ILLUSION™, 11.2 K-fac-
tor, Standard Coverage, Extra Large
Orifice Concealed Pendent Sprinklers
are decorative, fast response solder
type sprinklers featuring a flat cover
plate designed to conceal the sprin-
kler. When limited water pressure is
available and a higher applied water
density is necessary, the ILLUSION is
the best choice for architecturally sen-
sitive areas such as casinos, hotel lob-
bies, office buildings, churches, and
restaurants.
Each unit includes a Cover Plate As-
sembly that conceals the sprinkler op-
erating components above the ceiling.
The separable two-piece design of the
Cover Plate and Support Cup Assem-
blies allows installation of the sprin-
klers 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 sus-
pended 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 inch

WARNING" that provides cautions
with respect to handling and instal-

it to operate prematurely.

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 ceil-
ing hole into plaster board, ceiling tiles,
etc. by gently pushing the ceiling prod-
uct against the Protective Cap. When
the ceiling installation is complete, the
Protective Cap is removed and the
Cover Plate Assembly installed.
As an option, the ILLUSION Pendent
Sprinklers may be fitted with a silicone
Air and Dust Seal (Ref. Fig. 4). The Air
and Dust Seal is intended for sensitive
areas where it is desirable to stop air
and dust travel through the cover plate
from the area above the ceiling.
