The appearance should be exquisite, the surface can not have obvious scratch or rust, the key of the magnetic lock is to look at his resistance to pull, this needs professional equipment to measure out, so only after installation, pull by hand suddenly forcefully pull Can not be opened as normal, but should pay attention to the installation of electromagnetic locks to match the suction, the iron should not be installed too tightly, otherwise it will affect the resistance.
Secondly, the lock surface must have a metallic luster, and there should be no obvious scratch. The standby current is about 300mA, and the operating current is lower than 900mA. After a long time, the surface is slightly hot, but it is not hot. The force of the electric plug locks is sufficient, and the lock can spring up and forcefully when pressed down. It is best to perform 4,000 on-off tests. If, during the discovery process, the lock is weak, or it does not pop up, or if it does not come up, it is deemed to be unqualified. Some projects ask: is the purchase of two-wire or multi-line electric lock it? This is the case, multi-line electric lock is controlled with a microcontroller, the operating current of the electric lock is controlled by the MCU intelligent, the lock will not It is too hot, and it has delay control and door detection. The delay control function can be adapted to the poor use of the floor spring. The door magnetic monitoring function can provide the controller with real-time monitoring of door opening and closing status. Although these functions may not be available to you, the quality of the electric locks and the stability of the electric locks controlled by the SCM and the SCM are not on one level. Therefore, it is recommended that you do not need to save a little money. The two-wire electric plug lock has a very simple internal structure and is just a mechanism for current-driven electromagnetic coils. The operating current is large and the heat is severe enough to damage the electric lock. It is not recommended.
Is the purchase of domestic or imported electric locks?
The quality of imported locks is stable, the price is not expensive, and there is quality assurance. Generally speaking, among the brands that can be selected, Korean brands are more affordable than mid-range brands. These brands include Korea Miller, South Korea's Samsung, South Korea GATEMAN and so on. Among them, Miller Korea is the most professional and is a professional lock store for nearly 100 years. As for the price, it is generally around 1200--1500.
Is buying an electric lock electromagnetic lock or electric lock?
What kind of lock to match depends on what kind of door you are. Double open (can be opened inside or outside) Glass door is best to use electric lock, the company's internal single open (only open or only open) wooden door is best to use magnetic lock, magnetic lock called electromagnetic lock. Magnetic lock body installed in the upper part of the door frame, some people do not think it is not hidden installation, not beautiful, in fact, foreigners are so used, the use of foreign magnetic locks to be extra electric locks, magnetic lock stability is higher than electricity Mortise locks, but electric locks are safer. The electric lock is installed on the door side and used with a mechanical lock such as a ball lock. The safety is much lower, and the wiring is inconvenient. However, the price is cheaper and is not recommended. The best use of the district is to buy magnetic locks and electronically controlled locks. The noise of electronically controlled locks is relatively large. The common building intercoms are equipped with electronically controlled locks. Now there is also a silent electric control lock that can be considered. However, no matter what the lock must pay attention to rain, the locks are all iron to do, it is easy to rust, this should pay attention. There are many other non-popular electric locks that are not recommended because of limited production scale, too few application cases, and immature products. For example, there is a power off lock on the market. This type of lock can meet the requirement that the door is still closed after the power failure of the customer, but it does not meet the fire protection requirements. It may not pass through during acceptance, and it is required for the thickness of the door frame. There will be unexpected troubles. So it is better to recommend it to customers.
Is it purchased from a lock factory or purchased from a device supplier?
The purchase of electric locks directly from the lock factory may result in low prices, but you may not be able to obtain good prices and services if you purchase a limited number of them. There is also an access control system controller for you to find a company to buy and an electric lock to find a company to purchase. It is not easy to handle problems that evade each other's responsibility. It is better to purchase all of them from suppliers of controllers. Manufacturers and suppliers of controllers generally do not directly produce electric locks because the electric lock manufacturing industry does not belong to the electronics industry but belongs to the machinery industry. In the processing industry, they generally assess the quality of electric locks at lock factories through tests and trials. If they are good, controller manufacturers will generally use the OEM approach to sell their products and use their own brand to express the quality of the products. Be responsible for.
