21、rformance and requirements for smoke control dampers that are to be used in conjunction with pressure differential systems and smoke and heat control systems. They can also be used to pressurize when gas extinguishing systems are used.Particular reference is made to EN 1366-10, which defines the fur
22、nace testing associated with these products and EN 13501-4, which provides details on their fire resistance classification.In addition to the prevention of transmission of smoke and combustion products from a fire zone, smoke control dampers are utilized to contain the spillage of otherwise harmful
23、and toxic extinguishing gases from the affected area and for the control of pressurizing and excess air relief within pressurization systems.Smoke control systems are designed to fulfil the following basic functions. a) The extraction of smoke from a single fire compartment to the outside of the bui
24、lding.b) The extraction of smoke from fire compartments of a building, using a SHEVS connected to one or more fire compartments. The smoke control system duct may or may not pass through other compartments of the building to reach the outside of the building.c) The use of pressurization to maintain
