The Combination Smoke and Carbon Monoxide Alarm features a photoelectric sensor that detects the smoke most commonly produced by smoldering fires, providing sensitive detection while minimizing false alarms from cooking smoke or shower steam.

Unique alarm sounds and indicator lights on the face of the detector distinguish a smoke warning from a carbon monoxide warning.
