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

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.
