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

a. 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.

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

5. Identification within Connector Fields in Equipment Rooms and Wiring Closets: Label each connector and each discrete unit of cable!terminating and connecting hardware. Where similar jacks and plugs are used for both voice and data communication cabling, use a different color for jacks and plugs of each service.


E. 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/EIA!606!A.

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

3.7 FIELD QUALITY CONTROL

A. Perform the following tests and inspections:

1. Visually inspect UTP 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/EIA!568!B.1.

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.

a. Test instruments shall meet or exceed applicable requirements in TIA/EIA!568!B.2.

Perform tests with a tester that complies with performance requirements in "Test Instruments (Normative)" Annex, complying with measurement accuracy specified in "Measurement Accuracy (Informative)" Annex. Use only test cords and adapters that are qualified by test equipment manufacturer for channel or link test configuration.

5. UTP Performance Tests:

a. Test for each outlet and MUTOA. Perform the following tests according to TIA/EIA!568!B.1

and TIA/EIA!568!B.2:

1) Wire map. 2) Length (physical vs. electrical, and length requirements). 3) Insertion loss. 4) Near!end crosstalk (NEXT) loss. 5) Power sum near!end crosstalk (PSNEXT) loss. 6) Equal!level far!end crosstalk (ELFEXT). 7) Power sum equal!level far!end crosstalk (PSELFEXT). 8) Return loss. 9) Propagation delay. 10) Delay skew.

6. Final Verification Tests: Perform verification tests for UTP systems after the complete

communications cabling and workstation outlet/connectors are installed.

a. Voice Tests: These tests assume that dial tone service has been installed. Connect to the network interface device at the demarcation point. Go off!hook and listen and receive a dial tone. If a test number is available, make and receive a local, long distance, and digital subscription line telephone call.

b. Data Tests: These tests assume the Information Technology Staff has a network installed and is available to assist with testing. Connect to the network interface device at the demarcation point. Log onto the network to ensure proper connection to the network.


B. Document data for each measurement. Data for submittals shall be printed in a summary report that is formatted similar to Table 10.1 in BICSI TDMM, or transferred from the instrument to the computer, saved as text files, and printed and submitted.

C. End!to!end cabling will be considered defective if it does not pass tests and inspections.

D. Tests and Inspections:

1. Inspection: Verify that units and controls are properly installed, connected, and labeled, and that

interconnecting wires and terminals are identified.

2. Pretesting: Align and adjust system and pretest components, wiring, and functions to verify that they comply with specified requirements. Conduct tests at varying lighting levels, including day and night scenes as applicable. Prepare video!surveillance equipment for acceptance and operational testing as follows:

a. Verify operation of auto!iris lenses. b. Set back!focus of fixed focal length lenses. At focus set to infinity, simulate nighttime

lighting conditions by using a dark glass filter of a density that produces a clear image. Adjust until image is in focus with and without the filter.

c. Set back!focus of zoom lenses. At focus set to infinity, simulate nighttime lighting conditions by using a dark glass filter of a density that produces a clear image. Additionally, set zoom to full wide angle and aim camera at an object 50 to 75 feet away. Adjust until image is in focus from full wide angle to full telephoto, with the filter in place.

d. Set and name all preset positions; consult Owner's personnel. e. Set sensitivity of motion detection. f. Connect and verify responses to alarms. g. Verify operation of control!station equipment.

3. Test Schedule: Schedule tests after pretesting has been successfully completed and system has

been in normal functional operation for at least 14 days. Provide a minimum of 10 days' notice of test schedule.

4. Operational Tests: Perform operational system tests to verify that system complies with Specifications. Include all modes of system operation.

E. Video surveillance system will be considered defective if it does not pass tests and inspections.

F. Prepare test and inspection reports.

3.8 DEMONSTRATION
