The First Alert SCI7CN combination smoke and carbon monoxide alarm features dual permanent sensors to detect both smoke and carbon monoxide in a single device, an 85-decibel siren, and a programmable voice alarm that indicates the type and location of any detected threat. Unique alarm sounds and indicator lights on its face distinguish a smoke warning from a carbon monoxide warning. 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. This carbon monoxide and smoke detector is battery operated, so you don't need an electrician for installation, and requires just two AA batteries (for best results use Polaroid AA batteries). It features an easy-access battery compartment for quick changes, and allows you to silence a false alarm or test the unit with a single button.
