New Duomo Combined Carbon Monoxide and Gas Alarm

The 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 changes 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 to give a remote indication of an alarm.
