with pendent sprinklers. The following
paragraph provides the design criteria
unique to VdS Approval listing.
VdS Listing Design Criteria
• Wet-pipe systems only

General
Description
The TYCO FASTFLEX Model FB Flex-
ible Braided Hose is a unique sprinkler
drop assembly comprised of a stainless
steel exible hose a swivel inlet nipple,
a sprinkler reducer, and lightweight
ceiling bracket components. (Refer to
Figure 1.)
The FASTFLEX Model FB Flexible
Braided Hose can be installed in false
ceilings without cutting and thread-
ing pipes associated with installing a
drop, arm-over, and elbow. It provides
easier maneuverability around ducts
and trays in congested spaces and for
unusual ceiling types and curved plas-
terboard ceilings. The FASTFLEX Model
FB Flexible Braided Hose makes it pos-
sible to test and charge the system with
water before the ceiling grid is installed.
Once the ceiling grid is in position, the
hoses can be reshaped to suit the nal
sprinkler location without draining the
system.
The FASTFLEX Model FB Flexible
Braided Hose hoses are for use on wet
pipe sprinkler systems only.
NOTICE
The TYCO FASTFLEX Model FB Flexible
Braided Hose 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.
Approved Ceiling Systems
FASTFLEX Model FB Flexible Braided
Hose is approved for use only in the
following manufacturers suspended
ceilings listed below on the condition
that the prole is based on a T-shaped
prole:
AMF

VdS Friction Loss
For compensation of pressure
loss, the nominal assembly length
is to be multiplied by 10. The re-
sulting length will provide pressure
drop in equivalent length DN25
(33,7 x 3,25 mm) metal tube per EN
10255.
• Add 2,3 m when using a 90° sprin-
kler reducer.

Installation
The TYCO FASTFLEX Model FB
Flexible Braided Hose, as shown in
Figure 1, must be installed in accor-
dance with this section.
NOTICE
Flexible Braided Hoses are intended
only to connect sprinklers directly to
system piping (refer to Figure 1). Flex-
ible 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 approximately where
the sprinkler will be located. Mount the
End Brackets to the Support Bar then
slide the End Brackets over the ceiling
grid T-bars. The sprinkler should be
located as close to the center of the dis-
tance between the ceiling grid T-bars
as possible.
Step 3. Hand-tighten the Wings Screws
and the Hex Screws on the End Brack-
ets securing the Support Bar.
Step 4. Attach the Swivel Inlet Nipple
to the Branchline Fitting outlet. (Refer
to Figure 1.) Apply the wrench directly
to the Swivel Inlet Nipple and tighten to
the maximum torque of 35 Nm.
Step 5. Attach the sprinkler to the
Sprinkler Reducer. Place a wrench on
the Sprinkler Reducer to counteract
the tightening torque of the sprinkler
and torque the sprinkler to the recom-
mended torque setting. Refer to the
sprinkler manufacturer’s sprinkler data
sheet for appropriate sprinkler torque
setting, sprinkler wrench, and other
guidance.
Step 6. Bend the Flexible Hose and
place the Sprinkler Reducer to where
the sprinkler will be located. The hose
arc should not be twisted, and the arc
should be as large and smooth as pos-
sible. (Refer to Figures 2 and 3.)
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.
Step 7. Slide the Reducer Bracket over
the Sprinkler Reducer end of the Flex-
ible Sprinkler Hose and clip over the
Support Bar. Hand-tighten the fastener
on the Reducer Bracket securing the
Reducer Bracket to the Support Bar.
Ensure that the Reducer Bracket fas-
tener is secured to the at surface of
the Sprinkler Reducer.
Step 8. After tightening the Reducer
Bracket fastener, verify that the sprin-
kler is properly located in accordance
with the manufacturer’s instructions.
If not in the proper location, adjust its
position as necessary.
Step 9. Once the sprinkler is in the
proper location, torque all hardware as
follows:
