1. DESCRIPTION
The Viking Attic Upright VK696 is a specific application concealed space sprinkler
that provides superior fire protection in combustible and non-combustible sloped
attic spaces when used in conjunction with Viking's model V-BB (Back to Back)
and V-SD (Single Directional) specific application sprinklers. Installed in the upright
position, with the deflector parallel to the roof, the Attic Upright used in combination
with the model V-BB increases the allowable span from 60' to 80' (18,3 m to 24,4 m).
Viking Attic Upright sprinklers can be installed with either steel or CPVC piping, and
allow the use of CPVC to feed the protected space below the attic (CPVC allowed
on wet pipe systems only). They are available in brass or with corrosion-resistant
Electroless Nickel PTFE (ENT) coatings where salt water and other corrosive
elements are a consideration. Viking Attic Upright sprinklers are cULus Listed
with specific application guidelines for use as special sprinklers as defined by the
National Fire Protection Association (NFPA), and are listed for specific pitch range
4:12 to 12:12.
