  • Series LFII Residential Sprinklers Flat-Plate Concealed Pendent4.9 K-Factor 

    The TYCO RAPID RESPONSE Series LFII Residential Flat-PlateConcealed Pendent Sprinklers (TY2524) are decora­tive, fast response, fusiblesolder sprin­klers designed for use in residential oc­cupancies such as homes,apartments, dormitories, and hotels.

    The Cover Plate/Retainer Assembly con­ceals the sprinkleroperating compo­nents above the ceiling. The flat profile of the Cover Plateprovides the optimum aesthetically appealing sprinkler design. Additionally,the concealed design of the Series LFII Residential Flat-Plate Con­cealedPendent Sprinklers provides 1/2 inch (12,8 mm) vertical adjustment. Thisadjustment provides a measure of flex­ibility when cutting fixed sprinklerdrops.

    The Series LFII Residential Flat-Plate Concealed PendentSprinklers are in­tended for use in the following systems:

    • wet and dry pipe residential sprin­kler systems for one- andtwo-fam­ily dwellings and mobile homes per NFPA 13D

    • wet and dry pipe residential sprin­kler systems for residentialoccu­pancies up to and including four sto­ries in height per NFPA 13R

    • wet and dry pipe sprinkler systems for the residential portionsof any occupancy per NFPA 13. 

    Historically, residential sprinklers, based on their Listing, havebeen limited to wet pipe sprinkler systems to assure speed of water deliveryfor a given pre­scribed design area (number of design sprinklers).

    The Listing for the Series LFII Residen­tial Flat-Plate ConcealedPendent Sprin­kler now offers the laboratory approved option of designing drypipe residential sprinkler systems.

    For dry systems, as described in U.S. Patent 7,712,543, throughextensive testing it has been determined that the number of design sprinklers(hydrau­lic design area) for the Series LFII Resi­dential Flat-Plate ConcealedSprinklers (TY2524) need not be increased over the number of design sprinklers(hydrau­lic design area) specified for wet pipe sprinkler systems, as iscustomary for density/area sprinkler systems designed per NFPA 13, 13D, or 13R.

    Consequently, the Series LFII Residen­tial Flat-Plate ConcealedSprinklers (TY2524) offer the features of non-wa­ter filled pipe in addition tonot having to increase the number of design sprinklers (hydraulic design area)for systems de­signed to NFPA 13, 13D, or 13R. Non-water filled pipe willpermit options for areas sensitive to freezing.

    The Series LFII Residential Flat-Plate Concealed Pendent Sprinklerhas a 4.9 (70,6) K-factor that provides the required residential flow rates atreduced pres­sures, enabling smaller pipe sizes and water supply requirements.

    This sprinkler has been designed with heat sensitivity and waterdistribution characteristics proven to help in the con­trol of residentialfires and to improve the chance for occupants to escape or be evacuated.

    The Series LFII Residential Flat-Plate Concealed PendentSprinklers are shipped with a Disposable Protective Cap. The Protective Capprotects the sprinkler during ceiling installation or finish. After ceilinginstallation is com­plete, the Protective Cap is removed  and the Cover Plate/Retainer Assem­bly isinstalled. Removing the Protec­tive Cap is required for proper sprinklerperformance.
