General
Description
The TYCO FASTFLEX Flexible Sprinkler
Hose is a unique sprinkler drop assem-
bly comprised of a branchline adapter
nipple, stainless steel flexible 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
flexible hose can be reshaped to suit
the final sprinkler location without
draining the system.
The flexible hose is installed quickly
without large and expensive tools. Ideal
projects are offices, 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 flow water mist nozzles fol-
lowing the design criteria outlined in
this technical data sheet.
