Fire protection apparatus

摘要

Fire protection apparatus having a conduit formed internally with longitudinally continuous compartments for conveying water or fire-extinguishing gas or foam, and spray nozzles spaced along the conduit and each connected to a different compartment thereof. Combustion detectors are arranged in each of the areas adjacent to the conduit which are covered by the spray from the nozzles and operate a control system selectively supplying fluid to a compartment of the conduit when a fire hazard is detected, so as to supply the particular nozzle or nozzles covering the area where the fire hazard has arisen. An extensive network of piping is avoided and the apparatus can be installed inconspicuously and without the need for robust jointing, sealing and supporting fittings.
