Emergency exit systems ensure safe escape and rescue routes in your building in the case of danger. People must be able to leave the building rapidly. Stringent regulations apply for building safety. The emergency exit control unit (door control unit) allows the use of an emergency exit for authorised persons during daytime operation. In an emergency, it opens to anyone. In addition, this central control unit controls the intelligent interaction of all door components. It secures and monitors all opening and closing operations at the door.
