What is Ajax MultiTransmitter?

Ajax MultiTransmitter Jeweller connects compatible third-party wired detectors to an Ajax security system and supports up to 18 wired zones. It can use a compatible 12 V backup battery, purchased separately. Ajax recommends 4 Ah or 7 Ah batteries; runtime depends on the battery and connected load. Its battery does not provide backup power for the hub. Connected zones receive individual names, rooms, and alarm types in the Ajax app. Wiring, contact types, power requirements, detector condition, and monitoring compatibility must be checked by a professional installer.
