SAFETY ENTRAPMENT PROTECTION 
Option: Photo Safety Sensors mounted to the guides 6” above the finished floor directing a beam across the opening which will stop the door and reverse to the fully open position if broken while door is cycling to close.
Option: Redi-Reverse Light Curtain consists of a 6’0” high light curtain integral to the guides, left and right. If an object passes through the light curtain during the close cycle, the door will reverse to the open cycle and come to rest upon reaching the open limit.
Option: NEMA 4X (weather resistant) photo safety sensors mounted to the guides 6” above the finished floor that project an infrared beam across the width of the door. Breaking the beam while the door is in motion will result in the immediate stop of downward travel and reverse the door to reopen to the top limit.
Option: Electric Monitored Sensing edge with a coil cord or take up reel, or a wireless monitored transmitter and receiver type monitored sensing edge

These are the operator options for Alpine’s Red-Storm® security door. Please see our entire line of service door operators.
