The Smoke Ventilation Control or SVC complies with the European standard EN12101-10 and has been specially developed for use on industrial drives (230V) with or without integrated frequency controller and digital limit switches. In the event of fire, the SVC controls the door to a set height. In conjunction with a roof hatch control, one or more hatches are opened in the roof, creating an air flow that removes smoke via the hatches in the roof. The SVC is equipped with a controlled emergency power supply (1N~230Vac / 2000VA) which, in the event of a power failure, guarantees that the door can still be opened to the set height for up to 72 hours after the power failure. The complete menu is easy to set, using the rotary/push button and the display on the printed circuit board and the door control. Simply select the desired parameter and set the functions as desired. Thanks to an assembled cable available in different lengths, complete with plugs, it is very easy to connect the SVC to a GFA frequency-controlled drive.
