DESCRIPTION
The Opticom 792 Emitter is a compact, lightweight, weather-resistant encoded signal device intended for use on priority and probe frequency vehicles.
The Opticom 792 Emitter consists of a flashtube/reflector and housing assembly with an integral power supply and the required cables. The Opticom 792 Emitter converts 12 VDC vehicle battery power to the high voltage required for operation of the unit.
Accessory switch devices are also available. The operation of the device may be customized through its interface software.
The encoded signal pattern (composed of the individual vehicle class code and vehicle identification number) generated by the Opticom 792 Emitter is determined after installation through the use of interface software.
The Opticom 792 Emitter, when installed on authorized service and maintenance vehicles, may also be configured to utilize the automated range-setting feature of Opticom 700 Series Phase Selectors and Opticom™ 450 Series Discriminators. This feature refines and simplifies individual intersection setup and maintenance techniques.
The Opticom 792 Emitter separates precisely timed pulses of high-intensity light in the infrared and visible wavelengths at the base flash rate of approximately 10, 12 or 14 Hz. It also interleaves programmed encoded pulses that carry the vehicle class and ID number information. These energy pulses are sensed and processed by other Opticom Infrared System components to cause activation of the system.
