1. DESCRIPTION
Viking Early Suppression Fast Response (ESFR) Pendent Sprinkler VK500 is a fast
response fusible element type sprinkler designed for early fire suppression. With a 14.0
(202 metric*) nominal K-Factor and special deflector, this sprinkler produces large,
high-momentum water droplets in a hemispheric pattern below the deflector. This
permits penetration of the fire plume and direct wetting of the burning fuel surface while
cooling the atmosphere early in the development of a high-challenge fire.
Viking VK500 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 stor-
age, 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 VK500 Sprinklers provide protection of most common storage
materials, including:
--Encapsulated or unencapsulated Class I, II, III, and IV commodities*.
--Cartoned and uncartoned unexpanded plastics*.
--Cartoned and uncartoned expanded plastics*.
* Refer the Approval Charts and Commodity Selection and Design Criteria Overview for cULus
Listing and FM Approval requirements that must be followed.
In addition, some storage arrangements of rolled paper, aerosols, and rub-
ber tires may be protected by Viking ESFR Pendent Sprinkler VK500.
