The FlipFlow TWIN is an automatic high capacity anti-pass-back system, serving the regulation of passenger flows in airports and other sensitive areas in various types of buildings. Persons can pass through this secure mono block in single file and in one direction only. Attempts to reverse or go back are detected by an intelligent sensor system and, in addition, an alarm message is triggered.
In addition, the FlipFlow TWIN INTERLOCK provides an intelligent interlock function. This mode effectively prevents any unauthorised attempt to throw or hand over objects.
