VK514 SPECIFIC APPLICATION ESFR PENDENT SPRINKLER (K28.0)
Viking Specific Application Early Suppression Fast Response (ESFR) Pendent
Sprinkler VK514 incorporates the capability to suppress specific high-challenge
fires. The larger K-Factor allows protection of higher hazard commodities at
greater ceiling heights with lower end-head pressures. K28.0 sprinklers can:
• Provide flexibility of fire protection designs.
• Eliminate the use of in-rack sprinklers when protecting high piled storage of
certain specified materials up to:
UL (Refer to Table 4): 43 ft. (13,1 m) with ceilings up to 48 ft. (14,6 m)*
FM (Refer to Table 5): 50 ft. (15,2 m) with ceilings up to 55 ft. (16,76 m)*
OR
45 ft. (13,5 m) with ceilings up to 50 ft. (15,2 m)*
Viking VK514 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, and portable open rack storage (no
open-top containers or solid shelves). The VK514 is listed to utilize a minimum
aisle width of 6’-0” (UL – 43’ storage or FM – 45’ storage) or 8’-0” (FM – 50’ storage).
Viking ESFR Pendent VK514 Sprinklers provide protection of most common
storage materials, including:
• Encapsulated or unencapsulated Class I, II, III, and IV commodities*.
• UL Listed for protection of cartoned nonexpanded** Group A plastic
commodities*.
• FM Approved for protection of cartoned unexpanded** plastic commodities.*
* Refer the Approval Chart and Commodity Selection and Design Criteria Overview for Listing
and Approval requirements that must be followed.
** The terms “nonexpanded” and “unexpanded” are equivalent.
