to be used in accordance with DMX core cable charts (Appendix F).
Equivalents to Belden specifications may be considered.
 Untwisted cable is not allowed for any audio application.
 All wiring runs are to be concealed in ceiling and walls whenever

corners or hidden by trim. All bends in wiring will be 90 degrees, and
exposed wires must either run parallel or perpendicular to the floor.
 Wires for a Head End shall not be run exposed down any wall. They shall
be in the wall or in a wire management tray or chase.
 Exposed wiring shall be attached to walls and ceiling by staples securely
enough to avoid wire sagging.
 All wiring that runs horizontally above drop tile ceiling shall be supported
every 4 to 5 feet to protect the cable from the stress related to its own
weight and resulting sag.
 Cable shall not be tied to ceiling support system, sprinkler pipes or
electrical conduit.
 Wire dress at the head end shall have signal separation spacing observed.
 Wires exiting a wall will have a trim plate.
 Any retrofit installation shall have a new wiring infrastructure (all wiring
except 110V mains) pulled.
 All wiring will be run so that it’s kept at a safe distance from possible
interference sources as specified in Appendix C “Cable Pulls”.
