1. DESCRIPTION
The Viking Standard Response ELO Pendent Sprinkler VK536 is a thermosensitive
glass bulb spray sprinkler available in several different finishes and temperature rat-
ings to meet design requirements. The special Polyester and Electroless Nickel PTFE
(ENT) coatings can be used in decorative applications where colors are desired. In
addition, these coatings have been investigated for installation in corrosive atmos-
pheres and are listed/approved as corrosion resistant as indicated in the Approval
Charts.
The extra-large orifice provides greater flows at lower pressures than standard orifice or
large orifice sprinklers. This feature allows reduced pipe sizing for hydraulically calculated
sprinkler systems, which require high densities of water. Viking Standard Response Extra-
Large Orifice Sprinklers may eliminate the need for a fire pump or reduce the size of the
pump if it is required. On existing systems, replacing large orifice sprinklers with extra-large
orifice sprinklers may provide the higher densities required to allow an increase in the hazard
classification of an occupancy.
Viking standard response sprinklers may be ordered and/or used as open sprinklers (glass
bulb and pip cap assembly removed) on deluge systems. Refer to
below.

    1. DESCRIPTION Viking fire sprinklers consist of a threaded frame with a specific waterway or orifice size and a deflector for distributing water in a specified pattern. A closed or sealed sprinkler refers to a complete assembly, including the thermosensitive operating element. An open sprinkler does not use an operating element and is open at all times.
