Fire door 500 combines innovative functionalities of automatic sliding opening and uncompromising fire protection on escape and non-escape routes. It’s convenient for buildings with high safety requirements and smooth people flow. In case of an emergency, the mechanical spring system forcibly closes the door and transforms it into a swing door to ensure safe evacuation and rescue with new opening possibilities. Door self-closes after that and acts as a fire barrier. Fire resistance EI30, EI60 are used to separate fire sectors and prevent fire spread. The system is equipped with built-in and side safety sensors, providing a safe touchless opening and closing. Better signalization is ensured with a fire switch on both sides. Door can be controlled and maintained remotely via IoT by mobile application. 500 product line is certified and protected by a patent and European 3D model.
