Chapter 1 Introduction to the management of fire access doors by the access control system
1.1 Project situation
Shenzhen XX Building Company’s existing 58 fire access doors need to be managed in a unified way. It is required to be normally closed and open automatically when there is a fire alarm. If there is an illegal door opening, the management center can report to the police in time and accurately remind that the door is abnormal. The management personnel can open the door normally through an authorization card when entering and exiting, and the management center has a record of opening the door.
1.2 Solution
It is recommended to use the access control and magnetic lock supporting system to manage all fire access doors in a unified manner. Each fire exit door is equipped with a card reader inside and outside, a 280KG tension magnetic lock (500KG tension magnetic lock can also be installed if you have special needs), and a controller is connected to the management center.
1.3 The advantages of the access control system to manage fire access doors
It is possible to establish a standardized management image for companies, buildings or offices, improve the management level, and standardize the internal management system at the same time.
A proximity card can replace all the keys to the fire exit locks, and has different passing permissions, and the inspectors are authorized to enter the doors within their scope of responsibility with the card. All incoming and outgoing situations are recorded in the computer, which is convenient for inquiring about the time of specific events and fulfilling responsibilities.
Non-inspectors or authorized personnel can be shut out. For example, it is possible to prevent salespersons in industries such as pyramid schemes and insurance from entering the building without permission through the fire exit, which interferes with the normal office order of the building. If there is an illegal intrusion or man-made damage to the fire door and the magnetic lock is damaged, the management computer of the management center can immediately report to the police, and accurately report which door is abnormal, and the management center can immediately notify the relevant personnel to check.
If an employee’s proximity card is lost, it can be reported in the system immediately, so that even if someone else finds the proximity card, they cannot enter the company. This is much more convenient than ordinary fire escape locks. You don’t have to change the lock for safety reasons. The doors are rekeyed. The induction card of the staff who resigned, fired, or left is written off. The employee will not be able to open the fire door with the original authorization card in the future. If you do not adopt the induction card access control management method, you may have to do more just in case. Replace the fire door lock again.
Using advanced international internal encryption protocols, outsiders cannot open your electric locks to enter your premises by mechanical or other high-tech methods. Others, such as password access control and mechanical locks, have no corresponding safety mechanism, and you can easily enter your place through a short circuit or a master key.
The system can be fully turned on automatically in the event of a fire, which meets the fire protection requirements. Mandatory software operations can also be performed. For example, all fire doors are required to be opened during routine inspections. You can open all fire doors through software functions, and restore the system to normal through the software after the inspection is completed.
It can monitor the status of the door and the entry and exit status of the card holder in real time, and can compare and display photos to prevent illegal holders from pretending to enter.

Chapter II Design Principles and Basis Specifications
2.1 Design principles
Due to the need for security and high-efficiency management, the design of the access control system should follow the following principles:
Practicality of the system
The function of the access control system should meet actual needs, not flashy. If one-sided pursuit of the advancement of the system will inevitably result in excessive investment and deviate too far from actual needs. Therefore, the practicability of the system is the first principle that should be followed. At the same time, the system’s front-end products and system software have good learnability and operability. Especially the operability (convenience), so that managers with basic computer operation level can master the operation essentials of the system through simple training, and reach the level of operation that can complete the duty task.
System stability
Since the access control system is an uninterrupted and long-term work system and is closely related to our normal life and work, the stability of the system is particularly important. The product system is required to have more than five years of successful application experience in the market, with a corresponding customer base and customer service system.
System security
While all the equipment and accessories in the access control system operate safely and reliably, they should also comply with relevant Chinese or international safety standards, and can work effectively in non-ideal environments. The powerful real-time monitoring function and linkage alarm function fully guarantee the safety of the user’s environment.
System scalability
The technology of the access control system continues to develop, and the needs of users are also changing. Therefore, the design and implementation of the access control system should take into account the actual needs of future expansion, that is: it can flexibly increase, decrease or update each subsystem to meet the needs of different periods of time. Need to maintain a leading position for a long time and become a model of intelligent buildings. When the system is designed, a reasonable configuration is made for the functions that need to be realized, and this configuration can be changed, even after the completion of the project, the change of this configuration is possible and convenient. The system software will be upgraded and perfected according to the market demand of the developers in different historical periods, and the software will be upgraded for the corresponding application customers. At the same time, it can be extended to all-in-one card projects such as the attendance system, conference sign-in system, patrol management system, and dining management system.
Easy maintenance of the system
The maintenance of the access control system during operation should be as simple and easy as possible. The operation of the system is truly to the extent that it can work when the power is turned on, and it can be operated when it is plugged in. And there is no need to use too many dedicated maintenance tools during the maintenance process. From the configuration of the computer to the configuration of the system, the configuration of the front-end equipment has fully considered the reliability of the system. And implemented the corresponding certification. While achieving the lowest system failure rate, we also take into account that even when problems occur due to unexpected reasons, we ensure the convenient storage and rapid recovery of data, and ensure that the channel can be opened quickly in an emergency. The maintenance of the entire system is online, and the normal operation of all equipment will not be stopped due to the maintenance of some equipment.
Advanced
Under the premise of ensuring stability, practicality and convenience, access control products should have a certain degree of advancement to ensure that they will not be eliminated in the next few years, and can meet the requirements and needs of access control in use.
