First Alert Carbon Monoxide Detectors
First Alert carbon monoxide alarms: a 120V CO detector with 9V battery backup, a 120V photoelectric smoke and CO alarm, and a hardwired ionization smoke and CO alarm with 10-year lithium battery backup, plus a hardwired photoelectric smoke alarm. Install CO alarms near sleeping areas and replace them by the date on the unit, usually every 7 to 10 years.
Shop all carbon monoxide detectors, or see First Alert smoke detectors. Use a licensed electrician for 120V units.
