Closure prevention for 120 s


Optická závora


The fire shutter can be equipped with a closing edge protection (optical barrier). It is used to prevent the closing of the fire shutter in case of an obstacle located in the path of the fire shutter. In the event of a fire alarm, according to  the CE standard, it is not possible to interrupt the closing of the fire shutter in any other way than by an optical barrier, for a maximum of 120 s.

Additional equipment of the AVAPS fire shutter.


  • Supplied with cable
  • The optical barrier draws attention, for example, to the occurrence of an obstacle in the path of the conveyor system, signaling and communication with the control unit of the conveyor system causes the obstacle to shift and subsequently close the fire dividing structure
