and related requirements is intended to prevent the distribution of smoke through the supply air duct system and, preferably, to exhaust a significant quantity of smoke to the outside.Neither function, however, guarantees either the early detection of fire or the detection of sm[r]
Overpressure dampers are used to equalize the pressure between adjacent rooms and for automatic interruption of air supply or air exhaust. Volume control dampers regulate the air flow volume in ventilation ducts and air conditioning devices. Throttling, shut off and non return dampers and flow rate[r]
