Product Features & Benefits

The range includes the PD160 single channel detector and the PD260 dual channel detector.

The ease of installation of this product is not only cost effective but a pleasure to operate when determining the optimal parameters using quick and easy-to-use on-board diagnostics.

Automatic frequency selection makes the avoidance of cross-talk quick and simple.


  • Automatic Frequency Selection (AFS) - automatically selects the best frequency setting
  • Diagnostic capabilities - enable accurate diagnosis of loop and installation problems without the need for additional equipment
  • Completely configurable relay functions using LCD menu
  • Selectable permanent presence - eliminating premature barrier / gate / door closure
  • Loop isolation protection and reduced interference
  • Loop frequency indication – enables fast identification and elimination of cross-talk
  • Automatic Sensitivity Boost (ASB) - facilitates the reliable detection of all vehicle combinations and high-bed vehicles
  • Detect filter – screens out unwanted inputs
  • Powerfail memory - retains the presence of the vehicle when power is restored
