Operation
When TYCO Series DS-2 Dry-Type
Sprinklers are in service, water is
prevented from entering the assembly
by the Plug with Gasketed Spring
Plate Seal (Figure 1) in the Inlet of the
Sprinkler.
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, 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
Gasketed Spring Plate Seal from the
Inlet, allowing the sprinkler to activate
and ow water.

TABLE C
EXPOSED SPRINKLER BARRELS IN WET PIPE SYSTEMS
— MINIMUM RECOMMENDED LENGTHS —
The conguration shown in Figure 8 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 Dry-Type Sprinkler has the
minimum exposure length depicted in
Figure 10. Refer to the Exposure Length
section.
For wet pipe system installations of
1-inch NPT Series DS-2 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 Series
DS-2 Dry-Type Sprinklers directly
below the branch line. Otherwise, use
the conguration shown in Figure 9 to
assure complete water drainage from
above Series DS-2 Dry-Type Sprinklers
and the branch line. Failure to do so
may result in pipe freezing and water
damage.
NOTICE
Do not install Series DS-2 Dry-Type
Sprinkler into any other type fitting
without first consulting the Technical
Services Department. Failure to use the
appropriate fitting may result in one of
the following:
• Failure of the sprinkler to operate prop-
erly due to formation of ice over the
Inlet Plug or binding of the Inlet Plug.
• Insufficient engagement of the Inlet
pipe-threads with consequent leakage.
Drainage
In accordance with the minimum
requirements of the National Fire
Protection Association for dry pipe
sprinkler systems, branch, cross, and
feed-main piping connected to Dry
Sprinklers and subject to freezing
temperatures 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
connecting pipes due to conduction.
The exposed barrel length measure-
ment must be taken from the face of
the sprinkler tting to the surface of the
structure or insulation that is exposed
to the heated area. Refer to Figure 10
for an example.
Design
Criteria
TYCO Series DS-2 Dry-Type Sprinklers
are intended for use in re sprinkler
systems designed in accordance with
the standard coverage installation rules
recognized by the applicable Listing
agency; for example, UL Listing is
based on NFPA 13 requirements.
Sprinkler Fittings
Install 1-inch NPT Series DS-2 Dry-Type
Sprinklers in the 1-inch NPT outlet or
run of the following ttings:
• 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 Series DS-2 Dry-Type
Sprinklers into elbow ttings. The Inlet
of the sprinkler can contact the interior
of the elbow.
The unused outlet of the threaded tee is
plugged as shown in Figure 9.
You can also install Series DS-2
Dry-Type 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.

DRY-TYPE PENDENT SPRINKLER
For protected area temperatures
between those given above, the
minimum recommended length from
the face of the tting to the outside of
the protected area may be determined
by interpolating between the indicated
values.
Clearance Space
In accordance with Section 8.4.9.2
of the 2010 edition of NFPA 13, when
connecting an area subject to freezing
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
subsequent 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 Sprinkler
Boot, described in technical data sheet
TFP591 and shown in Figure 11, can
provide the recommended seal.
Installation
Series DS-2 Dry-Type Sprinklers must
be installed in accordance with the
following instructions.
NOTICE
Series DS-2 Dry-Type Sprinklers must
only be installed in fittings that meet
the requirements of the Design Criteria
section. Refer to the Design Criteria
section for other important require-
ments regarding piping design and
sealing of the clearance space around
the Sprinkler Casing. With reference
to Figure 7, do not grasp the sprinkler
by the deflector. Failure to follow this
instruction may impair performance of
the device.
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) rating to
1/8 inch (3,2 mm) for the 360°F (182°C)
rating.
Obtain a leak-tight 1-inch NPT sprinkler
joint by applying a minimum-to-
maximum torque of 20 to 30 ft. lbs.
(26,8 to 40,2 Nm). Higher levels of
torque may distort the sprinkler Inlet
with consequent leakage or impairment
of the sprinkler.
Do not attempt to compensate
for insufcient adjustment in an
Escutcheon Plate by under or over-
tightening the Sprinkler. Re-adjust the
position of the sprinkler tting to suit.
1. Install pendent sprinklers only in the
pendent position. The deector of a
pendent sprinkler must be parallel
to the ceiling.
2. With a non-hardening pipe-thread
sealant such as Teon*applied to
the Inlet threads, hand-tighten the
sprinkler into the sprinkler tting.
Do not grasp the sprinkler by the
deflector (Figure 7).
3. Wrench-tighten the sprinkler using
either:
• a pipe wrench on the Inlet Band or
the Casing (Figure 1).
• the W-Type 17 Sprinkler Wrench
on the Wrench Flat (Figure 2).
Apply the Wrench Recess of the
W-Type 17 Sprinkler Wrench to the
Wrench Flat.

TFP530
Page 6 of 8

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 guide-
lines were followed. After removal,
inspect the sprinkler for damage.
4. After installing the ceiling and
applying a ceiling nish, slide on the
outer piece of the Escutcheon until
it comes in contact with the ceiling.
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 rmly together.
Care and
Maintenance
TYCO Series DS-2 Dry-Type Sprinklers
must be maintained and serviced
in accordance with the following
instructions.
NOTICE
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, obtain permission to
shut down the affected fire protection
systems from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the outer piece of an
escutcheon, which is used to cover a
clearance hole, may delay the time to
sprinkler operation in a re situation.
A Vent Hole is provided in the Bulb Seat
(Figure 1) to indicate if the Dry 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 re protection system control
valve and drain the system before
removing the sprinkler.
Exercise care to avoid damage before,
during, and after installation. Never
paint, plate, coat, or otherwise alter
automatic sprinklers after they leave
the factory.
Never repaint factory-painted Cover
Plates. When necessary, replace
cover plates with factory-painted
units. Non-factory applied paint can
adversely delay or prevent sprinkler
operation in the event of a re.
Replace sprinklers that:
•were damaged by dropping, striking,
wrench twisting, wrench slippage, or
the like.
•were modied or over-heated.
• have cracked bulbs or have lost liquid
from the bulbs. Refer to the Installation
Section in this data sheet.
•are leaking or exhibiting visible signs
of corrosion.
Responsibility lies with owners for the
inspection, testing, and maintenance of
their re protection system and devices
in compliance with this document, as
well as with the applicable standards of
the National Fire Protection Association
(for example, NFPA 25), in addition to
the standards of any other Authorities
Having Jurisdiction. The installing
contractor or sprinkler manufacturer
should be contacted relative to any
questions.
Automatic sprinkler systems are recom-
mended to be inspected, tested, and
maintained by a qualied Inspection
Service in accordance with local
requirements and/or national codes.
