Product Description
Reliable Models F1FR56 QREC and F1FR56 QREC
Recessed Sprinklers are quick response sprinklers which
combine the durability for a standard sprinkler with the
attractive 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 response sprinklers of the same
temperature rating.
Model F1FR56 QREC Quick Response Extended
Coverage Concealed Sprinkler is an attractive, low profile
concealed sprinkler assembly. This sprinkler assembly
utilizes 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 inlet 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 temperature classification
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 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
precisely manufactured glass capsule. This glass bulb is
specially 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
exercised 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 sprinklers are intended for installation as
specified in NFPA 13.
Installation
Quick response sprinkler are intended for installation
as specified in NFPA 13. Quick response sprinklers and
standard 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 negate 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 Sprinkler 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
Sprinklers with a threaded Model CCP cup which
is factory attached 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
positive pressure in the space above.
The sprinkler cup is factory attached to the Model
F1FR56 QREC Sprinkler. A PTFE based thread sealant
should be applied to the sprinkler threads only.
After a 25/8(67mm) inch diameter hole is cut in the
ceiling, 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
sprinkler/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.

Ordering Information
Specify:
1. Sprinkler Model: F1FR56 QREC
2. Sprinkler Type
3. Temperature Rating
4. Sprinkler Finish
5. Sprinkler Thread Type: [½” NPT] [ISO 7-1R½]
6. Escutcheon Finish (where applicable)
7. Coverplate Finish (where applicable)
8. Coverplate Temperature Rating
Note: When Model F1FR56 QREC Recessed sprinklers are ordered,
the sprinklers, escutcheons and coverplates are packaged
separately.
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
concealed cover plate/cup assembly with the Model
F1FR56 QREC Pendent Sprinkler or the use of the Model
CCP concealed 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 approvals.
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
Recessed 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. Remove 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.
