Four points need to pay attention to the choice of access control electric lock

The disabled electric lock is an important part of the access control system and is the implementing agency and key equipment of the access control system. If the access control system is compared to a person, the electric lock is like a human hand and a foot, which affects the stability of the entire access control system. If an access control system controller and card reader are both good, if the quality of the electric lock has problems, it will also cause the door to fail to open, affecting the acceptance and use of the project.

Note one: It is too expensive to buy domestic-made electric locks or imported electric locks. The purchase price must be more than one thousand pieces, and there are no two thousand pieces of them sold in the hands of users. Although the real import of electric locks, the technology is relatively mature, and the product repair rate is low, but the service is still a problem. Once there is a problem, foreigners will always say that you have unstable electricity in China and many other reasons, it is even more troublesome. I suggest buying domestic locks for a lot of price benefits, and most of them are Taiwan's production or integration into Taiwan's manufacturing process (Taiwan is the main OEM base for foreign locks) and quality standards, and the difference is not much worse.

Matters needing attention two: Buy electric lock electromagnetic lock or electric lock to match what kind of lock, depends on what kind of door you are. Double open (can be opened inside or outside) glass door is best used electric lock. The company's internal single-open (only open or only open) doors are best to use magnetic locks. Magnetic locks, also known as electromagnetic locks. 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, are so used abroad, the use of foreign magnetic locks to be extra electric locks. The magnetic lock's stability is also higher than the electric plug lock, but the safety of the electric plug lock is higher. The electric lock is installed on the door side and the ball lock and other mechanical locks are used together, the safety is much lower, and the wiring is not Convenience. However, some of the cheaper prices are not recommended for adoption. It is best to purchase magnetic locks and electronically controlled locks for residential use. The noise of electronically controlled locks is relatively large. General building intercoms are equipped with electronically controlled locks. There is also a silent electronic 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 less popular electric locks that are not recommended. Because of limited production scale, too few application cases, and immature products, it is better to use less. For example, there is a power off lock on the market. This kind of lock can meet the requirement that the door is still closed after the customer's power failure, but it does not meet the requirements of fire protection and may not pass the inspection and acceptance. Moreover, it has requirements for the thickness of the door frame, and there will be unexpected troubles when installed, so it is still less. The customer's recommendation is good.

Note three: whether to buy from the lock factory or purchase from the equipment supplier directly to the lock factory, the price may be low, but you have a limited number of purchases, may not obtain good prices and services, and an access control system Controller you find a company to buy, electric lock to find a company to buy, if the problem is evaded, it is not easy to deal with the problem, it is better to buy from the controller supplier, the controller manufacturers and suppliers generally do not directly produce electricity Locks, because the electric lock manufacturing industry does not belong to the electronics industry, but belongs to the mechanical processing industry. They generally assess the quality of electric locks of various lock factories through tests and trials. If they are good, controller manufacturers will generally adopt the method of OEM. Selling and playing your own company's brand means being responsible for the quality of the product.

Matters needing attention four: The basic knowledge that buys the electric plug locks First of all, the lock surface must have the metallic luster, cannot have the 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 considered unqualified. Some projects ask: Is it a two-wire or multi-line electric lock? This is the case. The multi-line electrical plug lock is controlled by a single-chip microcomputer. The operating current of the electrical lock is controlled by the MCU intelligently, and the lock body is not too hot, and it also has a delay control function and a door magnetic detection function. 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. So I suggest you don't have 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. Not recommended.

Note five: The basic purchase of common sense electromagnetic lock appearance should be exquisite, the surface can not have obvious scratches or rust, magnetic lock is the key to see his resistance, this requires professional equipment to measure it out, so only installed Afterwards, pull it out by hand in a sudden and forceful manner. Pulling is not considered normal. However, attention should be paid to the installation of the electromagnetic lock lock body. The suction iron should not be installed too tightly, otherwise it will affect the pull resistance.
