Why does my EMX Industries MVP D-TEK Security Sensors detector detect intermittently when no vehicle is on the loop?

  Thomas YoderJul 28, 2025
  Intermittent detection by your EMX Industries Security Sensors, even when no vehicle is present, can stem from several causes: * A faulty loop. * Poorly crimped or loose connections. * Cross-talk between multiple loop detectors. * The loop not being securely installed, leading to movement within the pavement. To resolve this: 1. Perform a megger test from the loop lead to the ground, ensuring it exceeds 100 megaohms. 2. Inspect loop connections at the terminals. 3. Confirm splices are correctly soldered and moisture-sealed. 4. Set multiple loops to different frequencies. 5. Ensure the loop is securely installed in the pavement and that the site's condition prevents loop wire movement.

What to do if the red LED is constantly on (stuck in detection mode) on my EMX Industries MVP D-TEK?
- H
  Hannah MaysAug 3, 2025
  If the red LED on your EMX Industries Security Sensors is constantly illuminated, indicating it's stuck in detection mode, it could be due to a faulty loop or a poorly crimped/loose connection. To address this: * Perform a megger test from the loop lead to ground, ensuring the reading exceeds 100 megaohms. * Check the loop connections at the terminals. * Verify that all splices are properly soldered and sealed against moisture.

How to fix a fast flashing green LED on EMX Industries MVP D-TEK Security Sensors?
- V
  vsmithAug 8, 2025
  A fast flashing green LED on your EMX Industries Security Sensors indicates a shorted or disconnected loop wire. Here’s how to troubleshoot: * Check the loop resistance using a multimeter; it should read between 0.5 ohms and 5 ohms. If the reading falls outside this range, replace the loop. The reading should be steady. * Inspect loop connections to the terminals. * Momentarily flip the RESET switch down.

What does it mean if the green LED is slowly flashing on my EMX Industries MVP D-TEK?
- G
  grantwilliamAug 14, 2025
  A slow flashing green LED on your EMX Industries Security Sensors typically means the loop wire was previously shorted or open. To resolve this, check the loop resistance with a multimeter to ensure it reads between 0.5 ohms and 5 ohms. If the reading is outside this range, replace the loop, ensuring the reading is steady. Then, momentarily flip the RESET switch down.

How to troubleshoot a green LED that is not on for EMX Industries Security Sensors?
- K
  Kimberly GarciaAug 20, 2025
  If the green LED on your EMX Industries Security Sensors is not lit, the most likely cause is a lack of power. Check the power supplied to the MVP D-TEK on pins 1 (white wire) and 2 (black wire). The voltage should measure between 12-240 VDC/AC.
