Product Description
RASCOFLEX° Sprinkler Connections are intended to connect
a branch line to a sprinkler using a flexible stainless steel hose
assembly. RASCOFLEXO Sprinkler Connections are suitable for
use in suspended and hard ceiling applications such as T-Bar
ceiling grids, wood, metal stud, or hat furring channel hard lid
ceilings. Every package contains one (1) fully assembled stainless
steel flexible sprinkler system complete with hose, branch
line connection, and sprinkler connection, as well as the pre -
assembled bracket assembly to attach to the ceiling.
RASCOFLEXO Sprinkler Connections are designed for use in
hydraulically calculated wet, preaction, or dry sprinkler systems
per NFPA 13, 13R, 13D, and FM Global Loss Prevention Data
Sheets.

Product Description
Reliable Model F1 FIR series sprinklers
are quick -response automatic sprinklers
with a glass bulb thermal element. Model
F1 FIR series sprinklers are Standard Spray
sprinklers, with the exception of the Model
F1 FR56 Conventional sprinkler which is XLH Recessed
an Old-style/Conventional sprinkler. Pendent FP
The Model F1 FR Series automatic sprinklers utilize a 3.0
mm frangible glass bulb. These sprinklers have demonstrated
response times in laboratory tests which are five to ten times
faster than standard response sprinklers. This quick response
enables the Model F1 FIR Series sprinklers to apply water to a
fire faster than standard -response sprinklers of the same tem-
perature rating.
The glass bulb consists of an accurately controlled amount
of special fluid hermetically sealed inside a precisely manufac-
tured glass capsule. This glass bulb is specially constructed to
provide fast thermal response.

Reliable Automatic Sprinkler Co., Inc., 103 Fairview Park Drive, Elmsford, New York 10523
At normal temperatures, the glass bulb contains the 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.
Model F1 FIR Series sprinklers provide a wide range of options
where quick -response, glass bulb sprinklers are used:
• Pendent, recessed pendent, upright, horizontal side -
wall, and vertical sidewall deflectors
• K-factors of 2.8 (40 metric), 4.0 (57 metric), 4.2 (60
metric), and 5.6 (80 metric)
• Flush, recessed, and concealed installations
See the Design and Installation Information table in this Bul-
letin for information on the approvals and availability of specific
Model F1 FIR series sprinkler configurations.
Model F1 FIR Recessed Pendent and Recessed Horizontal
Sidewall sprinklers are required to be used with Reliable Model
F1, F2, or FP recessed escutcheons. See the Recessed Es-
cutcheon Data table in this Bulletin for listing and approval infor-
mation with each specific Model F1 FIR series sprinkler. Model
F1 and F2 recessed escutcheons, shown in Fig. 1 and 3, are
a friction fit assembly allowing for 3/4-inch (19mm) and 1/2-
inch (12.7mm) of adjustment, respectively. Model FP recessed
escutcheons, shown in Fig. 2, provide a 1/2-inch (12.7mm)
threaded adjustment.
Model F1 FR56 Concealed Pendent and Model F1 FR56LL
Concealed Pendent sprinklers are required to be used with
Model CCP cover plates. A standard profile Model CCP cover
plate is available that provides up to 1/2-inch (12.7mm) of cover
plate adjustment. In addition, a low profile Model CCP cover
plate is also available that provides up to 5/16-inch (8.Omm) of
cover plate adjustment. See the Design and Installation Infor-
mation and Listed and Approved Temperature Ratings tables
in this Bulletin for further information on approved cover plate
options.
Application
Model F1 FIR Series sprinklers are intended for use in ac-
cordance with NFPA 13, FM Property Loss Prevention Data
Sheets, and the requirements of the Authority Having Juris-
diction. Care must be exercised that the k-factor, tempera-
ture rating, deflector style, and sprinkler type are in accor-
dance with the requirements of the applicable design and
installation standards. In addition, Model F1 FIR Series sprin-
klers must be used in accordance with their listings and ap-
provals, as well as the information provided in this Bulletin.
Installation
Glass bulb sprinklers have orange bulb protectors or protec-
tive caps to minimize bulb damage during shipping, handling
and installation. Reliable sprinkler installation wrenches are
designed to install sprinklers with bulb protectors in place. Re-
move the bulb protector at the time when the sprinkler system is
placed in service for fire protection. Removal of the bulb protec-
tor before this time may leave the bulb vulnerable to damage.
Remove bulb protectors by undoing the clasp by hand. Do not
use tools to remove bulb protectors.
Model F1 FIR Series sprinklers must be installed with the Reli-
able sprinkler installation wrench identified in the Design and
Installation Information table in this Bulletin. Any other wrench
may damage the sprinkler. A leak tight sprinkler joint can be
obtained with a torque of 8 to 18 lb-ft (11 to 24 N-m). Do not
tighten sprinklers over the maximum recommended installation
torque. Exceeding the maximum recommended installation
torque may cause leakage or impairment of the sprinkler.
Recessed Sprinklers
Model F1 FIR Series Recessed sprinklers are to be installed
as shown in Fig. 1, Fig. 2, or Fig. 3, as applicable to the specific
model being installed. The Recessed Escutcheon Data table in
the Bulletin identifies the only recessed escutcheons that are
permitted to be used with each Model F1 FIR Series Recessed
sprinkler. The use of any other recessed escutcheon will void all
approvals and negate all warranties.
Concealed Sprinklers
Model F1 FIR Series Concealed Pendent sprinklers are to
be installed as shown in Fig. 4 or Fig. 5, as applicable to the
selected cover plate. Model F1 FR56 Concealed Pendent and
Model F1 FR56LL Concealed Pendent sprinklers have a facto-
ry -installed Model CCP cup. A protective cap is installed at the
factory that should remain on the sprinkler until the sprinkler is
installed and should then be reinstalled on the sprinkler until the
cover plate is installed. The concealed sprinkler assemblies are
completed by the installation of a Model CCP push-on/thread-
off cover plate assembly. The cover plate and sprinkler cup as-
semblies are joined using a cover plate skirt with flexible tabs
for threaded engagement. A choice of two Model CCP cover
plate assemblies provides either 1/2-inch (13mm) or 5/8-inch
(8mm) of cover adjustment. Do not install Model F1 FIR Series
Concealed Pendent sprinklers in ceilings which have positive
pressure in the space above.
Model F1 FIR Series Concealed Pendent sprinklers require
a 2-5/8-inch (67mm) diameter hole to be cut in the ceiling. The
Model W4 wrench is used to engage the sprinkler wrenching sur-
faces and to install the sprinkler in the fitting. Remove the protective
cap to install the sprinkler, then reinstall the protective cap until the
cover plate is installed. When inserting or removing the wrench from
the sprinkler/cup assembly, care should be taken to prevent dam-
age to the sprinkler. Do not wrench any other part of the sprinkler/
cup assembly. Installation is completed by removing the protective
cap from the sprinkler and pushing the cover plate 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 the cover plate 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 concealed cover plate/
cup assembly other than the Reliable Model CCP with Model
F1 FR56 Concealed Pendent and Model F1 FR56LL Concealed
Pendent sprinklers or the use of the Model CCP Concealed
cover plate assembly on any sprinkler with which it is not spe-
cifically listed my prevent good fire protection and will void all
guarantees, warranties, listings and approvals.

Maintenance
The Model F1 FIR Series sprinklers should be inspected 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. 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 replace-
ment of damaged or operated sprinklers.
