222 GP8 & 224 GP8
Oriux’s GP8 detectors allow you to optimize performance parameters for the most demanding intersection control applications.
For any application, the Oriux GP8 detectors identify loop events such as open loops, shorted loops, or loops with excessive inductance changes. The event LED, using special flash rates, indicates the condition of the loop fault, whether present or historical. This is standard operation for intersection control, where reliability is a key concern.
Designed specifically for intersection control, where crosstalk must be eliminated, the Oriux GP8 detectors provide four front-panel selectable frequencies. Additionally, the GP8 detectors function as scanning detectors, further reducing the possibility of crosstalk between two loops connected to the same detector.

Optimized Performance for Intersection Control
Oriux’s designs the GP8 detectors to optimize performance parameters and meet the demands of intersection control applications. They are engineered to reliably detect loop events such as open loops, shorted loops, or loops with excessive inductance changes, ensuring high reliability where it matters most. It offers excellent noise filtering to ensure accurate vehicle detection even in challenging environments.Loop Fault Detection and Indicators
The detectors feature an event LED that uses special flash rates to indicate the status of loop faults—whether currently present or historical. In addition, this clear fault indication supports quick diagnostics and maintenance, vital for maintaining uninterrupted intersection operations.Crosstalk Elimination and Frequency Selection
Specifically designed to eliminate crosstalk between loops, the GP8 detectors offer four different front panel selectable frequencies. Additionally, they operate as scanning detectors, further minimizing interference between loops connected to the same unit. This ensures clean and accurate detection even in complex intersection setups.Fast and Consistent Response for Advanced Applications
With fast, predictable, and consistent response times, the GP8 detectors facilitate precise speed and occupancy measurements. This capability is critical for Intelligent Vehicle Highway Systems (IVHS) and other advanced traffic management applications.Easy Setup and User-Friendly Controls
Setup is straightforward with front panel switches for frequency, sensitivity, and operating mode. Users can simply connect the unit, as well as adjust settings as needed, and the detector is ready to operate—making installation and maintenance quick and hassle-free.Detection Modes and Sensitivity
Each channel can be configured to operate in either pulse or presence mode, depending on the specific needs of the application. The sensitivity boost function helps maintain the detection of both small and high vehicles, enhancing performance across vehicle types. The loops are scanned sequentially, further enhancing detection accuracy and reducing potential signal conflicts.Easy Installation and Setup
Designed for quick and simple setup, the GP8 detector allows for fast deployment and minimal maintenance, thus making it a reliable choice for busy traffic environments.TECHNICAL DETAILS
- Operating Modes: Two modes of operation are available via a mode selection switch, Pulse (PLS) and Presence (PR).
- Presence: Presence times of 16, 60,120 minutes, or permanent are available by setting the onboard switch.
- Optional: Any presence time value can be set from 1 to 127 minutes in 1-second increments.
- Pulse: In pulse mode, a momentary output of 125ms +/- 25ms (optional 250ms ± 30ms) is provided on vehicle entry. If the vehicle remains in the loop, a maximum of 3 seconds of pulse paralysis time is provided before additional vehicles are detected.

- F0F0 mode: 20 to 700 μH nominal
- Sensitivity: Seven levels of sensitivity can be selected by the DIP switch as follows:
- 7 1+2-+4 = 0.01%
- 6 0+2-+4 = 0.02%
- 5 1+0-+4 = 0.04%
- 4 0+0-+4 = 0.08%
