The essential advantages of the FD20

– More power (+ 50 %) as compared to the precessor FDC
– Faster /more dynamic
– Plug + Play, LCD display on the PCB (end user- and installer-friendly)
– Maximum ease of operation (lighted keys in the side cover)
– Simple resetting procedure for the customer
– D-BEDIX (option)
– More electric power for the external elements (such as sensory system, electric door opener, etc.)
– Single-leaf function (in the event ob bi-parting swing doors, i.e. separately controlled individual door leaves)
– Function Permanently open (without magnetic holding brake)
– Robust, vandal-proof , i.e. the drive unit cannot be damaged by the application of a manual force
– Rugged internal stop piece

Installation and rod assembly versions

– Normal rod assembly 105° (pushing effect)
– Sliding rod assembly (pulling and pushing effect) 105° also suited for fire-protection applications, but in this case: maximum lintel depth approx. 30 mm)
– Intelligent rod assembly fastening on the door leaf


– Each one of the functions can be directly enabled by means of the 5 keys on the side cover
– Push + Go feature, fast and smooth response
– The accelerating function (forceful closing) can be programmed
– The starting torque can be programmed
– A closing sequence and motor lock delay can be programmed
