General
Description
The TYCO Series TY-B, 5.6 K-factor,
Upright (TY315) and Pendent (TY325)
Sprinklers described in this data sheet
are standard response, standard cover-
age, decorative 5 mm glass bulb type
spray sprinklers designed for use in
light, ordinary, or extra hazard, com-
mercial occupancies such as banks,
hotels, shopping malls, factories,
refineries, and chemical plants.
The recessed version of the Series
TY-B Pendent Sprinkler, where appli-
cable, is intended for use in areas with a
finished ceiling. This recessed pendent
sprinkler uses one of the following:
• A two-piece Style 15 Recessed
Escutcheon with recessed adjust-
ment up to 5/8 inch (15,9 mm) from
the flush pendent position.
• A two-piece Style 20 Recessed
Escutcheon with recessed adjust-
ment up to 1/2 inch (12,7 mm) 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.
Intermediate level versions of Series
TY-B Sprinklers are described in
Technical Data Sheet TFP352. Sprinkler
guards and shields are described in
Technical Data Sheet TFP780.
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 dam-
age 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.
