Expand detection throughout your home for dangerous carbon monoxide leaks with the First Alert CO400 Battery-Operated Carbon Monoxide Alarm 2-Pack. These carbon monoxide detectors each use 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. Each unit is powered by one 9-volt replaceable battery, offering peace of mind even during power outages, and each includes a permanent internal sensor lasts up to five years. An 85-decibel horn sounds if carbon monoxide levels are too high, and a pull-down action chart on each detector offers guidance on what to do if an alarm sounds. Each unit features a test/silence button that silences the alarm and allows you to test its functionality. No installation or outlet is required, and an optional wall mount is included.
