The Kidde Carbon Monoxide, Propane, Natural Gas, and Explosive Gas Detector provides reliable protection in a simple plug-in alarm design with a 9-volt battery backup. Advanced electrochemical sensor detects carbon monoxide, methane, sewer gas, propane, and natural gas in your home and alerts you by sounding an 85-decibel alarm. The digital LED display shows either the CO level sensed or the word "GAS" when explosive gas is present. The carbon monoxide and gas alarm plugs into a standard 120V AC outlet for easy set up and the included 9V alkaline battery supplies backup power during an outage. When CO is detected, the digital display shows the levels sensed and updates every 15 seconds. Peak Level Memory records the last time carbon monoxide was detected or when the unit was tested. Smart-Hush button silences the unit for 8 minutes, useful for false alarms from activities such as cooking or shower steam. Included extension cord allows for on table or shelf placement.Alarms should be installed on all levels of the home and near bedrooms. UL Listed and backed by a 10-year limited manufacturer warranty (alarm only; not a battery claim). Meets requirements for UL 2034, UL 217, NFPA 72 (Chapter 11, 2002 ed.), State of California Fire Marshal, NFPA 101 (one & two family dwellings), Federal Housing Authority (FHA), and Housing and Urban Development (HUD). Warranty coverage begins when the alarm is powered; if the activation date is unknown, replacement is recommended.
