ST-9365 RF / Optical Priority Detector

The ST-9365 Priority Detector is a dual-card, two or four channel device to be used for encoded or non-encoded optical priority requests from all major brands of optical emitters, as well as EMTRAC 900 MHz FHSS radio.

Description

The Priority Detector responds to frequencies from all major optical emitter brands, and it recognizes the frequency rates of requesting vehicles to differentiate their priority levels. The Priority Detector is capable of receiving both optical and RF requests and prioritizing them by priority level and class of vehicle.

The Priority Detector is compatible with all major NEMA and 170-type cabinets. It can be installed directly into the input file of Type 170 controller cabinets or may be provided with a Priority Detector Case (ST-9194) for NEMA cabinets (when input-file space is not available).
