1. DESCRIPTION
Viking Mirage
Quick Response ELO Concealed Pendent Sprinkler SIN VK469 is
®
a thermosensitive solder link 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 "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.
The extra-large orifice provides greater flows at lower pressures than standard orifice
or large orifice sprinklers. This feature allows higher densities of water to be applied
when limited water pressure is available.
Viking Quick Response Extra-Large Orifice Sprinklers may eliminate the need for a fire
pump or reduce the size of the pump if it is required. On existing systems, replacing
large orifice sprinklers with extra-large orifice sprinklers may provide the higher
densities required to allow an increase in the hazard classification of an occupancy.

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 fusible element assembly to disengage, releasing seat 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.
