Ajax Superior MultiTransmitter IO (4X4) Fibra Wired Integration Module

Ajax Superior MultiTransmitter IO (4X4) Fibra Wired Integration Module

The Ajax Superior MultiTransmitter IO (4X4) Fibra is a wired integration module built for the Ajax Superior product line, giving installers four inputs and four outputs to bring third-party wired security and automation equipment into a single, unified Ajax system. It is purpose-built for demanding or non-standard installations where legacy detectors, locks, or electrical devices need to work alongside modern Ajax hardware, all managed and monitored through the Ajax app and PRO tools.

Key Features

• Four configurable inputs supporting NC, NO, EOL, 2EOL, 3EOL and roller-shutter connection types for maximum compatibility with existing detectors.
• Four outputs in total — two potential-free relay outputs for switching sirens, strobes and other appliances, plus two logical outputs for door locks and blocking elements.
• Supports up to eight third-party devices connected simultaneously across the module's inputs and outputs.
• Fibra wired protocol with two-way, encrypted communication using a dynamic key to guard against interception and spoofing.
• Long cable runs of up to 2,000 metres over standard U/UTP Cat.5 twisted-pair cable.
• Auxiliary power output of 11.6–12.4 V DC, up to 500 mA, for powering connected third-party devices.
• Unavoidability-principle door protection (Zwangsläufigkeit), ideal for markets and sites requiring strict door-locking sequences.
• Remote configuration and control of connected equipment, event types, and automation scenarios directly from Ajax apps.
• Tamper and malfunction monitoring, including detection of communication loss, lid tampering, and wiring faults.

Typical Use Case

This module suits small and medium commercial or residential projects where existing wired detectors, panic buttons, bolt locks, or sirens are already in place and need to be modernised without a full equipment replacement. For example, a retail store with older motion and door detectors can connect them through the MultiTransmitter IO (4X4) Fibra to gain Ajax-level notifications, remote arming/disarming, and automation scenarios, while also controlling door-locking hardware on the unavoidability principle. Because it is part of the Ajax Superior range, it is best suited to installations requiring certified, high-security-grade components.
