2. Do not untwist UTP cables more than 1/2 inch from the point of termination to maintain

cable geometry.

1. Install cabling with horizontal and vertical cable guides in telecommunications spaces with

terminating hardware and interconnection equipment.

2. Suspend UTP cable not in a wireway or pathway a minimum of 8 inches above ceilings by

cable supports not more than 60 inches apart.

3. Cable shall not be run through structural members or in contact with pipes, ducts, or other

potentially damaging items.

F. Group connecting hardware for cables into separate logical fields.

G. Separation from EMI Sources:

communication cable from potential EMI sources, including electrical power lines and

equipment.

3. Separation between communications cables in grounded metallic raceways and unshielded

power lines or electrical equipment shall be as follows:

a. Electrical Equipment Rating Less Than 2 kVA: A minimum of 2-1/2 inches.



4. Separation between communications cables in grounded metallic raceways and power lines

and electrical equipment located in grounded metallic conduits or enclosures shall be as

follows:

a. Electrical Equipment Rating Less Than 2 kVA: No requirement.



5. Separation between Communications Cables and Electrical Motors and Transformers, 5

kVA or HP and Larger: A minimum of 48 inches.


6. Separation between Communications Cables and Fluorescent Fixtures: A minimum of 5

inches.

3.3 FIRESTOPPING

A. Contractor must fire stop the inside of the pipes that they use. The exterior of the pipes will be fire

stopped by the electrical contractor.

3.4 GROUNDING

A. Install grounding according to BICSI TDMM, "Grounding, Bonding, and Electrical Protection"

Chapter.


C. Locate grounding bus bar to minimize the length of bonding conductors. Fasten to wall allowing

at least 2-inch clearance behind the grounding bus bar. Connect grounding bus bar with a minimum

No. 4 AWG grounding electrode conductor from grounding bus bar to suitable electrical building

ground.

D. Bond metallic equipment to the grounding bus bar, using not smaller than No. 6 AWG equipment

grounding conductor.

E. The No.4 AWG to the communicator room will be provided by the electrical contractor

F. The cabling contractor must provide a ground bar in each communication room.

3.5 IDENTIFICATION

A. Cabling Administration Drawings: Show building floor plans with cabling administration-point

labeling. Identify labeling convention and show labels for telecommunications closets, backbone

pathways and cables, entrance pathways and cables, terminal hardware and positions, horizontal

cables, work areas and workstation terminal positions, grounding buses and pathways, and

equipment grounding conductors. Follow convention of TIA-606-A. Furnish electronic record of

all drawings, in software and format selected by Owner.

B. Cable and Wire Identification:

1. Label each cable within 4 inches of each termination and tap, where it is accessible in a

cabinet or junction or outlet box, and elsewhere as indicated.

2. Each wire connected to building-mounted devices is not required to be numbered at device

if color of wire is consistent with associated wire connected and numbered within panel or

cabinet.

3. Label each terminal strip and screw terminal in each cabinet, rack, or panel.

4. Individually number wiring conductors connected to terminal strips, and identify each

cable or wiring group being extended from a panel or cabinet to a building-mounted device

shall be identified with name and number of particular device as shown.

5. Label each unit and field within distribution racks and frames.


C. Labels shall be preprinted or computer-printed type with printing area and font color that contrasts

with cable jacket color but still complies with requirements in TIA-606-A.

1. Cables use flexible vinyl or polyester that flex as cables are bent.

3.6 FIELD QUALITY CONTROL

A. Tests and Inspections:

1. Visually inspect UTP cable jacket materials for NRTL certification markings. Inspect

cabling terminations in communications equipment rooms for compliance with color-

coding for pin assignments, and inspect cabling connections for compliance with TIA-

568.1-D.

2. Visually confirm Category 6, marking of outlets, cover plates, outlet/connectors, and patch

panels.

3. Visually inspect cable placement, cable termination, grounding and bonding, equipment

and patch cords, and labeling of all components.

4. Test UTP backbone copper cabling for DC loop resistance, shorts, opens, intermittent

faults, and polarity between conductors. Test operation of shorting bars in connection

blocks. Test cables after termination but not cross-connection.

5. UTP Performance Tests:

a. Test for each outlet with a level 3 cable analyzer.

1). Wire map.
