IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cau-
tions with respect to handling and
installation of sprinkler systems and
components. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail

Description
TYCO Series TY-B, 2.8, 5.6, and 8.0
K-factor, Upright and Pendent Sprin-
klers described in this technical data
sheet are standard response, standard
coverage decorative 5 mm glass bulb
type spray sprinklers designed for use in
light, ordinary, or extra hazard, commer-
cial occupancies such as banks, hotels,
shopping malls, factories, reneries, and
chemical plants.
The recessed version of the Series TY-B
Pendent Sprinkler, where applicable, is
intended for use in areas with a nished
ceiling. It uses a two-piece Style 10 (1/2
inch NPT) or Style 40 (3/4 inch NPT)
Recessed Escutcheon. The Recessed
Escutcheon provides 1/2 inch (12,7 mm)
of recessed adjustment or up to 3/4 inch
(19,1 mm) of total adjustment from the
ush pendent position. The adjustment
provided by the Recessed Escutcheon
reduces the accuracy to which the xed
pipe drops to the sprinklers must be cut.
Corrosion resistant coatings, where
applicable, are utilized to extend the life
of copper alloy sprinklers beyond that
which would otherwise be obtained
when exposed to corrosive atmo-
spheres. Although corrosion resistant
coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing
is not representative of all possible
corrosive atmospheres. Consequently,
it is recommended that the end user
be consulted with respect to the suit-
ability of these coatings for any given
corrosive environment. The effects of
ambient temperature, concentration of
chemicals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
An intermediate level version of the
Series TY-B Pendent Sprinkler can be
obtained by utilizing the Series TY-B
Pendent Sprinkler in combination with
the Model S2 Shield.
NOTICE
The Series TY-B Sprinklers described
herein must be installed and maintained
in compliance with this document, as
well as with the applicable standards of
the National Fire Protection Association
(NFPA), in addition to the standards of
any other authorities having jurisdiction.
Failure to do so may impair the perfor-
mance of these devices.
The owner is responsible for maintaining
their fire protection system and devices
in proper operating condition. Contract
the installing contractor or product
manufacturer with any questions.

Operation
The glass bulb contains a uid which
expands when exposed to heat. When
the rated temperature is reached, the
uid expands sufciently to shatter the
glass bulb, allowing the sprinkler to
activate and water to ow.

Installation
TYCO Series TY-B, 2.8, 5.6, and 8.0
K-factor, Upright and Pendent Sprin-
klers must be installed in accordance
with this section.
General Instructions
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) for the 135°F (57°C) to 3/32
inch (2,4 mm) for the 360°F (182°C)
temperature ratings.
A leak-tight 1/2 inch NPT sprinkler
joint should be obtained by applying
a minimum-to-maximum torque of 7
to 14 ft.-lbs. (9,5 to 19,0 Nm). Obtain
a leak-tight 3/4 inch NPT sprinkler joint
by applying a minimum to maximum
torque of 10 to 20 ft.-lbs. (13,4 to 26,8
Nm). Higher levels of torque may distort
the sprinkler inlet and cause leakage or
impairment of the sprinkler.
Do not attempt to make-up for insuf-
cient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Readjust the position of the
sprinkler tting to suit.

Upright and Pendent Sprinklers
The Series TY-B Upright and Pendent
Sprinklers must be installed in accor-
dance with the following instructions:
Note: Install pendent sprinklers in the
pendent position; install upright sprin-
klers in the upright position.
Step 1. With pipe thread sealant applied
to the pipe threads, hand-tighten the
sprinkler into the sprinkler tting.
Step 2. Tighten the sprinkler into the
sprinkler tting using only the W-Type
6 Sprinkler Wrench (Figure 7). For
wax-coated sprinklers, use an 8 or 10
inch adjustable wrench. With reference
to Figures 1 through 4, the W-Type
7 Recessed Sprinkler Wrench or an
adjustable wrench, as applicable, is to
be applied to the sprinkler wrench ats.
When installing wax-coated sprinklers
with an adjustable wrench, exercise
care to prevent damage to the wax
coating on the sprinkler wrench ats
or frame arms and, consequently,
exposure of bare metal to the corrosive
environment. Open the jaws of the
wrench sufciently wide to pass over
the wrench ats without damaging the
wax coating. Before wrench tightening
the sprinkler, adjust the jaws of the
wrench to contact only the sprinkler
wrench ats. After wrench tightening the
sprinkler, loosen the wrench jaws before
removing the wrench.
After installation, inspect the sprinkler
wrench ats and frame arms and
retouch (repair) the wax coating when-
ever the coating has been damaged and
bare metal is exposed. Retouch the wax
coating on the wrench ats by gently
applying a heated 1/8 inch diameter
steel rod to the damaged areas of wax,
to smooth it back over areas where bare
metal is exposed.
NOTICE
Only retouching of the wax coating
applied to the wrench flats and frame
arms is permitted, and the retouching is
to be performed only at the time of the
initial sprinkler installation.
The steel rod should be heated only
to the point at which it can begin to
melt the wax, and appropriate precau-
tions need to be taken when handling
the heated rod in order to prevent the
installer from being burned.
Recessed Pendent Sprinklers
The Series TY-B Recessed Pendent
Sprinklers must be installed in accor-
dance with the following instructions:
Step A. After installing the Style 10
or 40 Mounting Plate, as applicable,
over the sprinkler threads and with
pipe thread sealant applied to the pipe
threads, hand-tighten the sprinkler into
the sprinkler tting.
Step B. Tighten the sprinkler into the
sprinkler tting using only the W-Type
7 Recessed Sprinkler Wrench (Figure
8). With reference to Figure 3 or 4, the
W-Type 7 Recessed Sprinkler Wrench
is to be applied to the sprinkler wrench
ats.
Step C. After the ceiling is installed or
the nish coat is applied, slide on the
Style 10 or 40 Closure over the Series
TY-B Sprinkler and push the Closure
over the Mounting Plate until its ange
contacts the ceiling.
Care and
Maintenance
TYCO Series TY-B, 2.8, 5.6, and 8.0
K-factor, Upright and Pendent Sprin-
klers must be maintained and serviced
in accordance with this section.
Before closing a re protection system
main control valve for maintenance
work on the re protection system that
it controls, obtain permission to shut
down the affected re protection system
from the proper authorities and notify all
personnel who may be affected by this
action.
The owner must assure that the
sprinklers are not used for hanging
any objects and that the sprinklers are
only cleaned by means of gently dust-
ing with a feather duster; otherwise,
non-operation in the event of a re or
inadvertent operation may result.
Absence of an escutcheon, which is
used to cover a clearance, may delay
the time to sprinkler operation in a re
situation.
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 otherwise
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. (Refer to Installation Section.)
The owner is responsible for the inspec-
tion, 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 Asso-
ciation (e.g., NFPA 25), in addition to
the standards of any other authorities
having jurisdiction. Contact the installing
contractor or product manufacturer with
any questions.
Automatic sprinklers are recommended
to be inspected, tested, and maintained
by a qualied Inspection Service in
accordance with local requirements
and/or national codes.
