Infrared Light Curtains

These are IR light curtains used on lift doors to prevent people and objects becoming trapped in the doors. They have their own controller that is connected to the lift logic controller. If the beam is broken, the door will reopen or stay open. **** Please Note - This video is for educational and interest purposes only. Lift shafts and motor rooms are places that require extra care. Please do not put yourself at risk and always be respectful to people and property ****
