IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condi-
tion. Contact the installing contrac-
tor or product manufacturer 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.

General
Description
TYCO Series DS-1 Dry-Type Sprinklers,
5.6K Pendent, Upright, and Horizontal
Sidewall, Quick Response (3 mm bulb)
and Standard Coverage are decora-
tive glass bulb automatic sprinklers
designed for commercial use. Dry-type
sprinklers are typically used where:
• pendent sprinklers are required on
dry pipe systems that are exposed
to freezing temperatures (e.g.,
sprinkler drops from unheated
portions of buildings)
• sprinklers and/or a portion of the
connecting piping are exposed to
freezing temperatures; for example,
sprinkler drops from wet systems
into freezers, sprinkler sprigs
from wet systems into unheated
attics, or horizontal piping exten-
sions through a wall to protect an
unheated areas such as loading
docks, overhangs, and building
exteriors
• sprinklers are used on systems that
are seasonally drained to avoid
freezing (e.g., vacation areas)
NOTICE
The Series DS-1 Dry-Type Sprinklers
described herein must be installed
and maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
tection Association (NFPA), in addition
to the standards of any authorities
having jurisdiction. Failure to do so
may impair the performance of these
devices.

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 inch NPT Series
DS-1 Dry-Type Sprinklers in the 3/4 or
1 inch 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 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 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. Refer to the Exposure Length
section.
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
fittings:
• 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 Sprin-
klers 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 2-1/2-
inch reducing tee when locating the
Series DS-1 Sprinklers directly below
the branch line. Otherwise, use the
configuration shown in Figure 13 to
assure complete water drainage from
above the Series DS-1 Dry-Type Sprin-
klers 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 Pro-
tection Association for dry pipe sprin-
kler systems, branch, cross, and
feed-main piping connected to Dry
Sprinklers and subject to freezing tem-
peratures must be pitched for proper
drainage.

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.
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 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.
• A leak-tight 3/4 inch NPT sprinkler
joint should be obtained by applying
a minimum-to-maximum torque of
10 to 20 ft.-lbs. (13,4 to 26,8 Nm).
• A leak-tight 1 inch NPT sprinkler
joint should be obtained by applying
a minimum-to-maximum 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
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 (Ref. Figures 1 and 2)
• the W-Type 7 Sprinkler Wrench on
the Wrench Flat (Ref. Figure 16)
Apply the Wrench Recess of the
W-Type 7 Sprinkler Wrench to the
Wrench Flat.
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
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. 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 con-
necting an area subject to freezing and
an area containing a wet pipe sprinkler
system, the clearance space around
the sprinkler barrel of Dry-Type Sprin-
klers must be sealed. Due to tempera-
ture differences between two areas, the
potential for the formation of conden-
sation in the sprinkler and subsequent
ice build-up is increased. If this con-
densation is not controlled, ice build-up

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 sprin-
kler that has a cracked bulb or that has
lost liquid from its bulb. (Ref. Installa-
tion 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 Asso-
ciation (e.g., NFPA 25), in addition to
the standards of any other authorities
having jurisdiction. Contact the install-
ing 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.

DS-1 Dry-Type Sprinklers
When ordering TYCO Series DS-1
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 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.

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 fire situation.
A Vent Hole is provided in the Bulb
Seat (Ref. 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 (e.g., an improper installation
or an ice plug). Close the fire protec-
tion 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
