General
Description
TYCO Series DS-1 Dry-Type Sprin-
klers, 5.6K Stainless Steel Pendent,
Horizontal Sidewall, Standard (5 mm
Bulb) and Quick (3 mm Bulb) Re-
sponse, Extended Coverage, are the
first stainless steel dry-type sprinklers
to be listed by UL and C-UL. With a
K-Factor of 5.6, these corrosion-resis-
tant automatic sprinklers can be used
in wet-pipe, dry-pipe, or preaction
systems.
These pendent and horizontal sidewall
sprinklers are available in a variety of
configurations to suit coverage type
and thermal sensitivity. Refer to the
Model/Sprinkler Identification Num-
bers (SINs) section for details.
Series DS-1 Stainless Steel Dry-Type
Sprinklers are typically used:
• where corrosive atmospheres exist;
for example, salt-water areas, park-
ing garages, chemical
areas, mechanical rooms, industrial
manufacturing sites, and software
chip washing facilities.
• on dry-pipe systems exposed to
freezing temperatures; for example,
sprinkler drops from unheated por-
tions of buildings.
• with pipe connections exposed to
freezing temperatures; for example,
sprinkler drops from wet-pipe sys-
tems into freezers or horizontal pip-
ing extensions to protect unheated
areas.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

• in systems that are seasonably
drained to avoid freezing; for exam-
ple, vacation areas.
The stainless-steel construction of
these sprinklers extends the life of a
sprinkler beyond that of traditional
copper alloy sprinklers exposed to
corrosive
corrosion-resistant
passed the standard corrosion tests
of the applicable approval agencies,
the testing is not representative of all
possible corrosive atmospheres.
Consequently, it is necessary that the
end user be consulted with respect to
the suitability of this alternate material
of construction for any given corrosive
environment. As a minimum, consider
the following criteria:
• ambient temperature
• concentration of chemicals
• humidity
• gas/chemical velocity
• corrosive nature of the chemical to
storage
which the sprinklers are exposed
Stainless Steel Pendent Dry-Type
Sprinklers. The pendent sprinklers
are provided with stainless steel es-
cutcheons that allow vertical ad-
justment
adjustment provides a measure of
flexibility in determining the length of
fixed piping to cut for sprinkler drops.
Stainless Steel Sidewall Dry-Type
Sprinklers. The horizontal sidewall
sprinklers are designed for installation
along a wall or side of a soffit and just
beneath a smooth ceiling. Sidewall
sprinklers are commonly used instead
of pendent sprinklers due to aesthet-
ics or building construction consider-
ations where piping along the ceiling
is not desirable.
