The Duomo CHCO Combined Carbon Monoxide & Natural Gas Alarm provides dual detection to protect homes, offices and commercial environments from methane leaks and carbon monoxide (CO) poisoning.
With catalytic and electrochemical sensors, this unit monitors both gases accurately. If dangerous levels are detected, a loud audible alarm and volt-free SPDT relays activate, allowing connection to gas solenoid valves or remote indicators for added safety.
Built to EN50194 (gas) and EN50291 (CO) standards, the Duomo CHCO is compliant, reliable and worry free.
Features
Dual Detection – Monitors natural gas (methane) and carbon monoxide.
Microprocessor Control – Accurate readings, reliable operation and fast response.
SPDT Alarm Relays – Separate SPDT relays for gas and CO alarms, for connection to safety shut-off valves or external alarms.
High Quality Sensors – Catalytic sensor for methane detection and electrochemical sensor for CO monitoring.
Alarm Setpoints – Gas: 10% LEL | CO: 300ppm, with additional relay outputs at 30, 50 and 100ppm CO (time-weighted average.
Visual Sensor Active Indicator – Confirms continuous monitoring and system ready.
Easy Power Integration – 230V supply.
