Abstract：According to the characteristics of super high‑rise buildings above 250 m and relevant specifications,the difficulties and key points in the design of automatic fire alarm system for super high‑rise buildings are analyzed and summarized from 5 aspects,i.e. the type of automatic fire alarm system,ring bus design,fire control video surveillance system,design of automatic fire alarm system for high and large spaces and fire detection for small electrical shafts,and corresponding solutions are put forward. The application of solutions are explained based on project cases.
