3. PRODUCT DESCRIPTION
Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler SIN VK510 is an extension of prior ESFR technology.
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.
•
Provide a maximum ceiling-to-element distance of 18 inches (457 mm). (Refer to Design Criteria on page 124 d.)
Viking SIN VK510 ESFR Pendent Sprinklers may be used in the protection of ordinary types of storage. However, they 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 (no open-top containers or solid shelves).
Viking ESFR Pendent SIN 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
uncartoned unexpanded plastic commodities*.
•
FM Approved for protection of exposed expanded polystyrene and exposed expanded polyurethane commodities*.
In addition, some storage arrangements of rolled paper, flammable liquids, aerosols, and rubber tires may be protected by
Viking ESFR Pendent Sprinkler SIN VK510.
