What is Ajax MultiTransmitter?

Ajax MultiTransmitter is an integration module that connects compatible third-party wired detectors to an Ajax security system. It supports up to 18 wired zones, runs on a 4 Ah or 7 Ah backup battery during power outages, and includes tamper protection against opening or removal. Connected detectors get individual names, rooms, and alarm types in the Ajax app, plus access to automation, expansion, and professional monitoring. Device reuse is not automatic: wiring, contact types, power requirements, and detector condition must be verified by a professional installer.
