General
Description
TYCO Series DS-1 5.6K Pendent,
Upright, and Horizontal Sidewall, Stan-
dard Response (5 mm bulb), Standard
Coverage Dry-type Sprinklers are dec-
orative glass bulb automatic sprinklers
typically used where:
•
pendent sprinklers are required
on dry pipe systems that are
exposed to freezing temperatures;
for example, sprinkler drops from
unheated portions of buildings
• sprinklers and/or a portion of the
connecting piping may be exposed
to freezing temperatures (for
example, sprinkler drops from wet
systems into freezers, or horizontal
piping extensions through a wall to
protect unheated areas of a building
such as loading docks, overhangs,
and building exteriors)
•
sprinklers are used on systems that
are seasonably drained to avoid
freezing (for example, vacation
resort areas)

Operation
When TYCO Series DS-1 5.6K Pendent,
Upright, and Horizontal Sidewall, Stan-
dard Response, Standard Coverage
Dry-type Sprinklers are in service,
water is prevented from entering the
assembly by the Plug with Sealing
Assembly (see 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, allow-
ing the sprinkler to activate and flow
water.

Sprinkler Fittings
Install 1 in. NPT Series DS-1 Dry-type
Sprinklers in the 1 in. NPT outlet or run
of the following fittings:
• malleable or ductile iron threaded
tee fittings that meet the dimen-
sional requirements of ANSI B16.3
(Class 150 )
• cast iron threaded tee fittings that
meet the dimensional requirements
of ANSI B16.4 (Class 125)
Do not install Series DS-1 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 12.
You can also install Series DS-1 Dry-
type Sprinklers in the 1 in. NPT outlet
of a GRINNELL Figure 730 Mechanical
Tee and GRINNELL G-FIRE Figure 522;
however, the use of the Figure 730 Tee
and Figure 522 for this arrangement is
limited to wet pipe systems.
The configuration shown in Figure 13
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. See the Exposure Length
section.
For wet pipe system installations of
1 in. NPT Series DS-1 Dry-Type Sprin-
klers 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 in. reducing tee when locat-
ing Series DS-1 Dry-type Sprinklers
directly below the branchline; other-
wise, use the configuration shown in
Figure 12 to assure complete water
drainage from above 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 Series DS-1 Dry-type
Sprinklers into any other type fitting.

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 tem-
peratures 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 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. See Figure 11 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 freez-
ing 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 tem-
perature 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
TYCO Series DS-1 5.6K Pendent,
Upright, and Horizontal Sidewall, Stan-
dard Response, Standard Coverage
Dry-type Sprinklers must be installed
in accordance with this section.
General Instructions
Series DS-1 Dry-type Sprinklers must
only be installed in fittings that meet
the requirements of the Design Cri-
teria section. See the Design Criteria
section for other important require-
ments 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 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.
Obtain a leak-tight 1 in. NPT sprinkler
joint by applying a minimum-to-maxi-
mum torque of 20 to 30 lb-ft (26,8 to
40,2 N·m). Higher levels of torque may
distort the sprinkler Inlet with conse-
quent 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.
Notes:
• Install pendent sprinklers only in
the pendent position; install upright
sprinklers only in the upright posi-
tion. The deflector of a pendent or
upright sprinkler is to be parallel to
the ceiling.
• Install horizontal sidewall sprinklers
in the horizontal position with their
centerline of waterway perpendicu-
lar to the back wall and parallel to
the ceiling. Ensure the word “TOP”
on the Deflector faces the ceiling.
Step 1. With a non-hardening pipe-
thread sealant such as TEFLON applied
to the inlet threads, hand-tighten the
sprinkler into the sprinkler fitting.
Step 2. Wrench-tighten the sprinkler
using either:
• a pipe wrench on the Inlet Band or
the Casing, see Figure 1
• the W-Type 7 Sprinkler Wrench on
the Wrench Flat, see Figure 2
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.
Step 3. After installing the ceiling or
wall and applying a ceiling finish, slide
on the outer piece of the escutch-
eon until it comes in contact with the
ceiling/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.

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 (see 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 determine the cause of leakage;
for example, 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
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 sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. See the 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, such as 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 rec-
ommended to be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
