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 Sprinklers
described in herein are standard
response, standard coverage, decora­tive 5 mm glass bulb-type spray sprin­klers. They are designed for use in light,
ordinary, or extra-hazard commercial
occupancies such as banks, hotels,
shopping malls, factories, refineries,
and chemical plants.

The TY-B Recessed Pendent Sprinkler,
where applicable, is intended for use in
areas with a finished 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 adjust­ment 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 fixed 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 atmo­spheres. Although corrosion-resistant
coated sprinklers have passed the
standard corrosion tests of the appli­cable approval agencies, the testing
is not representative of all possible
corrosive atmospheres. Consequently,

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 instal­lation of sprinkler systems and com­ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo­nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

it is recommended that the end-user be
consulted about the suitability 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 2.8, 5.6, and 8.0 K-fac­tor, 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 perfor­mance 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.

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.
