Protect your home from dangerous carbon monoxide with the First Alert CO400 COBATT-6 Battery-Operated Carbon Monoxide Alarm 6-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 includes a permanent internal sensor that lasts up to five years. An 85-decibel horn sounds if carbon monoxide levels are too high, and a pull-down action chart on the detector offers guidance on what to do if an alarm goes off. Each unit features a test/silence button that silences the alarm and allows you to test its functionality. Mounting anchors and screws are included for easy installation on a wall.
