CHCO – Natural Gas & Carbon Monoxide Detector

Application

Suitable for natural gas and carbon monoxide detection in domestic applications.

Description

The Duomo CHCO detects the presence of natural gas and carbon monoxide using dual sensor technology. It is a fixed, wall-mounted system with a permanently connected 230 V electrical supply.


The CHCO is fitted with an output function for triggering ancillary devices, for example a gas shut-off valve. In homes equipped with gas appliances, the output signal can trigger a shut-off valve on the incoming mains gas pipe. Such a valve should require a manual action for resetting to the open position EVRM valves. For CO detection, in addition to the shutdown of the incoming gas supply, the CHCO can also start a ventilation fan.
