Code and listing acceptance for NYC
NYC Building Code. The NYC Building Code adopts NFPA 13 with NYC amendments and requires UL/FM listed wet alarm valves on all automatic wet pipe sprinkler installations in NYC. UVW-1511-300 meets UL 193 and FM Class 1041 listing requirements.
FDNY acceptance. FDNY Technical Memorandum requires manufacturer’s certification of UL/FM listing for every sprinkler riser component. ValveAtlas provides UL and FM certificates for every shipment.
High-rise Zone 2/Zone 3 standpipe and sprinkler. Manhattan high-rise Zone 2 and Zone 3 sprinkler systems require 500 psi CWP-rated wet alarm valves at the zone isolation. UVW-1511-500 is rated for these supertall sprinkler risers.
Public buildings and schools. NYC public building and school construction projects standardize on UL/FM listed wet alarm valves with complete trim assemblies.
