Model ESFR-17
Early Suppression Fast Response Pendent Sprinklers
16.8 K-factor
General
Description
The Model ESFR-17 Pendent 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 that
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 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 rubber tires, roll pa-
per, and aerosols 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
IMPORTANT
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 in-
stallation 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.

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.

The Model ESFR-17 Sprinklers de-
scribed herein must be installed and

ble standards of the National Fire Pro-

ure to do so may impair the perform-
ance of these devices.

ing their fire protection system and de-
vices in proper operating condition.
