In addition to the monitoring, access control, alarm and other technical defense facilities that are commonly used at present, intelligent building security must also combine human defense and physical defense. The key to civil air defense is to rely on a security team with excellent quality and a sound management system. Anti-requirement of durable perimeter facilities, gated facilities, etc. Relative to the electric lock, from the point of view of the fixed assets investment of the building, the preliminary budget and post-maintenance of the electric lock hardware products must also be fully considered; from the consideration of building fire protection design, it must be ensured that the selected products can be guaranteed to the maximum extent in an emergency. The rapid evacuation of personnel; from the perspective of the decoration of the building, the aesthetics of the product or the application of the product that is subject to the overall style of the building is also very important; from the perspective of different functional applications of the intelligent building, the functional requirements for the building hardware or electric lock are also different. of. Based on this, when selecting the building intelligent electric lock product, it is necessary to consider the structure, function, style, fire protection, security level and other factors of the construction project, and select the most suitable product solution to recommend to the owner. Emergency escape. To ensure the safety of all personnel in the building and ensure that they can escape in the shortest time in any emergency, it is necessary to fully consider the need to be able to open in emergency situations when selecting power distribution locks and hardware products. All escape doors, which are embodied in the selection of electric locks, are generally provided with a type of power-off type lock at these specific positions; Fire prevention. Fire prevention and escape are interrelated. When a fire occurs, priority should be given to ensuring the escape of personnel in the intelligent building. Secondly, the fire door and the fire shutter facility should be safely and securely isolated from the fire to ensure the safety of personnel. Electric locks and hardware products must be compatible with the fire rating of the building; Internal management functions. Different functional partitions within the system will have different management rights. In the aspect of electric lock and hardware matching, it must be combined with the internal management of intelligent buildings, and the facilities and equipment should be properly installed in the required places to ensure the isolation of personnel in different functional zones; System durability. The service life of a building with an intelligent building is currently more than 100 years old, but it is often seen that many electric locks or hardware products in building buildings are facing a lot of repair or replacement after several years of use, so the process of selecting related products In the middle, we cannot simply pursue low prices, but we must comprehensively judge and choose the most cost-effective products; Channel control. Different channels are designed in intelligent buildings, which are standardized from different functions such as function and flow. When designing electric locks and hardware products, these design concepts must be followed to fully meet the design requirements and meet the logic of channel flow control. ; It is convenient for people with disabilities. At present, the state has relevant regulations on barrier-free access. It is reflected in the construction lock hardware to ensure that people with disabilities can open every access door with any part of the body to protect their passage and personal safety. Carefully evaluate the product and make the most user-friendly design; The aesthetic requirements , each architect will choose a certain architectural style when designing, this style will be reflected in all aspects of the building, so in the selection of distribution locks and hardware products, we must fully understand and respect the designer's The ideas and styles, the products used to meet the overall aesthetic needs of the building. Lock standard introduction In the process of electric lock and hardware selection, different standards are often encountered. At present, the commonly used standards are European standard and American standard. The current standards in the world of locks and hardware mainly include the following: · British Standard BS (BS5872-1982) is the oldest; The one-way comparison for the European standard and the American standard is as follows. 1. American National Standard: ANSI 156.4, American Underwriters Laboratories UL10C. Selection principle In summary, when selecting intelligent building electrical locks and hardware solutions, it is recommended to follow the following basic selection principles: TAISHAN CITY WANAN CABLE CO.,LTD , https://www.tswanan.com
Intelligent public buildings have the following requirements in the selection of electric locks and hardware products:
· European standard EN (PREN12529) is all-encompassing;
· The American standard ANSI (ANSI 156.2-1999) is the most complete;
· Australian Standard AS (AS4145.2-1993) is the most stringent “trade barrierâ€;
· Japanese standard JIS (JISA1510-1995) is more relaxed.
· The number of standard opening times: ≥ 2 million times;
· The number of secondary standards open: ≥ 1 million times;
· The number of three levels of standard opening: ≥ 500,000 times.
2, European standard CE: EN1154 (performance test) and EN1634 (fire test), open times indicator: ≥ 500,000 times.
It can be seen from the above comparison that the durability parameters of American standard products are generally higher than those of European standard products, which is also the reason why the American standard electric locks or hardware products are relatively expensive on the market.
For a large commercial building, the number of doors may be thousands or even thousands. How to choose the best cost-effective electric lock and hardware solution for different parts and different use requirements to ensure a long service life and the lowest maintenance in the future is a very complicated and cumbersome work. The best overall hardware lock solution should be a unit of convenience, safety and durability.
The location used and its importance should be considered for use in gates, hall doors, rooms, bathrooms or passages in order to select the product that suits the desired function;
The environment and conditions used must consider the advantages and disadvantages of the use environment, such as the frequency of use, whether it is a fire door, the structure of the door, weight, thickness, etc.
Consider the situation of people who are frequently used and consider whether there are elderly people, children or people with disabilities;
Considering the coordination with the decorative environment, it should be considered that the coordination and matching with the decorative environment should be consistent;
