Two additional detectors repeatedly triggered smoke alarms when no smoke, fire, or hazardous condition was present. A manufacturer-provided warranty replacement unit failed approximately three weeks after receipt. To rule out a wiring or installation issue, I relocated affected detectors to different mounting locations and electrical connections. The failures continued after relocation, indicating the issue was not limited to a specific wiring circuit or installation point. These failures occurred under normal residential conditions and were not associated with cooking, steam, or other known nuisance alarm triggers. Troubleshooting steps recommended by the manufacturer, including resets and battery replacement, did not resolve the issues. Smoke detectors are essential life-safety devices.
