Extended Coverage Ordinary Hazard
Horizontal Sidewall Sprinklers (Standard Response)
General
Description
The TYCO Model SW-20 and SW-24,
11.2 K-factor, Extended Coverage Ordi-
nary Hazard (ECOH) Horizontal Sidewall
Sprinklers, Standard Response are dec-
orative 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 pro-
tection of coverage areas up to 16 ft. x
24 ft. (384 ft ), as compared to standard
2
coverage horizontal sidewall sprinklers
having a maximum coverage area of 10
ft. x 10 ft. (100 ft ) for ordi nary hazard
2
occupancies.
Horizontal sidewall sprinklers are de-
signed for installation along a wall or
the side of a beam and are common-
ly used instead of pendent or upright
sprinklers due to aesthetics or building
construction considerations, where pip-
ing 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 ob-
tained when exposed to corrosive at-
mospheres. Although corrosion resis-
tant coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
IMPORTANT
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 in-
stallation 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.

rosive atmospheres. Consequently, it
is recommended that the end user be
consulted with respect to the suitability
of these corrosion resistant coatings for
any given corrosive environment. The
effects of ambient temperature, con-
centration of chemicals, and gas/chemi-
cal velocity, should be con sidered, as a
minimum, along with the corrosive na-
ture of the chemical to which the sprin-
klers will be exposed.
NOTICE
The Model SW-20 and SW-24 Sprin-
klers described herein must be installed

document and with the applicable stan-
dards of the National Fire Protection As-
sociation, in addition to the standards
of any authorities having jurisdiction.
Failure to do so may impair the perfor-
mance of these devices.
The owner is responsible for maintain-
