UNIVAL UVFDC series is UL 405 Listed and FM 1510 Approved. LFB accepts listed FDCs with factory submittal, ADB and BS 9990 compliance letter, NFPA 14 Section 8.17 documentation and hydrostatic test report. Sign identification per NFPA 14 Section 8.17.1 required on the installation.<\/p>\n<p><strong>2-way vs 3-way FDC for London?<\/strong> 2-way (UVFDC-2W-2.5) satisfies minimum NFPA 14 requirement for Class I\/III standpipes up to 500 gpm and NFPA 13 sprinkler systems. 3-way (UVFDC-3W-2.5) provides additional capacity for high-rise systems over 500 gpm or combined standpipe\/sprinkler where engineer specifies extra inlet per NFPA 14 Section 8.17.2.<\/p>\n<p><strong>Storz vs threaded inlets?<\/strong> Threaded (UVFDC-2W, UVFDC-3W) uses BS 336 2.5 inch instantaneous round male coupling for standard 2-way and 3-way inlets per LFB spec, compatible with existing LFB threaded hose. Storz (UVFDC-STZ4-W, UVFDC-STZ5-W) uses 4 inch or 5 inch quick-connect with sexless coupling, allows rapid connection without threading but requires LFB Storz spanner. Storz 70 mm and 100 mm quick-connect inlets optional; LFB default is BS 336 instantaneous.<\/p>\n<p><strong>Wall vs freestanding vs flush sidewalk?<\/strong> Wall-mount (UVFDC-2W, UVFDC-3W) is standard for buildings with exterior wall frontage. Freestanding (UVFDC-2W-FS) on pedestal post is required where wall mount is impossible (parking garages, set-back buildings, interior courtyards). Flush sidewalk (UVFDC-SIDE-2W) is required for narrow frontage where wall and pedestal are both impractical, with hinged cover plate to match sidewalk finish.<\/p>\n<p><strong>What is the pressure rating?<\/strong> Standard UVFDC is 300 psi working pressure with 600 psi hydrostatic test per UL 405. High-pressure option UVFDC-HP rated 400 psi working for industrial high-pressure loops. Internal clapper check rated same pressure class as body.<\/p>\n<p><strong>What is the delivery time to London?<\/strong> Stock UVFDC-2W-2.5 with standard NH thread ships 2 to 3 weeks. Custom thread forms (Quebec, NYC, Boston, Storz) factory-built 3 to 5 weeks. Freestanding UVFDC-2W-FS with pedestal 4 to 6 weeks. Flush sidewalk UVFDC-SIDE-2W 4 to 6 weeks.
