Abstract
A fire protection system is provided for a space having a roof including a pitched portion and at least one end portion having a hip, sloping downward from an apex substantially coinciding with an end of the pitched portion toward an eave and extending outward toward the ends of the sides of the pitched portion. The hip may have a lower hip, including jack trusses, and an upper hip, including stepdown trusses. Within the upper hip, at least two rows of sprinklers may be placed, with a first row of sprinklers located substantially at the apex. The maximum allowable spacing between sprinklers in a direction perpendicular to the slope of the hip may be greater than a maximum allowable spacing between rows of sprinklers, i.e., in a direction parallel to the slope of the hip.
