The fire dampers with tripping and control mechanism KW1 and RST close in effect of the action of the driving spring located in the mechanism, actuated by operation of the fuse-element, electromagnetic trip or manually by the tripping lever. Opening of the fire dampers occurs manually lever (RST) or remotely after applying by using a wrench (KW1 mechanism), pulling the supply voltage to the actuator MERCOR KW.theThe fire dampers with actuators BELIMO of series BE or BLE open and close in result of supplying the supply voltage to the actuator terminals (the actuator does not have a return spring). Fire dampers can be also opened or closed manually, by using a wrench. One should open the damper with a hexagonal wrench placed in the socket in a steady and slow way with precaution. Too rapid key motion may cause damage of the actuators internal mechanisms or of the current transmission set.
