3. Product Overview

The 0571-A-0328 is a rack-mounted triple relay interface card for Honeywell Sieger System 57 fire and gas safety systems. It is installed behind the gas control card to provide three separate SPCO relay outputs for alarm and fault logic. Each relay channel can be individually configured as latching or non-latching to match site shutdown, pre-alarm and fault sequences. Independent front LEDs show energized status for quick visual inspection during routine checks. The relay contacts can drive sounders, beacons, shutdown interlocks and remote alarm panels. It offers flexible multi-stage alarm logic for toxic and combustible gas monitoring in oil & gas, chemical, refinery and offshore hazardous areas.
