First Alert

First Alert Battery Powered Carbon Monoxide Digital Alarm

  • The First Alert CO4106A is a battery powered carbon monoxide alarm with built in LCD screen to display status when a button is pressed or carbon monoxide is detected. The alarm runs on AA batteries so it can be placed wherever it's needed and has a loud built in 85dB siren that sounds when the CO is detected. The CO4106A is for use indoors and is commonly installed in homes, cottages, RV's, or motor homes for bedrooms, basements, living rooms or near fireplaces or appliances that may potentially emit carbon monoxide. The CO4106A uses an electrochemical sensor for increased accuracy and features an easily accessed battery door, mute/silence button and end-of-life timer to alert when replacement is needed.
