Optical Preemption & Priority Control Systems 3080 OSP CARD AND CARD CAGE The 3080 Optical Signal Processor (OSP) is TOMAR’s mid-range OSP providing the advanced detection and discrimination of all 3000 Series OSP’s with improved system security and upgradability. Installed inside the traffic cabinet, the 3080 provides power for 209X Optical Detectors, receives and prioritizes signals from the detectors, and optically isolates the preemption channels. The 3080 responds 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. The 3080 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 3080 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. 3080 OSP The TOMAR 3080 Optical Signal Processor offers the following features and benefits: Modular construction allows tool-less field repair and firmware upgrades. Competitive products must be returned to the factory for proper repair. Plug-and-Play Firmware allows the ability to add preemption channels or other 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. Preemption channel disconnect switches allow the preemption outputs from the 3080 to be physically disconnected from the controller inputs during setup and testing. This allows traffic technicians the ability to perform all system setups and testing without disrupting traffic flow. The 1881 Card Cage provides all the necessary hardware and harnessing required to allow the simple wiring of the 3080 card to the detector outputs and controller inputs. The 1881 is equipped with two 60” long cables which are wired to the controller. The first cable carries all 115 VAC power wiring, safety ground, and card outputs. The second cable is terminated to a 12 point terminal block which is typically mounted in the wiring compartment of the cabinet. The detectors are then connected to the terminal block. 2 TOMAR Electronics, Inc. 2100 W.
