SaferProducts.gov consumer incident report 20250225-EA706-2147332926. Severity: No Incident, No Injury. Matched catalog product: Kidde P4010ACS. Source model text: P4010ACSC-WF. Incident: I own the Kidde smart smoke alarm, model P4010ACSC-WF, that worked mostly fine for 3 years with occasional connectivity issues. Recently, the smoke alarm connectivity issues had lasted for almost a month, much longer than normal. I attempted to test the smoke alarm only to discover the testing failed, the smoke alarm would not sound at all. I disconnected and reconnected power to the device, which did not resolve the issue - testing still failed to sound the alarm. After being disconnected from power for a full day, the device finally started testing successfully again. I'm less concerned about the connectivity issues and most concerned that the device was malfunctioning and would not sound the alarm. I reported the defective device to Kidde, but Kidde refused to acknowledge this behavior as a problem and even refused to replace the device. It is concerning to think how long this device might have been in a malfunctioning state, not offering any protection to my home and family. The device offered no beep, no chirp to indicating it was malfunctioning.
