Installation Instructions

Attaching the Door and Window Sensors

  1. Make sure to use the adhesive tape included with your sensor.
  2. Clean the surface of the door/window and frame with rubbing alcohol before placing.
  3. Check the alignment of the sensor and magnet so they are not hitting each other or an object when the door/window opens or closes.

Troubleshooting Common Problems with the Door and Window Sensors

My door and/or window sensor shows open, even when the door or window is closed.

  • 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.
