SaferProducts.gov consumer incident report 20230601-83035-2147347240. Severity: Incident, No Injury. Matched catalog product: Kidde Model P4010DCS-W. Source model text: P4010DCS-W. Incident: Late at night one of our Kidde P4010DCS-W photoelectric smoke alarm with voice and wireless began saying "fire" although no fire/smoke was present. The red light would also alternatively blink along with an amber light, which the raised text on the alarm explains that this indicates a fault. The alarm was placed into hush mode but alarmed again after automatically exiting hush mode. The alarm had to be permanently disabled and discharged with a screwdriver. We contacted Kidde customer service several days ago but have received no reply.

SaferProducts.gov consumer incident report 20260801-EF404-2147313085. Severity: Incident, No Injury. Matched catalog product: Kidde Model P4010DCS-W. Source model text: P4010DCS-W. Incident: Eight Interconnected wireless Kidde smoke alarm/ CO2 detectors installed by prior owner in June 2025. Required by state of RI and only ones approved by the state. They keep going off in 2 of our 3 condo units. Dunns Corners RI Fire Marshall tells me they are no longer sold because they are defective. Kidde however has not issued a recall. We now have to pay again to replace 1 year old alarms that are supposed to have 10 year batteries . Looking to get a recall issued so we and probably thousands of people can use the refund to purchase new, safe , working alarms

Government / agencyIndexed Oct 16, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20240110-34FE2-2147342862. Severity: No Incident, No Injury. Product: Kidde Model P4010DCS-W (Kidde Smoke Alarm / wireless interconnected. Model P4010DCS-W 10 Year Worry-Free Sealed Battery Smoke Detector with Intelligent and Wire-Free Voice Interconnect (2-Pack)). Incident: We bought 6 of these alarms in July 2023 in 5 months have had 5 false alarms. It is a dangerous alarm because everyone has started to assume it is a false alarm when they go off. Our neighbors checked on use the first two times but now they assume it is false. Have been woken up and had to come home from work. They go off when no one is cooking and/or is home. I have tried all the suggestions for placement and dust regularly and am still having issues. We have the correct placement for all alarms. I do like the way when one alarm goes off the others go off which is nice downstairs and our ADU. Since we get so many false alarms it has become unsafe. The first time I called customer service I was on hold for 30 mins and it took 1 hour to get issue resolved. They can only send a replacement and admit that these alarms have issues with being too sensitive. Products like this are why people disable their fire alarms. Nuisance fire alarms like these present big safety issues because frequent false alarms desensitize occupants. If occupants grow accustomed to hearing an alarm without a fire it seriously slows the response time to the alarm. This creates a dangerous situation in the case of a real emergency that can result in significant risk to life. These alarms should be recalled. They have very bad reviews from customers due to this issue.
