Model ESFR-25
25.2 K-factor Pendent Sprinkler
Early Suppression, Fast Response
General
Description
The TYCO Model ESFR-25 Pendent
Sprinklers are Early Suppression, Fast
Response (ESFR) sprinklers with a
nominal K-factor of 25.2. The sprinkler
assembly is shown in Figure 1. They are
suppression-mode sprinklers that are
especially advantageous as a means of
eliminating the use of in-rack sprinklers
when protecting high-piled storage.
The Model ESFR-25 Sprinklers are pri-
marily 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
• Uncartoned (exposed) expanded
plastics in accordance with 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.
The Model ESFR-25 Pendent Sprin-
klers provide the system designer
with hydraulic and sprinkler place-
ment options not presently available to
the traditional ESFR sprinklers having
nominal K-factors of 14.0 and 16.8. In
particular, the Model ESFR-25 Sprin-
kler is designed to operate at substan-
tially lower-end head pressures, as

nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

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 pos-
sibly reducing or eliminating the need
for a system fire pump.
The Model ESFR-25 Sprinklers can
eliminate the use of in-rack sprinklers
when protecting high-piled storage of
specific materials 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 Model ESFR-25 Sprinklers are
listed by Underwriters Laboratories
(UL) 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.
