Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
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.

General
Description
The TYCO Model SW-20 and SW-24,
11.2 K-factor, Extended Coverage Ordi-
nary Hazard (ECOH) Horizontal Side-
wall Sprinklers, Standard Response
are decorative glass bulb sprinklers
designed for use in ordinary hazard
occupancies per NFPA 13.
The SW-20 provides protection of cov-
erage areas up to 16 ft x 20 ft (320 ft
2
),
whereas the SW-24 provides protec-
tion of coverage areas up to 16 ft x 24
ft (384 ft
2
), as compared to standard
coverage horizontal sidewall sprinklers
having a maximum coverage area of 10
ft x 10 ft (100 ft
2
) for ordi nary hazard
occupancies.
Horizontal sidewall sprinklers are
designed for installation along a wall
or the side of a beam and are com-
monly used instead of pendent or
upright sprinklers due to aesthetics or
building construction considerations,
where piping across the ceiling is not
desirable.
Corrosion resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently,
it is recommended that the end user
be consulted with respect to the suit-
ability of these corrosion resistant
coatings for any given corrosive envi-
ronment. The effects of ambient tem-
perature, concentration of chemicals,
and gas/chemical velocity, should be
con sidered, as a minimum, along with
the corrosive nature of the chemical to
which the sprinklers will be exposed.
NOTICE
The Model SW-20 and SW-24 Sprin-
klers described herein must be installed
and maintained in compliance with this
document and with the applicable stan-
dards of the National Fire Protection

diction. Failure to do so may impair the
performance of these devices.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.

any questions.
