DESCRIPTION
The Opticom 794M Multimode LED Emitter is a compact, lightweight, weather-resistant encoded signal device intended for use on priority vehicles.
When used in vehicles equipped with both Opticom infrared (IR) and Opticom GPS, the 794M Multimode LED Emitter eliminates the need to have a separate IR emitter and radio/GPS antenna modules on the roof of the vehicle. The Opticom GPS radio/GPS unit and vehicle control unit are still required for Opticom GPS operation.
The Opticom 794M consists of an IR LED array with an integral power supply, integrated radio and GPS antennas for use with Opticom GPS vehicle equipment and the required cables. Accessory switch devices are also available for controlling the
IR emitter. The operation of the IR emitter may be customized through its interface software or remote coding unit.
The IR encoded signal pattern (composed of the individual vehicle class code and vehicle identification number) generated by the Opticom 794M is programmed through the use of interface software or remote coding unit.
The Opticom 794M IR emitter emits precisely-timed pulses of infrared light at the base flash rate of approximately 10 or 14 Hz. It also interleaves programmed encoded pulses that carry the vehicle class and ID number information. These infrared
pulses are sensed and processed by other Opticom IR system components to activate the system.
The Opticom 794M is capable of being programmed via the RC790 remote coding unit, eliminating any dependency on a computer. By simply pointing the RC790 at the Opticom 794M, the user can set vehicle class and ID, visible LED, disable mode, restore factory default settings and initiate diagnostics with just a few pushes of a button.
