Overview

What it is and how it fits the system.

The Gent 19104-52 is the S4 Mains Powered Interface Unit (Mk 3), a loop-powered mains interface providing sectored zone outputs, auxiliary output and intrinsically-safe detection and alarm capability for the Gent fire alarm system. It operates between Vmin 24V and Vmax 42V, with sector outputs limited to 0.5A each at 24V ±3V and a 0.5A auxiliary output. Protected by dedicated mains, battery and anti-surge fuses with 2.5mm² terminals, it bridges conventional sectored circuits into the Gent loop.

Terminal capacityTerminals 2.5mm²
Mains supply cableMains supply cable must be a standard fire resisting type and should meet PH30 classification; requires a minimum conductor cross sectional area of 0.75mm²
Mains spurMains supply must be via an unswitched 5A fused spur unit; a disconnect device must disconnect both poles with a minimum gap of 3mm
Fail safe operationFail-safe operation is available on all sectored outputs; if loop communications are lost for a defined duration the sector outputs will be turned ON. Sector outputs will turn OFF immediately when communication is restored.
SynchronisationAdjustable synchronisation pulses can be selected for all sector outputs to synchronise the operation of devices such as xenon strobes or speech sounders.
