August 17 , 2023

In the access control system, according to the different access control locks, the working principle of access control is also different. Usually there are access control electromagnetic locks, access control electric mortise locks, and access control motor locks. , Swing gate access control, etc., let's introduce the working principles of these different types of access control systems.


Working principle of access control electromagnetic lock


An electromagnetic lock is basically a combination of an electromagnet and an iron block. It relies on electricity to generate magnetic force and pulls the iron block to lock the door. The strength of the electromagnetic lock is usually calculated according to the number of kilograms of the magnetic force. In the case of power failure, and because of the factors mentioned above, this kind of lock will automatically unlock when the power is turned off.

Working principle of access control electric mortise lock


The electric mortise lock looks like an active bolt, and the electric lock mouth is like a deadbolt installed on the door. The essence of this kind of lock is mechanically fixed, but according to the default position of the bolt, there can be a power-off unlocking type (the bolt is turned off after the power is off. , the lock tongue automatically retracts) and the power-on unlocking type (the latch and the lock tongue automatically pop out after power failure). These two locks can choose the type of lock according to the needs of the actual situation. For example, the general office area will use power-off unlocking type electric mortise locks and electric locks to facilitate the dispersal of personnel in case of fire or other accidents that may cause power outages. In archive rooms, computer rooms and other places where there are few people coming in and out and high security requirements, you should choose electric mortise locks and electric locks with power-on unlocking to ensure the safety of indoor items in case of accidental power failure.


Working principle of access control motor lock


Compared with the several electric locks mentioned above, the electric lock is even more high-end. It has a complete key lock structure, and an electric locking/unlocking device is added to it, which can control the opening and closing of the lock with a circuit. After the power is cut off, it can also be locked and locked like a normal key lock. Applicable to more places, the quotation is also higher. For the backup battery, in the above-mentioned several locks, except the motor lock, it cannot be opened and closed normally after power failure. If necessary, a backup battery can be added to the access control system circuit. Depending on the battery type (usually lead-acid battery) and capacity, it can usually keep the access control system working for several hours to tens of hours after a power failure.
