General
Description
TYCO Model FH-1 Flexible Hose can be
used in wet sprinkler systems between
the branchline and sprinkler when
installed in accordance with NFPA 13,
13D, and 13R. Flexible Hose provides
a unique sprinkler drop assembly com-
prised of the following components:
• Stainless steel flexible hose with
two slip nuts
• Branchline inlet nipple
• Straight sprinkler reducer
• Reducer bracket, bar fixing clamps,
and support bar
Using Model FH-1 Flexible Hose saves
time and cost because the system can
be installed in false ceilings without
cutting and threading pipes associ-
ated with installing a drop, arm-over,
and elbows. Model FH-1 Flexible Hose
makes it possible to test and charge
the system with water before installing
the ceiling grid. After the ceiling grid
is in position, the Model FH-1 Flexible
Hose can be reshaped to suit the final
sprinkler location without draining the
system.
Model FH-1 Flexible Hose is installed
quickly without large and expensive
tools. Ideal applications include offices,
schools, libraries, hospitals, and shop-
ping complexes.
