Product Description
Model RFC43 and RFC49 Concealed Residential Sprin-
klers are fast response residential fusible solder link au-
tomatic sprinklers. Residential sprinklers differ from stan-
dard sprinklers primarily in their response time and water
distribution patterns.
Model RFC43 and RFC49 sprinklers discharge water
in a hemispherical pattern below the sprinkler deflector.
Residential distribution patterns are higher and generally
contain a finer droplet size than standard sprinkler pat-
terns.
The combination of speed of operation and high dis-
charge pattern required for residential sprinklers has dem-
onstrated, in fire testing, an ability for controlling residen-
tial fires, and thereby providing significant evacuation time
for occupants.
The RFC43 and RFC49 Sprinklers provide the best form
of fire protection by combining an attractive appearance
and ½” (13mm) of cover adjustment for ease of installa-
tion. The small diameter cover plate is easily and posi-

tively attached and blends into the ceiling, concealing the
most dependable fire protection available, an automatic
sprinkler system.
The RFC43 and RFC49 are UL Listed Residential Sprin-
klers to be installed in the residential portions of any occu-
pancy in accordance with NFPA 13, 13R, & 13D.
The RFC43 and RFC49 can reduce the need for precise
cutting of drop nipples. The threaded cover plate assem-
bly can be adjusted without tools to fit accurately against
the ceiling. The fire protection system need not be shut
down to adjust or remove the cover plate assembly.
Application and Installation
The RFC43 and RFC49, for residential installations, use a
165°F (74°C) fusible solder link in a tuning fork style sprin-
kler frame with a drop-down deflector. This assembly is re-
cessed into the ceiling and concealed by a flat cover plate.
The cover plate is attached to the skirt, using 135°F (57°C)
ordinary temperature classification solder. When the ceil-
