Troubleshooting

Detector does not see vehicles

  • Check loop resistance and megger the loop to ground.
  • Check that the lead-in is twisted and the splice is sealed.

Random detects

  • Seal the slot so the wires cannot move.
  • Keep loops at least 3 ft from other loops and moving metal.

Common questions
