Description

A comprehensive and dependable, self-contained system that offers one or two channel configurations for monitoring toxic and combustible gases and PID TVOCs with straight-forward control functionality for non-hazardous, non-explosion rated, commercial and light industrial applications. Sensor configurations include, two internal electrochemical sensors (one must be CO), or one internal electrochemical and one remote catalytic or PID sensor or a remote 4-20 mA transmitter.

Field configurable settings are done through an easy to navigate, comprehensive menu structure. Other features include two 4 – 20 mA outputs or jumper configurable 0-10v / 2-10v output that can be used for VFD control, one configurable 4 – 20 mA input, two alarm level line voltage, two SPDT dry contact relays with field configurable time delays and trigger levels, a field selectable integral audible alarm and an LCD display with LED indicators for channel alarm status and fault conditions.

Automated calibration and other maintenance procedures are simple and easily performed in the field. For parking garage applications, our proprietary Calibration Extending Firmware (CEF) takes into account the aging of the toxic gas sensors so that less frequent calibrations are required.
