General
Description
The Model ESFR-17 Sprinklers (Ref.
Figure 1) are “Early Suppression
Fast Response Sprinklers” having a
nominal K-factor of 16.8. They are
suppression mode sprinklers, and
their use is especially advantageous
as a means of eliminating the use of
in-rack sprinklers, when protecting
high-piled storage.
The Model ESFR-17 is primarily de-
signed for use in ceiling only sprin-
kler systems (i.e. no in-rack sprin-
klers) for the protection of storage
heights of most encapsulated or non-
encapsulated common materials in-
cluding cartoned unexpanded plas-
tics of up to 35 ft. (10,7 m) and with
ceiling heights of up to 40 ft. (12,2
m), as well as cartoned expanded
plastics of up to 25 ft. (7,6 m) with
ceiling heights of up to 30 ft.(9,1 m).
In addition, the protection of some
storage arrangements of roll paper
and rubber tires can be considered
as well.
Also, in some cases, the Model
ESFR-17 can be used to protect stor-
age heights up to 40 ft. (12,2 m) with
ceiling heights up to 45 ft. (13,7 m)
in combination with one level of in-
rack sprinklers.
The ESFR-17 provides the system
designer with hydraulic options not
presently available to the traditional
ESFR sprinklers having a nominal
K-Factor of 14.0. In particular, the
Model ESFR-17 has been designed
to operate at substantially lower end
head pressures, as compared to
ESFR sprinklers having a nominal
K-Factor of 14.0. This feature offers
flexibility when sizing the system pip-
ing, as well as possibly reducing or
eliminating the need for a system fire
pump.
Operation. The fusible link assembly
is comprised of two link halves which
are joined together by a thin layer of
solder. When the rated temperature
is reached, the solder melts and the
two link halves separate, which then
allows the sprinkler to activate and
flow water.
WARNINGS
The Model ESFR-17 Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the appli-
cable standards of the National Fire

Global). Failure to do so may impair
the integrity of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. The installing contractor or
sprinkler manufacturer should be
contacted relative to any questions.
