What is Superior MultiRelay Fibra?

Superior MultiRelay Fibra is a wired four‑channel relay module that allows automation of external devices such as gates, locks, lighting, shutters, and other low‑voltage circuits within an Ajax Fibra system.

How many outputs does MultiRelay Fibra have?

It includes four independent relay channels, each configurable for pulse or bistable operation.

What is the communication range on Fibra?

Fibra wired communication supports distances up to 2,000 metres using U/UTP Cat.5 cable.

Does MultiRelay Fibra support automation scenarios?

Yes. Each relay can be controlled manually or through Ajax automation scenarios, including schedule‑based actions, security mode changes, and reactions to detector events.

What types of loads can it switch?

Each relay channel is a dry contact output suitable for low‑voltage control circuits. It does not supply power to the load and must be used to switch external circuits within their rated limits.

Does it include anti‑sabotage protection?

Yes. It includes a tamper alarm, device authentication, short‑circuit protection, and communication loss detection.

Can MultiRelay Fibra be configured remotely?

Yes. All relay settings, scenarios, and channel modes can be configured remotely through Ajax PRO apps on desktop or mobile.

Which hubs is it compatible with?

Superior MultiRelay Fibra is compatible with Ajax hubs that support Fibra devices, such as Hub Hybrid (2G/4G).

Superior MultiRelay Fibra

A four‑channel dry‑contact relay module designed for advanced automation within Ajax Superior security systems. MultiRelay Fibra provides independent control of four circuits, supports bistable and pulse modes, and communicates with the hub over long‑range encrypted Fibra wired technology. With robust anti‑sabotage protection and flexible installation options, it is ideal for professional‑grade automation in commercial, industrial, and high‑security environments.

Key Features

Four independent dry‑contact relays for multi‑zone automation
Bistable or pulse operation with adjustable pulse duration (1 s to 2 h)
Up to 2,000 m Fibra communication with encryption and authentication
Low power consumption (up to 185 mW)
Temperature protection — all relays open automatically at +85°C
State stability option preserves relay states after power loss
Supports automation scenarios for alarms, schedules, mode changes, and environmental triggers
Compatible with Case2 enclosures for tamper protection and clean wiring

How It Works

Superior MultiRelay Fibra connects to the Ajax Fibra line and provides four potential‑free relay outputs for controlling external devices. Each relay can be configured independently, allowing installers to automate lighting, gates, valves, HVAC equipment, access control systems, and other electrical circuits.

The module supports:

Bistable mode — toggles state on each activation
Pulse mode — activates for a defined duration (1 second to 2 hours)
NO/NC contact configuration
State retention after power outages (optional)

All communication with the hub is encrypted, and the system continuously polls the device to ensure real‑time status updates.

Installation & Setup

Powered directly from the Fibra line (8.5–26 V DC)
Install inside a Case2 enclosure (recommended) for tamper protection
Supports U/UTP cat.5 cabling up to 2,000 m
Pair with the hub via QR code or automatic line scanning
Configure relay modes, pulse duration, and automation scenarios in Ajax apps

The module can be installed behind any Fibra device, inside electrical panels, or in structured wiring enclosures.

Reliability & Supervision

MultiRelay Fibra includes multiple layers of protection:

Tamper alarm (when installed in Case2)
Short‑circuit protection
Overheating protection — relays open at +85°C
Encrypted two‑way communication
Connection loss detection within 36 seconds

Fibra ensures stable, interference‑free operation even in electrically noisy environments.
