3. Product Overview

The 05701-A-0330 is a rack-mounted single-channel gas control card for Honeywell Sieger System 57 fire and gas safety systems. It receives raw signals from different types of gas detectors, calculates gas concentration and manages three independent alarm setpoints plus fault monitoring. The front LCD and bar graph provide local concentration readings, while LED indicators show alarm and fault status. Built-in diagnostic routines identify open circuit, short circuit and sensor degradation. It can work with rear relay interface cards such as 05701-A-0326 and 05701-A-0327 to drive local sounders, beacons and shutdown interlocks. It is widely used for toxic and combustible gas monitoring in oil & gas, chemical, refinery and offshore hazardous areas.
