Commercial Fire Alarm and Accidental Sprinkler Activation at Albertsons, Fallbrook

Summary: A commercial fire alarm was reported at the Albertsons supermarket located at 1133 South Mission Road in Fallbrook, San Diego County, California. Initial dispatch involved multiple fire engines, including Engine 1113 and Engine 3381. The alarm was first believed to be a false activation caused by a contractor pulling a pull station. However, upon further investigation, crews discovered an active sprinkler activation in the rear freezer unit accompanied by a smell of smoke, though no active fire was found. The system was reset but remained in trouble due to a malfunction. The incident was ultimately confirmed as a system malfunction, and all units returned to service.
