1. DESCRIPTION
Viking Quick Response Extended Coverage Concealed Horizontal Sidewall
Sprinkler VK630 is a thermosensitive spray sprinkler pre-assembled with a
threaded adapter for installation with a domed cover. The glass bulb operating
element and special deflector characteristics meet the challenges of quick
response extended coverage standards.
The special Electroless Nickel PTFE coating has been investigated for installation
in corrosive atmospheres and is listed/approved as corrosion resistant as
indicated in the Approval Chart (NOTE: FM Global approves the ENT coating as
corrosion resistant). The cover plate is not available with ENT finish.
The cover plate provides up to 1/4" (6.35 mm) of horizontal adjustment and is
available with several decorative finishes to meet design requirements. The two-
piece design allows installation and testing of the sprinkler prior to installation of
the cover plate. The "push-on", "thread-off" design of the concealed cover plate
assembly allows easy installation of the cover plate after the system has been
tested and the finish work has been completed. The cover assembly can be
removed and reinstalled, allowing access behind the surface of the wall without
taking the sprinkler system out of service or removing the sprinkler.
