  The N505AU Universal Track Mount switch and magnet system can be installed on either the right or left side of the overhead door. To
  change the direction of the direction of the armored cable, remove the 2 screws attaching the switch to the bracket and flip the switch. Insert
  and re-tighten the screws.
  Depending on the type of Roller Guide Track your door has, or operating condition of the door, it may be necessary to remove the rear half of
  the switch bracket to complete installation.
  • Un-pack the switch and magnet assemblies and set aside the magnet bracket assembly.
  • Slide the two halves of the switch bracket assembly apart so they are fully extended against the clamping screw.
  • Position the switch bracket assembly on the guide roller track in the desired location. Make sure the rear half of the bracket assembly is fully extended around the track.
  • Slide the bracket halves together on the track and hold the switch assembly in position. Carefully open and close the door to make sure the door will operate freely without contacting the switch or bracket assembly. ( If there is interference between the lower guide
  roller bracket plate and the switch bracket assembly, use the alternate mounting method below.)
  • Secure the switch and bracket assembly to the track by tightening the clamping screw on the side of the bracket.
  • With the door closed, align the magnet bracket assembly with the switch. Make sure there is sufficient clearance between the magnet and switch so the door can open and close freely.
  • Attach the magnet to the door using #6 self-tapping screws.
  • Connect an ohm meter to the switch leads and open and close the door to test switch for correct operation.
  • Connect the switch leads to the alarm system.
