The model OSPOCx family Optical Signal Processor (OSP) is the first OSP offered by TOMAR that receives and decodes *GTT OPTICOM-brand coded emitter signals.  Installed inside the traffic cabinet, the OSPOCx family provides power for Tomar DETOCxx and/or GTT OPTICOM 7xx Optical Detectors, receives, decodes and prioritizes signals from the detectors, logs preemption and priority control activity, communicates with other traffic control devices, and optically isolates the preemption channels.

The OSPOCx family is delivered default programmed to respond on a first-come, first-served basis to optical signals from vehicles within two signal bands.  Emergency band signals are typically emitted by emergency vehicles to effect a preemption of normal traffic control timing and are given the highest priority to allow rapid emergency response with enhanced safety.  Transit band signals are generally emitted by transit or other non-emergency municipal vehicles to effect a priority change for the vehicle’s approach direction without necessarily interrupting traffic control timing.  Classes 0-9 and codes 0-999 in each class can be individually identified in each band.

Using a simple Windows-based configuration program, the user can define up to 10 additional classes within each signal band with different priorities, detection ranges, and choices of actions, from simple logging to full traffic preemption.

Equipped with an Ethernet port and the ability to classify and announce the presence of multiple vehicles in real-time, the OSPOCx family makes an excellent intelligent vehicle sensor for ITS applications.

The OSPOCx family OSP is compatible with NEMA TS-1, TS-2, and CA/NY 170, and 2070 controllers and meets all NEMA and CalTrans environmental requirements. The OSPOCx family plugs directly into a 170 input file without any additional hardware and does not use the internal 24VDC cabinet power. For NEMA cabinets without prewired preemption slots, the TOMAR model 1881 rack provides the necessary hardware and harnessing to allow simple connection to detector outputs and controller inputs.


Plug-and-Play Firmware allows the ability to add accessories in the field without manual configuration.  This allows you to buy only what is needed today and add more capability later, saving precious funds.

Active Reflection Suppression prevents cross street preemption due to reflected emitter technology.  Only TOMAR’s advanced, digital signal processing can eliminate this troublesome side effect making system installation and setup far less critical.

Expansion Port provides easy connection of the OSPOCx family to other accessory modules like green phase monitors, confirmation light drivers, and external preemption.
