1. DESCRIPTION
Viking Mirage
Quick Response Concealed Pendent Sprinkler VK464 is a thermosensitive
®
glass-bulb spray sprinkler 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" (13 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 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.

4. INSTALLATION

5. OPERATION
During fire conditions, when the temperature around the sprinkler approaches its operating temperature, the cover plate detaches.
Continued heating of the exposed sprinkler causes the heat-sensitive liquid in the glass bulb to expand and the bulb to shatter,
releasing the yoke, pip-cap and sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector,
forming a uniform spray pattern to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
