VALVE ACTUATORS No electro-explosive devices may be used to actuate the valve assembly. Electric actuators shall be a continuous duty type for 24 VDC operations. Actuation devices shall be UL Listed and FM Approved for use with the INERGEN iFLOW fire suppression system. DISCHARGE HOSE / HORIZONTAL CHECK VALVE When manifolding, all container assemblies shall include the matrix system, flexible discharge hose, and horizontal check valve for connection to the manifold inlet. All hose / check valves shall be UL Listed and/or FM Approved for use with the iFLOW valve as manufactured by Johnson Controls. DISCHARGE NOZZLES Standard Discharge Nozzle Discharge nozzles shall be of two-piece construction and sized to provide flow rates in accordance with system design flow calculations. A nozzle inlet orifice plate shall be included. The orifice size shall be determined by a computerized UL listed flow calculation program. Orifice(s) shall be machined in the nozzle body to provide a horizontal discharge pattern based upon the approved coverage arrangements. Nozzles shall be permanently marked with the manufacturer's part number. The nozzles shall be threaded directly to the discharge piping without the use of special adapters. Nozzles shall be UL listed as manufactured by Johnson Controls. Acoustic Damping Discharge Nozzle Acoustic damping discharge nozzles shall be used in installations requiring reduced acoustic footprint, such as data centers. The reduced acoustic footprint limits sensitive electronics from being exposed to high sound levels. For acoustic sensitive installations, an acoustic impact evaluation should be performed specific to the hazard area being protected. The report shall include the sound power generated by the suppression system, room parameters and estimated sound pressure level impact on sensitive electronic equipment such as Hard Disc Drives. The sound pressure level impact on Hard Disc Drives shall be below 110dbZ across the 1/3 octave sound bands from 500Hz to 10K Hz. Discharge nozzles shall be constructed to provide flow rates in accordance with system design flow calculations. The nozzles shall be threaded to the discharge piping via an orifice pipe assembly that includes the nozzle inlet orifice plate. The nozzle orifice plate drill size shall be determined by a computerized UL listed flow calculation program.
