The positioning of the frame-mounted actuator (hidden behind side frame profile) depends on the type of actuator selected. It is installed on either side frame (on the left or right) and with a typical operation time of 20-60 seconds. With electric versions there is an optional device to reduce the speed and force of the closing louvres in order to reduce the risk of finger trapping.
The following performance attributes follow tests to EN 14351-1:2006 (the standard for windows and doors). The exact performance attribute will depend on the chosen size, controls, and louvre type.
