Description

The Gent S4-34450 is the four channel low voltage interface for Vigilon and 34000 fire alarm systems. Each channel is configured independently as an input or an output, so one loop address covers up to four circuits. An output gives a normally open or a normally closed set of relay contacts rated 1A at 30V ac/dc resistive, or a 1.5mA 24V dc LED drive. An input can be a fire, fault, supervisory or confirmation input, working on either normally open or normally closed contacts. It takes its power and its address from the loop, includes a loop isolator, and comes with the standard S4 interface spares pack, without an enclosure.
