• Push-On cover plate installation

• Low water flow requirements

Product Description

Model RFC Series residential sprinklers are flat cover plate,
concealed pendent sprinklers intended for installation in
accordance with NFPA 13, NFPA 13R, or NFPA 13D. The
sprinklers are cULus Listed as Residential Sprinklers in ac­cordance with UL 1626. In addition, Model RFCLL Series
sprinklers are cULus Certified for Health Effects to NSF/ANSI
standard 61 Annex G (LL) and Australian WaterMark Certified
(WMCS).

Model RFC30 sprinklers have a 165°F (74°C) temperature
rated fusible-link operating element. Model RFC43, RFC49,
RFC58, and RFC76 sprinklers are offered with either a 165°F
(74°C) or 212°F (100°C) temperature rated fusible-link oper­ating element. Sprinklers with a 165°F (74°C) temperature

rating are ordinary temperature classification and are listed
for use with a 135°F (57°C) temperature rated cover plate.
Sprinklers with a 212°F (100°C) temperature rating are inter­mediate temperature classification and are listed for use with
a 165°F (74°C) temperature rated cover plate.

Model RFC Series sprinklers are installed with a Model RFC
cover plate. Model RFC cover plates may be installed by ei­ther pushing or threading the cover plate into the sprinkler
cup. Model RFC30, RFC30LL, RFC43, RFC43LL, RFC49 and
RFC49LL sprinklers allow 1/2” (13 mm) of cover plate adjust­ment. Model RFC58 and RFC76 sprinklers allow 3/4” (19 mm)
of cover plate adjustment. Model RFC cover plates are avail-

Notes:

1. For NFPA 13 installations the flow per sprinkler must be the greater of: (1) the flow listed in Table B above and (2) the flow required to
achieve a minimum design density of 0.1 gpm/sq ft over the design area of the sprinkler.

2. For coverage area dimensions less than those listed above, use the minimum required flow for the next larger max. coverage area listed.
