PENDENT <br /> re <br /> q (V2740) <br /> SPRINKLER OPERATION: The operating mechanism is a frangible glass bulb which contains a heat responsive liquid. During <br /> a fire,the ambient temperature rises causing the liquid in the bulb to expand.When the ambient <br /> temperature reaches the rated temperature of the sprinkler,the bulb shatters.As a result,the <br /> waterway is cleared of all sealing parts and water is discharged towards the deflector.The deflector is <br /> designed to distribute the water in a pattern that is most effective in controlling the fire. <br /> COVERAGE: Residential spray coverage up to 20 feet x 20 feet/6.1 m x 6.1 m room sizes per NFPA. <br /> TECHNICAL SPECIFICATIONS: Model:V2740 ACCESSORIES <br /> Style: Pendent and Recessed Pendent Installation Wrench: <br /> Nominal Orifice Size:%e°/12mm Open End:V27 <br /> K-Factor:4.9 Imp./7.1 S.I.A for room sizes up to Recessed:V27-1 <br /> 20'/6.1 m Sprinkler Finishes: <br /> Nominal Thread Size:'h" NPT/15mm 0 Plain brass <br /> Max.Working Pressure: 175psi/12001kPa • Chrome plated <br /> Factory Hydrostatic Test: 100%@ 500psi/ 0 White painted** <br /> 3450kPa • Custom painted** <br /> Min.Operating Pressure:7psi/48kPa For escutcheons,cabinets and other accessories <br /> Temperature Rating:See chart on page 3 refer to separate sheet. <br /> A For K-Factor when pressure is measured in <br /> MATERIAL SPECIFICATIONS <br /> Bar, multiply S.I. units by lark. <br /> Pendent Deflector: Bronze per UNS C51000 *Teflon is a registered trademark of <br /> Bulb: Glass with glycerin solution Dupont Co. <br /> Bulb Nominal Diameter: **UL Listed for corrosion resistance in all <br /> Quick Response:3.Omm configurations. <br /> Load Screw: Bronze per UNS C65100 NOTE:Weather resistant recessed escutcheon <br /> Pip Cap: Bronze per UNS C65100 available upon request. <br /> Seal:Teflon*tape <br /> (;�) Frame: Die cast brass 65-30 <br /> Exaggerated for clarity <br /> JOB/OWNER CONTRACTOR ENGINEER <br /> System No. Submitted By Spec Sect Para <br /> Location Date Approved <br /> Date <br /> www.victaulic.com <br /> VICTAULIC IS A REGISTERED TRADEMARK OF VICTAULIC COMPANY.0 2013 VICTAULIC COMPANY.ALL RIGHTS RESERVED.
