DESCRIPTION <br /> Viking Mirage® Standard and Quick Response Concealed Pendent Sprinkler VK462 <br /> and HP Sprinkler VK463 are thermosensitive glass-bulb spray sprinklers designed for <br /> installation on concealed pipe systems where the appearance of a smooth ceiling is <br /> desired. <br /> The sprinkler is pre-assembled with a threaded adapter for installation with a low-pro- <br /> file cover assembly that provides up to%' (12.7 mm)of vertical adjustment.The two- <br /> piece design allows installation and testing of the sprinkler prior to installation of the <br /> cover plate.The"push-on", "thread-off'design of the concealed cover plate assembly . <br /> allows easy installation of the cover plate after the system has been tested and the <br /> ceiling finish has been applied. The cover assembly can be removed and reinstalled, <br /> allowing temporary removal of ceiling panels without taking the sprinkler system out <br /> of service or removing the sprinkler. <br /> 2.

TECHNICAL DATA <br /> Specifications: <br /> Available since 2006. <br /> Minimum Operating Pressure: 7 psi (0.5 bar)* <br /> Maximum Working Pressure: Sprinkler VK463 is rated for use with water working pressures ranging from the minimum <br /> 7 psi (0.5 bar) up to 250 psi (17.2 bar) for high-pressure systems. High-pressure (HP)sprinklers can be identified by <br /> locating "250"stamped on the deflector.Sprinkler VK462 is rated to a maximum 175 psi(12 bar)wwp. <br /> Factory tested hydrostatically to 500 psi (34.5 bar) <br /> Thread size: 1/2" (15 mm) NPT <br /> Nominal K-Factor: 5.6 U.S. (80.6 metrict) <br /> Glass-bulb fluid temperature rated to-65°F(-55*C) <br /> Patents Pending <br /> *cULus Listing, FM Approval, and NFPA 13 installs require a minimum of 7 psi (0.5 bar). The minimum operating pressure for LPCB and CE <br /> Approvals ONLY is 5 psi(0.35 bar). <br /> tMetric K-factor measurement shown is when pressure is measured in Bar.When pressure is measured in kPa,divide the metric K-factor shown by 10.0. <br /> Material Standards: <br /> Sprinkler Body: Brass UNS-C84400 <br /> Deflector: Copper UNS-Cl9500 for Sprinkler VK462 Viking Technical Data may be found on <br /> Phosphor Bronze UNS-051000 for Sprinkler VK463 The Viking Corporation's Web site at <br /> Deflector Pins: Stainless Steel Alloy hftp://Www.vikinggroupinc.com. <br /> Bulb: Glass, nominal 3 mm diameter P clude aimore r. <br /> The Web site may include a more recent <br /> Pip Cap and Insert Assembly: Copper UNS-Cl1000 and Stainless Steel edition of this Technical Data Page. <br /> UNS-S30400 <br /> Button: Brass UNS-C36000 <br /> Screws: 18-8 Stainless Steel <br /> Belleville Spring Sealing Assembly: Nickel Alloy, coated on both sides with Teflon Tape <br /> Yoke: Phosphor Bronze UNS-051000 <br /> Cover Adapter: Cold Rolled Steel UNS-G10080, Finish: Clear Chromate over Zinc Plating <br /> Form No. F_103005 Replaces page 54a-f, dated April 8, 2011. <br /> (Revised VdS Approval.) <br />
