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.

- 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 on board 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 125ms +/- 25ms (optional 250ms ± 30ms) is provided on vehicle entry. If the vehicle remains in the loop, a maximum of 3 seconds pulse paralysis time is provided before additional vehicles are detected.
- Frequency:
- F1F2 mode: 80 to 2400 μH nominal
- F0F2 mode: 50 to 1700 μH nominal
- FIF0 mode: 30 to 1200 μH nominal
- F0F0 mode: 20 to 700 μH nominal
- Sensitivity: Seven levels of sensitivity can be selected by 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%
- 3 1+2+0 = 0.16%
- 2 0+2+0 = 0.32%
- 1 1+0+0 = 0.64%
- 0 0+0+0 = Channel Off
- Other available detection products: These other detection products are also available from Oriux: 222N P/N 82-2039-01
