Description
The
Series
RFII, 5.6 K-Factor, Ex-
tended Coverage, Light Hazard
(ECLH) “Royal Flush II” Concealed
Pendent Sprinklers are decorative, 3
mm bulb type sprinklers featuring a flat
cover plate designed to conceal the
sprinkler. It is the best choice for archi-
tecturally sensitive areas such as hotel
lobbies, office buildings, churches,
and restaurants.
They are intended for use in automatic
sprinkler systems designed in accord-
ance with standard installation rules
(e.g., NFPA 13). The fast response
thermal sensitivity rating of the Series
RFII (TY3532) provides for a quick re-
sponse extended coverage (QREC)
rating up to an 18 ft. x 18 ft. coverage
area.
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 sus-
pended ceiling panels for access to
building service equipment without
having to first shut down the fire pro-
tection system and remove sprinklers.
Also, the separable two-piece design
of the the Sprinkler provides for 1/2
inch (12,7 mm) of vertical adjustment,
to reduce the accuracy to which the
length of fixed pipe drops to the sprin-
klers must be cut.
The Series RFII
Sprinklers are
shipped with a Disposable Protective
Cap. The Protective Cap is temporarily
removed for installation, and then it
can be replaced to help protect the
sprinkler while the ceiling is being in-
stalled or finished. The tip of the Pro-
tective Cap can also be used to mark
the center of the ceiling hole into plas-
ter board, ceiling tiles, etc. by gently
pushing the ceiling product against the
Protective Cap. When the ceiling in-
stallation is complete the Protective
Cap is removed and the Cover Plate
Assembly installed.
