All Other LocationsOther control stations shall utilize DB436 and DB230 model antennas.Cable losses shall not exceed 37% of transmitter power. In-line TVSS unit shall be provided.Transmitter Combiners – Control StationsUHF stations at Fire Station 1 shall utilize three, four-port dbSpectra DBS-HC114 control stationcombiner units. Receive ports on each combiner shall connect to a master 8-port UHF multicouplerequipped with parallel bandpass filters tuned for 453-454 and 460-463 MHz passbands. Themulticoupler shall also directly connect to a 463 MHz MEDCOM receiver. The remaining fourports shall be spare. Transmit ports shall connect to separate antennas.VHF stations shall either connect to a four-port dbSpectra DBS-HC115 control station combiner unitwith receiver preamplifier, a hybrid combiner, a passive splitter, or a separate, dedicated antenna.There are various bandpass and notch filters that must be installed in some of the antenna lines.These are detailed in the previous table. Contractor shall verify the configuration and design of thecombiners. Contractors are responsible for proper design and operation.Control station combiner and filter placement is described in the previous table.Active control stations combiners shall be connected to backup power.City of San Luis Obispo 70 Radio System Upgrade TECHNICAL APPENDIX
Section 8. BACKUP POWER SYSTEMSThis section includes the requirements for backup power systems at remote sites. In general, all remotesites shall be equipped with DC battery float systems using modular rectifiers.Related Work by Other ContractorsThe City shall supply UPS and generator power to all equipment at Fire Station 1, including theEquipment Room and the dispatch workstations. The contractor shall provide load, power dissipation(BTUH) and outlet requirement information to the City as soon as possible.The City shall also supply backup generator power to equipment at Fire Station 2, Fire Station 3, andSouth Hill.Any additional electrical work required shall be performed by the City.GeneralA. All essential site equipment shall be powered by a DC battery power supply furnished by theContractor. The system shall include batteries, battery racks, float-type battery rectifiers, DCload centers and rack distribution/fuse panels.B. 48 VDC systems are preferred unless a significant portion of equipment is not capable of thissupply voltage. All power systems shall utilize the same voltage.C. The contractor shall be responsible for connecting the radio system equipment to thecommercial, DC power plant and emergency generator at each site.Run TimesRun times are specified in the Wireless Systems Section.BatteriesA. Modular stationary batteries shall be sealed maintenance-free type with sufficient amperehourcapacity to provide for the minimum run times.B. Battery life expectancy shall be at least 10 years in normal float-type service. No ventingfacilities or special battery rooms shall be required for normal operating conditions.C. Battery racks shall be furnished with plastic rail covers to preclude corrosion of battery rack.The battery bank, and all motion stabilizing hardware required for seismic considerationsshall be assembled using appropriate corrosion-resistant hardware (e.g. lead plated intercellconnector straps, terminal lugs and bolts/nuts).Battery RectifiersA. Battery rectifiers shall provide sufficient current output to supply station load requirements(plus a 25 percent station load expansion) and simultaneous charging of a fully dischargedbattery bank to full capacity in 24 hours. Battery rectifiers shall employ a redundant, loadsharingdesign. The charger shall operate in ambient temperatures of 0ºC to +50ºC.B. The power plants shall be designed for mounting within a standard 19” or 23” wide relayrack. The contractor shall supply racks of sufficient vertical height and depth to safelyaccommodate the power plants and provide suitable ventilation for heat dissipation.City of San Luis Obispo 71 Radio System Upgrade TECHNICAL APPENDIX
