RD208 : flat concealed sprinkler Model RD208 are automatic nozzles of the compaction type welding. This is decorative and responsive. The heat-reactive element, etc., is in turn concealed above the ceiling. The cover plate has a flat profile, and its diameter is extremely small (2-5/8 inch, 68mm). The push and/or threaded, threaded design of the concealed plate assembly allows for easy mounting of the cover plate. The Model RD208 should therefore be your first choice when aesthetics are the primary consideration for ultimate appeal and outstanding performance is desired. Model RD208 is designed for residential areas and it is perfect for use in homes, hotels and other residences. Model RD208 will be used in wet pipe civil sprinkler systems for Single and Two Family Houses and Manufacturers per NFPA 13D; wet pipe civil sprinkler systems for residential occupations up to and including four height stories per NFPA 13R; or, wet pipe sprinkler systems for residential sections of any profession in each NFPA 13. Model RD208 has a K-factor of 4.9 (70.6 LPM/) to meet residential flow rates needed required with minimal residual pressure, allowing for smaller pipe sizes and water supply requirements. For extended installation flexibility, Model RD208 offers 1/2 inch (12.8mm) vertical adjustment. This adjustment in the setting reduces the need to precisely cut the pipe falling to the sprinkler and allows for a perfect fit over a wide range of pipe lengths. The heat sensitivity and water distribution design of the Model RD208 allows for increased occupants' ability to escape or evacuate in the event of a fire. However, a civil fire sprinkler system is not a substitute for awareness of fire safety or building fire safety according to building regulations. The Free Act is defined in the Drinking Water Lead Reduction Act (S.3874) endorsed by the Water Utilities Council of AWWA and California Assembly Bill # 1953 as having less than or equal to an average of 0 .25% lead on wetted surfaces of pipes, plumbing fittings and fixtures.
