The door leaf swing Ponzi ALU can be moved with a type of automation that opens the door to swing . The DFA device 127 is constituted by a mechanical arm , which opens the door thanks to its special additional functions , suitable for a wide range of applications. Each movement of the door is controlled throughout its path : the microprocessor evaluates the current position of the door , its speed and the final position in each moment and calculates accurately the optimum movement . This special operation, prevents the arrests of the movement, hard braking and slow-down of the traditional devices . The DFA device 127 is made in such a way as to operate as a normal door closer even in the absence of current . In the case in which the door strikes an object in the opening phase, immediately stops and stores the location of the impact , trying to reach its position , in slow mode. In this way , it is possible to avoid a second violent impact . In the case in which the door strikes an object in the closing phase, is reopened immediately. Depending on the type of installation it is possible to choose the optimal solution between two different types of arms available in different lengths for different depths of architrave . The mechanism generates quiet and self-controlled comfort in rooms used for accommodation for the handicapped , the sick and the elderly The DFA 127 is designed on the basis of the most recent recognized safety rules .
