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
the requirements of the Design Criteria
section. Installation of Series DS-3 Dry­Type Sprinklers in a recessed installa­tion will void all sprinkler warranties, as
well as void the sprinkler’s laboratory
Approvals.

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�

Criteria

The TYCO Series DS-3 Dry-Type Sprin­klers, 11�2K Horizontal Sidewall, Stan­dard Response, Extended Coverage,
Ordinary Hazard (ECOH) are for use in
ordinary hazard occupancies with non­combustible unobstructed construction
and with a ceiling slope not exceed­ing 2 inches per foot (9�2° ), using the
design criteria provided in Table C, as
well as any additional requirements
specified in NFPA 13 for Extended Cov­erage Sidewall Spray Sprinklers�

A 36 in� (914 mm) clearance must be
maintained between the top of the
sprinkler deflector and any miscella­neous storage�

Series DS-3 Dry-Type Sprinklers may
be installed on sloped ceilings in
loading docks with a maximum roof
slope of 4 inches per foot (18�4°) as

run of the following fittings:

•

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 Series DS-3 Dry-Type
Sprinklers into elbow fittings� 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 6�

Series DS-3 Dry-Type Sprinklers can
also be installed 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�

shown in Figure 8 and using the design
criteria provided in Table C�

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�
