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 com-
ponents. (Ref. Figure 1.)
The FASTFLEX Flexible Sprinkler Hose
can be installed in false ceilings without
cutting and threading pipes associ-
ated with installing a drop, armover,
and elbows. FASTFLEX 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
FASTFLEX hoses can be reshaped to
suit the final sprinkler location without
draining the system.
FASTFLEX Flexible Sprinkler Hose
is installed quickly without large and
expensive tools. Ideal projects are
offices, schools, libraries, hospitals,
and shopping complexes. FASTFLEX
sprinkler hoses are for use on wet pipe,
preaction, and dry pipe systems. The
FASTFLEX hose can also be used in
conjunction with ultra-low flow water
mist nozzles following the design crite-
ria outlined in this technical data sheet.
NOTICE
The 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.
