Product Description
F1FR56-300 Upright, Pendent, Recessed Pendent,
and Concealed Pendent
Reliable Models F1FR56–300 QR Upright, Pendent and
Recessed Pendent Sprinklers are high pressure rated au-
tomatic sprinklers which can handle a maximum service
pressure of 300 psi (20,7 bar).
The Reliable Model F1FR56-300/CCP Quick Response
Concealed Sprinkler is an attractive, low profile concealed
sprinkler assembly. This sprinkler assembly utilizes a
Model F1FR56-300 pendent sprinkler in a Model CCP
cup and cover plate assembly. The cup is securely fac-
tory threaded on the sprinkler inlet end. The assembly is
shipped with a protective cap. The sprinkler and cup are
easily installed into the drop nipple using the Model GFR2
Sprinkler Wrench. The cover plate assembly is attached to
the sprinkler cup using a cover plate assembly with flex-
ible tabs for threaded engagement. Simply push on the
cover plate, then turn to adjust or remove the cover plate
assembly.
The cover plate is attached to the skirt using 135°F
(57°C) or 165°F (74°C) ordinary temperature classifica-
tion solder. When the ceiling temperature rises, the solder
holding the cover plate melts, allowing the release of this
part and thus exposing the Model F1FR56-300 sprinkler
inside to the rising ambient temperature.
These automatic sprinklers are quick response sprin-
klers which utilize a 3.0mm frangible glass bulb. They
have demonstrated response times in laboratory tests
which are five to ten times faster than standard response
sprinklers. This quick response enables Model F1FR56-
300 sprinklers to apply water to a fire much faster than
standard response sprinklers of the same temperature rat-
ing.
The glass bulb contains an accurately controlled amount
of special fluid hermetically sealed inside. The other sprin-
kler parts are made of brass, copper or beryllium nickel.
At normal temperatures, the glass bulb contains fluid in
both the liquid and vapor phases. The vapor phase can
be seen as a small bubble. As heat is applied, the liquid
expands, forcing the bubble smaller and smaller as the
liquid pressure increases. Continued heating forces the
liquid to push out against the bulb, causing the glass to
shatter, opening the waterway and allowing the deflector
to distribute the discharging water.
The temperature rating of the sprinkler is identified by the
color of the glass bulb.

F1FR56-300 Horizontal Sidewall, F1FR56-300 Horizon-
tal Sidewall Recessed & F1FR56-300 Horizontal Side-
wall Concealed
Models F1FR56-300 Horizontal Sidewall, F1FR56-300
Horizontal Sidewall Recessed and SWC56 Concealed are
quick response type sprinklers. Model F1FR56-300 Hori-
zontal Sidewall Recessed and SWC56 assemblies utilize the
push-on / thread-off escutcheon and cover-plate, respec-
tively. These assemblies are shipped with a protective cap.
Remove cap to enable mounting the F1FR56-300 Horizon-
tal Sidewall sprinkler/cup assembly in place and then push
or thread the escutcheon or cover-plate into the installed
sprinkler/cup assembly. When the F1FR56-300 Horizontal
Sidewall is ordered with the F2 escutcheon the sprinkler and
escutcheon assembly are shipped separately. The sprinkler
and collar must be assembled together before the sprinkler
can be installed in a fitting.
The SWC56 sprinkler’s cover is attached to its skirt us-
ing 135°F (57°C) ordinary temperature classification solder.
When the ambient temperature rises, the solder holding the
cover-plate melts, allowing the release of this part and thus
exposing the sprinkler inside to the rising ambient tempera-
ture.
The Model F1FR56-300 Horizontal Sidewall utilizes a
3.0mm frangible glass bulb. This allows quick response
which enables the sprinkler to apply water to a fire sooner
than standard sprinklers of the same temperature rating.
Application and Installation
The most common applications for Model F1FR56-300 Se-
ries Quick Response Sprinklers will be in fire protection sys-
tems for high rise buildings where a quick response rating is
required and the pressure entering the sprinkler system is in
excess of 175 psi (12 bar). The use of these sprinklers will
provide opportunity to reduce or eliminate the need for pres-
sure reducing valves.
The Model F1FR56-300/CCP Concealed Sprinkler Assem-
bly uses a ½” (15mm) orifice, ½” NPT (R½), 135°F (57°C),
155°F (68°C), 175°F (79°C), or 200°F (93°C) rated Model
F1FR56-300 Pendent Sprinkler with a threaded Model CCP
cup, which is factory attached to the sprinkler. The assem-
bly is completed by the installation of an attractive, low pro-
file, 135°F (57°C) or 165°F (74°C) rated Model CCP push
on cover plate assembly. The cover plate and sprinkler cup
assemblies are joined using a cover plate with flexible tabs
for threaded engagement. A choice of two cover plate as-
semblies provide either ½” (13mm) or 5/16” (8mm) of cover
adjustment.
Do not install these sprinklers in ceiling which have positive
pressure in the space above.
