Fire curtain with a loophole in the Solaris shopping center

We have made measurements and made individually sized fire curtains with fire resistance EI60 MVA (FireTechnics) in the shopping center Salaris. The curtain panel opens and closes automatically on a signal from the fire alarm panel. Separates the fire compartments from the spread of fire.
As can be seen in the video, a loophole door is provided in the canvas for the emergency evacuation of those who did not have time to leave the room. The loophole is marked in yellow and visible from afar.
