General
Description
The Model ESFR-1 Sprinklers (Ref.
Figure 1) are “Early Suppression Fast
Response Sprinklers” having a nomi-
nal K-factor of 14.0. They are suppres-
sion mode sprinklers, and their use is
especially advantageous as a means
of eliminating the use of in-rack sprin-
klers, when protecting high-piled stor-
age.
The Model ESFR-1 is primarily de-
signed for use with storage of most
encapsulated or non-encapsulated
common materials including cartoned
unexpanded plastics to 35 ft. (10,7 m)
high. In addition, the protection of
some storage arrangements of roll pa-
per and rubber tires can be consid-
ered.
Applications for the Model ESFR-1
Sprinklers are expanding beyond the
current recognized installation stand-
ards. For information regarding re-
search fire tests that may be accept-
able

Having
Jurisdiction (e.g., flammable liquids,
aerosols, etc.), please contact the
