DESCRIPTION <br /> Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler VK510 <br /> incorporates the capability to suppress specific high-challenge fires.The addition ?. <br /> of a larger K-Factor allows ESFR performance at lower end-head pressures than <br /> ESFR K14 sprinklers. K25.2 ESFR sprinklers can: .: <br /> • Eliminate the use of in-rack sprinklers when protecting high-piled storage of <br /> certain specified materials up to specific heights.` ,. <br /> • Reduce or eliminate the need for a system fire pump. <br /> • Provide flexibility when sizing system piping. • <br /> �• "Y' <br /> Viking VK510 ESFR Pendent Sprinklers are primarily intended to protect the <br /> F, <br /> following types of storage, which tend to produce severe-challenge fires: <br /> palletized and solid pile storage and single, double, multiple row, and portable ;, <br /> open rack storage(no open-top containers or solid shelves). <br /> Viking ESFR Pendent VK510 Sprinklers provide protection of most common <br /> storage materials, including: <br /> • Encapsulated or unencapsulated Class I, II, Ill, and IV commodities". TABLE 1 <br /> • cULus Listed for protection of cartoned unexpanded plastic commodities <br /> and FM Approved for protection of cartoned and uncartoned unexpanded SPRINKLER GENERAL INFORMATION <br /> plastic commodities". <br /> • FM Approved for protection of exposed expanded polystyrene and Sprinkler Identification vK510 <br /> exposed expanded polyurethane commodities*. Number(SIN) <br /> In addition, some storage arrangements of rolled paper, flammable liquids, K-factor,gpm/psi''(Ipm/bar'°) 25.2(363) <br /> aerosols, and rubber tires may be protected by Viking ESFR Pendent <br /> Sprinkler VK510.
