The Powerturn has been approved for use on fire protection doors up to a maximum of 600 kg. All details of opening times refer to an ideal door without loads due to wind pressure. The maximum permissible loads due to wind pressure or impact pressure per type of installation depend to a great extent on other door elements such as seals, locks, brushes etc.
For transom installation opposite hinge side the calculated opening time must be increased by one second (min. opening time = calculated opening time + 1s).
For all types of installation, the closing time must be increased by one second based on the opening time (min. closing time = opening time + 1s).
All details are applicable to the automatic drive.
