Series RFII — 5.6 K-factor
"Royal Flush II" Concealed Pendent Sprinklers
Quick & Standard Response, Standard Coverage
General
Description
The TYCO Series RFII 5.6 K-factor,
"Royal Flush II" Concealed Pendent
Sprinklers Quick Response (3-mm
bulb) and Standard Response (5-mm
bulb), are decorative sprinklers featur-
ing a flat cover plate designed to con-
ceal the sprinkler. These sprinklers are
optimal for architecturally sensitive ar-
eas such as hotel lobbies, office build-
ings, churches, and restaurants.
Each sprinkler includes a Cover Plate/
Retainer Assembly and a Sprinkler/
Support Cup Assembly. The separa-
ble, two-piece assembly design pro-
vides the following benefits:
• Allows installation of the sprinklers
and pressure testing of the fire pro-
tection system prior to installation
of a suspended ceiling or applica-
tion of the finish coating to a fixed
ceiling.
• Permits the removal of suspended
ceiling panels for access to building
service equipment without having
to first shut down the fire protection
system and remove sprinklers.
• Provides for 1/2 inch (12,7 mm) of
vertical adjustment to allow a mea-
sure of flexibility in determining the
length of fixed piping to cut for the
sprinkler drops.
The Series RFII Sprinklers are shipped
with a Disposable Protective Cap. The
Protective Cap is temporarily removed
during installation and replaced to help
protect the sprinkler during ceiling in-

Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-

a sprinkler system or its components
and cause the sprinkler to fail to

to operate prematurely.

stallation or finish. The tip of the Pro-
tective Cap can be used to mark the
center of the ceiling hole into plaster
board or ceiling tiles by gently push-
ing the ceiling product against the Pro-
tective Cap. When ceiling installation
is complete, the Protective Cap is re-
moved and the Cover Plate/Retainer
Assembly is installed.
As an option, the Series RFII Standard
Response (5-mm bulb) "Royal Flush II"
Concealed Pendent Sprinklers can be
fitted with a silicone Air and Dust Seal.
(Refer to Figure 5.) The Air and Dust
Seal is intended for sensitive areas
where it is desirable to prevent air and
dust from the area above the ceiling to
pass through the cover plate.
