General
Description
The TYCO Model ESFR-22 22.4 K-Fac-
tor Pendent Rapid Install Sprinkler
(RIS), herein called the ESFR-22 RIS,
is an Early Suppression, Fast Response
(ESFR) sprinkler with a pre-installed
rubber RIS gasket for quick and easy
installation. The ESFR-22 RIS threads
into a TYCO RIS welded fitting by hand
without the need for tape or sealant.
The sprinkler assembly is shown in
Figure 1.

The ESFR-22 RIS is a suppression-
mode sprinkler that is especially advan-
tageous as a means of eliminating the
use of in-rack sprinklers when protect-
ing high-piled storage.
The ESFR-22 RIS sprinkler is primarily
used for ceiling-only sprinkler protec-
tion 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 the
National Fire Protection Association
(NFPA) standard 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 ESFR-22 RIS provides the system
designer with hydraulic and sprinkler
placement options not presently avail-
able to the traditional ESFR sprinklers
with nominal K-factors of 14.0 and
16.8. In particular, the ESFR-22 RIS is
designed to operate at substantially
lower-end head pressures, as com-
pared to ESFR sprinklers with nominal
K-factors of 14.0 and 16.8. This feature
offers flexibility when sizing system
piping, as well as possibly reducing or
eliminating the need for a system fire
pump.
The ESFR-22 RIS can eliminate the use
of in-rack sprinklers when protecting
high-piled storage of specific materi-
als 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.
