Model ESFR-17
16.8 K-factor Dry Type Pendent Sprinklers
Early Suppression, Fast Response
General
Description
TYCO Model ESFR-17 Dry Type
Pendent Sprinklers are Early Suppres-
sion, Fast Response (ESFR) 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 sprinklers
when protecting high-piled box-in-box
refrigerated storage areas.
The Model ESFR-17 Dry Type Pendent
Sprinkler is FM Approved and has
successfully undergone full-scale fire
testing at FM Global, when used in con-
formance with applicable FM Global
Property Loss Prevention Data Sheets.
The Model ESFR-17 Dry Type Sprin-
kler consists of an ESFR sprinkler per-
manently secured to a sprinkler drop
featuring an inlet with both grooved
and threaded connections. The drop
between the inlet and sprinkler remains
dry until the sprinkler operates, allow-
ing for a pendent sprinkler installa-
tion on a wet pipe sprinkler system
where the dry drop and sprinkler are
located in an area subjected to freezing
temperatures.
The Model ESFR-17 Dry Type Sprin-
klers are primarily used for ceiling only
sprinkler protection (i.e., no need for
in-rack sprinklers) and used to protect
solid piled, palletized, and rack storage
that is subject to freezing temperatures.
The water supply is provided from a

Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
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
installation 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.

wet pipe system located outside of the
refrigerated storage area. The Model
ESFR-17 Dry Type Sprinklers feature
all of the same design criteria as 16.8
K-factor ESFR Pendent Sprinklers, and
substantially lowers the end head pres-
sure requirement as compared to the
14.0 K-factor ESFR Dry Type Pendent
Sprinklers.
Combining a 16.8 K-factor with a
dry-type sprinkler design, the Model
ESFR-17 Dry Type Sprinkler provides
the system designer with features that
offer flexibility when sizing system
piping, as well as possibly reducing or
eliminating the need for a system fire
pump when protecting high-piled box-
in-box refrigerated storage areas.
The ESFR-17 Dry Type Sprinkler also
includes two Insulating Seal Assem-
blies that help seal the clearance space
around the sprinkler casing. The seal
assemblies are intended to slow the
exchange of air between the heated
area and the protected area to help
prevent humidity and temperature dif-
ferential in the area around the sprin-
kler. Condensation on the sprinkler and
subsequent ice buildup on or around
the sprinkler can occur that might
damage the sprinkler or prevent proper
operation in a fire situation.
To install the Insulating Seal Assem-
blies, follow the installation instruc-
tions in this data sheet. The Insulating
Seal Assemblies are recommended to
be installed on smooth, flat, and clean
surfaces. If it is expected that environ-
mental conditions may result in exces-
sive condensation, additional sealing of
the assembly is recommended.
There are specific situations, such as
corrugated surfaces where alternate
methods to seal the clearance hole are
recommended. For additional guid-
ance, contact Johnson Controls Tech-
nical Services.
