What is the role of a carbon monoxide detector in a home with combustion appliances?

The primary role of a carbon monoxide detector in a home with combustion appliances is to warn occupants of the presence of carbon monoxide (CO), a colorless, odorless gas that can be deadly. Combustion appliances, such as furnaces, water heaters, and gas stoves, can produce carbon monoxide if they are malfunctioning or not properly ventilated.

The detector continuously monitors the air for CO levels and emits an alarm when it detects concentrations that could be harmful. This function is critical, as early detection of carbon monoxide can prevent poisoning and save lives.

In contrast to this role, a detector does not provide lighting in emergencies or measure energy consumption, nor does it assess the physical condition of appliances. The emphasis on detecting carbon monoxide and ensuring the safety of occupants highlights its importance in homes utilizing combustion appliances.
