The DCC Dual Channel Controller is a self contained gas detection system that offers one or two channel configurations for monitoring toxic, combustible and refrigerant gases with straightforward control functionality for non-hazardous, non-explosion rated, commercial applications.
Sensor configurations include, two internal electrochemical sensors (one must be CO), or one internal electrochemical and one remote sensor (catalytic, solid state or a remote 4-20 mA transmitter). Field configurable settings are done through an easy to navigate, password protected menu structure.
Standard features include two 4 – 20 mA outputs and one configurable 4 – 20 mA input, two alarm level line voltage relays with field configurable time delays and trigger levels, a field selectable integral audible alarm and an LCD/LED panel indicating channel alarm status and fault conditions. Optional value added, factory installed features include, a top mounted strobe, an extra loud, door mounted buzzer for noisy environments or a door mounted, water tight buzzer and splash guard for wet environments and an internal enclosure heater for cold environment applications.
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.
