Technical Appendix Specifications for the RADIO SYSTEM UPGRADE

I. Significant inter-cabling, whether RF, AC, AUDIO or CONTROL cables and/or wiring, shallbe labeled with pre-printed adhesive wire markers. Markers shall be placed at each end,adjacent to the connector, plug or terminus. This data shall be recorded and match that in theinstallation documentation.J. All equipment cables or cable bundles, to the greatest extent feasible, will be neatly tied bymeans of plastic tie wraps and secured by clamps to flat surfaces.K. All cable/wiring bundles exiting the equipment must do so through the top of the cabinets.Rubber grommets or other suitable protection shall be used at cabinet knockouts to protectthe cable/wiring. Splicing of AC, AUDIO or CONTROL cable/wiring will not be permitted.L. With the doors closed, all equipment cabinets shall present a sealed enclosure to minimize theentry of insects and to prevent entry of birds and rodents.M. All equipment operating from AC power, including radio controls, central electronics,repeaters, remote receivers, control stations, controllers, and computer terminals, shall beequipped with surge protection devices. All outlet strips and surge protection shall be rackmounted.N. Lightning suppression devices shall be provided for power input circuits, control circuits,telephone lines, antenna transmission cables, and all other circuits, equipment, and cablingthat could be exposed to lightning-generated transients. Surge protection devices shall berated for maximum surge suppression and noise suppression as appropriate to the protecteddevice, and the Contractor's equipment and design.O. Lightning suppression devices shall be rated for maximum surge current, turn-on voltage,turn-on time, power capacity, and other characteristics as appropriate to the protected circuit,and the Contractor's equipment and design. Lightning suppression devices shall be connectedto earth ground with insulated wire appropriate to the application. The following are generalrequirements:P. Maximum surge current shall be 20,000 A, based on the IEEE 8-microsecond rise-time/20-microsecond decay-time waveform.Q. The turn-on voltage shall be no less than 600 VDC.R. The turn-on time shall be no more than seven nanoseconds after voltage attains the 600 VDCturn-on level.S. The device shall be capable of passing up to 600 microJoules of energy.T. High-current spike suppression shall be capable of 15,000 A, based on the IEEE 8-microsecond rise-time/ 20-microsecond decay-time waveform.U. High frequency noise suppression shall be:1. -Greater than 20 dB at 1 MHz2. -Greater than 35 dB at 10 MHzMobile InstallationsA. The Contractor shall coordinate with the City to establish a work area, other necessaryfacilities for mobile equipment installations, vehicle availability, and detailed schedule.City of San Luis Obispo 77 Radio System Upgrade TECHNICAL APPENDIX
