Be alerted to dangerous carbon monoxide leaks with the First Alert CO410 Battery-Operated Carbon Monoxide Alarm with Backlit Digital Display. This carbon monoxide detector uses an electrochemical carbon monoxide sensor, the most accurate CO detection technology available, to detect the CO you can’t see, smell, or taste in the air. An easy-to-read backlit digital display allows a quick view current and peak CO levels. This unit is powered by two replaceable AA batteries, offering peace of mind even during power outages. An EZ access battery door allows you to change out batteries without having to dismount the alarm. An 85-decibel horn sounds if carbon monoxide levels are too high, and a test/silence button silences the alarm and allows you to test its functionality. No installation or outlet is required, and an optional wall mount is included.
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 CO410 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. This alarm is perfect for bedrooms, hallways, and basements. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. It is powered by two AA replaceable batteries giving you peace of mind during power outages. The test/silence button both silences a non-threatening alarm and low battery warning and allows you to test the unit’s functionality. The alarm performs its own internal test as well. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. No installation is required and the attractive design allows the unit to be placed anywhere you need it. It includes an optional wall mount–no outlet required. An audible and visual low battery signal alerts you to replace the battery. UL listed. –Bree Norlander
