Model ESFR-17
Early Suppression Fast Response Pendent Sprinklers
16.8 K-factor
General
Description
The Model ESFR-17 Sprinklers (Ref.
Figure 1) are "Early Suppression Fast
Response Sprinklers" having a nomi-
nal K-factor of 16.8. They are suppres-
sion mode sprinklers, and they are es-
pecially advantageous as a means of
eliminating in-rack sprinklers, when
protecting rack storage.
The Model ESFR-17 is primarily de-
signed for use in ceiling only sprinkler
systems (i.e. no in-rack sprinklers) for
the protection of storage heights of
most encapsulated or non-encapsu-
lated common materials including car-
toned unexpanded plastics of up to 35
ft. (10,7 m) with ceiling heights to 40 ft.
(12,2 m), as well as cartoned ex-
panded plastics up to 25 ft. (7,6 m) with
ceiling heights to 30 ft.(9,1 m). In addi-
tion, the protection of some storage
arrangements of roll paper and rubber
tires can be considered.
In some cases, the Model ESFR-17
can be used to protect storage heights
up to 40 ft. (12,2 m) with ceiling heights
to 45 ft. (13,7 m) in combination with
one level of in-rack sprinklers.
The ESFR-17 provides the system de-
signer with hydraulic options not pres-
ently available to 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 pres-
sures, as compared to ESFR sprin-
klers having a nominal K-Factor of
14.0. This feature offers flexibility when
sizing the system piping, as well as
possibly reducing or eliminating the
need for a system fire pump.
WARNINGS
The Model ESFR-17 Sprinklers de-
scribed herein must be installed and
maintained in compliance with this

ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.

Operation
The fusible link assembly is comprised
of two link halves that are joined to-
gether by a thin layer of solder. When
the rated temperature is reached, the
solder melts and the two link halves
separate activating the sprinkler and
allowing water to flow.
