Tyco Fire Product CENTRAL DS-1 User manual

General
Description
The Series DS-1, 5.6 K-factor, Quick
Response (3 mm Bulb) and Standard
Response (5 mm Bulb), Extended
Coverage Horizontal Sidewall, Dry
Type Sprinklers are decorative glass
bulb automatic sprinklers. They are in-
tended for use in applications where
the sprinklers and/or a portion of the
connecting piping may be exposed to
freezing temperatures (e.g., horizontal
piping extensions through a wall to
protect an unheated area of a build-
ing). The Series DS-1 Extended Cov-
erage Horizontal Sidewall Sprinklers
are designed for extended coverage
use in light hazard occupancies
(ECLH).
WARNINGS
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, in addition to the
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the integrity of these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
The Series DS-1 Dry Type Sprinklers
must only be installed in fittings that
meet the requirements of the Design
Criteria section.

Operation
WhentheSeriesDS-1isinservice,
water is prevented from entering the
assembly by the Plug & Belleville Seal-
ing Assembly (Ref. Figure 1) in the
Inlet of the Sprinkler. The glass Bulb
contains a fluid that expands when ex-
posed to heat. When the rated tem-
perature is reached, the fluid expands
sufficiently to shatter the glass Bulb,
and the Bulb Seat is released. The
compressed Spring is then able to ex-
pand and push the Water Tube as well
as the Guide Tube outward.This action
simultaneously pulls inward on the
Yoke, withdrawing the Plug & Belleville
Seal from the Inlet allowing the sprin-
kler to activate and flow water.

NOTE
Do not install the Series DS-1 into any
other type fitting without first consult-
ing the Technical Services Depart-
ment. Failure to use the appropriate
fitting may result in: failure of the sprin-
kler to properly operate due to forma-
tion of ice over the inlet Plug or binding
of the inlet Plug; or, insufficient en-
gagement of the inlet pipe threads with
consequent leakage.
Branch, cross, and feedmain piping
connected to Dry Sprinklers and sub-
ject to freezing temperatures must be
pitched for drainage in accordance
with the minimum requirements of the
National Fire Protection Association
for dry pipe sprinkler systems.
When Dry Sprinklers are to be used in
wet pipe sprinkler systems protecting
areas subject to freezing temperatures
(e.g., horizontal extensions into freez-
ers), consideration must be given to
the appropriate length of the sprinkler
that will prevent freezing of the water
in the connecting pipes due to conduc-
tion. When the temperature surround-
ing the wet pipe sprinkler system is
maintained at a minimum temperature
of 40°F/4°C, the following are the mini-
mum recommended lengths between
the face of the sprinkler fitting and the
outside surface of the protected area
(i.e., length exposed to minimum am-
bient of 40°F/4°C):
•12 inches (300 mm) when the tem-
perature within the protected area
is -20°F/-29°C
•18 inches (450 mm) when the tem-
perature within the protected area
is -40°F/-40°C
•24 inches (600 mm) when the tem-
perature within the protected area
is -60°F/-51°C
For protected area temperatures be-
tween those given above, the minimum
recommended length from the face of
the fitting to the outside of the pro-
tected area may be determined by in-
terpolating between the indicated val-
ues.
NOTE
When Dry Sprinklers penetrate a wall
into an area subject to freezing, the
clearance space around the Sprinkler
Casing must be completely sealed in
order to prevent the leakage of moist
air into the freezing area which might
result in the formation of condensate
around the Frame, Deflector, Bulb
Seat, or Bulb. Failure to prevent the
formation of condensate could result in
the build-up of ice around the releasing
components. This could result in an
inadvertent operation of the sprinkler
or impaired operation due to reduced
thermal sensitivity.

Installation
The Series DS-1 Dry Type Sprinklers
must be installed in accordance with
the following instructions:
NOTES
TheSeriesDS-1mustonlybeinstalled
in fittings that meet the requirements
of the Design Criteria section.
Refer to the Design Criteria section for
other important requirements regard-
ing 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 sprinkler
held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm).
A leak tight 1 inch NPT sprinkler joint
should be obtained with a torque of 20
to 30 ft.lbs. (26,8 to 40,2 Nm). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
Step 1. Horizontal sidewall sprinklers
are to be installed in the horizontal
position with their centerline of water-
way perpendicular to the back wall and
parallel to the ceiling. The word “TOP”
on the Deflector is to face towards the
ceiling.
Step 2. With pipe thread sealant ap-
plied to the inlet threads, hand tighten
the sprinkler into the sprinkler fitting.
Step 3. Wrench tighten the sprinkler by
wrenching on the Casing with a pipe
wrench whenever the casing is readily
accessible. Otherwise, use a W-Type 7
Sprinkler Wrench (Ref. Figure 3). The
wrench recess of the W-Type 7 is to be
applied to the sprinkler wrench flats
(Ref. Figure 3).
Step 4. After the wall has been in-
stalled/finished, slide on the outer
piece of the Escutcheon until it comes
in contact with the ceiling/wall.
Care and
Maintenance
The Series DS-1 Dry Type Sprinklers
must be maintained and serviced in
accordance with the following instruc-
tions:
NOTES
Absence of the outer piece of an es-
cutcheon, which is used to cover a
clearance hole, may delay the time to
sprinkler operation in a fire situation.
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 all personnel who may be
affected by this action must be notified.
A Vent Hole is provided in the Bulb
Seat (Ref. Figure 1) to indicate if the
Dry Sprinkler is remaining dry. Evi-
dence of leakage from the Vent Hole is
an indication that there may be
weepage past the Inlet seal and that
the sprinkler needs to be removed for
determining the cause of leakage (e.g.
an improper installation or an ice plug).
The fire protection system control
valve must be closed and the system
drained before removing the sprinkler.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
ture will exceed 100°F/38°C and they
must never be painted, plated, coated,
or otherwise altered after leaving the
factory. Modified sprinklers must be re-
placed. Sprinklers that have been ex-
posed to corrosive products of com-
bustion, but have not operated, should
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 - before, during, and after instal-
lation. Sprinklers damaged by drop-
ping, 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 fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative
to any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
