Monitoring device for safety shutdown of the boiler in case of carbon monoxide leakage. Alarm threshold: 50 ppm CO according to DIN EN 50 291-1
This device is designed to protect people from the topical effects of carbon monoxide contact. Lifetime CO sensor max: approx. 6 years (max. 40°C, min. 40% rH), approx. 10 years (max. 28°C, 30% rH).
Important warnings:
The following substances can influence the CO detector and possibly trigger a false alarm. Therefore, they must not be used in the room where CO detector is installed: ethylene, ethanol, alcohol, iso-propanol, gasoline, toluene, ethyl acetate, hydrogen, hydrogen sulfide and sulfur dioxides. Individuals with specific medical conditions may not be adequately protected by the CO detector and should use a warning device that produces audible and/or visible signals at carbon monoxide concentrations as low as 50ppm. If in doubt, consult a physician.
