  • Ajax Fibra MultiTransmitter is a wired integration module that enables the connection of third-party wired detectors, sensors, and devices to an Ajax Fibra security system. Designed for flexibility and professional installations, it allows up to 18 wired zones to be converted into smart devices within the Ajax ecosystem, bringing advanced security automation and remote management to existing setups.
  • Key features include:
  • 18 wired zones for connecting NC, NO, EOL, 2EOL, and 3EOL loops.
  • Individual configuration of each zone in the Ajax app (type of device, room assignment, alarm types, etc.).
  • Event logging with detailed notifications sent directly to users and monitoring stations.
  • 12V power output to supply connected detectors.
  • Built-in tamper protection against opening or sabotage.
  • Remote configuration and firmware updates through the Ajax PRO apps.
  • Reliable communication over Fibra (up to 2,000 m with twisted-pair cable).
  • The MultiTransmitter Fibra helps security professionals modernize and expand existing wired alarm systems, making them compatible with Ajax’s smart features such as scenarios, automation devices, and app-based control
