CA 2717064

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.

L'invention concerne un système de protection contre les incendies pour greniers. Le système comprend un tuyau d'alimentation en liquide servant à fournir un liquide et positionné à une hauteur efficace en dessous du côté intérieur d'un toit ayant un angle d'attaque différent de zéro et parallèlement au côté inférieur du toit. Le système comprend une pluralité de raccords ayant chacun au moins un port de sortie permettant de diriger le flux de liquide, les raccords étant espacés les uns des autres, au plus à une distance maximale efficace, et étant connectés pour recevoir le liquide du tuyau d'alimentation, les ports de sortie étant conçus pour fournir le liquide dans une direction parallèle au côté inférieur du toit. Cependant, de manière plus large, les raccords sont conçus ou disposés de sorte à fournir le liquide dans une direction formant un angle oblique à l'horizontale ou à la verticale, qui peut être ou non exactement identique à l'angle d'attaque du toit. Le système comprend également une pluralité de gicleurs latéraux horizontaux connectés chacun à un port de sortie respectif de l'un ou l'autre des raccords.
