General
Description
The TYCO Model RFII, 5.6 K-factor,
Horizontal Sidewall (HSW), Flat Plate
Concealed Sprinkler, Quick Response
Standard Coverage is a decorative, link
type sprinkler featuring a unique flat
cover designed to conceal the sprin-
kler within a wall. The sprinkler is the
best choice for architecturally sensi-
tive areas such as dormitories, hotel
rooms, reception areas, office build-
ings, banquet facilities, conference
rooms, and hospitals.
The flat profile of the cover plate design
easily conforms to the surrounding sur-
faces leaving a very clean look. The
plate, while being aesthetically appeal-
ing, also helps to prevent objects such
as garment bags and clothes hangers
from being hung from the sprinkler that
may otherwise cause an inadvertent
operation.
The Model RFII HSW Concealed Sprin-
kler is designed for installation along a
wall or the side of a beam, and beneath
a smooth level ceiling. Horizontal side-
wall sprinklers are commonly used in
lieu of pendent or upright sprinklers
because of aesthetics or building con-
struction considerations where piping
across the ceiling is not desirable.
The Model RFII HSW Sprinklers are
intended to be used in automatic
sprinkler systems designed in accor-

regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

dance with standard installation rules,
for example, NFPA 13, for ordinary and
light hazard occupancies.
Cover Plate Assemblies are available in
a variety of colors and ordered sepa-
rately. When properly installed, cover
plates conceal operational parts of the
sprinklers. Together, the sprinkler and
cover plate form a complete assembly.
The separable two-piece design of the
sprinkler provides for 1/4 in. (6,4 mm)
horizontal adjustment of the push-on
and pull-off cover plate. With sprinklers
installed but before cover plates are
attached, pressure testing of the fire
protection system may be performed
prior to completing wall assemblies
such as installation of gypsum board
over stud framing, and surface finish-
ing such as painting or wallpapering.
The Model RFII HSW Concealed
Sprinkler is factory assembled and
shipped with a Protective Cap. The
Protective Cap must remain in place
to protect the sprinkler during instal-
lation, see Figure 4, and wall instal-
lation and finishing. The cap may be
temporarily removed to verify proper
orientation of the sprinkler deflector
as necessary, but must be reinstalled
and remain attached until the wall is fin-
ished. The cap features a convenient
center marking tip. With the sprinkler
installed and cap attached, see Figure
3, align the wall covering material with
the framing studs and gently press
against the cap tip. The indentation
left by this action marks the center for
cutting a 2-5/8 in. (66,7 mm) diameter
clearance hole for the sprinkler. After
the wall installation and finishing are
complete, the Protective Cap must be
removed and the Cover Plate Assem-
bly installed. Removal of the Protective
Cap is crucial to ensure proper perfor-
mance of the sprinkler.
