Description
TYCO Model ESFR-17 Pendent Sprin-
klers are Early Suppression, Fast
Response (ESFR) sprinklers having a
nominal K-factor of 16.8 (Ref. Figure 1).
They are suppression mode sprinklers
that are especially advantageous as a
means of eliminating in-rack sprinklers
when protecting high-piled storage.
Model ESFR-17 Pendent Sprinklers are
primarily used for ceiling-only sprinkler
protection of (but not limited to) the fol-
lowing storage applications:
• most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics
• cartoned, expanded plastics
• uncartoned, unexpanded plastics
• uncartoned, expanded plastics
• some storage arrangements of
rubber tires, roll paper, and aerosols
For more specific criteria, refer to Table
A in this technical data sheet as well as
the applicable design standard.
The Model ESFR-17 Pendent Sprin-
klers provide the system designer
with hydraulic and sprinkler place-
ment options not presently available
to traditional ESFR Sprinklers having

compared to ESFR Sprinklers having
a nominal K-factor of 14.0. This feature
offers flexibility when sizing system
piping, as well as possibly reducing or
eliminating the need for a system fire
pump.
Applications for the ESFR-17 Pendent
Sprinklers are expanding beyond cur-
rently recognized installation stan-
dards. For information on research fire
tests (with flammable liquids and aero-
sols, for example) that may be accept-
able to an authority having jurisdiction,
contact Technical Services.
WARNING
Orange protector must NOT be
removed until sprinkler is to be placed
in service. The W-Type 35 Sprinkler
Wrench MUST be used for proper
installation of the sprinkler. Failure to
do so may result in equipment damage
or failure.
