Opening of sprinklers releases compressed air and permits water pressure to open dry-pipe valve. Water then flows into piping and discharges from opened sprinklers.Combined Dry-Pipe and Preaction Sprinkler System: Automatic sprinklers are attached to piping containing compressed air. Fire-detection system, located in same area as sprinklers, actuates tripping devices that open dry-pipe valve without loss of air pressure and actuates fire alarm. Water discharges from opened sprinklers.Single-Interlock Preaction Sprinkler System: Automatic sprinklers are attached to piping containing low-pressure air. Actuation of fire-detection system, located in same area as sprinklers, opens deluge valve, permitting water to flow into sprinkler piping and to discharge from opened sprinklers.Double-Interlock Preaction Sprinkler System: Automatic sprinklers are attached to piping containing low-pressure air. Actuation of a fire-detection system, located in same area as sprinklers, and simultaneous activation of low pressure switch due to loss of air pressure activates special hazard panel, energizing a normally closed solenoid which opens deluge valve, permitting water to flow into sprinkler piping. Water will then discharge from opened sprinklers.PERFORMANCE REQUIREMENTSElectrical Components, Devices, and Accessories: Listed and labeled as defined in NFPA70, by a qualified testing agency, and marked for intended location and application.Sprinkler system equipment, specialties, accessories, installation, and testing shall comply with the following:NFPA13.NFPA13R.Standard-Pressure Piping System Component: Listed for 175-psig (1200-kPa) minimum working pressure.Retain "Delegated Design" Paragraph below if Contractor is required to assume responsibility for design.Delegated Design: Engage a qualified professional engineer, as defined in Section014000 "Quality Requirements," to design dry-pipe sprinkler systems.Retain data in first subparagraph below if known and if Owner wants to furnish test data to Contractor.Available fire-hydrant flow test records indicate the following conditions:Date: .Time: [a.m.] [p.m.]Performed by: of .Location of Residual Fire HydrantR: .Location of Flow Fire HydrantF: .Static Pressure at Residual Fire HydrantR: .Measured Flow at Flow Fire HydrantF: .Residual Pressure at Residual Fire HydrantR: .Sprinkler system design shall be approved by authorities having jurisdiction.The margin-of-safety requirement may not be required by authorities having jurisdiction.
