Product Description
Reliable Models F1FR56 QREC and F1FR56 QREC Re-
cessed Sprinklers are quick response sprinklers which
combine the durability for a standard sprinkler with the at-
tractive low profile of a decorative sprinkler.
The Models F1FR56 QREC and F1FR56 QREC Recessed
Automatic Sprinklers utilize a 3.0mm frangible glass bulb.
These sprinklers have demonstrated response times in
laboratory tests which are five times faster than standard
response sprinklers. This quick response enables these
sprinklers to apply water to a fire faster than standard re-
sponse sprinklers of the same temperature rating.
Model F1FR56 QREC Quick Response Extended Cover-
age Concealed Sprinkler is an attractive, low profile con-
cealed sprinkler assembly. This sprinkler assembly uti-
lizes a Model F1FR56 QREC pendent sprinkler in a Model
CCP cup and push-on thread-off cover plate assembly.
The cup is securely factory threaded on the sprinkler’s in-
let end. The assembly is shipped with a protective cap.
The sprinkler and cup are easily installed into the sprinkler
fitting using the Model GFR2 Sprinkler Wrench. The cover
plate assembly is attached to the sprinkler cup using a
flexible tooth threaded engagement. The cover plate is
attached to the skirt using 135°F (57°C) ordinary tempera-
ture classification solder.

Coverage Pendent F1/F2

When the ceiling temperature rises, the solder holding
the cover plate melts, allowing the release of this part and
thus exposing the Model F1FR56 QREC sprinkler inside to
the rising ambient temperature.
The Temperature rating of the sprinkler identified by the
color of the glass bulb.
The glass bulb consists of an accurately controlled
amount of special fluid hermetically sealed inside a pre-
cisely manufactured glass capsule. This glass bulb is spe-
cially constructed to provide fast thermal response.
Application
Quick response sprinklers are used in fixed fire protection
systems: Wet, Dry, Deluge or Preaction. Care must be exer-
cised that the orifice size, temperature rating, deflector style
and sprinkler type are in accordance with the latest published
standards of the National Fire Protection Association or the
approving authority having jurisdiction. Quick response sprin-
klers are intended for installation as specified in NFPA 13.

Installation Aid:
A protective cap is included for use during installation.
Installation
Quick response sprinkler are intended for installation as
specified in NFPA 13. Quick response sprinklers and stan-
dard response sprinklers should not be intermixed.
The Model F1FR56 Recessed QREC Sprinklers are to be
installed as shown. The Model F1, F2 or FP Escutcheons
illustrated are the only recessed escutcheons to be used
with the Model F1FR56 QREC Sprinklers. The use of any
other recessed escutcheon will void all approvals and ne-
gate all warranties.
When installing Model F1FR56 QREC Sprinklers, use the
Model D Sprinkler Wrench or Model W2 Sprinkler Wrench.
When installing Model F1FR QREC Recessed Pendent or
Recessed Sidewall Sprinklers, use the Model GFR2 Sprin-
kler Wrench. Any other type of wrench may damage these
sprinklers.
Model F1FR56 QREC Concealed Sprinklers use 135°F
(57°C) or 155°F (68°C) Model F1FR QREC Pendent Sprin-
klers with a threaded Model CCP cup which is factory at-
tached to the sprinkler. The assembly is completed by the
installation of the attractive, low profile, 135°F (57°C) rated
cover plate assembly. The cover plate and sprinkler cup
are joined using a flexible tooth threaded engagement. A
choice of two cover plate assemblies provides either ½”
(13mm) or 5/8” (8mm) of cover adjustment.
Do not install these sprinklers in ceilings which have pos-
itive pressure in the space above.

separately.
should be applied to the sprinkler threads only.
After a 25/8(67mm) inch diameter hole is cut in the ceil-
ing, the sprinkler is easily installed with the Model GFR2
Wrench. When installing a sprinkler, the protective cap
is removed and the wrench is positioned into the sprin-
kler/cup assembly until the two wrench faces engage the
wrenching flats on the Model F1FR56 QREC Sprinkler.
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. The cover plate assembly is then
pressed into the cup. Final adjustment is made by turning
the cover plate until the skirt flange makes full contact with
the ceiling surface. 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 with specific sprinklers. The use of any other con-
cealed cover plate/cup assembly with the Model F1FR56
QREC Pendent Sprinkler or the use of the Model CCP con-
cealed cover plate assembly on any sprinkler with which
it is not specifically listed may prevent good fire protection
and will void all guarantees, warranties, listings and ap-
provals.
Glass bulb sprinklers have orange bulb protectors to
minimize bulb damage during shipping, handling and
installation. REMOVE THIS PROTECTION AT THE TIME
THE SPRINKLER SYSTEM IS PLACED IN SERVICE FOR
FIRE PROTECTION. Removal of the protectors before this
time may leave the bulb vulnerable to damage. RASCO
wrenches are designed to install sprinklers when covers
are in place. REMOVE PROTECTORS BY UNDOING THE
CLASP BY HAND. DO NOT USE TOOLS TO REMOVE
THE PROTECTORS.
Maintenance
The Models F1FR56 QREC and F1FR56 QREC Re-
cessed Sprinklers should be inspected and maintained in
accordance with NFPA 25. Do not clean sprinklers with
soap and water, ammonia or any other cleaning fluids. Re-
move dust by gentle vacuuming. Replace any sprinkler
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.
