Why it belongs here

A confident final check before the cart.

Ajax CombiProtect — a two-in-one indoor detector combining PIR motion sensing and acoustic glass break detection in a single compact unit. The Ajax CombiProtect replaces two separate devices with one, mounting on the wall or ceiling to cover both human movement and glass break events in the same zone. The PIR sensor detects motion across a wide angle, while the acoustic sensor listens for the specific frequency pattern of breaking glass up to 9m away. Both sensors operate independently — either can trigger an alarm on its own. Ideal for open-plan rooms with large windows, conservatories, and glazed doors. Communicates wirelessly via Jeweller. Black finish suits modern and dark-toned interiors. A white variant is also available.
