Early Suppression, Fast Response
General
Description
TYCO Model ESFR-17 Pendent Sprin-
klers are Early Suppression, Fast
Response (ESFR) sprinklers having a
nominal K-factor of 16.8 (Ref. Figures
1 and 2). They are suppression mode
sprinklers that are especially advanta-
geous 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
1 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
a nominal K-factor of 14.0. In particu-
lar, Model ESFR-17 Pendent Sprinklers
are designed to operate at substan-
tially lower-end head pressures, as

Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

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,
