The DCC Dual Channel Controller is a self contained 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 catalytic
or remote solid state sensor or a remote 4-20 mA transmitter. Other
features include two 4 - 20 mA outputs and one optional 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. An
optional extra loud buzzer is available for noisy environments.
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.
