General
Description
TYCO Model ESFR-22 Pendent Sprin-
klers are Early Suppression, Fast
Response Sprinklers having a nominal
K-factor of 22.4 (Ref. to 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
rubber tires, roll paper, flammable
liquids, and aerosols
For more specific criteria, refer to Table
1 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 inches (460 mm).
