center conductor of 18 AWG or larger polyethylene insulation, and a black
non-contaminating polyvinylchloride (PVC) jacket.
2.16.2
Low Voltage Control Wiring
Twisted pair low voltage control wiring to be used above ground or as
direct burial cable shall be provided as described in Section 16792A WIRE
LINE DATA TRANSMISSION SYSTEM. Plenum or riser cables shall be IEEE C2
CL2P certified.
2.16.3
Digital Data Interconnection Wiring
Interconnecting cables carrying digital data between equipment located at
the security center or at a secondary control/monitoring site shall be not

PREDELIVERY TESTING
2.17.1
General
The Contractor shall assemble the test CCTV system as specified, and
perform tests to demonstrate that the performance of the system complies
with the contract requirements in accordance with the approved predelivery
test procedures. The tests shall take place during regular daytime working
hours on weekdays. Model numbers of equipment tested shall be identical to
those to be delivered to the site. Original copies of all data produced
during predelivery testing, including results of each test procedure, shall
be delivered to the Government at the conclusion of predelivery testing
prior to Government approval of the test. The test report shall be
arranged so that all commands, stimuli, and responses are correlated to
allow logical interpretation.
2.17.2
Test Setup
The Contractor shall provide the equipment needed for the test setup and
shall configure it to provide alarm actuated camera call-up and alarm
recording as required to emulate the installed system. The test setup
shall consist of at least 4 complete camera circuits. The alarm signal
input to the CCTV test setup shall be by the same method that is used in
the installed system. The video switcher shall be capable of switching any
camera to any monitor and any combination of cameras to any combination of
monitors. The minimum test setup shall include:
a.
Four video cameras and lenses, including dome cameras if required
for the installed system.
