d. Progress Set of Project Record Documents
4. Mounting - Mount equipment and enclosures plumb and square. Ensure that permanently
installed equipment is firmly and safely held in place. Design equipment supports to support
loads imposed with project safety factor of 5 or greater. For devices hung overhead, obtain
review by Structural Engineer licensed to practice in State of Texas.
5. Minor Equipment Moves - The process of equalizing and testing Audio Visual systems may
necessitate moving and adjusting certain component parts such as loudspeakers. Perform
requested minor moves during Final Tests and Adjustments without claim for additional
payment.
6. Dimension Verification - Verify dimensions and space requirements to assure that proper
mounting, clearance, and maintenance access space is available for system components.
7. Grommets - Cover edges of cable pass-through holes in chassis, rack, boxes, etc. with
rubber grommets or Brad GRNY nylon grommets.
8. Future Maintenance Access — Install equipment rack and mixing consoles allowing access
to rear connections by maintenance personnel without removal or disconnection of
equipment. Install field devices and field wiring such that maintenance personnel can access
terminations and splices without special equipment or disconnection of installed equipment.
9. Coordination - Coordinate work with other trades to avoid delays in construction schedule.
Meet construction schedule.
10. Clean-Up - Leave project clean each day. Place debris where designated by General
Contractor. Debris includes but not limited to: solder splatter, cable ends, stripped insulation,
spent crimp connectors, gypsum board and ceiling tile dust, and product wrappings and
cartons. After completion of installation, thoroughly clean areas worked, including non-visible
areas such as equipment rack interiors, rack top panels, and inside lockable floor and wall
boxes.
B. Labeling
1. Equipment Labels - Provide engraved lamicoid labels on front and rear of rack-mounted
equipment. Mount labels plumb and square. Include schematic reference design, item name,
and system or area controlled by labeled component. On program pre amps and mixers,
provide label for each input indicating which source is controlled by labeled channel. Unless
otherwise indicated, provide permanently-mounted black labels engraved with 118-inch
white block characters. Handwritten, self-laminating, or embossed plastic (Dymo) labels are
not acceptable. Provide labels for major equipment with 3 lines (minimum) of engraving,
coded as follows.
a. Line 1: Generic name of device, such as VIDEO MATRIX SWITCHER.
b. Line 2: Schematic designation of device, such as AV-MSW-1.
2. Control Labels - Provide engraved label over each user-operated control that describes the
function or purpose of control. Provide label of proper size to fit available space.
3. Terminal Strip Labels - Label each terminal strip with unique identification code in addition to
numerical label (Cinch MS series) for each terminal. Show terminal strip codes on system
schematic drawings included with Project Record Documents.
4. Rear Equipment Labels - Provide adhesive label on rear of equipment where cables attach,
to indicate designation of cable connected at each point.
5. Cable and Wire Labels - Label cables and wiring logically, legibly and permanently for easy
identification. Labels on cables to be adhesive strip type, covered with clear heat shrink
tubing. Factory stamped heat shrink tubing may be used. Hand-written or self-laminating
type labels are not acceptable.
6. Cable Label Codes and Locations - Label each cable with unique alpha-numeric code.
Locate cable designation at start and end of each cable run, within 3 inches of termination
point. For cable runs that have intermediate splice points, label cable with same designation
throughout, with additional suffix to indicate each segment of run. Provide cable designation
codes to schematic drawings included with Project Record Documents and Operation and
Maintenance Manuals.
C. Power and Grounding
1. Power Coordination - Coordinate final connection of power and ground wiring to rack.
Electrical contractor will provide power to sound and audio visual systems. Before
installation, verify load requirements for systems as accepted.
2. Bus Bars - Install 1-inch by Y4-inch copper ground bus bar, top to bottom in each rack.
Ground equipment chassis of each rack-mounted component without three-pin grounding
plug to bus bars with #12 AWG insulated green wire using 6-32 or larger nuts, bolts, lock
