Kidde P4010ACSCO

SaferProducts.gov consumer incident report 20250720-EFF68-2147329432. Severity: Injury, No First Aid or Medical Attention Received. Product: Kidde P4010ACSCO (Kidde 10 year Worry-Free Smoke and Carbon Monoxide Alarm - P4010ACSCO. Hardwired with 10 Year Battery Backup). Incident: I installed 5 Kidde P4010ACSCO Combination Smoke/CO Alarms in my parents' home. Three of the 5 were giving off false alarms on a regular basis, so I returned them to Home Depot for new units. Two of the three replacement units also gave constant false alarms, and my parents had to call the fire department one night and they came and removed the alarm. My father called the Kidde 800 number but there didn't appear to be any resolution, so I wound up replacing the units with similar units from [REDACTED]. I have had no problems with the [REDACTED] units. Looking at the Home Depot reviews on this unit, there are tons of similar complaints, as well as similar complaints to the CPSC on this site. These units need to be recalled - the constant false alarms cause consumers to remove the alarms which is a safety hazard. I used to be legal counsel for Kidde when they were owned by UTC and am shocked that Kidde has not recalled these already given the volume of reviews complaining about this problem. Additionally, the mechanism to turn the 10-year battery off to be able to dispose of these is awkward and requires brute force with a screw driver and I wound up injuring myself switching them off.
