3140 with 1881 Card Cage |
The 3140 OSP is the most advanced of the 3000 Series. In addition to providing the advanced detection and discrimination capabilities of the standard 3000 Series OSPs, the 3140 is equipped with an event logging system. Installed inside the traffic cabinet, the 3140 provides power for the 209X Optical Detectors, receives and prioritizes signals from the detectors, and optically isolates the preemption channels.
The 3140 OSP 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 preempt 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 allowing a priority change for the vehicle’s approach direction without necessarily interrupting traffic control timing.With the optional eLock emitter authenticator system installed, up to 65,000 vehicles in each signal band can be individually identified.
The TOMAR 3140 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.
- Expansion Port provides easy connection of the 3140 to other accessory modules like the elock emitter authentication system, green phase monitors, confirmation light drivers, and external preemption adapters for controllers that do not have internal preemption software.
- Preemption channel disconnect switches allow the preemption outputs from the 3140 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 3140 OSP is compatible with NEMA TS-1, TS-2, and CA/NY 170 controllers and meets all NEMA and CalTrans environmental requirements. The 3140 plugs directly into a 170 input file without any additional hardware and does not use the internal 24VDC cabinet power. For NEMA cabinets without pre-wired preemption slots, the TOMAR model 1881 card cage provides the necessary hardware and harnessing to allow simple connection to detector outputs and controller inputs.
 1881 Card Cage and Wire Harness |
| The 1881 Card Cage provides all the necessary hardware and harnessing required to allow the simple wiring of the 3140 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. |
TRUE 10 YEAR WARRANTY!
Covers the 3140 OSP and all STROBECOM II components. Unlike other manufacturers, TOMAR’s 10-year warranty has NO fees or charges for warranty repairs after 5 years.
