First Alert Battery Powered Carbon Monoxide Digital Alarm

  • The First Alert 1039724 is a battery powered carbon monoxide alarm with backlit digital LED 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 CO is detected. The 1039724 is for use indoors and is commonly installed in homes, cottages, RV's, or motor homes and is great for bedrooms, basements, living rooms or near fireplaces or appliances that may potentially emit carbon monoxide. The 1039724 uses an advanced electrochemical sensor for increased accuracy and features an easily accessed battery door and mute/silence button.
