In this video of the manufacturer EJ Germany you can see a test for the emergency, which hopefully will never come: In the event of a fire, 20 smoke vents will open in the sidewalk above the U6 platform, just outside the Westin Grand.

As you can see, the flaps indicate their opening with light and sound signals.
