General
Description
The TYCO Model ESFR-22 Pendent
Sprinklers are Early Suppression, Fast
Response (ESFR) sprinklers with a
nominal K-factor of 22�4� The sprinkler
assembly is shown in Figure 1� The
sprinklers' suppression-mode design is
especially advantageous as a means of
eliminating the use of in-rack sprinklers
when protecting high-piled storage�
The Model ESFR-22 Sprinklers are
primarily used for ceiling-only sprin-

kler protection of 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
Note: The sprinklers are not limited to
these storage applications.
For more specific criteria, see the Tech-
nical Data section, Table A, and the
applicable design standard�
The Model ESFR-22 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�

together by a thin layer of solder� When
the rated temperature is reached, the
solder melts and the two link halves
separate, activating the sprinkler and
flowing water�
