mount tHe contact SenSor
We recommend you to mount the magnet unit on a door, window, or
medicine cabinet, and mount the sensor unit on its respective frame.
NOTES
• Make sure the mounting surface is clean. A textured surface or any
imperfections to a smooth surface can keep the mounting tape from
making a strong bond.
• Make sure you align the magnet unit with sensor unit when mounting.
The distance between the sensor unit and magnet unit must be less
•
than 1 cm (0.4 inch).
• The door images in this installation guide are for conceptual reference only.
TIPS
• If there is a difference in level between the door, window, or medicine
cabinet and its respective frame, or the frame is too narrow or has some
decorative molding, you can choose to mount the contact sensor with a
spacer. You can also mount the magnet unit on the frame, and the sensor
unit on the door, window, or medicine cabinet instead.
You can choose to mount the sensor unit with mounting tape irst, and
•
then use screws later if you decide to mount it at that location for long
term.
