[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fireproof partition with a certain fire resistance, located between fire compartments, evacuation stairwells, vertical shafts, etc. It is specially used to isolate fire sources in housing buildings. It plays a huge role in firefighting. Once a fire occurs, people can get escape opportunities through fire doors. According to the opening state, they are divided into normally closed fire doors and normally open fire doors. Normally closed fire doors are generally composed of fire door leaves, door frames, door closers, sealing strips, etc. Double or multiple normally closed fire doors are also equipped with sequencers. Normally closed fire doors usually do not require electrical professionals to provide automatic control design, but there are some special cases such as: normally closed fire doors on evacuation passages. When some large construction parties have management requirements such as anti-theft, they should be designed by electrical professionals to reduce safety hazards as comprehensively as possible. For normally open fire doors, in addition to all the accessories of normally closed fire doors, fire door release switches must be added, and automatic control design must be provided by electrical professionals. It is usually used in evacuation passages with more people and logistics, but the existing fire doors have some shortcomings, such as:
