Product Description
Model RFC30, RFC43 and RFC49 Concealed Residen-
tial Sprinklers are fast response residential fusible solder
link automatic sprinklers. Residential sprinklers differ from
standard sprinklers primarily in their response time and
water distribution patterns.
Model RFC30, RFC43 and RFC49 sprinklers discharge
water in a hemispherical pattern below the sprinkler de-
flector. Residential distribution patterns are higher and
generally contain a finer droplet size than standard sprin-
kler patterns.
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 RFC30, RFC43 and RFC49 Sprinklers provide the
best form of fire protection by combining an attractive ap-
pearance and ½” (13mm) of cover adjustment for ease of
installation. The small diameter cover plate is easily and
positively attached and blends into the ceiling, concealing
the most dependable fire protection available, an automat-
ic sprinkler system.
The RFC30, RFC43 and RFC49 are UL Listed Residential
Sprinklers to be installed in the residential portions of any
occupancy in accordance with NFPA 13, 13R, & 13D.
The RFC30, RFC43 and RFC49 can reduce the need for
precise cutting of drop nipples. The threaded cover plate
assembly 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 RFC30, RFC43 and RFC49, for residential installa-
tions, use a 165°F (74°C) fusible solder link in a tuning fork
style sprinkler frame with a drop-down deflector. This as-
sembly is recessed 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 ceiling temperature rises, the solder holding
the cover plate releases the cover allowing the deflector
to drop into position and exposing the sprinkler inside to
