Sure Signal Products is issuing a recall for several of its heat-activated fire alarms. In the affected models, a defective fusible link sensor on the fire alarm can cause the alarm to fail to alert consumers of a fire. The manufacturer includes about 375,000 units in the recall.

Four models are affected by the defect: the DeTech FST2004H, the MasterGuard QR50, the Responsive TR70-R and the Thermalink QR50. They are white and round with a round fuse in the center. The alarms were manufactured from January 1, 2004 through July 1, 2015. Date codes are listed in a YYDDD format and range from 04001 through 15182. The alarm's model is printed on a label on the back of the alarm.

Consumers could purchase these models from fire alarm dealers nationwide from January 2004 through September 2015 for between $300 and $375.

No incidents or injuries have been reported in connection with these defective products.

Consumers should immediately contact Sure Signal Products for free replacement fuses. A video with instructions on how to replace the fuse is available at
