HANGERS AND SUPPORTS <br />FOR ELECTRICAL SYSTEMS <br />Section 16012 <br />15-1207 <br />A. Penetrations: Provide through -penetration firestop systems that are installed to <br />resist the spread of fire, passage of smoke and other hot gases according to <br />requirements indicated, to restore the original fire -resistance rating of assembly <br />penetrated. <br />1. Install complete through penetration firestop systems that have been <br />tested and are listed by recognized testing agencies per ASTM E 814 or <br />UL 1479 fire tests in a configuration that is representative of site <br />conditions. <br />2. F -Rated Systems: Install through -penetration firestop systems with F - <br />ratings indicated, as determined per ASTM E 814 or UL 1479, but not <br />less than the fire resistance rating of the assembly being penetrated. <br />3. T -Rated Systems: Install through -penetration firestop systems with T- <br />racings indicated, as well as F -ratings, as determined per ASTM E 814 or <br />UL 1479, where required by the Building Code. <br />1.6 SUBMITTALS <br />A. Shop Drawings: Indicate system layout with location and detail of trapeze <br />hangers. <br />B. Product Data: <br />1. Hangers and Supports: Submit manufacturers catalog data including load <br />capacity. <br />2. Firestopping: Submit data on product characteristics, performance and <br />limitation criteria. <br />C. Firestopping Schedule: Submit schedule of opening locations and sizes, <br />penetrating items, and required listed design numbers to seal openings to <br />maintain fire resistance rating of adjacent assembly. <br />D. Design Data: Indicate load carrying capacity of trapeze hangers and hangers and <br />supports. <br />E. Manufacturer's Installation Instructions: <br />1. Hangers and Supports: Submit special procedures and assembly of <br />components. <br />2. Firestopping: Submit preparation and installation instructions. <br />F. Manufacturer's Certificate: Certify products meet or exceed specified <br />requirements. <br />G. Engineering Judgements: For conditions not covered by UL or WH listed <br />designs, submit judgements by licensed professional engineer suitable for <br />presentation to authority having jurisdiction for acceptance as meeting code fire <br />protection requirements. <br />1.7 SEISMIC DETAILS AND CALCULATIONS <br />2 <br />
