Fire or Smoke Alarms (702)

Government / agencyIndexed Oct 22, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20250313-EECF5-2147332594. Severity: Incident, No Injury. Matched catalog product: Kidde 20SD10. Incident: Recently installed fire alarms throughout our home. They were the Kidde model# 20SD10. Both units were randomly going off for no cause - after removing from the wall, Kidde stated to use "compressed air" on the unit (??) and to wait 24-hours. After failed efforts, testing was done on a 3rd unit to see if it even worked and while it was inside a smoke filled box, the alarm did not trigger - yet, it would randomly go off the same as the others. So three defective units. Company Support via their toll-free line was mostly unhelpful until the 3rd call in - at which point they agreed to send out replacements. With everything, and the fact that they DID NOT detect the smoke in a controlled test (I am not certified or licensed to test the units) it seems that there are other problems with these units and the company acted as if it was no big deal. This is why I wanted to report the matter to the governing board for full review, as it may help save a life. While no injury (other than my nerves, back, and toes from jumping and stumbling out of bed as if there were a fire) were experienced, I do feel as if the products are unsafe and can stated without a doubt that I believe the company was being dismissive to my reports.

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

SaferProducts.gov consumer incident report 20260904-1A10F-2147310562. Severity: Incident, No Injury. Product: Kidde 20SD10 (Kidde Model 20SD10 battery powered photoelectric smoke alarm with sealed 10-year battery. Residential smoke alarm designed for ceiling or wall installation. The sealed battery is not user replaceable.). Incident: I am a residential rental property owner reporting a recurring pattern of premature failures involving Kidde Model 20SD10 sealed 10-year battery smoke alarms installed in multiple rental dwelling units. Beginning in 2025, I purchased Kidde 20SD10 smoke alarms on multiple separate occasions through Home Depot for installation at different residential rental properties. My Home Depot Pro purchase history documents these purchases over an extended period. The alarms were therefore not all purchased in a single transaction or for installation in a single dwelling unit. These alarms were purchased and installed as part of our compliance with updated HUD smoke alarm requirements that took effect December 29, 2024. These requirements significantly increased the number and placement of compliant smoke alarms required in affected HUD assisted dwelling units, including alarms inside each bedroom, within the required distance of bedroom doors and outside sleeping areas, and on each level of the dwelling. Battery operated alarms are required to have sealed 10-year batteries. We replaced existing smoke alarms and installed additional Kidde 20SD10 alarms as necessary to comply with these requirements. I have now had to replace approximately five Kidde Model 20SD10 alarms prematurely across multiple residential dwelling units. The recurring failure condition has been continuous or intermittent chirping indicating a low battery or malfunction condition. Because the 20SD10 contains a sealed, non-replaceable battery, the battery cannot simply be changed to correct the condition. The entire s
