Sure Signal Products heat-activated fire alarms sold under the following brand names and models: MasterGuard QR50, Thermalink QR50, and DeTech FST2004H.
The recall involves Sure Signal Products heat activated fire alarms. These alarms are white, round and measure about 18 cm (7 inches) in diameter. The alarms have a round fuse at the center. The fuse is white or chrome and about 4 cm (1.5 inches) in diameter.
The fuses are marked 117°F or 136°F on the label on the back of the fuse, with a date code range from 04001 – 15182. Date codes are listed in “YYDDD” format.
The alarms were manufactured from January 1, 2004 through July 1, 2015. The alarm’s model is printed on a label on the back of the alarm. “SSP”, the temperature rating and the date code can be found on the label on the back of the fuse.
The functionality of the replaceable fusible link sensor (also referred to as the fuse) on the fire alarm can degrade with time, which can cause the alarm to fail to alert a consumer to a fire.
Neither Sure Signals Products nor Health Canada has received any reports of injuries or consumer incidents related to the use of these alarms.
