N205AU OVERHEAD DOOR SWITCH WITH UNIVERSAL MAGNET INSTALLATION INSTRUCTIONS, continued TOP MOUNT: • With the overhead door closed, position the magnet at the top of the door in the desired location, then align the switch under the magnet. Adjust the position of the switch and magnet to ensure there is adequate clearance between the housings (1/4” minimum). • Make sure the stainless steel armored cable will not interfere with the door operation.
