Ajax Transmitter Fibra Wired Integration Module for Third-Party Detectors

Ajax Transmitter Fibra – Wired Integration Module

The Ajax Transmitter Fibra is a compact interface module that lets installers bring almost any third-party wired detector or accessory into an Ajax security system. Rather than replacing existing hardware, it sits inside the housing of a compatible wired device and relays its signals to an Ajax hub over the secure Fibra wired protocol, giving legacy or specialist equipment a place in a modern, app-controlled security ecosystem.

Key Features

• Universal wiring support for NC, NO, EOL, 2EOL and 3EOL detector connection types, covering most third-party alarm loops.
• Dual input terminals (Z1 and Z2) allowing a single device to be wired using an AATT (Alarm-Alarm-Tamper-Tamper) scheme, or two separate devices on one module.
• Encrypted two-way Fibra communication with a dynamic key, designed to resist interception, spoofing and line tampering.
• Regular status polling so the hub is quickly alerted if the module loses contact or a fault occurs.
• Remote configuration through the Ajax PRO app, removing the need for repeat site visits to adjust settings.
• Compact footprint engineered to fit inside the enclosure of the connected third-party device rather than requiring a separate box.
• KeyArm Zone capability, enabling a connected wired accessory such as a keypad or button to arm, disarm or switch modes on the Ajax system.
• Power output for the connected device, removing the need for a separate power supply in most installations.

Typical Applications

The Transmitter Fibra is aimed at installers upgrading a site that already has wired detectors, roller shutters, panic buttons, or access devices in place. Instead of ripping out functioning hardware, the module bridges it into the Ajax hub, extending the life of existing equipment while adding smartphone control, instant alerts, and centralised monitoring. It also suits situations where a specific detector type is not yet available in the native Ajax product range, letting integrators fill that gap with a trusted third-party sensor.

Frequently Asked Questions

Can any third-party detector be connected?
Most wired detectors using standard NC, NO or EOL-style outputs can be integrated, though installers should confirm the specific device's electrical characteristics are within the module's supported range.

Does the module need its own enclosure?
No. It is designed to be small enough to fit inside the housing of the wired device it is paired with, avoiding extra visible hardware.

Who can install this device?
Fibra integration modules are intended for installation by trained security professionals familiar with the Ajax Fibra wired protocol and system configuration.
