General
Description
TYCO Model ESFR-22 Pendent Sprin-
klers are Early Suppression, Fast
Response Sprinklers having a nominal
K-factor of 22�4, see 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-22 Sprinklers are pri-
marily used for ceiling-only sprinkler
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 rub-
ber tires, roll paper, flammable liq-
uids, and aerosols
For more specific criteria, see Table
A as well as the applicable design
standard�
The Model ESFR-22 can protect a
storage arrangement of 40 ft (12,2 m)
with a ceiling height of 45 ft (13,7 m)
without requiring in-rack sprinklers�
In addition, it can be installed with a
maximum deflector-to-ceiling distance
of 18 in� (460 mm)�
IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to

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.
