Series DS-ECC Dry Type Sprinklers
5.6K Pendent Concealed
Quick Response, Extended Coverage
General
Description
TYCO Series DS-ECC Dry Type Sprin-
klers, 5.6K Pendent Concealed, Quick
Response (3 mm Bulb), Extended Cov-
erage (TY3539), are decorative bulb-
type sprinklers featuring a flat cover
plate designed to conceal the sprinkler.
This type of sprinkler is typically used
to provide a sprinkler drop from an
unheated attic into an area where aes-
thetics is a concern, such as nursing
homes, restaurants, and schools.
They are intended for use in auto-
matic sprinkler systems designed in
accordance with standard installation
rules, for example, NFPA 13. The fast
response thermal sensitivity rating of
Series DS-ECC Dry Type Sprinklers
(TY3539) provides for a quick response
extended coverage (QREC) rating up to
an 18 ft x 18 ft coverage area.
Each unit includes a Cover Plate
Assembly that conceals the sprin-
kler operating components above
the ceiling. The separable two-piece
design of the Cover Plate and Support
Cup Assemblies allows installation of
the sprinklers and pressure testing
of the fire protection system prior to
installation of a suspended ceiling or
application of the finish coating to a
fixed ceiling. They also permit removal
of suspended ceiling panels for access
to building service equipment without
having to first shut down the fire pro-
tection system and remove sprinklers.
Also, the separable two-piece design
of the Sprinkler provides for 1/2 in.
(12,7 mm) of vertical adjustment.
Each Series DS-ECC Dry Type Sprin-
kler is shipped with a Disposable Pro-
tective Cap. The Protective Cap is
temporarily removed for installation,
and then it can be replaced to help
protect the sprinkler while the ceiling
is being installed or finished. The tip of
the Protective Cap can also be used to
mark the center of the ceiling hole into
plaster board and ceiling tiles by gently
pushing the ceiling product against the
Protective Cap. When the ceiling instal-
lation is complete, the Protective Cap is
removed and the Cover Plate Assembly
installed.
NOTICE

Operation
When TYCO Series DS-ECC Dry Type
Sprinklers, 5.6K Pendent Concealed,
Quick Response, Extended Coverage
(TY3539) are in service, water is pre-
vented from entering the assembly by
the Plug and Gasketed Spring Plate
Seal (see Figure 1) in the Inlet of the
Sprinkler.
When exposed to heat from a fire, the
Cover Plate, which is normally soldered
to the Retainer at three points, falls
away to expose the Sprinkler Assem-
bly. At this point the Deflector sup-
ported by the Guide Pins drops down
to its operational position.
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 and Gasketed Spring Plate
Seal from the Inlet allowing the sprin-
kler to activate and flow water.

Design
Criteria
TYCO Series DS-ECC Dry Type
Sprinklers, 5.6K Pendent Concealed,
Quick Response, Extended Coverage
(TY3539) are UL and C-UL Listed for
use in light hazard occupancies, using
the design criteria in Table A, in addi-
tion to the requirements specified in the
current NFPA 13 for extended coverage
pendent sprinklers.
Series DS-ECC Dry-Type Sprinklers are
only listed when installed with Series
RFII Concealed Cover Plates having
a factory applied painted or metallic
finish.
NOTICE
Series DS-ECC Sprinklers must not
be used in applications where the air
pressure above the ceiling is greater
than that below. Down drafts through
the Support Cup could delay sprinkler
operation in a fire situation.
Sprinkler Fittings
Install 1 in. NPT Series DS-ECC Dry-
Type Sprinklers are to be installed in
the 1 in. NPT outlet or run of the fol-
lowing 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-ECC 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 Figures 6.
You can also install Series DS-ECC
Dry-Type Sprinklers in the 1 in. 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 5 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 7. See the Exposure Length
section.
For wet pipe system installations of
1 in. NPT Series DS-ECC 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 in. reducing tee when locating
Series DS-ECC Dry-Type Sprinklers
directly below the branch line. Oth-
erwise, use the configuration shown
in Figure 4 to assure complete water
drainage from above Series DS-ECC
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-ECC 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 B 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 5 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.
Do not attempt to add additional insula-
tion around the barrel in the heated area
as a method to minimize condensation.
This will reduce the calculated “Expo-
sure Length”.
Clearance Space
In accordance with NFPA 13, where dry
sprinklers are connected to wet pipe
sprinkler systems protecting insulated
freezer structures, 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 sub-
sequent 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 6, can
provide the recommended seal.
NOTICE
For applications where a bore greater
than 1 3/4 in. in diameter has been cut
through the entire height of an insu-
lated freezer ceiling creating a cavity
above the sprinkler support cup (see
Figure 8), the cavity must not be filled.
Installation
TYCO Series DS-ECC Dry Type
Sprinklers, 5.6K Pendent Concealed,
Quick Response, Extended Coverage
(TY3539) must be installed in accor-
dance with this section.
General Instructions
Series DS-ECC Dry-Type Sprinklers
must only be installed in fittings that
meet the requirements of the Design
Criteria section. See the Design Crite-
ria 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).
A leak-tight 1 in. NPT sprinkler joint

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 the Sprinkler
Assembly by under or over-tightening
the Sprinkler/Support Cup Assembly.
Re-adjust the position of the sprinkler
fitting to suit.
Step 1. Install pendent sprinklers only
in the pendent position and with the
centerline of the sprinkler perpendicu-
lar to the mounting surface.
Step 2. With a non-hardening pipe-
thread sealant such as TEFLON 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, see Figure 1.
•
the RFII Sprinkler Wrench (see
Figure 3) on the Wrench Flat.
Note: If sprinkler removal becomes neces-
sary, 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.
When using the RFII Sprinkler Wrench,
temporarily remove the Protective Cap.
Replace the Protective Cap (see Figure
4) by pushing it upwards until it bottoms
out against the Support Cup. The Pro-
tective Cap helps prevent damage to
the Deflector and Arms during ceiling
installation and/or during application of
the finish coating of the ceiling. It may
also be used to locate the center of the
clearance hole by gently pushing the
ceiling material up against the center
point of the Protective Cap.
NOTICE
As long as the Protective Cap remains
in place, the system is considered to be
“Out of Service”.
Step 4. After the ceiling has been
completed with the 2 1/2 in. (63,5 mm)
diameter hole and in preparation for
installing the Cover Plate Assembly,
remove and discard the Protective
Cap. Verify that the Deflector moves
up and down freely. If the Sprinkler has
been damaged and the Deflector does
not move up and down freely, replace
the entire Sprinkler assembly. Do not
attempt to modify or repair a damaged
sprinkler.
Step 5. Screw on the Cover Plate/
Retainer Assembly until the Retainer
(see Figure 2) contacts the ceiling. Do
not continue to screw on the Cover
Plate/Retainer Assembly so that it
lifts a ceiling panel out of its normal
position. If the Cover Plate/Retainer
Assembly cannot be engaged with
the Support Cup or the Cover Plate/
Retainer Assembly cannot be engaged
sufficiently to contact the ceiling, repo-
sition the Sprinkler Fitting.
Care and
Maintenance
TYCO Series DS-ECC Dry Type
Sprinklers, 5.6K Pendent Concealed,
Quick Response, Extended Coverage
(TY3539) must be maintained and ser-
viced 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, permission to shut down the
affected fire protection systems must
be obtained from the proper authori-
ties 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-
