Kidde Smart Plug-In Carbon Monoxide with Indoor Air Quality Monitor

Using electrochemical sensor technology, the Kidde carbon monoxide alarm will detect poisonous CO gas in your home and alert you by sounding an 85-decibel alarm. The Kidde carbon monoxide alarm plugs into a standard, US 120V AC power outlet and has a lithium battery backup in case of power failure, helping to provide continuous protection throughout the 10-year life of the alarm with the benefit of never having to change a battery! The digital display provides real-time status to your home’s air quality, such as unexpected high or low temperatures, high humidity that can lead to mold, or Total Volatile Organic Compounds (TVOC). Provides real-time detection & air quality information & a means to set up alerts for family & friends – even the pet sitter – to alert you to a potentially dangerous situation in your home. The Test-Hush button activates the temporary silence of nuisance alarms & tests the unit. The peak level memory button records the highest CO level reached since the button was last pressed.
