How long does a First Alert smoke and carbon monoxide alarm last?Smoke alarms should be replaced 10 years from the date of manufacture. Combo smoke/CO alarms should be replaced after 5-7 years (depending on the model). Put the alarm back on the ceiling or wall if it is less than 10 years old. Replace alarm(s) older than 10 years with new units.
Why does my First Alert carbon monoxide alarm keep chirping?If your carbon monoxide alarm keeps chirping, the battery may be low or weak. On First Alert carbon monoxide detectors, check to see if the battery light is yellow or green. If the alarm is chirping and the light is yellow, it means the battery is low.
