DESCRIPTION Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler VK510 incorpo- rates the capability to suppress specific high-challenge fires. The addition of a larger K-Factor allows ESFR performance at lower end-head pressures than ESFR K14 sprinklers. K25.2 ESFR sprinklers can: • Eliminate the use of in-rack sprinklers when protecting high-piled storage of certain specified materials up to 40 ft. (12.2 m)with ceilings up to 45 ft. (13.7 m)* • Reduce or eliminate the need for a system fire pump. • Provide flexibility when sizing system piping. Viking VK510 ESFR Pendent Sprinklers are primarily intended to protect the following types of storage, which tend to produce severe-challenge fires: palletized and solid pile storage and single, double, multiple row, and portable open rack storage (nom open-top containers or solid shelves). Viking ESFR Pendent VK510 Sprinklers provide protection of most common storage materials, including: • Encapsulated or unencapsulated Class I, II, III, and IV commodities*. • cULus Listed for protection of cartoned unexpanded plastic commodities and FM Approved for protection of cartoned and un- cartoned unexpanded plastic commodities*. • FM Approved for protection of exposed expanded polystyrene and exposed expanded polyurethane commodities*. "Refer the Approval Charts and Design Criteria on pages 124c-e for cULus Listing and FM Approval requirements that must be followed. In addition, some storage arrangements of rolled paper, flammable liquids, aerosols, and rubber tires may be protected by Viking ESFR Pendent Sprinkler VK510. 2.
