When does the hotel balcony door use fire doors?

Fire doors are used when smoke-proof hanging walls are installed in the evacuation walkways and closed walkways of hotel box doors. According to Article 5.5.30 of Code for Fire Protection Design of Buildings (GB 50016-2014) (version 2018), the fire doors of buildings frequented by people should be normally open, which should be automatically closed in case of fire and have signal feedback function. It is worth noting that fire doors are generally not used in other places except for evacuation walkways and closed walkways with smoke-proof hanging walls. Therefore, fire doors should be used when installing smoke-proof hanging walls in evacuation walkways and closed walkways for hotel balcony doors.
