The First Alert SCO5CN Combination Smoke and Carbon Monoxide Alarm features dual sensors to detect both smoke and carbon monoxide in a single device. A photoelectric sensor detects the smoke most often produced by smoldering fires, and minimizes false alarms from cooking smoke or shower steam. Additionally, the advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes. A loud, 85-decibel siren alerts you to the threat; unique alarm sounds and indicator lights on its face distinguish a smoke warning from a carbon monoxide warning.

• Battery operated, so you don't need an electrician for installation
• Provides continuous monitoring of CO levels, even if there's a power failure
• Requiring just two AA batteries and featuring an easy-access battery compartment for quick changes
• Has a single button that allows you to silence a false alarm or test the unit
• Features an electrochemical Carbon Monoxide sensing technology as well as a photoelectric sensor that detects the larger particles of a smoldering fire
• Indicator lights on the face of the unit display the presence of smoke or carbon monoxide, while an 85-decibel siren provides a clear, loud warning upon detection
