Model ESFR-17
Early Suppression Fast Response Upright Sprinklers
16.8 K-factor
General
Description
The Model ESFR-17 Upright Sprin-
klers (Ref. Figure 1) are "Early Sup-
pression Fast Response Sprinklers"
having a nominal K-factor of 16.8. They
are suppression mode sprinklers, and
they are especially advantageous as a
means of eliminating in-rack sprin-
klers, 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 30
ft. (9,1 m) with ceiling heights to 35 ft.
(10,7 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.
The ESFR-17 Upright Sprinklers pro-
vide the system designer with an up-
right option over the traditional pen-
dent type ESFR sprinklers. The
offering of a 16.8 K-factor optimizes
hydraulic design when considering up-
right ESFR sprinklers. These features
offer flexibility when sizing the system
piping, as well as positioning the sys-
tem piping with respect to the ceiling.
WARNINGS
The Model ESFR-17 Upright Sprin-
klers described herein must be in-
stalled and maintained in compliance
with this document, as well as with the
applicable standards of the National
Fire Protection Association, in addition
to the standards of any other authori-

the integrity of these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.

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
Copper
solder melts and the two link halves
separate activating the sprinkler and
allowing water to flow.
