Model ESFR-25 25.2 K-factor Pendent
Rapid Install Sprinkler
Early Suppression, Fast Response
General
Description
The TYCO Model ESFR-25 25.2 K-Fac-
tor Pendent Rapid Install Sprinkler
(RIS), herein called the ESFR-25 RIS,
is an Early Suppression, Fast Response
(ESFR) sprinkler with a pre-installed
rubber RIS gasket for quick and easy
Installation. The ESFR-25 RIS threads
into a TYCO RIS welded fitting by hand
without the need for tape or sealant.
The sprinkler assembly is shown in
Figure 1.
The ESFR-25 RIS is a suppression-
mode sprinkler that is especially advan-
tageous as a means of eliminating the
use of in-rack sprinklers when protect-
ing high-piled storage.
The ESFR-25 RIS sprinkler is primarily
used for ceiling-only sprinkler protec-
tion 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 the
National Fire Protection Association
(NFPA) standard NFPA 13 and FM
Global standards.
• Some storage arrangements of rub-
ber tires, roll paper, flammable liq-
uids, aerosols, and automotive
components
For more specific criteria, see Table B
and the applicable design standard.
IMPORTANT
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.

The ESFR-25 RIS provides the system
designer with hydraulic and sprinkler
placement options not presently avail-
able to the traditional ESFR sprinklers
with nominal K-factors of 14.0 and
16.8. In particular, the ESFR-25 RIS is
designed to operate at substantially
lower-end head pressures, as com-
pared to ESFR sprinklers with 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.
The ESFR-25 RIS can eliminate the use
of in-rack sprinklers when protecting
high-piled storage of specific materi-
als up to the following heights:
• NFPA: 40 ft (12,2 m) with ceilings up
to 45 ft (13,7m)
• FM: 45 ft (13,7 m) with ceilings up to
50 ft (15,2 m)
For more specific criteria, see Table B
and the applicable design standard.
The ESFR-25 RIS is listed by
Under writers
Laboratories
for specific applications with a
maximum storage height of 43 ft
(13,1 m) with a maximum ceiling height
of 48 ft (14,6 m) without the require-
ment for in-rack sprinklers. Refer to the

design criteria.
