Nursing Home/Senior Living, Residential Sprinkler system puts out fire at senior apartment complex (Payson, AZ) November 7, 2014 viking210 Crews responded to a small fire Wednesday morning at the Canal Senior Apartments that activated the building’s fire sprinkler system. No one was injured. It appears a candle burning in a resident’s living room lit some nearby decorative dried reeds on fire, setting the sprinklers off, which quashed the flames before it could spread.
