General
Description
The TYCO Model ESFR-17 Pendent
Sprinklers are Early Suppression, Fast
Response (ESFR) sprinklers with a
nominal K-factor of 16.8. The sprinkler
assembly is shown in 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 rub-
ber tires, roll paper, and aerosols
For more specific criteria, see Table A
and 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
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.
