Electronic devices are properly grounded.
Powered devices have AC power from the proper circuit and hot, neutral, and ground conductors are
connected correctly.
Insulation and shrink tubing are present where required.
Dust, debris, solder, splatter, etc. is removed.
Cable is dressed, routed, and labeled; connections are consistent with regard to polarity.
Grounding System Tests.
Measure and record the DC resistance between the technical ground in any equipment rack or
console and the main technical system ground. Resistance should be 0.1 ohms or less. Provide this
information in pre-commissioning report to Consultant.
When the technical grounding system is complete, the Contractor will be required to demonstrate that
this system is in no way bonded to the building safety grounding system except at the main service
entry panel. With the power to the central distribution panel removed, the Contractor will disconnect
the A/V system technical ground conductor from the main ground buss bar at the central distribution
panel. At this point, an open circuit greater than 1 megaohm should be measurable between the
technical ground and the building safety ground. The Contractor will measure and insure that the
utility ground and the technical ground are in no way bonded together. Provide this information in pre-
commissioning report to Consultant.
Cabling Tests.
Submit printed test reports proving the systems to be in full compliance to the consultant as part of
the pre-commissioning systems report.
After installation, and before termination, all wiring and cabling shall be checked and tested with a
megohmeter to ensure there are no grounds, opens, or shorts on any conductor or shields.
Verify all audio lines are wired to maintain proper continuity and polarity.
Perform TDR measurements on all triax and coax video cables.
Perform sweep tests on all triax and coax cables with a spectrum analyzer. When documenting the
results of these tests, include the calculated loss based on length of the video cable measured with
the TDR. Correct cabling for any field readings that differ more than 20% from the calculated loss.
Test all CAT5E cables to verify they meet full CAT5E specifications. Tests will use a certified tester
that will confirm bandwidth, cable distance, and error and bit rate detection.
Optical Fiber Cable Testing
Test all fiber optic cable strands for continuity and performance before and after the cables are
pulled and terminated.
Test link attenuation of all installed multimode fiber optic strands after splicing and termination
in accordance with ANSI/TIA/EIA-568-B.1, Section 11.3.
One direction with an optical light source and an optical power meter.
Test at two wavelengths to account for attenuation differences due to wavelength:
850 nm and 1300 nm for multimode strands
1310 nm and 1550 nm for singlemode strands
Test multimode strands in accordance with ANSI/EIA/TIA-526-14A, Method B, One
Reference Jumper.
For multimode strands, wrap reference jumper around mandrel to remove high-order mode
transient losses as specified in ANSI/TIA/EIA-568-B.1, Section 11.3.3, Table 11-15.
Test Singlemode strands in accordance with ANSI/EIA/TIA-526-7, Method A.1, One
Reference Jumper.
