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 a sprin-
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.
NOTICE
The Series DS-1 Stainless Steel Dry-
Type Sprinklers described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the National Fire Protection
Association (NFPA), 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 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.
• 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
copper alloy sprinklers exposed to
corrosive atmospheres. Although
corrosion-resistant 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 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 exibility in determining
the length of xed 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 soft 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.
General
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 rst 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 congurations to suit coverage
type and thermal sensitivity. Refer to
the Sprinkler Identication 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)

Operation
When TYCO Series DS-1 Stainless
Steel Dry-Type Sprinklers, 5.6K Pen-
dent, Horizontal Sidewall (HSW), and
Extended Coverage HSW, Standard
(5 mm bulb) and Quick (3 mm bulb)
Response are in service, water is pre-
vented from entering the assembly by
the Plug with Sealing Assembly in the
Inlet of the sprinkler. Refer to Figures 1
through 3.
The glass bulb contains a uid that
expands when exposed to heat. When
the rated temperature is reached, the
uid expands sufciently to shatter
the glass bulb then release the Bulb
Seat.
The compressed Spring is then able
to expand and push the Water Tube as
well as the Guide Tube outward. This
outward action simultaneously pulls
inward on the Yoke, withdrawing the
Plug with Sealing Assembly from the
Inlet and allowing the sprinkler to acti-
vate and ow water effectively.

Physical Characteristics
With the exceptions of the bulb, the
Insert, the Deector, and the Seal-
ing Assembly, all components of the
Series DS-1 Stainless Steel Dry-Type
Sprinkler are constructed with Type
316 Stainless Steel.
• The bulb is glass.
• The Insert is 300 Series Stainless
Steel.
• The Deector is Type 316L Stainless
Steel.
The Sealing Assembly consists of a
Disc Spring that is sealed on both its
inside and outside faces with a TEF-
LON gasket. The Disc Spring is 1/2
Hard Beryllium Nickel.
Refer to Figures 1 through 3 for com-
ponent assemblies.
• cast bronze threaded tee ttings
that meet the dimensional require-
ments of ANSI B16.15 (Class 125)
• stainless steel threaded tee ttings
that meet the dimensional require-
ments of MSS SP-114.
Do not install the Series DS-1 Stain-
less Steel Dry-Type Sprinklers into
elbow ttings. The inlet of the sprinkler
can contact the interior of the elbow,
potentially damaging the Inlet seal.
The unused outlet of the threaded tee is
plugged as shown in Figures 4 and 5.
You can also install the Series DS-1
Sprinklers in the 1 Inch NPT outlet of
a GRINNELL Figure 730 Mechanical
Tee. However, the use of the Figure
730 Tee for this arrangement is limited
to wet-pipe systems.
The conguration shown in Figure 4 is
only applicable for wet-pipe systems
where the sprinkler tting and water-
lled pipe above the sprinkler tting
are not subject to freezing and where
the length of the Stainless Steel Dry-
Type Sprinkler has the minimum
exposure length depicted in Figure 6.
Refer to the Exposure Length section.
For wet-pipe system installations of
the 1 Inch NPT Series DS-1 Stainless
Steel Dry-Type Sprinklers connected
to CPVC piping, use only the following
TYCO CPVC ttings:
• 1” x 1” NPT Female Adapter
(P/N 80145)
• 1” x 1” x 1” NPT Sprinkler Head
Adapter Tee (P/N 80249)
For dry-pipe system installations, use
only the side outlet of maximum 2-1/2
inch reducing tee when locating the
Series DS-1 Stainless Steel Dry-Type
Sprinklers directly below the branch
line. Otherwise, use the conguration
shown in Figure 5 to assure complete
water drainage from above the Series
DS-1 Stainless Steel Dry-Type Sprin-
klers and the branchline. Failure to
do so may result in pipe freezing and
water damage.
NOTICE
Do not install the Series DS-1
Stainless Steel Dry-Type Sprinklers
into any other type fitting without first
consulting the Technical Services
Department. Failure to use the
appropriate fitting can result in one of
the following:
• failure of the sprinkler to operate
properly due to formation of ice
over the Inlet Plug or binding of the
Inlet Plug
• insufficient engagement of the In-
let pipe threads with consequent
leakage

