Patent abstract
Methods and systems of fire protection of an attic space having a sloped roof above a ceiling deck so as to define a concealed space defining a protection area. The method includes disposing at least one upright sprinkler having a deflector disposed beneath the roof and coupled to either a wet or a dry pipe system and defining a hydraulic demand of the at least one sprinkler as being equivalent to a hydraulic demand for the protection area so as to eliminate any increase in the hydraulic design area for the sloped roof.
