3M Opticom 792 Emitter

If anyone is tossing and turning at night trying to figure out what to get me for my birthday (in September.. heh), here’s an excellent idea. An infrared emitter for emergency vehicles that will turn traffic lights green for you (that of course is a joke, I’m sure you can’t buy one… but it would be neat).

The 3Mâ„¢ Opticomâ„¢ Priority Control System Model 792 Emitter is a compact, lightweight, weather resistant encoded signal device intended for use on priority and probe vehicles. The emitter is comprised of a flash-tube/reflector and housing assembly with an integral power supply and the required cables. Available models include: the Model 792H emitter – a high priority emitter; the Model 792L emitter – a low priority emitter; the 792T emitter – a low priority emitter equipped with a visible light filter; the Model 793R emitter – a range setting emitter for high priority, low priority, or probe frequency; the Model 792P emitter – a probe frequency emitter. The emitter converts 12 Volt DC 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 (comprised of the individual vehicle class code and vehicle identification number) generated by the emitter is determined after installation through the use of interface software. The emitter, when installed on authorized service and maintenance vehicles, may also be configured to utilize the Automated Signal Intensity Threshold setting feature of Series 700 Phase Selectors and Series 250/450 Discriminators. This feature refines and simplifies individual intersection setup and maintenance techniques. The 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 system components to cause activation of the system. Model 792 emitters are programmed using the Model 790IS Emitter Software Kit.

  3. These units are available on ebay all the time! In fact there are two for sale right now! You can also acquire them by watching your local state auction site or DOT auction location. These units are not difficult to install and work using standard battery power.
