Ajax DoorProtect Plus Jeweller BL – Wireless Opening, Shock & Tilt Detector (Black)

Ajax DoorProtect Plus Jeweller BL is a wireless detector in black, designed for indoor installation on doors, windows, skylights, and vaults. It detects opening, shock, and tilt, providing multi-layered intrusion protection — including when windows are left in airing/ventilation mode. It operates within the Ajax security ecosystem via the encrypted Jeweller radio protocol.
