Combined CO and Gas Alarm

The Duomo CHCO is a dual sensor, Gas and Carbon Monoxide Detector. When Gas and/or Carbon monoxide are sensed the detctor sounds an on board audible alarm and change over a volt free contact relating to the type of gas sensed. These relays can be used to isolate the electrical supply to Gas solenoid valves or give a remote indication of an alarm.The alarm threshold for Gas is 20%LEL and for Carbon Monoxide 300ppm. The CHCO also has a seperate CO relay alarm facility which gives a relay output at 30-50-100ppm Carbon Monoxide based on Time Weighted Average function.
