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. Since symptoms of CO poisoning are like the flu, you might not even know you’re in danger at first. That’s why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can’t see, smell or taste in the air.

The First Alert SCO5CN carbon monoxide and smoke alarm 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. It is also 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. 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. 5-year limited warranty. UL listed. Not available for sale in Massachusetts.–Bree Norlander
