<br />ATTACHMENT "A" <br /> <br />CITY OF SANTA ANA PUBLIC SAFETY RADIO SYSTEM COVERAGE <br />SPECIFICATIONS <br /> <br />1. Performance. <br /> <br />Specifications are provided to assist property owners in satisfying a delivered audio <br />quality (DAQ) of 3 with a 90% reliability factor for emergency personnel using radio <br />communication in their buildings and structures. Property owners who can demonstrate <br />full compliance with the reliability factor without adhering to all of the following <br />specifications may be excused from all or part of these provisions. Property owners who <br />adhere to all of the specifications and fail to reach the reliability factor must employ all <br />resources necessary to ensure full compliance. Performance and compliance will be <br />inspected annually as part of the Santa Ana Fire Department's Annual Fire Inspection. <br /> <br />2. Signal Strength, Signal Rejection, Modulation Compatibility, Delivered <br />Audio Quality and Technical Specifications. <br /> <br />The following defines the minimum required level of radio signal strength: <br /> <br />. A minimum signal strength of (-95dBm) in 90% of the area of each floor of the <br />building from both the 800 MHz Countywide Communications Systems and <br />from within the building is required. <br /> <br />. The frequency range supported from the 800 MHz Countywide <br />Communications System shall be 851 - 869 MHz (base transmitter <br />frequencies ). <br /> <br />. The frequency range supported to the 800 MHz Countywide Communications <br />System shall be 806 - 824 MHz (radio field transmit frequencies). <br /> <br />. A public safety radio amplification system shall include filters to reject <br />frequencies below 851 MHz and frequencies above 869 MHz by a minimum <br />of 35 dB. <br /> <br />. All system components must be 100% compatible with analog and digital <br />modulations after installation without additional adjustments or modifications. <br />The systems must be capable of encompassing the frequencies stated herein <br />and capable of future modifications to a frequency range subsequently <br />established by the City of Santa Ana. If the system is not capable of <br />modification to future frequencies, then a new system will need to be installed <br />to accommodate the new frequency band. <br /> <br />. Active devices shall have a minimum of -50 dB 3rd order intermodulation <br />protection. <br /> <br />50A-7 <br />
