In the event of detection the SHEVTEC Smoke Control Dampers activate on the affected floor in conjunction with the top of shaft and top of stair AOVs to provide a flow of smoke exhaust to atmosphere. All dampers on the remaining floors will remain closed and must be locked out to reduce smoke leakage and the risk of the fire spreading to additional floors.
