Basic knowledge of engineering business door to select disable lock products
Access control for electric lock is an important part of access control system, is the executing agency and the key equipment of the access control system, assuming that the entrance guard system is a person's words, the lock is like the hands and feet. The stability of the whole control system. Suppo. Suppose a access control system controller and card reader are all very good, there is a problem with the quality that the lock, can also cause the door cannot open, influence the acceptance and use of Technology
Note: the purchase of domestic or imported import lock lock lock? It is too expensive, the price will be more than one thousand pieces, sold to users without two thousand blocks down, although the real import electric lock, mature technology, products, low repair rate, but the service is still a problem, if there is a problem, a foreigner not that you Chinese power instability and so on many reasons, is very trouble. I suggest to buy domestic lock it. Cheap many, but mostly produced in Taiwan or in the manufacturing process of Taiwan (Taiwan is the main base of foreign OEM lock) and quality standards, the difference is also bad not arrive where go to
Note two: buy electric plug lock electromagnetic lock or the lock mouth? With what kind of lock, depends on what you have. Double (can open or open) glass door is best to use electric plug locks, internal single open (open or only inside and outside doors open) the best is to use magnetic lock, magnetic lock is called electromagnetic lock. The magnetic lock body is arranged on the upper part of the door, some people will not feel not hidden installation, not beautiful, in fact abroad and are so used, the use of foreign magnetic lock to excess electric plug locks, magnetic locks the stability is higher than that of the electric plug lock however, electrical safety plug lock must be high. Electric lock is installed in the side door and spherical lock mechanical lock with use, safety is much lower, and it is not convenient for wiring, but some are cheap, is not recommended to adopt. Residential use is best to buy magnetic lock and electronic lock, electric control lock the big noise in general, building intercom with all electric control lock, also now have a mute electric control lock, can be considered. However, no matter what the lock must pay attention to rain, is the lock is made of iron, is easy to rust, it should pay attention to. There are many other not too popular and the electric lock, not recommended because of the limited scale of production, application A case of too little, the product is not mature, the best use of the best available in the market. For example, there is a power cut off the electric plug lock, the lock can satisfy the customer after the blackout, the door remains closed requirements, but do not meet fire safety requirements, may pass the acceptance, and the door frame thickness is required, installation will have unexpected trouble. So the little recommendation to the customer
Note three: to buy or to buy its equipment supplier to the factory? Direct purchase of electricity, the price may be low, but your purchasing quantity is limited, may not be able to get a good price and service, and a system controller you find a company to buy, electric lock for a company to purchase, the the problem of mutual shirk responsibility is not good, as good as all controller to suppliers, manufacturers and suppliers for direct production of electric lock controller is generally not, because it does not belong to the electronics industry lock manufacturing industry, and belongs to the mechanical processing industry, they usually through detection and assessment of the trial way lock lock quality, that is well, the controller manufacturers usually adopts OEM way sales, playing their own company's brand, that is responsible for the quality of the product
Note four: electric plug locks the basic common sense to buy.. firstly, the lock surface have metallic luster, can not have obvious scratches, the standby current is about 300mA, the action current of less than 900mA, long time after electrifying, surface slightly hot, but not too hot. The electric plug lock up efforts to fully, press down. After the lock can bounce automatically and powerful. The best 4000 on-off test. Suppose, discovery process locks to bounce, or is not in place, or playing is not up, regarded as unqualified. Some project developers asked: is the purchase of two line or multi line electric plug locks? Is this, many line electric plug locks with single chip microcomputer control, operating current is controlled by single chip intelligent control lock, lock body not too hot, but also has the time delay control function and magnetic detection function. The time delay control functions can adapt to the spring is not good use, function of real time monitoring magnetic monitoring function can provide a door opening and closing state controller. Although these features you may not use, but there are single-chip microcomputer control and SCM control lock without electricity quality and stability of the grade is not a level. It is recommended that you do not have to save a little money. The two line of the electric plug locks, the internal structure is very simple Single, is a current driven solenoid mechanism, working current, serious heat to a certain time will damage the electric lock. Not recommended
Note five: electromagnetic lock of the basic common sense to buy the appearance should be fine, the surface can not have obvious scratches or rust, critical magnetic lock is to see his resistance to tension, the need of professional equipment was measured, so only after installation, with the hand suddenly hard way to pull, pull not open as normal, but must pay attention to the installation electromagnetic lock body is consistent, the iron absorption do not install too tight, otherwise it will affect the pulling resistance.
