Kidde Carbon Monoxide Detector with 10-Year Battery, 3 LEDs, Replacement Indicator, Test-Reset Button, 2 Pack

The Kidde Carbon Monoxide Detector with 10-Year Battery, model C3010, is a carbon monoxide detector that uses electrochemical sensor technology to detect carbon monoxide. The CO detector is powered by a 10-year lithium battery that never needs replacing, plus protects during a power failure. The Kidde alarm is conveniently designed and portable enough for travel - simply install it on a wall or place it on a tabletop. When carbon monoxide is detected, an 85-decibel alarm will sound & a red LED will flash. A green LED indicates that the alarm is receiving power. And an amber LED indicates when it's time to replace the detector. The test-hush button allows you to test the battery operations as well as temporarily silence the low battery chirp warning. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Certified with a 10-year limited manufacturer's warranty.
