Four-channel relay with potential-free contacts to control power supply remotely
Product is not available in your region
Advanced automation for greater safety
MultiRelay Fibra is a relay module designed to implement complex wiring diagrams. It has four relays with potential-free (dry) contacts that can control four separate circuits independently. MultiRelay can integrate various appliances, electrical mechanisms and even third-party security devices into the Ajax system. With Ajax scenarios, the module provides fully automated actions in response to alarms and security mode changes or performs them by a specified schedule.
Key features
MultiRelay Fibra is a device of the wired Fibra product line. Only accredited Ajax Systems partners can sell, install, and administer Fibra products.
Remote power supply control
Smart security and comfort
Use automation scenarios to make life safer and more comfortable. Set your office lights to turn off automatically on arming. Program your projectors to turn on when outdoor motion detectors identify intruders. Or turn on your toaster at a certain time in the morning.

One multi-purpose casing
The convenience for PROs is a big priority, so Ajax products are always thought out to every detail, hence easy to work with. That’s why we created Case, a one-stop casing suitable for module-type Fibra devices. Various size options facilitate combining multiple modules, optimizing space and reducing installation expenses. MultiRelay is compatible with Case2 and can be installed in a single casing with other devices.

Fibra
Unique wired technology
The Ajax system uses secure two-way communication based on the Fibra proprietary protocol. It features encryption and device authentication to prevent sabotage, spoofing, or data theft. Fibra lines are multifunctional and support connecting different types of devices to one line: sirens, keypads, and detectors with photo verification.
![Fibra](/api/cdn-img/?img=%2Fupload%2Ffibra_md_66fa900d1c%401.jpg&1689690542)
Up to 2,000 m1 of wired communication with a hub
One line for different types of devices
Protection against sabotage and spoofing
Energy efficiency as a priority
Fibra communication requires minimum power consumption: the module consumes only up to 0.18 W at its peak. Fibra also follows the TDMA principle. Each device has a short time frame to exchange data with a hub, and its communication module is inactive the rest of the time. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.

PRO is king
The myth about wired systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for PROs by developing an ultimate set of tools to make the process easy and flexible, from project design to client support and system maintenance. The module is installed inside Case with only one move of the hand. Intuitive Ajax apps help quickly make the device a part of the system, and each device can always be reconfigured remotely without site visits. No need for programmers — everything is available out-of-box.
Fibra power supply calculator
The online tool provides security specialists with comprehensive information about the devices’ power consumption. It's easy to check before installation whether the wired system project will work in practice. The calculator allows real-time project-making, highlighting the problem areas and offering solutions. Once the calculations are finished, the results can be downloaded as a PDF file.
The module needs to be installed into Case. The installation kit includes all the necessary fasteners. The casing has holders for device placement which are flexible and require only one move of hand to install the module inside. A built-in spirit level and slightly bigger fixing points assist the professional in a perfectly accurate mounting position. Inside, Case has special fasteners for cable management and several perforated parts on the sides and back for wiring out cables. Markings for drill positioning and special protectors inside help to stop the drill before it hits holders or other components. The top lid of the casing is equipped with anti-falling screws to prevent accidental dropping of installation parts.

The device is paired with the hub automatically via Fibra line scanning. This tool is available in the desktop or mobile PRO apps. An installer only needs to name the device and assign it to the room and security group. The device can also be added by scanning the QR code or entering its ID manually.
