Sure Signal Products Recalls Heat-Activated Fire Alarms Due to Failure to Alert Consumers of a Fire

Agency Publication Date: October 29, 2015

Sign in to monitor this recall

Summary

About 375,000 heat-activated fire alarms sold under the brand names DeTech, MasterGuard, Responsive, and Thermalink are being recalled. A defective fusible link sensor (fuse) at the center of the alarm can fail, preventing the device from alerting occupants in the event of a fire. These white, round alarms are approximately 7 inches in diameter and were sold by fire alarm dealers nationwide between January 2004 and September 2015.

Risk

The defective fuse prevents the alarm from triggering when high temperatures are detected, which could lead to delayed notification of a fire and increase the risk of serious injury or death. No injuries have been reported to date.

What You Should Do

  1. Identify your fire alarm by checking for the following brand names and models: DeTech FST2004H, MasterGuard QR50, Responsive TR70-R, or Thermalink QR50. These are white, round alarms with a 1.5-inch white or chrome center fuse.
  2. Verify if your unit is affected by checking the model name on the back of the alarm and looking for a date code in YYDDD format on the back of the center fuse. Recalled units have date codes ranging from 04001 through 15182 (manufactured between January 1, 2004, and July 1, 2015).
  3. If your alarm is a MasterGuard, ThermaLINK, or Responsive brand, contact Global Health and Safety at 972-393-5500 or email info@masterguard.com for free replacement fuses.
  4. If your alarm is a DeTech brand, contact Reliance Products at 262-236-0123 or email contactus@detech.com for free replacement fuses.
  5. Follow the installation instructions provided with the replacement fuses or view the instructional video previously hosted at http://SureSignalProducts.com to ensure the new fuse is correctly installed.
  6. For additional questions or to report a safety concern, contact the CPSC Hotline at 800-638-2772.
