SaferProducts.gov consumer incident report 20260818-56BFF-2147312240. Severity: Incident, No Injury. Matched catalog product: First Alert SC5. Incident: I have 9 First Alert Smoke detectors that have been installed new for about 3 months. Two of the devices have caused false alarms in the past two days. One false alarm on August 16 2026 which would not clear and caused a fire emergency response by Arlington County Fire department. The second false alarm was today from a separate unit that I was able to clear. This is no acceptable function from a family safety product.

SaferProducts.gov consumer incident report 20260210-223E1-2147323696. Severity: Incident, No Injury. Product: First Alert SC5 (First Alert SC5 Smoke detecotor). Incident: I am submitting this complaint to report repeated failures of First Alert SC5 smoke detectors, which are marketed and sold as critical life-safety devices.

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. As a Deputy Fire Chief, I know that repeated false alarms and early unit failures undermine confidence in the product and may lead occupants to ignore alarms or disable the devices, increasing the risk of injury or death during an actual fire.
