DESCRIPTION OF SYSTEM <br /> <br /> (Trilon ShotSpotter - Gunshot Location System) <br /> <br /> The Trilon ShotSpotter System (the "System") is intended to be used to <br />provide law enforcement authorities with a means of rapidly locating the source <br />of gunfire in urban environments. The System consists of eight (8) acoustic <br />sensors mounted in strategic locations within a defined area in an elevated <br />position, usually 12 to 25 feet above the ground, typically on rooftops. The <br />sensors are networked via telephone lines to the central computer system in a <br />designated location by the law enforcement authority. As the system being <br />purchased is one that was originally tested by the City, the location of the central <br />computer system will remain the same as will the majority, if not all, of the <br />acoustic sensors. The Gunshot Location System is comprised of the following <br />components: <br /> <br /> Acoustic Sensors. Sensors consist of a microphone and preamplifier <br /> located in a weather resistant enclosure. This assembly, usually installed on a <br /> rooftop, is connected to a power supply and a telephone answering unit located <br /> in a protected area, usually indoors and in close proximity to the acoustic sensor. <br /> The sensors operate on a 110 volt power and are connected to a telephone line. <br /> <br /> Collector. The collector is an electronic unit located at the monitoring <br /> station, it accepts eight (8) telephone line inputs via modular connectors, and <br /> connects to the central computer system and annunciator in the dispatch room. <br /> <br /> Agmt-079 <br /> Shared/Redwood/Council <br /> FXS:rg <br /> 07/21/97 <br /> A-1 <br /> <br /> EXHIBIT "A" <br /> <br /> <br />
