A fire-sprinkler protection system for a combustible concealed space having a sloped ceiling has a plurality of fire-sprinklers including pendent sprinklers and sidewall sprinklers disposed beneath the sloped ceiling. Each pendent sprinkler provides a spray pattern that is generally circular cylindrical about the sprinkler. Each sidewall sprinkler provides a spray pattern that is generally rectangular in shape. The hydraulic demand for each sprinkler is substantially equivalent to the projection hydraulic demand for the horizontal footprint projection of the sloped ceiling on the floor. A piping system is coupled to each sprinkler by a plurality of branch lines is sized to provide the hydraulic demand for each sprinkler.
