LFII 4.2 K-factor Residential Flush Pendent Sprinklers
General Description
The Series LFII Residential Flush Pendent Sprinklers are decorative, fast response, fusible solder sprinklers designed for use in residential occupancies such as homes, apartments, dormitories, and hotels. The Series LFII are to be used in wet pipe residential sprinkler systems for one and two family dwellings and manufactured homes per NFPA 13D; wet pipe residential sprinkler systems for residential occupancies up to and including four stories in height per NFPA 13R; or, wet pipe sprinkler systems for the residential portions of any occupancy per NFPA 13.
The 4.2 K-factor provides the required residential flow rates at reduced pressures, enabling smaller pipe sizes and water supply requirements. The flush design features a separable escutcheon providing 3/8 inch vertical adjustment. This adjustment reduces the accuracy to which the pipe drops to the sprinklers must be cut to help assure a perfect fit installation.
IMPORTANT Always refer to Technical Data Sheet TFP700 for the INSTALLER WARNING that provides cautions with respect to handling and installation of sprinkler systems and components. Improper handling and installation can permanently damage a sprinkler system or its components and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely.
