PART 3 EXECUTION

3.1 GENERAL

SECTION 27 41 00 Page 22

Ft. Bragg, NC

Installation and connection of audio-visual system equipment, materials, cable and cable fittings shall be performed only by experienced audio-visual system installers. Each installer shall have access to a complete copy of the specifications at the job site.

All materials and equipment are to be installed in accordance with all applicable standards of the National Electrical Code, the Electrical Code of the governing local municipality, all other applicable local codes, and all safety codes and ordinances.

3.2 INSTALLATION

Cable within equipment racks shall be separated and routed in groups according to function: microphone circuits, intercom circuits, line level audio circuits, loudspeaker circuits, control circuits, and 120 volt AC power circuits. Cable shall be neatly arranged, but tight bundling which makes modifications difficult shall be avoided. Plastic cable ties shall be used for grouping of circuits.

Cable in conduit or other raceway shall be separated according to function:

microphone circuits and intercom circuits, line level audio circuits, loudspeaker circuits, control circuits, and 120 volt AC power circuits.

Control circuits may be installed in line level audio conduit where separate control conduit is not indicated on the drawings. Control circuits for loudspeaker volume control priority override relays may be installed with loudspeaker circuits. Intercom circuits may be installed in line level audio conduit where microphone level conduit is not installed.

At all connection points for all types of cable, pressure sensitive label strips of the appropriate letters and numbers shall be wrapped around each cable near its termination. These cable numbers and/or letters, and all transformer and pre-adjustment potentiometer identifiers, shall be given to the Acoustical Consultant for inclusion on the record audio diagrams.

Unless otherwise noted, all audio circuits shall be two wire with shield, with the red or white wire used for the "high" side of the line and connected to pin 2 of microphone connectors or to the "tip" of patch panel and other phone jacks. The black wire shall be used for the "low" side of the line and shall connect to pin 3 of microphone connectors or to the "ring" of phone jacks. The shield (drain) wire shall connect to pin 1 of microphone connectors or to the sleeve of phone jacks.

All audio circuits (red or white and black conductors) shall be ungrounded except as provided by single ended amplifier inputs and where grounding of unbalanced circuits is directed during system tests. Shields for line level audio circuits shall be grounded to rack sheet metal at each cable termination. Where line level audio circuits connect to audio transformers, shields shall connect to transformer electrostatic shields and case grounds.

At each cable termination shield or shield drain, wire length shall be approximately equal to the length of the insulated conductors. Shield drain wires shall be sheathed in green PVC sleeving. Circuit shields shall not otherwise connect to each other nor ground to electrical conduit at wall boxes, etc. Microphone circuit shields shall be grounded only at mixer inputs.

Equipment rack sheet metal ground shall only be via the insulated ground cable(s) noted on the drawings. Racks shall not otherwise connect to

SECTION 27 41 00 Page 23

Ft. Bragg, NC building steel or electrical conduit which is grounded to the building electrical system. Adjacent equipment racks shall be connected by an insulated #6 AWG ground cable which is bonded to each equipment rack.

Care shall be exercised in wiring so as not to damage cables and equipment.

Circuits shall not be spliced except as approved on shop drawings.

Where conduit connects between equipment rack locations, or between sound console and equipment racks, at least two spare circuits of each type in the conduit (microphone level, line level, or control) shall be installed in each conduit used. All spare circuit conductors shall be connected to chassis ground at the downstream (e.g. power amplifier) end of the cable.

Where resistors are indicated to terminate an audio circuit, install each resistor at the end of the line at the input to the following transformer or amplifier. High impedance circuits shall not extend more than 20 feet.

All wire joints and connections in the audio system shall be made with rosin core solder and a small soldering iron; or with approved mechanical connectors. Soldering shall be neat and shall not exhibit "cold" solder joints. Connections to screw type terminals shall be made with mechanically connected, uninsulated, spade type lugs selected for the particular wire size in use.

Connections made with miniature screw actuated, pressure type terminal strips (such as at the rear of IED or PTA line amplifier cardfiles) shall be made by stripping approximately ¼-inch of insulation from stranded conductor, inserting the untinned wire into the pressure terminal, and tightening the terminal screw using a small screwdriver which securely fits the screw head.

All crimp type connectors, including insulated butt connectors for inline loudspeaker circuit connections, shall be crimped with a Thomas & Betts model WT111M tool. Spade tongue terminals shall be crimped with the notch on the barrel opposite the seam.

Loudspeakers shall be installed so there are no obstructions to the loudspeaker coverage pattern. Loudspeakers shall be connected "in phase" and proper impedance matching shall be maintained between amplifiers and loudspeakers. As required for proper acoustic levels and proper aiming, re-tap selected loudspeaker transformers and re-orientate selected loudspeakers or loudspeaker clusters as later directed by the Contracting Officer’s Representative during final system tests and adjustments.

Tie-wrap and secure all loudspeaker line matching transformer leads and loudspeaker cable away from loudspeakers to prevent "rattling" when loudspeakers are energized.

All video circuits, except as indicated otherwise, shall be single conductor shielded, 75-ohm coaxial cable. Shields for video circuits shall be grounded only at the connected equipment and shall not ground at electrical conduit at wall boxes, etc.

No soldering of video connectors will be permitted.

SECTION 27 41 00 Page 24

Ft. Bragg, NC

All video connections shall be made with a specified BNC type connector.

The BNC plug center pin shall be crimped with a Trompeter 010 0055 or Buchanan 613439 crimp tool.

After the video system has received its preliminary testing by the Systems Contractor and is found to be operating properly, without hum, distortion, oscillations, etc., each video camera will be tested for proper tracking and each video monitor will be tested for sync stability, proper gray scale, convergence, and color temperature. Equalization of the video system will also involve setting video amplifiers so the video blanking level is at 1.0 volt peak-to-peak throughout the video system.

At the time of system testing and equalization, a qualified technician shall be available to realign the video projectors if so requested by the Contracting Officer’s Representative.

3.3 NAMEPLATES

All control panels, all patch panels, and all controls, jacks, microphone receptacles, switches, etc. (except for controls, etc., on audio equipment which are properly identified by the manufacturer) shall be suitably identified by engraved panels, engraved plates, Metal-photo panels, or Metal-photo plates. Engraved panels or plates shall be filled with a suitable contrasting color as approved on shop drawings. Do not mark on patch panel paper designation strip; for Owner's use only.

Room numbers shown on drawings and indicated on control panel details, patch panels, etc., are architectural room numbers for identification only during the…
