Troubleshooting Common Problems with the Door and Window Sensors

  • Ensure the magnet is within half an inch of the sensor when closed. Use spacers that were included as necessary.
  • Ensure magnet and sensor align with the alignment arrows.  The “narrow” ends of the arrows on the magnet and sensor should be closest to each other.
  • Ensure magnet is installed parallel to the sensor, not perpendicular.