After a 25/8” (67mm) diameter hole is cut in the ceiling, the
sprinkler is easily installed with the Model GFR2 Wrench.
A PTFE thread sealant should be applied to the sprinkler
threads only. The Model GFR2 Wrench is then used to en-
gage the sprinkler wrenching surfaces and to install the
sprinkler in the fitting. When inserting or removing the wrench
from the sprinkler/cup assembly, DO NOT WRENCH ON
ANY OTHER PART OF THE SPRINKLER. The cover plate is
then pushed onto the cup. Final adjustment is made by hand
turning the cover plate until the skirt flange makes full contact
with the ceiling. Cover plate removal requires turning in the
counter clockwise direction.
After installation, inspect all sprinklers to ensure that there is
a gap between the cover plate and ceiling and that the four
cup slots are open and free from any air flow impediment to
the space above.
Concealed cover plate/cup assemblies are listed only for
use on specific sprinklers. The use of any other concealed
cover plate/cup assembly with the Model F1FR56-300 Pen-
dent Sprinkler or the use of the Model CCP concealed cover
plate assembly on any sprinkler with which it is not specifi-
cally listed may prevent good fire protection and will void all
guarantees, warranties, listings and approvals.
Quick response sprinklers are intended for installation as
specified in NFPA 13. Quick response sprinklers and stan-
dard response sprinklers should not be intermixed.
The Model F1FR Series Recessed and Concealed Quick
Response Sprinklers are to be installed as shown.
When installing Model F1FR56-300 Upright and Pendent
Sprinklers, use the Model W2 Sprinkler Wrench. Use the
Model GFR2 Wrench for installing F1FR-300 Recessed and
Concealed Pendent Sprinklers. Any other type of wrench
may damage these sprinklers.
Glass bulb sprinklers have orange covers to protect the
bulb during the installation process. REMOVE THIS PRO-
TECTION ONLY AFTER THE SYSTEM HAS BEEN HYDRO-
STATICALLY TESTED AND, WHEN APPLICABLE, THE ES-
CUTCHEONS HAVE BEEN INSTALLED. RASCO wrenches
are designed to install sprinklers when covers are in place.
The Model F1FR56-300 Horizontal Sidewall sprinkler is in-
tended for installation in light & ordinary hazard occupancies
in accordance with NFPA 13. This sprinkler is especially well-
suited for use in student dormitories, hotels, hospitals and
care facilities, and can be used where the pressure entering
the sprinkler system calls for 300 psi (20,7 bar) applications.
Models F1FR56-300 Horizontal Sidewall recessed and
SWC56 concealed sprinklers utilize a threaded cup which
is factory attached to the sprinkler. The assembly is com-
pleted by the installation of the attractive push-on/thread-off
escutcheon and135°F (57°C) rated push-on/thread-off cover,
respectively. When the F1FR56-300 Horizontal Sidewall is or-
dered with the F2 escutcheon the escutcheon assembly is
shipped separately and requires assembly of the collar at the
time of installation (Ref. Figure 5).
Apply a PTFE thread sealant to the sprinkler threads. After
a 25/8” (67mm) diameter hole is cut in the wall, the sprinkler
is easily installed with the Model GFR2 Wrench. To install
the sprinkler, remove the protective cap and then position the
wrench into the sprinkler/cup assembly until the wrench fully
engages the flats of the sprinkler. Then tighten the sprinkler
into the pipe fitting. When inserting or removing the wrench
from the sprinkler/cup assembly, care should be taken to pre-
vent damage to the sprinkler. DO NOT WRENCH ON ANY
OTHER PART OF THE SPRINKLER.

Protective plastic caps must be replaced on sprinklers after
they are installed and must remain on sprinklers until cov-
ers or escutcheons are installed. The escutcheon or cover-
plate assembly is installed by either pushing or threading into
the cup. FP escutcheons and cover assemblies provide ½”
(13mm) of adjustment. Final adjustment is made by turning
clockwise until the flange makes full contact with the wall sur-
face. Escutcheon or cover removal requires turning in the
counter- clockwise direction.
Covers and recessed escutcheons described in this bul-
letin are listed only for use with specific sprinklers. The use of
any other cover or escutcheon, with the Model F1FR56-300
Horizontal Sidewall Sprinkler or the use of the cover assem-
bly or escutcheons on any sprinkler with which they are not
specifically listed will void all guarantees, warranties, listings
and approvals.
When installing Model F1FR56-300 Horizontal Sidewall
sprinklers with raised escutcheons use a Model W2 wrench.
The protective plastic wraps on these sprinklers should re-
main on them throughout the installation. When the sprinkler
system is placed in service, the wraps must be removed.
Maintenance
Model F1FR56-300 Series Sprinklers should be inspected
and the sprinkler system maintained in accordance with
NFPA 25. Do not clean sprinklers with soap and water, am-
monia or any other cleaning fluids. Remove dust by using a
soft brush or gentle vacuuming. Remove any sprinkler that
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 sprin-
klers. 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.
