The function of heat and smoke extraction structures (NRWG) is to remove the generated smoke from the building in the event of a fire. The control system receives the signals, so in the event of a fire or smoke, the doors will automatically open to a certain degree; they must open within 60 seconds of the smoke occurring. Its counterparts are the air supply structures, which also open to the alarm with the motor operation. MARSHALL has a CPR number which authorizes us to manufacture these windows.
