Series DS-1 Dry-Type Sprinklers
Quick Response, Standard Coverage

5.6 K-factor, 3/4 and 1-Inch NPT

General
Description

The TYCO Series DS-1, 5.6 K-factor,
3/4 and 1-Inch NPT, Quick Response,
Standard Coverage, Dry-Type Sprink­lers are decorative, 3-mm glass bulb
automatic sprinklers de signed for com­mercial use. Dry-Type Sprinklers are
typically used where:

•

pendent sprinklers are re quired on
dry pipe systems that are exposed to
freezing tempera tures; for example,
sprinkler drops from un heated por­tions of buildings.

•

sprinklers and/or a portion of the con­necting piping are exposed to freezing
temperatures; for example, sprinkler
drops from wet sys tems into freezers,
sprinkler sprigs from wet systems into
unheated attics, or horizontal piping
extensions through a wall to protect an
unheated areas such as loading docks,
overhangs, and building exteriors.

•

sprinklers are used on sys tems that are
seasonally drained to avoid freezing;
for example, vacation areas.

jurisdiction. Failure to do so may impair
the performance of these de vices.

Owners are responsible for maintain ing
their fire protection system and de vices
in proper operating condition. The in­stalling contractor or sprinkler manu­facturer should be contacted with any
questions.

The Series DS-1 Dry-Type Sprinklers
must only be installed in fittings that
meet the requirements of the Design
Criteria section.

Operation

When the TYCO Series DS-1 Dry-Type
Sprinkler is 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 uid that ex­pands when ex posed to heat. When the
rated tem perature 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 ex pand 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 sprin kler to activate and
ow water.

Design
Criteria

The TYCO Series DS-1 Sprinklers are
intended for use in re sprinkler 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-inch NPT Series
DS-1 Dry-Type Sprinklers in the 3/4 or
1-inch NPT outlet or run of the follow­ing ttings:

•

malleable or ductile iron threaded tee
ttings that meet the dimensional 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 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 12 and 13.

You can also install the Series DS-1
Dry-Type Sprinklers in the 3/4 or 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 12
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 11. Refer to the Exposure Length
section.

TFP510

Page 6 of 10

For wet pipe system installations of
the 1-inch NPT Series DS-1 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 wet pipe system installations of
the the 3/4-inch NPT Series DS-1
Sprinklers connected to CPVC pip­ing, use in the 3/4" x 3/4" NPT Female
Adapter (P/N 80142).

For dry pipe system installations, use
only the side outlet of maximum 2-1/2­inch reducing tee when locating the
Series DS-1 Sprinklers directly below
the branch line. Otherwise, use the con­guration shown in Figure 13 to assure
complete water drainage from above
the Series DS-1 Dry-Type Sprinklers
and the branch line. Failure to do so
may result in pipe freezing and water
damage.

NOTICE

Do not install the Series DS-1 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 prop­erly 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 bar-

rel length measurement 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 11 for an example.

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 Figures 14 and
15, can provide the recommended seal.

Installation

The T YCO Series DS-1 Dry-Type
Sprinklers must be installed in accor­dance with the following instructions.

NOTICE

The Series DS-1 Dry-Type Sprinkler
must only be installed in fittings that
meet the requirements of the Design
Criteria section. Refer to the Design
Criteria section for other important re­quirements regard ing 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 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 286°F (141°C)
rating.

•

Obtain a leak-tight 3/4-inch NPT sprin­kler joint by applying a minimum-to­maximum torque of 10 to 20 ft. lbs.
(13,4 to 26,8 Nm).

• Obtain a leak-tight 1 inch NPT sprin­kler joint by applying a minimum-to­maximum 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 impairment of the sprinkler.

Do not attempt to compensate for
insufcient adjustment in an
Escutcheon Plate by under or over­tightening the Sprinkler. Re-adjust the
position of the sprinkler tting to suit.

1.

Install pendent sprinklers only in the
pendent position, and install upright
sprinklers only in the upright posi­tion. The deector of a pendent or
upright sprin kler must be parallel to
the ceiling.

Install horizontal sidewall sprin­klers in the horizontal position with
their centerline of waterway perpen­dicular to the back wall and paral­lel to the ceiling. Ensure the word
“TOP” on the De ector faces the
ceiling.

2.

With a non-hardening pipe-thread
sealant such as Teon1 tape applied
to the Inlet threads, hand-tighten the
sprinkler into the sprinkler tting.

3.

Wrench-tighten the sprinkler using
either:

•

a pipe wrench on the Inlet Band or
the Casing (Figures 1 and 2)

•

the W-Type 7 Sprinkler Wrench on
the Wrench Flat (Figure 16).

1 Registered trademark of DuPont

Apply the Wrench Recess of the
W-Type 7 Sprinkler Wrench to the
Wrench Flat.

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 followed. After removal,
inspect the sprinkler for damage.

4.

After installing the ceiling or wall and
applying a celing nish, 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 rmly together.

Care and
Maintenance

The T YCO Series DS-1 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, can delay the time to
sprinkler operation in a re situation.

A Vent Hole is provided in the Bulb Seat
(Figures 1 and 2) to indicate if the Dry­Type 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 dam age before,
during, and after instal lation. 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
in spection, 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 Protec tion 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.
