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.

TY-B Sprinklers are described in
Technical Data Sheet TFP352. Sprinkler
guards and shields are described in
