Tyco ESFR-17 Quick Start Manual

Model ESFR-17 Dry Type Pendent Sprinklers
Early Suppression Fast Response
16.8 K-factor
General
Description
The TYCO Model ESFR-17 Dry Type
Pendent Sprinklers (TY7229) are "Early
Suppression Fast Response Sprin-
klers" 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 Sprinkler
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
allowing for a pendent sprinkler instal-
lation 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 tempera-
tures. The water supply is provided
from a 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 Sprin-
klers, and substantially lowers the
end head pressure requirement as
compared to the 14.0 K-factor ESFR
Dry Type Pendent Sprinklers.
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
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.

Combining a 16.8 K-factor with a
dry type sprinkler design, the Model
ESFR-17 Dry Type Sprinklers 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 to seal the top and the bottom
of the clearance space where the
sprinkler drop protrudes through the
cold storage ceiling.
