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, re neries, and chemical plants.
The recessed version of the Series TY-B Pendent Sprinkler, where appli- cable, is intended for use in areas with a nished 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 ush pendent position.
- A two-piece Style 20 Recessed Escutcheon with recessed adjust- ment up to 1/2 inch (12,7 mm) 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.
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.
