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
2.
ceiling temperature. The subsequent operation of the sol-
der link opens the waterway and causes the deflector to
drop into position to distribute the discharging water in a
hemispherical pattern below the sprinkler deflector. Any
adjustment of thread engagement between the cover
plate and cup will assure that the drop-down deflector is
properly located below the ceiling. The residential distri-
bution pattern contains a finer droplet size than a standard
sprinkler, and the pattern produces significantly higher
wall wetting.
After a 25/8inch diameter hole is cut in the ceiling, the
sprinkler is to be installed with the Model FC Wrench.
When installing a sprinkler, the wrench is first positioned
into the sprinkler/cup assembly and around the hexagonal
body of the sprinkler frame. The Wrench must bottom out
against the cup in order to ensure proper, safe installation.
The sprinkler is then tightened into the pipe fitting. When
inserting or removing the wrench from the sprinkler/cup
assembly, care should be taken to prevent damage to
the sprinkler. DO NOT WRENCH ON ANY OTHER PART
OF THE SPRINKLER/CUP ASSEMBLY. MODEL RFC30,
RFC43 AND RFC49 CONCEALED SPRINKLERS MUST
BE INSTALLED ONLY WITH 135°F RATED COVERS.
Note: A leak tight ½” NPT (R1/2) sprinkler joint can be ob-
tained with a torque of 8-18 ft-lbs (10,8 - 24,4 N-m). Do not
tighten sprinklers over maximum recommended torque. It
may cause leakage or impairment of the sprinklers.
Cover assemblies provide up to 1/2” (13mm) of adjust-
ment. Turn the cover clockwise until the flange is in con-
tact with the ceiling. For the push-on/thread-off option, the
cover assembly is pushed onto the cup and final adjust-
ment is made by turning the cover clockwise until the skirt
flange makes full contact with the ceiling. Cover removal
requires turning in the counter-clockwise direction.
In ceilings that have a plenum space above the sprinkler,
the plenum space may have neutral or negative pressur-
ization but must not be positively pressurized. Inspect all
sprinklers after installation to ensure that the gap between
the cover plate and ceiling and the 4 slots in the cup are
all open and free from any air flow impediment.

Maintenance
Model RFC30, RFC43 and RFC49 Concealed Sprinklers
should be inspected quarterly and the sprinkler system
maintained in accordance with NFPA 25. Do not clean
sprinklers with soap and water, ammonia or any other
cleaning fluids. Remove dust by using a soft brush or gen-
tle vacuuming. Remove any sprinkler cover plate assem-
bly which has been painted (other than factory applied) or
damaged in any way. A stock of spare sprinklers should
be maintained to allow quick replacement of damaged or
operated sprinklers. Prior to installation, sprinklers should
be maintained in the original cartons and packaging until
used to minimize the potential for damage to sprinklers
that would cause improper operation or non-operation.
