Operation
When the TYCO Series DS-1 Dry-Type
Sprinklers, 5.6K Pendent, Upright, and
Horizontal Sidewall, Quick Response
(3 mm bulb) and Standard Coverage
are in service, water is prevented from
entering the assembly by the Plug with
Sealing Assembly in the Inlet of the
Sprinkler. See Figures 1 and 2.
The glass bulb contains a fluid that
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter
the glass Bulb, and the Bulb Seat is
released.
The compressed Spring is then able
to expand and push the Water Tube as
well as the Guide Tube outward. This
action simultaneously pulls inward on
the Yoke, withdrawing the Plug with
Sealing Assembly from the Inlet and
allowing the sprinkler to activate and
flow water.
Design
Criteria
The TYCO Series DS-1 Dry-Type Sprin-
klers, 5.6K Pendent, Upright, and Hor-
izontal Sidewall, Quick Response
(3 mm bulb) and Standard Cover-
age are intended for use in fire sprin-
kler systems designed in accordance
with the standard installation rules
recognized by the applicable Listing
or Approval agency; for example,
UL Listing is based on NFPA 13
requirements.
Sprinkler Fittings
Install the 3/4 or 1 in. NPT Series
DS-1 Dry-Type Sprinklers in the 3/4
or 1 in. NPT outlet or run of the follow-
ing fittings:
•
malleable or ductile iron threaded
tee ttings that meet the dimen-
sional requirements of ANSI B16.3
(Class 150)
•
cast iron threaded tee ttings that
meet the dimensional requirements
of ANSI B16.4 (Class 125)
Do not install the DS-1 Sprinklers
into an elbow fittings. 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 Figure 13.
You can also install the Series DS-1
Dry-Type Sprinklers in the 3/4 or 1 in.
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 configuration shown in Figure 12
is only applicable for wet pipe systems
where the sprinkler fitting and water-
filled pipe above the sprinkler fitting are
not subject to freezing and where the
length of the Dry-Type Sprinkler has the
minimum exposure length depicted in
Figure 11. See the Exposure Length
section.
For wet pipe system installations of the
1 in. NPT Series DS-1 Dry-Type Sprin-
klers connected to CPVC piping, use
only the following TYCO CPVC fittings:

PROTECTION ASSOCIATION for dry
pipe sprinkler systems, branch, cross,
and feed-main piping connected to Dry
Sprinklers and subject to freezing tem-
peratures must be pitched for proper
drainage.
Exposure Length
When using Dry Sprinklers in wet pipe
sprinkler systems to protect areas
subject to freezing temperatures, use
Table C to determine a sprinkler’s
appropriate exposed barrel length to
prevent water from freezing in the con-
necting pipes due to conduction. The
exposed barrel length measurement
must be taken from the face of the
sprinkler fitting to the surface of the
structure or insulation that is exposed
to the heated area. See Figure 11 for
an example.
Clearance Space
In accordance with NFPA 13, when
connecting an area subject to freez-
ing and an area containing a wet pipe
sprinkler system, the clearance space
around the sprinkler barrel of Dry-Type
Sprinklers must be sealed. Due to
temperature differences between two
areas, the potential for the formation of
condensation in the sprinkler and sub-
sequent ice build-up is increased. If
this condensation is not controlled, ice
build-up can occur that might damage
the dry-type sprinkler and/or prevent
proper operation in a re situation.
Use of the Model DSB-2 Dry Sprin-
kler Boot, described in Technical Data
Sheet TFP591 and shown in Figures 14
and 15, can provide the recommended
seal.
Installation
The TYCO Series DS-1 Dry-Type Sprin-
klers, 5.6K Pendent, Upright, and Hori-
zontal Sidewall, Quick Response (3 mm
bulb) and Standard Coverage must
be installed in accordance with this
section.
General Instructions
The Series DS-1 Dry-Type Sprinklers
must only be installed in fittings that
meet the requirements of the Design
Criteria section. See the Design Crite-
ria section for other important require-
ments regarding piping design and
sealing of the clearance space around
the Sprinkler Casing.
Do not install any bulb-type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 in.
(1,6 mm) for the 135°F (57°C) rating to
1/8 in. (3,2 mm) for the 286°F (141°C)
rating.

•
A leak-tight 3/4 in. NPT sprinkler
joint should be obtained by applying
a minimum-to-maximum torque of
10 to 20 lb-ft (13,4 to 26,8 N·m).
• A leak-tight 1 in. NPT sprinkler joint
should be obtained by applying a
minimum-to-maximum torque of 20
to 30 lb-ft (26,8 to 40,2 N·m).
Higher levels of torque can distort the
sprinkler Inlet with consequent leakage
or impairment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in an Escutch-
eon Plate by under or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Step 1. Install pendent sprinklers only
in the pendent position, and install
upright sprinklers only in the upright
position. The deflector of a pendent or
upright sprinkler must be parallel to the
ceiling.
Install horizontal sidewall sprinklers in
the horizontal position with their cen-
terline of waterway perpendicular to
the back wall and parallel to the ceiling.
Ensure the word “TOP” on the Deflector
faces the ceiling.
Step 2. With a non-hardening pipe-
thread sealant such as TEFLON tape
applied to the Inlet threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 3. Wrench-tighten the sprinkler
using either:
•
a pipe wrench on the Inlet Band or
the Casing, see Figures 1 and 2
•
the W-Type 7 Sprinkler Wrench on
the Wrench Flat, see Figure 16
Apply the Wrench Recess of the
W-Type 7 Sprinkler Wrench to the
Wrench Flat.
Note: If sprinkler removal becomes neces-
sary, 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 followed. After removal, inspect the
sprinkler for damage.
Step 4. After installing the ceiling or
wall and applying a ceiling finish, slide
on the outer piece of the escutcheon
until it comes in contact with the ceiling
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 approximately 1/4
turn with respect to the outer piece,
to hold the Deep Escutcheon firmly
together.

•
Escutcheon Style and Finish, as
applicable
• Part Number (P/N) from Table D
The Upright Sprinkler without an
Escutcheon (TY3135) is available in
1 in. NPT only.
Part Numbers are for 3/4 in. and
1 in. NPT standard order sprin-
klers. Orders for all other sprinkler
assemblies must be accompanied
by a complete description. Refer to
the Price List for a complete listing
of Part Numbers.
Absence of the outer piece of an
escutcheon, which is used to cover a
clearance hole, can delay the time to
sprinkler operation in a fire situation.
A Vent Hole is provided in the Bulb
Seat (see Figures 1 and 2) to indicate
if the Dry-Type Sprinkler is remaining
dry. Evidence of leakage from the Vent
Hole indicates potential leakage 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
fire protection system control valve and
drain the system before removing the
sprinkler.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified 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.
Care must be exercised to avoid
damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged 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. See the Installation
Section.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION, such as NFPA 25, in
addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
