The solution chosen, SHEVTEC® Extended Travel Distance system uses a dual smoke shaft and fan ventilated solution linked by smoke sensors through SE Controls’ powerful OSLoop® control system, which when triggered determines which shaft is closest to the fire and opens the smoke shaft doors on each floor to extract smoke away from escape routes, corridors and stairs. Once actuated, OSLoop continues to monitor the entire system throughout the incident to ensure the system maintains its performance in accordance with the imminent EN12101 part 9 standard.
