1. DESCRIPTION
Viking Standard Response Large Orifice Dry Concealed Pendent Sprinkler VK192
is a thermosensitive spray sprinkler suitable for use in areas subject to freezing. The
sprinkler is designed for dry systems and preaction systems where it is necessary
to prevent water or condensation from entering the drop nipple before sprinkler
operation. The sprinkler may also be installed in spaces subject to freezing and sup-
plied from a wet system in an adjacent heated area. The large orifice dry pendent
sprinkler allows greater flows at lower pressures than standard orifice sprinklers.
The dry concealed sprinkler is pre-assembled with a threaded adapter for installa-
tion with the domed cover that provides up to ½" (12.7 mm) of vertical adjustment.
The push-on, thread-off cover slips on from below the ceiling to allow installation of
the sprinkler prior to ceiling construction.
Viking Standard Response Dry Concealed Pendent Sprinkler VK192 available in
various finishes and temperature ratings to meet design requirements.
