IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and in-
stallation of sprinkler systems and

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

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 freez-
ing temperatures (e.g., sprinkler drops
from unheated portions of buildings)
• sprinklers and/or a portion of the con-
necting 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
extensions 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 freez-
ing (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
Protection Association (NFPA), in ad-
dition to the standards of any authori-
ties 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 en-
tering 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 ex-
pands 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
Sealing Assembly from the Inlet and
allowing the sprinkler to activate and
ow water.

Criteria
The TYCO Series DS-1 Dry-Type
Sprinklers, 5.6K Pendent, Upright, and
Horizontal Sidewall, Quick Response (3
mm bulb) and Standard Coverage are
intended for use in re sprinkler sys-
tems 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 ttings:
• malleable or ductile iron threaded tee
ttings that meet the dimensional re-
quirements 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 sprin-
kler can contact the interior of the el -
bow, 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 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.
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

TABLE C
EXPOSED SPRINKLER BARRELS IN WET PIPE SYSTEMS
MINIMUM RECOMMENDED LENGTHS
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 Sprinklers
must be sealed. Due to temperature dif-
ferences between two areas, the poten-
tial 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 sprin-
kler 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 TYCO Series DS-1 Dry-Type
Sprinklers, 5.6K Pendent, Upright, and
Horizontal 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 ttings that
meet the requirements of the Design
Criteria section. Refer to the Design
Criteria section for other important re-
quirements 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
insufcient adjustment in an
Escutcheon Plate by under or over-
tightening the sprinkler. Re-adjust the
position of the sprinkler tting to suit.
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 tem-
peratures must be pitched for proper
drainage.
Exposure Length
When using Dry Sprinklers in wet pipe
sprinkler systems to protect areas sub -
ject 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 insula-
tion that is exposed to the heated area.
Refer to Figure 11 for an example.
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 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 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

TFP510
Page 8 of 10
Absence of the outer piece of an es-
cutcheon, 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 (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 re protec-
tion system control valve and drain the
system before removing the sprinkler.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro -
sion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modied 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 dam-
age 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. (Ref. Installation Section.)
The owner is responsible 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 Protection Association
(e.g., NFPA 25), in addition to the stan-
dards of any other authorities having
jurisdiction. Contact the installing con-
tractor or product manufacturer with
any questions.
Automatic sprinkler systems are recom-
mended to be inspected, tested, and
maintained by a qualied Inspection
Service in accordance with local re-
quirements and/or national codes.
Limited
Warranty

Step 1. Install pendent sprinklers only
in the pendent position, and install up-
right sprinklers only in the upright posi-
tion. The deector of a pendent or up-
right 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 ceil-
ing. Ensure the word “TOP” on the De-
ector faces the ceiling.
Step 2. With a non-hardening pipe-
thread sealant such as TEFLON tape
applied to the Inlet threads, hand-tight-
en the sprinkler into the sprinkler tting.
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.
Note: If sprinkler removal becomes
necessary, remove the sprinkler us-
ing the same wrenching method not-
ed above. Sprinkler removal is easier
when a non-hardening sealant was
used and torque guidelines were fol-
lowed. After removal, inspect the sprin-
kler for damage.
Step 4. After installing the ceiling or
wall and applying a ceiling nish, slide
on the outer piece of the escutcheon
until it comes in contact with the ceil-
ing 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 approxi-
mately 1/4 turn with respect to the out-
er piece, to hold the Deep Escutcheon
rmly together.
