Carbon monoxide (CO) alarms detect the early presence of carbon monoxide emitted from gas sources such as heating and cooking systems, vehicle engines, fuels and blocked chimneys. CO alarms are intended to supplement conventional smoke alarms, not replace them. A CO alarm is not a smoke alarm and, therefore, will not satisfy legal requirements regarding the installation of smoke alarms in the home.
