record FTA 20 FBO – Kayar katlanır panik açılımlı kapılar
A special feature is the optional «break-out» function (FBO), permitting the record FTA 20 to be used as an escape door in accordance with local conditions and regulations. As with the TOS (Total Opening System) of our automatic sliding doors, the FBO enables swing doors to function as emergency exits by opening in the direction of escape as quickly as possible.
The FBO folding door was specially developed for use in escape and rescue routes. In normal use, the door panels fold inwards. In emergencies, access to escape and rescue routes is provided by light pressure on the door panel. This frees the track from its mountings, allowing the door panel and track to open outwards.
