1. DESCRIPTION
Viking Mirage
Standard and Quick Response Concealed Pendent Sprinkler VK462
®
and HP Sprinkler VK463 are thermosensitive glass-bulb spray sprinklers designed for
installation on concealed pipe systems where the appearance of a smooth ceiling is
desired.
The sprinkler is pre-assembled with a threaded adapter for installation with a low-
profile cover assembly that provides up to ½" (12.7 mm) of vertical adjustment. The
two-piece design allows installation and testing of the sprinkler prior to installation of
the cover plate. The "The "push-on" and "thread-on" designs of the concealed cover
plate assemblies allow easy installation of the cover plate after the system has been
tested and the ceiling finish has been applied. The cover assembly can be removed
and reinstalled, allowing temporary removal of ceiling panels without taking the sprinkler
system out of service or removing the sprinkler. The Electroless Nickel PTFE (ENT)
coating has been investigated for installation in corrosive environments and is listed and
approved as indicated in the Approval Charts. The ENT finish is only available for the
sprinkler assembly, the cover plate is not plated.
