Opticom Infrared System - Signal Control

1 October 2007 Opticom Infrared System Matched Component Products DescriptionThe Opticom Model 752E Phase Selector is aplug-in, two-channel, dual-priority, encodedsignal device designed for use with Opticom Infrared System Emitters and Detectors. TheOpticom Model 754E Phase Selector is aplug-in, four-channel, dual-priority, encodedsignal device designed for use with Opticomemitters and detectors. Both meet CErequirements. Opticom models 752E and 754 Eare powered by an external 24 VDC powersupply and contain their own internal powersupply to support Opticom detectors.

2 Opticom Model 760E Card Rack is Model 739 Detector Cable isrequired to connect either Opticom phaseselector to any Opticom detector. Opticom models 752E and 754E recognize anddiscriminate among three distinct Opticomemitter frequency rates via Opticomdetectors: high priority, low priority andprobe frequency. Within each of these threefrequency rates, the Opticom phase selectorsfurther discriminate among 10 classes ofvehicle identification codes, with 1,000individual vehicle codes per class 10,000total per frequency rate. Opticom models 752E and 754E internallyrecord each activation of the System .

3 Eachentry contains the: Intersection name Date and time of the activity Vehicle class code of the activating vehicle Activating vehicle s ID number Channel called Priority of the activity Final green Signal indications displayed atthe end of the call Time spent in the final greens Duration of the activationOpticom Model 752E Phase Selector (left) and Opticom Model 754E Phase Selector (right) Opticom Infrared SystemOpticom Models 752E and 754E Phase Selectors Opticom Models 752E and 754E PhaseSelectors also include RS232 interfacecapability to communicate with computers orcontrollers.

4 Optional interface software isavailable for System setup and primary Opticom Detector inputs andpower outputs are on the card edgeconnector. Two additional auxiliary detectorinputs are available for each channel througha front panel connector. The connector alsocontains Signal indication sensing channel delivers a constant output for high-priority activation and a pulsedoutput for low-priority activation. A high-priority Signal received on any channel willoverride any low-priority probe frequency does not place a call request to the Signal controller.
