Abstract
An attic fire protection system is provided. The system comprises a fluid supply manifold for supplying a fluid, positioned at an effective height below and parallel to the underside of a roof having a non-zero pitch angle. The system contains a plurality of fittings each having at least one exit port for directing the flow of the fluid, the fittings being spaced within at most a maximum effective distance apart from each other and being connected to receive fluid from the supply manifold, wherein the exit ports are structured to supply the fluid in a direction parallel to the underside of the roof. Most broadly, however, the fittings are structured or arranged to supply the fluid in a direction forming an oblique angle with the horizontal and the vertical, which may or may be exactly the same as the pitch angle of the roof. The system also includes a plurality of horizontal sidewall sprinklers each connected to a respective exit port of one or another of the fittings.
