Product Description
Reliable Model F1 FR series sprinklers
are quick -response automatic sprin-
klers with a glass bulb thermal element.
Model F1 FR series sprinklers are Stan-
dard Spray sprinklers, with the excep-
tion of the Model F1 FR56 Conventional XLH Recessed
sprinkler which is an Old-style/Conven- Pendent FP
tional sprinkler.
The Model F1 FR Series automatic sprinklers utilize a 3.0
mm frangible glass bulb. These sprinklers have demonstrat-
ed response times in laboratory tests which are five to ten
times faster than standard response sprinklers. This quick
response enables the Model F1 FR Series sprinklers to apply
water to a fire faster than standard -response sprinklers of the
same temperature rating.
The glass bulb consists of an accurately controlled amount
of special fluid hermetically sealed inside a precisely man-
ufactured glass capsule. This glass bulb is specially con-
structed to provide fast thermal response.

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 liq-
uid 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 distrib-
ute the discharging water.
Model F1 FR Series sprinklers provide a wide range of op-
tions 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
Bulletin for information on the approvals and availability of
specific Model F1 FR series sprinkler configurations.
Model F1 FR Recessed Pendent and Recessed Horizon-
tal Sidewall sprinklers are required to be used with Reliable
Model F1, F2, or FP recessed escutcheons. See the Re-
cessed Escutcheon Data table in this Bulletin for listing and
approval information with each specific Model F1 FR 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 cov-
er 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 In-
stallation Information and Listed and Approved Temperature
Ratings tables in this Bulletin for further information on ap-
proved cover plate options.
Application
Model F1 FR Series sprinklers are intended for use in
accordance with NFPA 13, FM Property Loss Prevention
Data Sheets, and the requirements of the Authority Hav-
ing Jurisdiction. Care must be exercised that the k-factor,
temperature rating, deflector style, and sprinkler type are
in accordance with the requirements of the applicable
design and installation standards. In addition, Model
F1 FR Series sprinklers must be used in accordance with
their listings and approvals, as well as the information
provided in this Bulletin.
Installation
Glass bulb sprinklers have orange bulb protectors or pro-
tective caps to minimize bulb damage during shipping, han-
dling and installation. Reliable sprinkler installation wrench-
es are designed to install sprinklers with bulb protectors in
place. Remove the bulb protector at the time when the sprin-
kler system is placed in service for fire protection. Removal
of the bulb protector before this time may leave the bulb vul-
nerable to damage. Remove bulb protectors by undoing the
clasp by hand. Do not use tools to remove bulb protectors.
Model F1 FR Series sprinklers must be installed with the
Reliable 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 FR Series Recessed sprinklers are to be installed
as shown in Fig. 1, Fig. 2, or Fig. 3, as applicable to the spe-
cific 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 FR Series
Recessed sprinkler. The use of any other recessed escutch-
eon will void all approvals and negate all warranties.
Concealed Sprinklers
Model F1 FR 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 factory -installed Model CCP cup. A protective cap is in-
stalled 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 assemblies are joined using
a cover plate skirt with flexible tabs for threaded engage-
ment. 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 FR Series Concealed
Pendent sprinklers in ceilings which have positive pressure
in the space above.
Model F1 FR Series Concealed Pendent sprinklers require a
2-5/8-inch (67mm) diameter hole to be cut in the ceiling. The
Model RC1 wrench is used to engage the sprinkler wrenching
surfaces 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 remov-
ing the wrench from the sprinkler/cup assembly, care should be
taken to prevent damage to the sprinkler. Do not wrench any
other part of the sprinkler/cup assembly. Installation is com-
pleted 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 specifically listed my prevent good fire protection and
will void all guarantees, warranties, listings and approvals.

Maintenance
The Model F1 FR 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 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.

Sprinkler Connections
cULus Listed, FM Approved
Product Description
RASCOFLEX° Sprinkler Connections are intended to connect
a branch line to a sprinkler using a flexible stainless steel hose
assembly. RASCOFLEX® 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 stain-
less steel flexible sprinkler system complete with hose, branch
line connection, and sprinkler connection, as well as the pre -as-
sembled bracket assembly to attach to the ceiling.
