This chapter proposes three different design options to achieve the smoke management system objectives in sprinklered car parks and to get hold of their effect on the visibility within the car park. The first design option is to increase the distance between the sprinklers and the smoke layer to maintain the sprinklers’ spray region below the smoke layer. The second design option is to increase the minimum threshold of the sprinklers’ operating pressure to 4–6 bars. The third design option is to change the common 4-MW steady fire curve and use a transient fire curve with unsteady heat release rate by implementing the ASHRAE decay equation. Regarding the sprinkler system network, six deluge networks are used, where each system relies on three smoke detectors located above the parked cars for the activating signal. Flashover stage is a fast transition from the growth stage fire to the fully developed fire.
