Model ESFR-25
Early Suppression, Fast Response Pendent Sprinklers
25.2 K-Factor
General
Description
The TYCO Model ESFR-25 Pendent
Sprinklers are "Early Suppression,
Fast Response Sprinklers" having
a nominal K-Factor of 25.2. (Refer to
Figure 1.) They are suppression-mode
sprinklers that are especially advanta-
geous as a means of eliminating the
use of in-rack sprinklers when pro-
tecting high-piled storage.
The Model ESFR-25 Sprinklers are
primarily used for ceiling-only sprin-
kler protection of (but not limited to)
the following storage applications:
• Most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics.
• Uncartoned (exposed) expanded
plastics in accordance with NFPA
13 and FM Global standards.
• Some storage arrangements of
rubber tires, roll paper, flammable
liquids, aerosols, and automotive
components.
For more specific criteria, refer to
Table 1 in this data sheet as well as
the applicable design standard.
The Model ESFR-25
provide the system designer with
hydraulic and sprinkler placement
options not presently
to the traditional ESFR sprinklers
having nominal K-Factors of 14.0
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

and 16.8. In particular, the Model
ESFR-25 Sprinkler has been designed
to operate at substantially lower-end
head pressures, as compared to ESFR
Sprinklers having nominal K-Factors
of 14.0 and 16.8. This feature offers
flexibility when sizing system piping,
as well as possibly reducing or
eliminating the need for a system fire
pump.
Also, Model ESFR-25 Sprinklers per-
mit use of a maximum deflector-to-
ceiling distance of 18 inches (460 mm)
versus 14 inches (360 mm).
tionally, a storage arrangement of 40
ft. (12,2 m) with a ceiling height of 45
ft. (13,7 m) does not require in-rack
sprinklers as do other ESFR Sprinklers
having nominal K-Factors of 14.0. and
16.8.
Applications for the TYCO ESFR
Sprinklers are expanding beyond cur-
rently recognized installation stan-
dards. For information on research
fire tests (with flammable liquids and
aerosols, for example) that may be
acceptable to an Authority Having Ju-
risdiction, contact the Technical Ser-
vices department.
NOTICE
The Model ESFR-25 Sprinklers described
herein must be installed and maintained
in compliance with this document, as well
Sprinklers
as with the applicable standards of the
National Fire Protection Association, in
addition to the standards of any authorities
available
having jurisdiction (for example, FM
Global). Failure to do so may impair the
performance of these devices.
Owners are responsible for maintaining
their fire protection system and devices in
proper operating condition. The installing
contractor or sprinkler manufacturer
should be contacted with any questions.
In all cases, the appropriate NFPA or FM
installation standard, or other applicable
standard, must be referenced to ensure
applicability and to obtain complete
a sprin-
installation guidelines. The general
guidelines in this data sheet are not
intended to provide complete installation
criteria.
