CO alarm technologies

Carbon monoxide (CO) alarms detect this colorless, odorless gas produced by incomplete fuel burning. They typically use electrochemical sensors or metal oxide semiconductor sensors to monitor CO levels continuously. When CO concentration exceeds safe limits, the alarm sounds, warning occupants to ventilate and evacuate. These devices are essential safety tools in homes with fuel-burning appliances, fireplaces, or attached garages, providing early detection to prevent poisoning. Proper placement, regular testing, and maintenance ensure reliable operation, making CO alarms a critical safeguard against the unseen hazard of carbon monoxide exposure.
