Upright, Pendent, and Recessed Pendent Sprinklers

The Series TY-B, 2.8, 5.6, and 8.0 K-factor, Upright and PendentSprinklers described in this data sheet are standard response - standardcoverage, decorative 5 mm glass bulb type spray sprinklers designed for use in light,ordinary, or extra hazard, commercial occupancies such as banks, hotels,shopping malls, factories, refineries, chemical plants, etc. The recessedversion of the Series TY-B Pendent Sprinkler, where applicable, is intended foruse in areas with a finished ceiling. It uses a two-piece Style 10 (1/2 inchNPT) or Style 40 (3/4 inch NPT) Recessed Escutcheon. 

The Recessed Escutcheonprovides ½ inch (12,7 mm) of recessed adjustment or up to 3/4 inch (19,1 mm) oftotal adjustment from the flush pendent position. The adjustment provided bythe Recessed Escutcheon reduces the accuracy to which the fixed pipe drops tothe sprinklers must be cut. 

Corrosion resistant coatings, where applicable, areutilized to extend the life of copper alloy sprinklers beyond that which wouldotherwise be obtained when exposed to corrosive atmospheres. Although corrosionresistant coated sprinklers have passed the standard corrosion tests of theapplicable agencies, the testing is not representative of all possiblecorrosive atmospheres. Consequently, it is recommended that the end user be consultedwith respect to the suitability of these coatings for any given corrosive environment.The effects of ambient temperature, concentration of chemicals, and gas/chemicalvelocity, should be considered, as a minimum, along with the corrosive natureof the chemical to which the sprinklers will be exposed.

An intermediate level version of the Series TY-B Pendent Sprinklercan be obtained by utilizing the Series TY-B Pendent Sprinkler in combinationwith the Model S2 Shield.
