Dry sprinkler RAPID RESPONSE Series

TYCO RAPID RESPONSE Series LFII Residential 4.9K Pendent and Recessed Pendent Sprinklers (TY2234) are decorative, fast response, frangible bulb sprinklers designed for use in residential occupancies such as homes, apartments, dormitories, and hotels. When aesthetics and optimized flow characteristics are the major consideration, the Series LFII Residential Sprinklers (TY2234) should be the first choice. The Series LFII Residential Sprinklers are intended for use in the following scenarios: • wet and dry pipe residential sprinkler systems for one- and two-family dwellings and mobile homes per NFPA 13D • wet and dry pipe residential sprinkler systems for residential occupancies up to and including four stories in height per NFPA 13R • wet and dry pipe sprinkler systems for the residential portions of any occupancy per NFPA 13 The recessed version of the Series LFII Residential Sprinklers is intended for use in areas with finished ceilings. It employs a two-piece Style 20 Recessed Escutcheon. The Recessed Escutcheon provides 1/4 in. (6,4 mm) of recessed adjustment or up to 1/2 in. (12,7 mm) of total adjustment from the flush ceiling position. The adjustment provided by the Recessed Escutcheon reduces the accuracy to which the pipe drops to the sprinklers must be cut. The Series LFII Residential Sprinklers have been designed with heat sensitivity and water distribution characteristics proven to help in the control of residential fires and to improve the chance for occupants to escape or be evacuated.
