General
Description
The TYCO ILLUSION, 11.2 K-factor,
Extra Large Orifice Concealed Pendent
Sprinklers quick, response, standard
coverage, are decorative, fast response
solder type sprinklers featuring a flat
cover plate designed to conceal the
sprinkler. When limited water pressure
is available and a higher applied water
density is necessary, the ILLUSION
is the best choice for architecturally
sensitive areas such as casinos, hotel
lobbies, office buildings, churches, and
restaurants.
Each unit includes a Cover Plate
Assembly that conceals the sprin-
kler operating components above
the ceiling. The separable two-piece
design of the Cover Plate and Support
Cup Assemblies allows installation of
the sprinklers and pressure testing
of the fire protection system prior to
installation of a suspended ceiling or
application of the finish coating to a
fixed ceiling. They also permit removal
of suspended ceiling panels for access
to building service equipment without
having to first shut down the fire pro-
tection system and remove sprinklers.
Also, the separable two-piece design
of the Sprinkler provides for 3/4 in.
(19,1 mm) of vertical adjustment to
provide a measure of flexibility with
regard to which the length of fixed pipe
drops to the sprinklers must be cut.
The ILLUSION Sprinklers are shipped
with a Disposable Protective Cap. The
Protective Cap is temporarily removed
for installation, and it can be replaced
to help protect the sprinkler while the
ceiling is being installed or finished. The
tip of the Protective Cap can also be
used to mark the center of the ceiling
hole into plaster board, ceiling tiles, etc.
by gently pushing the ceiling product
against the Protective Cap. When the
ceiling installation is complete, the Pro-
tective Cap is re- moved and the Cover
Plate Assembly installed.
As an option, the ILLUSION Pendent
Sprinklers may be fitted with a silicone
Air and Dust Seal (Ref. Figure 4). The
Air and Dust Seal is intended for sensi-
tive areas where it is desirable to stop
air and dust travel through the cover
plate from the area above the ceiling.
