SYSTEM DESCRIPTION
1.2.1
General
**************************************************************************
NOTE: Show installation details on drawings. Add
requirements for additional site specific conditions
such as furniture/equipment layout within protected
areas, and hazard location area, type of hazard,
class, and group.
**************************************************************************
The Contractor shall configure the system as described and shown. All
television equipment shall conform to EIA 170 specifications. The system
shall include all connectors, adapters, and terminators necessary to
interconnect all equipment. The Contractor shall also supply all cabling
necessary to interconnect the closed circuit television (CCTV) equipment
installed in the Security Center, and interconnect equipment installed at
remote control/monitoring stations. If the CCTV system is installed for
use with an Electronic Security System (ESS) the Contractor shall interface
the CCTV system with the ESS.
1.2.2
System Overall Reliability Requirement
The system, including all components and appurtenances, shall be configured
and installed to yield a mean time between failure (MTBF) of at least
10,000 hours, and shall be calculated based on the configuration specified
in paragraph "System Overall Reliability Calculations."
1.2.3
Power Line Surge Protection
All equipment connected to AC power shall be protected from surges.
Equipment protection shall withstand surge test waveforms described in IEEE
C62.41. Fuses shall not be used for surge protection.
1.2.4
Video and Sync Signal Transmission Line Surge Protection
All cable, except fiber optic cable, used for sync or video signal
transmission shall include protective devices to safeguard the CCTV
equipment against surges. The surge suppression device shall not attenuate
or reduce the video or sync signal under normal conditions. The surge
suppression device shall be capable of dissipating not less than 1500 watts
for 1 millisecond, and the response time from zero volts to clamping shall
not be greater than 5 nanoseconds. Fuses shall not be used for surge
protection.
1.2.5
Control Line Surge Protection
All cables and conductors, except fiber optic cables, which serve as
communication, control, or signal lines shall be protected against surges
and shall have surge protection installed at each end. Protection shall be
furnished at the equipment and additional triple electrode gas surge
protectors rated for the application on each wireline circuit shall be
installed within 1 m 3 feet of the building cable entrance. Fuses shall
not be used for surge protection. The inputs and outputs shall be tested
in both normal mode and common mode using the following waveforms:
a.
A 10 microsecond rise time by 1000 microsecond pulse width
waveform with a peak voltage of 1500 volts and a peak current of
