Series RFII — 5.6 K-factor
Royal Flush II Concealed Pendent Sprinklers
Quick Response, Extended Coverage
General
Description
The TYCO Series RFII, 5.6 K-fac-
tor, Royal Flush Concealed Pendent
Sprinklers, (TY3532), Quick Response,
Extended Coverage, Light Hazard
(ECLH) are decorative, 3 mm bulb-
type sprinklers featuring a flat cover
plate designed to conceal the sprinkler.
These sprinklers are optimal for archi-
tecturally sensitive areas such as hotel
lobbies, office buildings, churches, and
restaurants.
The Series RFII sprinklers are intended
for use in automatic sprinkler systems
designed in accordance with standard
installation rules (e.g., NFPA 13). The
fast-response thermal sensitivity rating
of the Series RFII (TY3532) provides for
a quick response, extended coverage
(QREC) rating up to a 20 ft x 20 ft cov-
erage area.
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 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.
IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
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.

• 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 sprin-
kler 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.
