Opticom <br />Priority Control System <br />Infrared Emitter Model 492 <br /> <br />Description <br /> <br />The 3MTM OpticomTM Priority Control System Model <br />492 Emitter is a compact, lightweight, weather <br />resistant encoded signal device intended for use <br />on priority vehicles. The emitter is comprised of <br />a flash-tube/reflector and housing assembly with an <br />integral power supply and the required cables. The <br />emitter converts 12 Volt DC vehicle battery power <br />to the high voltage required for operation of the unit. <br />Accessory switch devices are also available. <br /> <br />The encoded signal pattern (comprised of the <br />individual vehicle class code) generated by the <br />emitter is established prior to ordering the emitter <br />and is specified at the time of procurement. <br />Vehicle class selection is customized during the <br />manufacturing process. <br /> <br />The emitter generates precisely timed pulses of high <br />intensity light in the infrared and visible wavelengths <br />at the base flash rate of approximately 10 or 14 Hz. <br />It also interleaves programmed encoded pulses that <br />carry the vehicle class information. These energy <br />pulses are sensed and processed by other Opticom <br />system components to cause activation of the system. <br /> <br />-- Model 492 <br /> <br />Description of Models <br /> <br />492H Emitter - a Command (high) priority emitter <br />492L Emitter - an Advantage (Iow) priority emitter <br /> <br />492T Emitter - an Advantage (Iow) priority <br />emitter, equipped with a visible light filter <br /> <br /> <br />
