Application difference between electromagnetic lock and electric lock in access control system

July 31 , 2023

The switch locks used to control the door in the access control system are mainly electric locks and electromagnetic locks. How do they work and how are they wired? Why two? Each has advantages and disadvantages and characteristics. Let’s talk about the current mainstream electronically controlled locks first. To be precise, compared with the old models, they should be called electric locks. It takes less than a second to open the door when the power is turned on, and automatically closes the door within 5-8 seconds. The structure and requirements are as follows:

Wiring is also simple, as follows:

Installation instructions: If you need to connect the positive unlocking control signal, please connect the lock terminal "L-" with a short wire in "GND", otherwise you cannot control the unlocking


L+ is connected to the NO of the access control power supply, and L- is connected to the GND of the access control power supply. As shown in the figure above, L- should be short-circuited with GND in the lock body. If you need a positive unlocking control signal, usually do not supply power to the lock body, and when working, give the lock body an instantaneous voltage to unlock the lock.


Next, let's take a look at the electromagnetic lock.


Electromagnetic locks are also called magnetic locks. Generally, they are powered by 12V DC. When you swipe your face or swipe your card to the access control machine, the power will be turned off to unlock and open the door. The installation position of the magnetic lock is more flexible than that of the electric control lock, and the position is mainly at the upper end or side end of the door.

When the lock body is working normally, the indicator light of pulling the lock body is on. When a trigger signal is sent from the access control machine, it will cause the magnetic lock to work, that is, power off, unlock and open the door. At this time, the light is off. Magnetic locks are often used outdoors, so waterproofing is a prerequisite for ensuring their longevity. Relatively speaking, magnetic locks are durable and rarely broken, while electric locks are often burned out. The door is opened only when the power is turned on. If the power is turned on for more than ten seconds, it is very likely that the lock body will be burned. The magnetic lock is a long-term power supply, but the door lock is only opened when the power is cut off.
