Description

The DCC-SD is a self-contained, single sensor, sample draw monitoring system that is designed to draw samples of air from hard to access locations such as shafts, tall ceilings, wells, pits, small rooms and many other locations where it is difficult to install gas detectors. The DCC-SD provides continuous sampling of target air over long periods of time.

The DCC-SD system is designed to be installed outside the target location, at a viewable height, with sample tubing running from the monitoring system to the sampled environment. The sample draw pump pulls air from the area through the tubing, in through the inlet port and over the sensor. The air is then exhausted through the outlet port. If the gas readings are higher than a specified set point, the DCC-SD will go into alarm.

The DCC-SD can be configured with a toxic, combustible or refrigerant sensor and comes with a flow detector, a sample draw pump and an internal adjustable flow meter. Features include one configurable 4 - 20 mA output, one alarm level line voltage relay with field configurable time delays and trigger levels, a blocked flow alarm indicating a dirty filter or clogged tubing, a side mounted audible buzzer and an LCD display with LED indicators for channel alarm status and fault conditions.

The filter should be replaced with it becomes dirty and the tubing should be checked regularly to ensure it remains unblocked. The device has been factory tested with a maximum of 15.24 m / 50 ft of sample tubing. For the best response, the sample tubing between the sample point and the inlet port should be kept as short as possible.

Caution: The DCC-SD sample draw system should not be used inside classified hazardous areas or to sample draw combustible gases because the pump is not intrinsically safe.
