A roof smoke extraction fan with a stainless steel hood and red-lit transparent housing reveals its motor inside, set before the Helios "#FIREPROOF" panel reading "Immer da, wenn's darauf ankommt!". The panel covers mechanical smoke extraction and car park ventilation, and a ceiling unit hangs from a red frame above.
