Safety Entrapment Protection: 

  • NEMA4X photo eye sensors mounted to the guides 6” above the finished floor that project an IR beam across the width of the door. The breaking or interruption of the beam while the door is in motion will immediately stop downward travel and reverse the door to re-open to the top limit. 
  • Redi-Reverse Light Curtain consists of a 6’0” high light curtain integral to the guides. If an object passes through the light curtain during downward travel, the door will reverse to the open direction and come to rest upon reaching the open limit.
