Panic bar
Vision decreases significantly with age and thus represents a disability for broad sections of the population. In order for people with poor eyesight to find their way around buildings, information must be presented in high contrast and according to the two-sense principle. At least two senses (seeing, hearing or feeling) should be addressed simultaneously. In this way, the missing or limited perception can be compensated by another sense. With the panic bar, operation is conveyed via two senses: the doubled handle area made of coloured polyamide visualises the handling and can also be sensed by touch. The door opens when pressure is applied against the horizontal operating rod. By marking the optimum pressure point according to the two-sense principle, the panic bar meets the requirements of DIN 18040 for barrier-free construction.
