Product information

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
  • Connecting IR barriers, gas, temperature, liquid level detectors and other wired sensors
  • Sites where centralized app-based management and remote alarm notifications are required

  • Weight: 805 g
  • Color: black
  • Number of alarm/tamper zones: 18
  • Supported contact types: NO, NC (without R), EOL (NC with R), EOL (NO with R)

  • Radio band: 868.0–868.6 MHz or 868.7–869.2 MHz (region-dependent)

  • Warranty: 24 months (batteries not covered)

How to use

Install the MultiTransmitter board in the enclosure and connect the module to the Ajax hub by scanning the QR code in the Ajax app. Wire the existing detectors to the specified alarm/tamper zone inputs and connect the main and backup power sources according to the user guide. Configure each wired device in the app: assign a device type and room to enable detailed notifications and correct reporting to monitoring stations. If using MotionCam, connect it to enable photo verification on motion-triggered alarms when the system is armed.

Usage recommendations

Place the hub and range extenders to ensure reliable radio communication with the MultiTransmitter; verify detector wiring with the app’s automatic checks; use the app to assign alarm types and locations for clearer notifications and to enable monitoring station codes as required.
