Overview

What it is and how it fits the system.

The Gent S4-34440-12 is a mains powered interface device for the Nano-panel-based Vigilon addressable loop system. Each unit has a load factor of 1, and up to 32 may be fitted per loop. Where outputs are sectored, a maximum of 8 units per loop applies.

Technical overview

The Gent S4-34440-12 is a mains powered interface device for the Nano-panel-based Vigilon addressable loop system. Designed for integration within the S4 Interfaces & Accessories range, it operates as a dedicated interface unit for addressable fire detection loops powered by the Gent Nano panel. Each unit presents a load factor of 1 on the loop, allowing up to 32 devices per loop under standard configuration, with a reduced maximum of 8 units per loop when outputs are sectored.

This interface supports the Nano panel based Vigilon Nano Panel addressable loop system and loop circuit, with physical wiring and terminal connections specified in the installation instructions. It is compatible with related components including the spare PCB variants VSINTM-PCB02 and VSINTM-PCB12, as well as the lower-capacity S4-34440-02 model. Optional accessories such as the 19104-52 relay and 764744 Zener barrier may be mounted on the unit's DIN rail for extended functionality. For detailed physical connection procedures, users should consult the official installation manual.
