Whenever there is gas fired HVAC equipment in a public space, carbon monoxide detection is a good idea. Carbon monoxide (CO), also called carbonic oxide, is a colorless, odorless and tasteless gas which is slightly lighter than air. It is highly toxic to humans and animals in higher quantities. Carbon monoxide is a common by-product of the combustion (burning) of fossil fuels. Most fuel-burning equipment (natural gas, propane and oil), if properly installed and maintained, produces little CO. The by-products of combustion are usually safely vented to the outside. However, if anything disrupts the venting process (such as a bird's nest in the chimney) or results in a shortage of oxygen to the burner, CO production can quickly rise to dangerous levels.
Monitoring CO is done through a microprocessor based transmitter. It uses an electrochemical gas sensor to detect a variety of gases and then uses that information to ensure safety of the room occupants by disabling the source until it can be properly repaired or serviced. The monitors are maintenance free and stable for long periods of time. Working life is typically 3 years.
