Model SW-20 and SW-24 — 11.2 K-factor
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 Ordi­nary Hazard (ECOH) Horizontal Side­wall Sprinklers, Standard Response
are decorative glass bulb sprinklers
designed for use in ordinary hazard
occupancies per NFPA 13.

The SW-20 provides protection of cov­erage areas up to 16 ft x 20 ft (320 ft2),
whereas the SW-24 provides protec­tion of coverage areas up to 16 ft x 24
ft (384 ft2), as compared to standard
coverage horizontal sidewall sprinklers
having a maximum coverage area of 10
ft x 10 ft (100 ft2) for ordi nary hazard
occupancies.

Horizontal sidewall sprinklers are
designed for installation along a wall
or the side of a beam and are com­monly 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 atmo­spheres. Although corrosion resistant
coated sprinklers have passed the
standard corrosion tests of the appli­cable approval agencies, the testing is

not representative of all possible cor­rosive 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, 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 Sprin­klers described herein must be installed
and maintained in compliance with this
document and with the applicable stan­dards of the National Fire Protection
Association, in addition to the stan­dards of any authorities having juris­diction. Failure to do so may impair the
performance of these devices.

The owner is responsible for maintain­ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted with
any questions.

The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