Drainage
In accordance with the minimum
requirements of the National Fire
Protection Association for dry-pipe
sprinkler systems, pitch branch, cross,
and feed main piping connected to
Stainless Steel Dry-Type Sprinklers
and subject to freezing temperatures
to allow proper drainage.
Exposure Length
When using Stainless Steel Dry-Type
Sprinklers in wet-pipe sprinkler sys-
tems protecting areas subject to
freezing temperatures, use Table C
to determine a sprinkler’s appropriate
exposed barrel length to prevent water
from freezing in the connecting pipes
due to conduction. The exposed bar-
rel length measurement must be taken
from the face of the sprinkler tting to
the surface of the structure or insu-
lation that is exposed to the heated
area. Refer to Figure 6 for an example.
Clearance Space
Section 8.4.9.2 of 2010 edition of
NFPA 13 requires a sealed clearance
space around the sprinkler barrel of
dry sprinklers that are connected to
wet-pipe sprinkler systems protect-
ing insulated freezer structures. The
use of the Model DSB-2 Dry Sprin-
kler Boot, described in technical
data sheet TFP591 and illustrated in
Figures 7 and 8, meets this NFPA 13
requirement.

Installation
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 must be installed in accor-
dance with this section.
NOTICE
The Series DS-1 must only be installed
in fittings that meet the requirements
of the Design Criteria section. For
other important requirements regard-
ing piping design and sealing of the
clearance space around the Sprinkler
Casing, refer to the Design Criteria
section.
Do not install any bulb type sprinkler if
the bulb is cracked or there is a loss of
liquid from the bulb. With the sprinkler
held horizontally, a small air bubble
should be present. The diameter of
the air bubble is approximately 1/16
inch (1,6 mm) for the 135°F (57°C) rat-
ing to 1/8 inch (3,2 mm) for the 286°F
(141°C) rating.
A leak-tight 1 inch NPT sprinkler joint
should be obtained by applying a min-
imum-to-maximum torque of 20 to 30
ft.-lbs. (26,8 to 40,2 Nm). Higher levels
of torque can distort the sprinkler Inlet
with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to compensate for in-
sufcient adjustment in an Escutch-
eon Plate by under- or over-tightening
the Sprinkler. Re-adjust the position of
the sprinkler tting to suit.
Step 1. Install pendent sprinklers
only in the pendent position with the
deector parallel to the ceiling. Install
horizontal sidewall sprinklers in the
horizontal position with their center-
line of waterway perpendicular to the
back wall and parallel to the ceiling.
Ensure the word “TOP” on the Deec-
tor faces the ceiling.
Step 2. With a non-hardening pipe
thread sealant such as TEFLON ap-
plied to the Inlet threads, hand-tighten
the sprinkler into the sprinkler tting.
Step 3. Wrench-tighten the sprinkler
using a pipe wrench on the Inlet Band
or Casing (refer to Figures 1 to 3) or
using the W-Type 7 Sprinkler Wrench
on the Wrench Flat (refer to Figure 9).
Note: If sprinkler removal becomes
necessary, remove the sprinkler using
the same wrenching method noted
above. Sprinkler removal is easier
when a non-hardening sealant was
used and torque guidelines were fol-
lowed. After removal, inspect the
sprinkler for damage.
Step 4. After installing the ceiling or
wall and applying a ceiling nish, slide
on the outer piece of the Escutcheon
until it comes in contact with the ceil-
ing or wall. Do not lift the ceiling panel
out of its normal position.
When using the Deep Escutcheon,
hold the outer piece in contact with
the mounting surface (ceiling or wall).
Then rotate the inner piece approxi-
mately 1/4 turn, with respect to the
outer piece, to hold the Deep Escutch-
eon rmly together.

Care must be exercised to avoid dam-
age to the sprinklers - before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb. (Refer to In-
stallation Section.)
The owner is responsible for the in-
spection, testing, and maintenance of

tion Service in accordance with local
requirements and/or national codes.
A Vent Hole is provided in the Bulb
Seat to indicate if the Dry Sprinkler
is remaining dry. (Refer to Figures 1
through 3.) Evidence of leakage from
the Vent Hole indicates potential leak-
age past the Inlet seal and the need
to remove the sprinkler to determine
the cause of leakage; for example, an
improper installation or an ice plug.
Close the re protection system con-
trol valve and drain the system before
removing the sprinkler.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro-
sion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modied sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
