General
Description

TYCO Series DS-3 Dry-Type Sprinklers,
11�2K Horizontal Sidewall, Standard
Response, Extended Coverage, Ordi­nary Hazard (ECOH) are decorative
glass bulb automatic sprinklers� They
are intended for use in applications
where the sprinklers and/or a portion of
the connecting piping may be exposed
to freezing temperatures; for example,
horizontal piping extensions through a
wall to protect an unheated area of a
building�

Series DS-3 Extended Coverage
Ordinary Hazard Horizontal Sidewall,
Dry-Type Sprinklers are designed for
extended coverage use in ordinary
hazard occupancies ( ECOH) per NFPA
13�

Series DS-3 Dry-Type Sprinklers
provide protection of coverage areas
up to 16 ft x 20 ft (320 ft2) as compared
to standard coverage horizontal side­wall sprinklers having a maximum cov­erage area of 10 ft x 10 ft (100 ft2) for
ordinary hazard occupancies�

NOTICE

Series DS-3 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 other
authorities having jurisdiction. Failure

IMPORTANT

Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.

Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal­lation of sprinkler systems and com­ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo­nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

to do so may impair the performance
of these devices.

The owner is responsible for main­taining their fire protection system
and devices in proper operating con­dition. Contact the installing contrac­tor or product manufacturer with any
questions.

Series DS-3 Dry-Type Sprinklers must
only be installed in fittings that meet

Operation

When TYCO Series DS-3 Dry-Type
Sprinklers, 11�2K Horizontal Sidewall,
Standard Response, Extended Cov­erage, Ordinary Hazard (ECOH) are in
service, water is prevented from enter­ing the assembly by the Plug with
Sealing Assembly (Ref� Figure 1) in the
Inlet of the sprinkler�

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 allow­ing the sprinkler to activate and flow
wa te r�

The configuration shown in Figure 7 is
only applicable for wet pipe systems
where the sprinkler fitting and water­filled 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 10� Refer to the Exposure Length
section�

For wet pipe system installations of 1
inch NPT Series DS-3 Dry-Type Sprin­klers connected to CPVC piping, use
only the following TYCO CPVC fittings:

•

1 in. x 1 in. NPT Female Adapter
(P/N 80145)

•

1 in. x 1 in. x 1 in. 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-3 Dry-Type Sprinklers directly
below the branch line� Otherwise, use
the configuration shown in Figure 6 to
assure complete water drainage from
above Series DS-3 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-3 Dry-Type
Sprinklers 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 D 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 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� Refer to Figure 7 for
an example�

For protected area temperatures
between those given above, the
minimum recommended length from
the face of the fitting to the outside of
the protected area may be determined
by interpolating between the indicated
values�

Clearance Space

In accordance with 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 9,
can provide the recommended seal.

Installation

TYCO Series DS-3 Dry-Type Sprinklers,
11�2K Horizontal Sidewall, Standard
Response, Extended Coverage, Ordi­nary Hazard (ECOH) must be installed
in accordance with this section�

General Instructions

Series DS-3 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 require­ments regarding piping design and
sealing of the clearance space around
the Sprinkler Casing� With reference to
Figure 10, 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 in�
(1,6 mm) for the 135°F (57°C) rating to
1/8 in� (3,2 mm) for the 360°F (182°C)
rating�

A leak-tight 1 inch 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 may distort the sprin­kler Inlet with consequent leakage or
impairment of the sprinkler�

Do not attempt to compensate for
insufficient adjustment in an escutch­eon plate by under or over-tightening
the Sprinkler� Re-adjust the position of
the sprinkler fitting to suit�

Step 1. Install horizontal sidewall sprin­klers with the center line of waterway
parallel to the ceiling and perpendicu­lar to the back wall surface� The word
“TOP” on the deflector must face
upwards toward the ceiling�

Step 2. With a non-hardening pipe­thread sealant such as TEFLON applied
to the Inlet threads, hand-tighten the
sprinkler into the sprinkler fitting� Do
not grasp the sprinkler by the deflector
(Ref� Figure 10)�

Step 3. Wrench-tighten the sprinkler
using either:

•

a pipe wrench on the Inlet Band or
the Casing (Ref. Figure 1)

•

the W-Type 8 Sprinkler Wrench on
the Wrench Flat (Ref. Figure 11)

Apply the Wrench Recess of the
W-Type 8 Sprinkler Wrench to the
Wrench Flat�

FIGURE 10

DO NOT GRASP

DEFLECTOR

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�

Step 4. After applying a wall finish,
slide on the outer piece of the escutch­eon until it comes in contact with the
mounting surface�

For Deep Escutcheons, slide the outer
skirt over the inner cup to make firm
contact with the mounting surface�

Care and
Maintenance

TYCO Series DS-3 Dry-Type Sprinklers,
11�2K Horizontal Sidewall, Standard
Response, Extended Coverage, Ordi­nary Hazard (ECOH) must be main­tained and serviced in accordance with
this section�

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 fire 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 deter-

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 other­wise 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� Sprin­klers 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� (Refer to 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 (e�g�, 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 rec­ommended to be inspected, tested,
