## Long description

Ajax MultiTransmitter (AJAX-MULTITB) is an interface module that allows integration of wired detectors and sensors into an Ajax wireless security system. Installed in place of an old control panel, the module connects wired devices to the Ajax hub via radio, enabling centralized management and monitoring in the Ajax app while keeping the hub responsible for system stability, security, and firmware updates.
Advantages
MultiTransmitter provides universal compatibility with common wired contact types and supports up to 18 alarm/tamper zones, eliminating the need to replace existing cabling during renovation. The device supplies power to connected detectors, reports alarm types and locations for informative notifications, and works with Ajax hubs and range extenders to extend radio coverage. Installation and setup are simplified through QR-code pairing in the app and automatic checks for incorrect connections.
Suitable for
Retrofitting existing wired alarm systems to Ajax wireless infrastructure
