Tyco Fire Product CENTRAL S170 User manual

General
Description
The Central Model S170, 5.6 K-Fac-
tor (1/2 inch orifice), Standard or
Quick Response, Standard Cover-
age, Dry Pendent Sprinklers are
decorative glass bulb automatic
sprinklers designed for use
•where pendent sprinklers are re-
quired on dry pipe systems that are
exposed to freezing temperatures
(e.g. sprinkler drops from unheated
portions of buildings), or
•where sprinklers and/or a portion of
the connecting piping may be ex-
posed to freezing temperatures
(e.g. sprinkler drops from wet sys-
tems into freezers), or
•where pendent sprinklers are used
on systems that are seasonably
drained to avoid freezing (e.g. vaca-
tion resort areas).
The Model S170 Dry Pendent Sprin-
klers are available in standard re-
sponse (5 mm bulb) or quick re-
sponse (3 mm bulb) and in a wide
range of operating temperatures and
order lengths. The Model S170
Sprinklers are intended for use in
fire sprinkler systems designed in ac-
cordance with the standard installa-
tion rules recognized by the applica-
ble Listing or Approval agency (e.g.,
UL Listing is based on NFPA 13 re-
quirements). They produce a hemi-
spherical water discharge pattern be-
low the deflector.
The Recessed, Standard, and Deep
Ceiling Escutcheons for the Model
S170 are separable two-piece de-
signs which allow installation of the
sprinklers and pressure testing of
the fire protection system prior to in-
stallation of a suspended ceiling.
They also permit removal of sus-
pended ceiling panels without having
to first shut down the fire protection
system and remove the sprinklers.
Operation: When the Model S170 is
in service, water is prevented from
entering the assembly by the Plug &
O-ring(Ref.Figure2)intheInletof
the Sprinkler. The glass Bulb con-
tains a fluid which 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 re-
leased. The compressed Spring is
then able to expand and push the
WaterTubeaswellastheGuide
Tube outward. This action simultane-
ously pulls inward on the Yoke, with-
drawing the Plug & O-ring from the
Inlet, which then allows the sprinkler
to activate and flow water.
WARNINGS
The Model S170 Dry Pendent Sprin-
klers described herein must be in-
stalled and maintained in compli-
ance with this document, as well as
with the applicable standards of the
National Fire Protection Association,
in addition to the standards of any
other authorities having jurisdiction.
Failure to do so may impair the integ-
rity of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. The installing contractor or
sprinkler manufacturer should be
contacted relative to any questions.
The Model S170 Dry Pendent Sprin-
klers must only be installed in fittings
that meet the requirements of the De-
sign Criteria section.

Design
Criteria
The Model S170 Dry Sprinklers are
to be installed in the 1 inch NPT out-
let of a malleable iron threaded tee
fitting per ANSI B16.3 or cast iron
threaded tee fitting per ANSI B16.4
with the end sprinkler fitting on a
branch line to be plugged as shown
in Figure 1. Only use maximum
2-1/2 inch size reducing tee’s for dry
pipe sprinkler systems.
NOTES
Do not install the Model S170 into
any other type fitting without first con-
sulting the Technical Services De-
partment. Failure to use the appropri-
ate fitting may result in: failure of the
sprinkler to properly operate due to
formation of ice over the inlet Plug or
binding of the inlet Plug; or, insuffi-
cient engagement of the inlet pipe
threads with consequent leakage.
In the case of a dry pipe sprinkler
system subject to freezing, the use
of a fitting of other than the types
specified may result in failure of the
sprinkler to properly operate due to
the formation of ice over the Inlet.
Branch, cross, and feedmain piping
connected to Dry Sprinklers and sub-
ject to freezing temperatures must
be pitched for drainage in accord-
ance with the minimum requirements
of the National Fire Protection Asso-
ciation for dry pipe sprinkler systems.
When Dry Sprinklers are to be used
in wet pipe sprinkler systems protect-
ing areas subject to freezing tem-
peratures (e.g., sprinkler drops into
freezers), consideration must be
given to the appropriate length of the
sprinkler that will prevent freezing of
the water in the connecting pipes
due to conduction. When the tem-
perature surrounding the wet pipe
sprinkler system is maintained at a
minimum temperature of 40°F/4°C,
the following are the minimum recom-
mended lengths between the face of
the sprinkler fitting and the outside
surface of the protected area (i.e.,
length exposed to minimum ambient
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 mini-
mum recommended length from the
face of the fitting to the outside of
the protected area may be deter-
mined by interpolating between the
indicated values.
NOTE
When Dry Sprinklers penetrate a ceil-
ing into an area subject to freezing,
the clearance space around the
Sprinkler Casing must be completely
sealed in order to prevent the leak-
age of moist air into the freezing
area which might result in the forma-
tion 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 com-
ponents and, consequently, either
an inadvertent operation of the sprin-
kler or impaired operation due to re-
duced thermal sensitivity.

Installation
The Model S170 must be installed in
accordance with the following instruc-
tions:
NOTES
The Model S170 must only be in-
stalled in fittings that meet the re-
quirements of the Design Criteria
section.
Refer to the Design Criteria section
for other important requirements re-
garding 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 di-
ameter of the air bubble is approxi-
mately 1/16 inch (1,6 mm) for the
135°F/57°C rating to 1/8 inch (3,2
mm) for the 360°F/182°C rating.
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 sprinkler
inlet with consequent leakage
or impairment of the sprinkler.
Do not attempt to compensate
for insufficient adjustment in an
Escutcheon Plate by under- or
over-tightening the Sprinkler.
Readjust the position of the
sprinkler fitting to suit.
Step 1. The sprinkler must be
installed only in the pendent po-
sition and with the deflector par-
allel to the mounting surface.
Step 2. With pipe thread
sealant applied to the pipe
threads, hand tighten the sprin-
kler 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 1).

Step 4. After a suspended ceiling
has been installed or the finish coat
has been applied to a fixed ceiling
(as applicable), slide on the outer
piece of the Escutcheon until it
comes in contact with the ceiling. Do
not lift the ceiling panel out of its nor-
mal position.
In the case of the outer piece of the
Deep Ceiling Escutcheon, hold the
outer piece in contact with the mount-
ing surface (ceiling), and then rotate
the inner piece approximately 1/4
turn with respect to the outer piece,
to hold the Deep Escutcheon firmly
together.
Care &
Maintenance
The Model S170 must be maintained
and serviced in accordance with the
following instructions:
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 situ-
ation.
Before closing a fire protection sys-
tem main control valve for mainte-
nance work on the fire protection sys-
tem which it controls, permission to
shut down the affected fire protec-
tion systems must be obtained from
the proper authorities and all person-
nel who may be affected by this ac-
tion must be notified.
A Vent Hole is provided in the Bulb
Seat (Ref. Figure 2) 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 O-ring seal and,
therefore, it is an indication that the
sprinkler needs to be removed for de-
termining the cause of leakage (e.g.
an improper installation or an ice
plug). The fire protection system con-
trol valve must be closed and the
system drained 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
shipped or stored where their tem-
perature will exceed 100°F/38°C and
they must never be painted, plated,
coated, or otherwise altered after
leaving the factory. Modified sprin-
klers must be replaced. Sprinklers
that have been exposed to corrosive
products of combustion, 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
damage - before, during, and after
installation. Sprinklers damaged by
dropping, striking, wrench twist/slip-
page, 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 Sec-
tion).
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 installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
