IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Construction (See Figure 1)
The inlet nipple is mild steel, and
the exible hose is SS AISI 304. The
connection at each end of the ex-
ible hose utilizes a brass slip nut,
NBR/CR O-ring, and Nylon W6 washer.
The sprinkler reducer is mild steel. The
reducer bracket, bar xing clamps, and
support bar are pressed steel.
General
Description
The TYCO FASTFLEX Flexible Sprinkler
Hose is a unique sprinkler drop assem-
bly comprised of a branchline adapter
nipple, stainless steel exible hose with
two slip nuts, sprinkler reducer, and
lightweight ceiling bracket components
as shown in Figure 1.
The flexible hose can be installed
in false ceilings without cutting and
threading pipes associated with
installing a drop, armover, and elbows.
FASTFLEX makes it possible to test
and charge the system with water
before the ceiling grid is installed.
Once the ceiling grid is in position, the
exible hose can be reshaped to suit
the final sprinkler location without
draining the system.
The exible hose is installed quickly
without large and expensive tools. Ideal
projects are ofces, schools, libraries,
hospitals, and shopping complexes.
The hose is for use on wet pipe, pre-
action, and dry-pipe systems. The hose
can also be used in conjunction with
ultra-low ow water mist nozzles fol-
lowing the design criteria outlined in
this technical data sheet.
NOTICE
FASTFLEX Flexible Sprinkler Hoses
described herein must be installed
and maintained in compliance with
this document and with the applicable
standards recognized by the Approval
agency, in addition to the standards of
any other authorities having jurisdiction.
Failure to do so may impair the perfor-
mance of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

TABLE A
FASTFLEX SPRINKLER HOSE ASSEMBLY
MODELS, ASSEMBLY LENGTHS, AND APPROVALS

TFP720
Page 7 of 8
Installation
The TYCO FASTFLEX Flexible Sprin-
kler Hose, as shown in Figure 1, must
be installed in accordance with this
section as follows:
NOTICE
FASTFLEX Flexible Sprinkler Hoses
are intended only to connect sprin-
klers directly to system piping as
shown in Figure 1. FASTFLEX Sprin-
kler Hoses cannot be joined together
to form longer hoses. Joining flexible
hoses together creates an assembly
with unknown performance that has
not been accounted for in system cal-
culations or safe product performance.
Step 1. Review the Design Criteria
section that applies to the Approval
agency recognized by the authority
having jurisdiction, as well as Figure 3
that provides installation guidance.
Step 2. Determine the approximate
place where the sprinkler will be
located. The support bar is 700 mm
long and shall be mounted on the
600 mm width of the ceiling grid. The
sprinkler should be located as close as
possible to the center of the distance
between ceiling grid T-bars.
Step 3. Slide the reducer bracket onto
the support Bar. Loosely attach the
reducer bracket and the two bar xing
clamps on the support bar and place
the bar xing clamps such that the
support bar crosses the location where
the sprinkler will be located.
Step 4. Attach one end of the ex-
ible hose onto the sprinkler reducer.
Applying the wrench to the slip nut,
and not to the exible hose, tighten to
a maximum torque of 35 N·m.
Step 5. Attach the inlet nipple on to the
branch line. Ensure that the arrow is in
the appropriate direction of ow to the
sprinkler and to use pipe thread sealant
at the connection to the branchline.
Attach one end of the exible hose on
to the inlet nipple. Applying the wrench
to the slip nut, and not to the exible
hose, tighten to a maximum torque of
35 N·m. Do not twist the exible hose.
Step 6. Bend the exible hose into
a curve(s) that locates the sprinkler
reducer at the other end of the exible
hose in the area where the sprinkler will
be located. The tube arc should not be
twisted, and the arc should be as large
and smooth as possible.
NOTICE
For minimum bend criteria, refer to the
Design Criteria section that applies to
the Approval agency recognized by the
authority having jurisdiction.
A bend radius smaller than pro-
vided by the minimum bend criteria
may adversely effect the friction loss
specifications stated by the approval
laboratory.
For assembly lengths greater than
1800 mm, the exible hose shall be
supported to the structure to ensure
that the maximum unsupported length
does not exceed 1800 mm. In these
cases, it is recommended that the tube
be secured to a xed mounting point
every 600 mm, in order to provide a
more stable installation.
Step 7. Insert the sprinkler reducer
into the reducer bracket. Locate the
reducer bracket and sprinkler reducer
where the sprinkler will be, and loosely
tighten the buttery bolt on the reducer
bracket.
Step 8. Attach the sprinkler to the
sprinkler reducer. Put a wrench on
the sprinkler reducer to counteract
the tightening torque and prevent the
exible hose from twisting. Reference
the sprinkler manufacturer’s sprinkler
data sheet for appropriate sprinkler
tightening torque, sprinkler wrench,
and other guidance.
Step 9. Verify that the sprinkler reducer
is seated in the reducer bracket. Pre-
cisely locate the sprinkler in all three
axes in accordance with the sprinkler
manufacturer’s data sheet. Tighten the
buttery bolts on the bar xing clamps
and the reducer bracket. The tightening
torque for the bar xing clamp fastener
is 4,5 to 5,7 N·m, and the tightening
torque for the reducer bracket fastener,
is a minimum of 2,3 N·m.
Step 10. After tightening all the but-
tery bolts, verify that the sprinkler is
properly located in accordance with
the manufacture’s instructions. If not,
loosen the buttery bolts and readjust
as required.
Care and
Maintenance
The TYCO FASTFLEX Flexible Sprinkler
Hose must be maintained and serviced
in accordance with this section.
Before closing a re protection system
control valve for inspection or main-
tenance work on the re protection
system that it controls, permission to
shut down the effected re protection
system must rst be obtained from
the proper authorities and all person-
nel who may be affected by this action
must be notied.
After placing a re protection system
in service, notify the proper authorities
and advise those responsible for moni-
toring proprietary and/or central station
alarms.
The owner is responsible for the inspec-
tion, testing, and maintenance of their
re protection system and devices in
compliance with this document, as well
as with the applicable standards of the
authorities having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualied Inspec-
tion Service in accordance with local
requirements and/or national codes.
