IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Series TY-B – 2.8, 5.6, and 8.0 K-factor
Upright, Pendent, and Recessed Pendent Sprinklers
Standard Response, Standard Coverage
General
Description
The TYCO Series TY-B 2.8, 5.6,
and 8.0 K-factor, Upright, Pendent,
and Recessed Pendent Sprin-
klers described herein are standard
response, standard coverage, decora-
tive 5 mm glass bulb-type spray sprin-
klers. They are designed for use in light,
ordinary, or extra-hazard commercial
occupancies such as banks, hotels,
shopping malls, factories, reneries,
and chemical plants.
The TY-B Recessed Pendent Sprinkler,
where applicable, is intended for use in
areas with a nished ceiling. It uses a
two-piece Style 10 (1/2 in. NPT) or Style
40 (3/4 in. NPT) Recessed Escutcheon.
The Recessed Escutcheon provides
1/2 in. (12,7 mm) of recessed adjust-
ment or up to 3/4 in. (19,1 mm) of total
adjustment from the flush 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 what would 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 about the suitability of these
coatings for any given corrosive envi-
ronment. The effects of ambient tem-
perature, 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 2.8, 5.6, and 8.0 K-fac-
tor, Upright, Pendent, and Recessed
Pendent 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 maintain-
ing their fire protection system and
devices in proper operating condi-
tion. Contract the installing contrac-
tor or product manufacturer with any
questions.
NFPA 13 prohibits installation of 1/2 in.
NPT sprinklers with K-factors greater
than 5.6 in new construction. They are
intended for retrofit in existing sprinkler
systems only.

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
The TYCO Series TY-B 2.8, 5.6, and
8.0 K-factor, Upright, Pendent, and
Recessed Pendent Sprinklers 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 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) to
3/32 in. (2,4 mm) for the 360°F (182°C)
temperature ratings.
A leak-tight 1/2 in. NPT sprinkler
joint should be obtained by apply-
ing a minimum-to-maximum torque of
7 to 14 lb-ft (9,5 to 19,0 N·m). Obtain
a leak-tight 3/4 in. NPT sprinkler joint
by applying a minimum to maximum
torque of 10 to 20 lb-ft (13,4 to
26,8 N·m). Higher levels of torque may
distort the sprinkler inlet and cause
leakage or impairment of the sprinkler.
Do not attempt to compensate for
insufcient adjustment in the escutch-
eon plate by under- or over-tightening
the sprinkler. Readjust the position of
the sprinkler tting to suit.
Series TY-B Upright and Pendent
Sprinklers Installation
The Series TY-B Upright and Pendent
Sprinklers must be installed in accor-
dance with the following instructions:
Step 1. Install pendent sprinklers in the
pendent position. Install upright sprin-
klers in the upright position.
Step 2. With pipe thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step 3. Tighten the sprinkler into the
sprinkler tting using only the W-Type
6 Sprinkler Wrench, see Figure 7.
For wax-coated sprinklers, use an
8 or 10 in. adjustable wrench. With
reference to Figure 1 to 4, apply the
W-Type 6 Recessed Sprinkler Wrench
or an adjustable wrench, as applicable,
to the sprinkler wrench ats.
Wax Coated Sprinklers
When installing wax-coated sprinklers
with an adjustable wrench, take 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
flats without damaging the wax
coating.
• Before wrench tightening the sprin-
kler, adjust the jaws of the wrench
to contact only the sprinkler wrench
ats.
• After wrench tightening the sprin-
kler, loosen the wrench jaws before
removing the wrench.
After Installation
After installation, complete the
following:
• Inspect the sprinkler wrench ats
and frame arms and retouch (repair)
the wax coating whenever the coat-
ing has been damaged and bare
metal is exposed.
• Retouch the wax coating on the
wrench ats by gently applying a
heated 1/8 in. 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 it can begin to melt the wax,
and appropriate precautions need to be
taken when handling the heated rod in
order to prevent the installer from being
burned.
Series TY-B Recessed Pendent
Sprinklers
The Series TY-B Recessed Pendent
Sprinklers must be installed in accor-
dance with the following instructions:
Step 1. 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 2. Tighten the sprinkler into the
sprinkler tting using only the W-Type 7
Recessed Sprinkler Wrench, see Figure
8. With reference to Figure 3 or 4, apply
the W-Type 7 Recessed Sprinkler
wrench to the sprinkler wrench ats.
Step 3. After the ceiling is installed or
the nish coat is applied, slide on the
Style 10 or 40 Closure over the Series
TY-B Recessed Pendent Sprinkler
and push the Closure over the Mount-
ing Plate until its ange contacts the
ceiling.
Care and
Maintenance
The TYCO Series TY-B 2.8, 5.6, and
8.0 K-factor, Upright, Pendent, and
Recessed Pendent Sprinklers 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 sprin-
klers are not used for hanging any
objects and that the sprinklers are only
cleaned by means of gently dusting
with a feather duster; otherwise, non-
operation in the event of a re or inad-
vertent 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 other-
wise altered after leaving the factory.
Modied sprinklers must be replaced.
