Commercial buildings, especially some super high-rise buildings or landmark buildings, are often located in the downtown area of the city center, with long business hours, complex types of personnel, and dense crowds. Buildings must not only ensure the normal operation of daily business activities, but also ensure the safety of public and private property and personal safety, so that both safety and security are emphasized. In order to solve the almost contradictory safety requirements of commercial buildings, Xiang An put forward the advanced concept of large security combined with security and fire protection and the following Itemized solutions:
• Reasonably set up safe evacuation routes and facilities to ensure that there is a continuous, barrier-free evacuation route leading to outdoor safe areas anywhere in the building. At the same time, ensure effective fire isolation and rapid evacuation of personnel, and select electronic control delay and alarm functions to effectively solve the contradiction between property safety and personal safety in case of fire
• Adopt reasonable and regulated fire partition design and certified fire doors. Normally closed fire doors feature certified fire hardware for long term fire performance such as firewalls. The normally open fire door adopts an electromagnetic door closer or electromagnetic door suction that is linked with the fire alarm, so that the normally open fire exit door can be closed in time.
• Use automatic doors in barrier-free passages and toilets for the disabled to achieve barrier-free passage; use barrier-free auxiliary facilities with a call system in the toilets for the disabled to ensure the safety of users.
• The door at the junction of the front and rear areas of the building adopts an electronic access control system to limit the abnormal movement of people. In key protected areas, biometric identification technology is used in conjunction with video surveillance and alarm systems to ensure area security.
• Through the card issuing authority setting of the electronic access control system and the mechanical master key system, the access control of internal personnel and the classification and grading management of various rooms are realized. The two systems can be run independently or in parallel.
