Series RFII — 5.6 K-factor
"Royal Flush II" Pendent Concealed Sprinklers
Quick & Standard Response, Standard Coverage
General
Description
The Tyco
Series RFII Quick Response
®
(3 mm bulb) & Standard Response (5
mm bulb), 5.6 K-Factor, "Royal Flush
II" Concealed Pendent Sprinklers are
decorative sprinklers featuring a flat
cover plate designed to conceal the
sprinkler. It is the best choice for archi-
tecturally sensitive areas such as ho-
tel lobbies, 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 suspend-
ed ceiling panels for access to building
service equipment without having to
first shut down the fire protection sys-
tem and remove sprinklers.
Also, the separable two-piece design
of the Sprinkler provides for 1/2 inch
(12,7 mm) of vertical adjustment, to
provide a measure of flexibility with re-
gard to which the length of fixed pipe
drops to the sprinklers must be cut.
The Series RFII Sprinklers are shipped
with a Disposable Protective Cap. The
IMPORTANT
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 in-
stallation can permanently damage
a sprinkler system or its components
and cause the sprinkler to fail to
operate in a fire situation or cause it
to operate prematurely.

Protective Cap is temporarily removed
for installation, and then it can be re-
placed 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 Protec-
tive Cap. When the ceiling installation
is complete the Protective Cap is re-
moved and the Cover Plate Assembly
installed.
As an option, the Series RFII Standard
Response (5 mm bulb) "Royal Flush II"
Concealed Pendent Sprinklers may be
fitted with a silicone Air and Dust Seal
(Ref. Fig. 5). 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.
NOTIce

Sprinklers described herein must be

cable standards of the National Fire
