Description
TYCO Series DS-1 Stainless Steel
Dry-Type Sprinklers, 5.6K Pendent,
Horizontal Sidewall (HSW), and Ex-
tended Coverage HSW, Standard (5
mm bulb) and Quick (3 mm bulb) Re-
sponse 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-resistant automatic
sprinklers can be used in wet-pipe,
dry-pipe, or preaction systems.
These pendent and horizontal side-
wall sprinklers are available in a vari-
ety of configurations to suit coverage
type and thermal sensitivity. Refer to
the Sprinkler Identification Numbers
(SINs) section for details.
Series DS-1 Stainless Steel Dry-Type
Sprinklers are typically used:
• where corrosive atmospheres exist
(e.g., salt-water areas, parking ga-
rages, chemical storage areas,
mechanical rooms, industrial manu-
facturing sites, and software chip
washing facilities)
• on dry-pipe systems exposed to
freezing temperatures (e.g., sprin-
kler drops from unheated portions
of buildings)
• with pipe connections exposed to
freezing temperatures (e.g., sprin-
kler drops from wet-pipe systems
into freezers or horizontal piping ex-
tensions 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 (e.g., va-
cation areas)
The stainless steel construction of
these sprinklers extends the life of a
sprinkler beyond that of traditional

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
which the sprinklers are exposed
Stainless Steel Pendent
Dry-Type Sprinklers
The pendent sprinklers are provided
with stainless steel escutcheons that
allow vertical adjustment during in-
stallation. This 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 pen-
dent sprinklers due to aesthetics or
building construction considerations
where piping along the ceiling is not
desirable.

NOTICE
The Series DS-1 Stainless Steel Dry-
Type Sprinklers described
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the National Fire
Association (NFPA), in addition to
the standards of any
having jurisdiction. 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 condi-
tion. Contact the installing contrac-
tor or product manufacturer with any
questions.
The Series DS-1 Stainless Steel Dry-
Type Sprinklers must only be installed
in fittings that meet the requirements
of the Design Criteria section.
