Gent S4-34450 – 4-Channel Interface I/O Module (PCB Only)

Installation Note: Supplied as PCB only — mounting enclosures are available separately.

The Gent S4-34450 is a loop-powered four-channel interface module designed for seamless integration with Gent Vigilon fire alarm control panels. Providing four independently configurable input/output channels, it allows efficient control of building services and plant equipment directly from the fire alarm system.

Common applications include linking the fire system to sprinklers, security systems, HVAC controls, and door release units, as well as connecting to a zone of conventional detectors. Channel 1 can be configured as a loop-powered zone module, and all outputs are individually sectored for maximum programming flexibility.

The S4-34450 is recognised by the Vigilon panel as a single address, while each input/output channel can have its own unique label displayed on the panel for easy identification. Interfaces can be powered directly from the loop or via a separate mains supply; mains-powered versions include integrated battery backup for added resilience.

Gent S4-34740 Beam Sensor Pair (Transmitter and Receiver) – Excluding Bracket and Base

The S4-34740 Beam Sensor Pair is a high-performance linear beam detection solution for large, open areas where standard point detection isn't practical or is too expensive. This system is perfect for high-ceiling environments like warehouses, atriums, and sports halls. Because it's powered and controlled directly through the loop, it eliminates the need for separate power supplies and helps keep installation costs low.

Featuring advanced one-person alignment and commissioning using integrated auto gain settings, the S4-34740 ensures precise setup with minimal labour. A built-in key-operated test facility allows for easy simulation of fire conditions from ground level, significantly improving maintenance efficiency and safety.

Certified to EN54 Parts 12 and 17, this beam detector integrates seamlessly with Gent Vigilon and Nano fire alarm control panels. Its intelligent software filters minimise false alarms while ensuring rapid fire detection. The unit’s dust-resistant optical lens design also reduces cleaning requirements, further lowering long-term maintenance costs.

Key Features & Benefits

• Loop-powered design supports up to 16 beam pairs per loop.
• Six adjustable sensitivity levels to suit a wide range of applications.
• High resistance to false alarms from sunlight or artificial light sources.
• Remote key-switch testing eliminates the need for high-level access.
• LED array for live signal strength monitoring during commissioning.
• Auto gain settings ensure optimal alignment and ongoing reliability.
• Dust-resistant optics reduce the frequency of maintenance.
• Fully compatible with previous Vigilon beam models using the S-Quad programming base, avoiding software upgrade requirements.

Compliance & Standards

• EN54-12: Linear Beam Smoke Detectors
• EN54-17: Short Circuit Isolators
• CE and UKCA approved
