SCC Self Contained Controller combines toxic and/or combustible gas detection with basic control functionality for non-hazardous, non-explosion rated, commercial applications. 

Available in one or two channel configurations for monitoring toxic and/or combustible gas types by means of an integral electrochemical Carbon monoxide (CO) or Nitrogen dioxide (NO2) sensor and one of three remote catalytic combustible sensors used to detect Hydrogen (H2), Propane (C3H8) or Methane (CH4). Monitoring of CO or NO2 may also be achieved remotely by combining the SCC with a 4 – 20 mA transmitter such as the LPT-TCO or LPT-END.

The SCC also features two alarm level line voltage relays with field configurable time delays and trigger levels, field selectable integral audible alarm and an LED panel indicating power, channel alarm status and fault conditions. Automated calibration and other maintenance procedures are simple and easily performed in the field, and our proprietary Calibration Extending Firmware (CEF) takes into account the aging of the toxic sensors so that less frequent calibrations are required in less-critical applications such as parking garages.

The SCC comes standard with a water / dust tight, corrosion resistant ABS / polycarbonate enclose with a hinged, secured door. With the optional, factory installed splash guard, the enclosure is IP54 rated and protect in water spray or wash down applications.
