi‑Fi and dual micro‑SIM cellular), encrypted two‑way radio (Jeweller) and support for Ajax’s device ecosystem. The kit supplies both audible local alarms (indoor HomeSiren S and outdoor StreetSiren) and remote notifications via Ajax Cloud and apps.

• Key benefits: reliable multi-path connectivity with automatic failover, large system capacity, tamper protection and support for photo verification when used with MotionCam detectors.
• Use cases: DIY installation for homeowners or rapid deployment by installers for small commercial premises; ideal where resilient communications and remote monitoring are required.
