1. DESCRIPTION
Viking Standard Response/Quick Response Extended Coverage Dry Concealed
Pendent sprinklers are thermosensitive spray sprinklers, suitable for use in areas
subject to freezing. The sprinklers are designed for dry systems and preaction sys-
tems where it is necessary to prevent water or condensation from entering the drop
nipple before sprinkler operation. They may also be installed in spaces subject to
freezing and supplied from a wet system in an adjacent heated area.
The dry concealed sprinkler is pre-assembled with a threaded adapter for installa-
tion with the domed cover that provides up to ½" (13 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 Sprinklers are available in vari-
ous finishes and temperature ratings to meet design requirements. The Electroless
Nickel PTFE (ENT) coating has been investigated for installation in corrosive at-
mospheres and is cULus Listed as corrosion resistant as indicated in the Approval
Chart. The ENT finish is only available for the sprinkler assembly, the cover plate is
not plated.
