Water discharges immediately from sprinklers when they are <br />opened. Sprinklers open when heat melts fusible link or destroys frangible device. Hose <br />connections are included if indicated. <br />1.05 PERFORMANCE REQUIREMENTS <br />A.Standard Piping System Component Working Pressure: Listed for at least 175 psig (1200 kPa). <br />B.High-Pressure Piping System Component Working Pressure: Listed for 300 psig (2070 kPa). <br />C.Fire-suppression sprinkler system design shall be approved by authorities having jurisdiction. <br />1.Margin of Safety for Available Water Flow and Pressure: 10 percent, including losses <br />through water-service piping, valves, and backflow preventers. <br />2.Sprinkler Occupancy Hazard Classifications: <br />a.Building Service Areas: Ordinary Hazard, Group 1. <br />b.Electrical Equipment Rooms: Ordinary Hazard, Group 1. <br />c.General Storage Areas: Ordinary Hazard, Group 1. <br />d.Mechanical Equipment Rooms: Ordinary Hazard, Group 1. <br />e.Office, Laboratories and Public Areas: Light Hazard. <br />f.Minimum Density for Automatic-Sprinkler Piping Design: <br />1)Ordinary-Hazard, Group 1 Occupancy: 0.15 gpm over 1500-sq. ft. Reduced <br />remote area per NFPA 13 is allowed. <br />2)Light-Hazard Occupancy: 0.10 gpm over 1500-sq. ft. Reduced remote area per <br />NFPA 13 is allowed. <br />g.Maximum Protection Area per Sprinkler: Per UL listing. <br />h.Maximum Protection Area per Sprinkler: <br />1)Office Spaces: 225 sq. ft. <br />2)Storage Areas: 130 sq. ft. <br />3)Library: 225 sq. Ft. <br />4)Mechanical Equipment Rooms: 130 sq. ft. (12.1 sq. m). <br />5)Electrical Equipment Rooms: 130 sq. ft.
