How does the projector choose access control electric lock?

Guide to buy access control locks _ purchase notes：

Access control electric lock is an important part of the access control system is the implementing agencies and key equipment of access control system.If the system were a person, the electric lock is in people's hands and feet. Related to the stability of the entire access control system. If an access control system’s controller and card reader are both good, but the quality of the electric lock is not good, it will also cause the door can not open and so on, which affects the acceptance and usage of the project.

Note 1: Purchase electric bolt lock or magnetic lock?

What kind of lock be equipped, you have to see what kind of door you will use.

The bi-direction glass door is best to use electric bolt locks.

The company's internal unidirectional wooden doors are best to use magnetic locks.

Magnetic locks are also called electromagnetic locks. The lock body of a magnetic lock is installed in the upper frame of the door.The stability of the magnetic lock is higher than the electrical lock, but the safety of the electrical lock is higher. So the residence community is best to use magnetic locks and electronic control locks.

However, no matter what the lock will use, we should also pay attention to the rainproof, the lock is made of iron, is easy to rust.

It is not suggested to use some unpopularized locks that are produced restrictedly, few applied and undeveloped. For example, there is one kind of electric bolt on the market, which can keep the door closed when power fails. And customers are satisfied with it. But it can’t meet the fire fighting requests, which may lead to failure in acceptance test. Moreover, trouble will be caused in installation because of its requirement of door frame thickness. In a word, such locks are less recommended.

Note 2: Purchase lock from manufacturers or from an access control supplier?

Purchase the lock from manufacturers directly, the price may be lower, but if you purchase a limited number, it may not be able to get a good price and service.

If you buy access control from one company and buy locks from another company if problems happened, maybe they will Shirk responsibility for each other, so It is suggested to purchase all from controller supplier.

Generally the controller manufacturers and suppliers do not produce electric locks directly, because the electric lock manufacturing industry does not belong to the electronics industry, and it belongs to the machinery processing industry, they will generally pass the test and trial  assess the quality of the lock factory lock, if not bad, the controller manufacturers will generally use the OEM way to sell, playing their own brand, and responsible for the product quality.

Note 3: The common sense for choosing electric lock.

• First, the lock surface to have metallic luster, can not have obvious scratches,
• Second, standby current is about 300mA, the active current is lower than 900mA, a long time after power on, the surface slightly hot, but not scalding.
• Third, The bounce strength of electric lock need to be enough, the lock head can bounce up after the press.

Note 4: Purchase two lines or multi-line electric lock?

Multi-line electrical lock, like five lines and eight lines electric lock, all of them have a single-chip, the electric lock is controlled by the micro controller intelligent, the lock body will not t0o hot, and has a delay control function and the door magnetic detection function.

Delay control function can be adapted to the use of poor spring door, door monitoring function for the controller to provide door open and close status of the real-time monitoring function. Although these features You may not have to use, but an electric lock with single-chip is much better than an electric lock without single-chip and, the quality and stability of the grade is not at a level.

So we recommend you do not have to save a little money. Two-wire electrical lock, the internal structure Very simple, just a current-driven electromagnetic coil mechanism, the working current is large, a serious heat to a certain time will damage the electric lock, not recommended.
