8-Series Slimline Dual Channel Parking Detector

8-Series Slimline Dual Channel Parking Detector

'Quick and Simple Install DIN-Rail Mount with Wi-Fi Setup'

The 8 series, Nortech’s new flagship Parking Vehicle Detector addresses the market’s need for a slimline, advanced vehicle detection solution. Our Automatic Frequency Selection (AFS) algorithms introduced in the 7 series detectors have been refined and optimised resulting in simplified setup and installation of complex multi-lane access control sites.

Product Features & Benefits

The new DU800 wireless diagnostic unit allows for detector configuration and installation feedback of 8 series detectors on any iOS or Android device. This eliminates the need to adjust any mechanical interfaces once the unit has been installed.

The new slimline, DIN Rail mount housing allows for more physical connections than the traditional relay base and Nortech’s innovative modular design allows for future expansion.

Like its forebears, the 8 series detectors simply work, offering peace of mind in even the most complex installation.

The PD280 supports two loops.


  • Slimline - Can be installed in even the most physically constrained environments
  • Expandable - The innovative expansion port on the PD180 allows for the addition of modules to the system
  • AFS - Automatic Frequency Selection (AFS) sets the optimal operating frequency to ensure minimal interference and maximum reliability
  • PowerFail Memory - In the event of a power failure, the PD180 will retain the presence of the vehicle when power is restored
  • Diagnostics - Comprehensive, wireless diagnostics allow for accurate diagnosis of loop and installation problems as well as configuration adjustments to eliminate issues using Nortech’s DU800 and Integr8 App
