City of Santa Ana Public Library Renovation <br />Group 4 Architecture Research + Planning, Inc.Smith, Fause & McDonald Inc. <br />Group 4 Project No. 22575-01 Conform Set – August 2, 2024Bid Set Addendum-03 – June 05 <br />INTEGRATED AUDIOVISUAL SYSTEMS AND EQUIPMENT SECTION 27 4116-65 <br />G.Apply a chemically inert lubricant to all wire and cable prior to pulling in conduit. Do not <br />subject wire and cable to tension greater than that recommended by the manufacturer. Use <br />multi-spool rollers where cable is pulled in place around bends. Do not pull reverse bends. <br />H.Provide a box loop for all wire and cable routed through junction boxes or distribution panels. <br />Provide tool formed thermal expansion loops at cable at manholes, handholes and at both <br />sides of all fixed mounted equipment. Cable loops and bends shall not be bent at a radius <br />greater than that recommended by the manufacturer. <br />I.Secure all wire and cable run vertically for continuous distances greater than thirty (30) feet. <br />Secure robust non-coaxial cables with screw-flange nylon cable ties or similar devices <br />appropriate to weight of cable. For all other cables, provide symmetrical conforming <br />nonmetallic bushings or woven cable grips appropriate to weight of cable. <br />3.5 SIGNAL POLARITY CONVENTION <br />A.Maintain consistent absolute signal polarity at all connectors, patch points and connection <br />points accessible in the system. Comply with AES26-2001.Where applicable, a positive <br />polarity electrical signal shall yield positive acoustic pressure from the loudspeakers. <br />B.Audio signal connector convention: Comply with AES 14-1992 (r1998) <br />Signal Connector Wire <br />Signal Phase Pin 2 Red or White <br />Signal Anti-Phase Pin 3 Black <br />Signal Ground Pin 1 Drain Wire <br />C.Video and RF/MATV Connector Convention: <br />Signal Connector Wire <br />Signal Phase Center Pin Center conductor <br />Signal Anti-Phase Shell Shield <br />Signal Ground Shell Shield <br />3.6 WIRING PRACTICE <br />A.Land all non-coaxial field wiring entering each equipment rack at specified terminal devices <br />prior to connection to any equipment or devices within racks. At Contractor's option, such <br />terminals may be located in the equipment racks or in the terminal cabinets provided. <br />Coordinate such selection with Project construction sequence and test procedures specified <br />herein. <br />B.Identify all wire and cable clearly with permanent labels wrapped about the full circumference <br />within one (1) inch of each connection. Indicate the number designated on the associated <br />field or shop drawing or run sheet, as applies. Assign wire or cable designations consistently <br />throughout a given system. Each wire or cable shall carry the same labeled designation over <br />its entire run, regardless of intermediate terminations. Conform with the requirements of <br />Section 27 05 00. <br />C.Apply all crimp connectors only with manufacturer's recommended ratchet type tooling and <br />correct crimp dies for connector and wire size. Plier type crimp tooling shall not be <br />acceptable. <br />D.Coordinate insulation displacement (quick connect) terminal devices with wire size and type. <br />Comply with manufacturer's recommendations. Make connections with automatic impact <br />type tooling set to recommended force.
