General
Description
TYCO Model ESFR-17 Pendent Sprin-
klers are Early Suppression, Fast
Response (ESFR) sprinklers having a
nominal K-factor of 16.8 (See Figure 1).
They are suppression mode sprinklers
that are especially advantageous as a
means of eliminating in-rack sprinklers
when protecting high-piled storage.
The Model ESFR-17 Pendent Sprinklers
are available in two temperature ratings
and Listed or Approved accordingly;
155
°
F (68
°
C) is UL and C-UL Listed
and FM Approval; and 200
°
F (93
°
C) is
UL and C-UL Listing only.
Model ESFR-17 Pendent Sprinklers are
primarily used for ceiling-only sprinkler
protection of (but not limited to) the fol-
lowing storage applications:
• most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics
• cartoned, expanded plastics
• uncartoned, unexpanded plastics
• uncartoned, expanded plastics
• some storage arrangements of
rubber tires, roll paper, and aerosols
For more specific criteria, refer to Table
A in this technical data sheet as well as
the applicable design standard.
The Model ESFR-17 Pendent Sprin-
klers provide the system designer
with hydraulic and sprinkler place-
ment options not presently available
to traditional ESFR Sprinklers having
a nominal K-factor of 14.0. In particu-
lar, Model ESFR-17 Pendent Sprinklers
are designed to operate at substan-
tially lower-end head pressures, as
compared to ESFR Sprinklers having
a nominal K-factor of 14.0. This feature
offers flexibility when sizing system
piping, as well as possibly reducing or
eliminating the need for a system fire
pump.
Applications for the ESFR-17 Pendent
Sprinklers are expanding beyond cur-
rently recognized installation stan-
dards. For information on research fire
tests (with flammable liquids and aero-
sols, for example) that may be accept-
able to an authority having jurisdiction,
contact Technical Services.
WARNING
Orange protector must NOT be
removed until sprinkler is to be placed
in service. The W-Type 35 Sprinkler
Wrench MUST be used for proper
installation of the sprinkler. Failure to
do so may result in equipment damage
or failure.
NOTICE
The Model ESFR-17 Pendent Sprinklers
described herein must be installed and
maintained in compliance with this
document, as well as with the appli-
cable standards of the National Fire
Protection Association (NFPA), in addi-
tion to the standards of any authorities
having jurisdiction, such as FM Global.
Failure to do so may impair the perfor-
mance of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
In all cases, the appropriate NFPA or
FM Global installation standard, or
other applicable standard, must be ref-
erenced to ensure applicability and to
obtain complete installation guidelines.
The general guidelines in this technical
data sheet are not intended to provide
complete installation criteria.
