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 fea-
turing a flat cover plate designed to
conceal the sprinkler. These sprinklers
are optimal for architecturally sensi-
tive areas such as hotel lobbies, office
buildings, churches, and restaurants.
Each sprinkler includes a Cover Plate/
Retainer Assembly and a Sprinkler/
Support Cup Assembly. The separa-
Page 1 of 4
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 application 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 in. (12,7 mm) of ver-
tical adjustment to allow a measure
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
installation 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 pushing
the ceiling product against the Pro-
tective Cap. When ceiling installa-
tion is complete, the Protective Cap is
removed 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.
See 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.
