Shop for Electrical . The First Alert SC05CN Combination Smoke Alarm and Carbon Monoxide Detector helps protect you and your famil...y from two deadly threats: fire and carbon monoxide. Fire is a deadly threat to every household; it can strike anywhere, any time. Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Symptoms of carbon monoxide poisoning are like the flu, and you might not even know you're in danger at first. This dual smoke and carbon monoxide alarm is an excellent way to protect your family. The SCO5CN uses an electrochemical carbon monoxide sensor, the most accurate technology available. The alarm uses photoelectric smoke sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. Photoelectric smoke alarms are great for sensing slow smoldering fires quickly. The permanent sensors last the lifetime of the alarm. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The SCO5CN alarm uses different 85-decibel horns and lights depending on whether it's alerting you to smoke or carbon monoxide. A low battery signal alerts you to replace the battery and end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 7-year limited warranty.
