Access control management system, as the most common system in weak current, is used in daily life. The application of access control systems is extremely wide. There will be access control systems in various communities, office buildings, shopping malls, and other places. The access control has multiple functions such as door access control, real-time monitoring, security, and anti-theft alarm. It mainly facilitates the entry and exit of internal employees and prevents outsiders from entering and exiting at will. It not only facilitates internal management but also enhances internal security, thereby providing users with an efficient And economical working environment.
Electric locks are usually used in access control systems. Take a simple access control system as an example. It is composed of an access control host, an access control card reader, a door opening button, an electric lock, and management software. The electric lock is an important part of it.
The function of the electric lock in the access control system is mainly used to control the opening and closing of the door. At present, the commonly used electric locks in the access control system mainly include magnetic locks, electric bolt locks, The following S4A will introduce them to you one by one.
1. Magnetic lock series
1.1 Principle of Magnetic Lock
The design of the magnetic lock is the same as the electromagnet. It uses the principle of electromagnetism. When the electric current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force, which will tightly attract the iron plate to achieve the effect of locking the door. The access control system that controls the power supply of the electromagnetic lock will cut off the power after identifying the correct personnel, and the electromagnetic lock can open the door when it loses its suction.
1.2 Classification of magnetic locks
Magnetic locks can be divided into single-door magnetic locks and double-door magnetic locks. Single-door magnetic locks are mainly used for single-opening doors, and double-door magnetic locks are used for double-opening doors.
At present, the commonly used brackets on the market mainly include LZ type and U type. The LZ type can be applied to the door with a frame underneath, the L bracket is used to fix the magnetic lock on the door frame, and the Z type bracket is fixed on the door. U-shaped can be applied to the lower frameless door (direct card into the entry), the installation diagram is as follows.
2.1 Principle of electric mortise lock
The electric mortise lock is also a kind of electronic control lock, which drives the extension or retraction of the "bolt" through the on and off of the current to achieve the function of locking or opening the door. The key component in the lock body is the "lock tongue", which can be combined with the "lock hole" to achieve two states of "closed" and "opened". That is, the lock tongue is inserted into the lock hole to close the door, and the lock tongue leaves the lock hole to open the door.
2.2 Classification of electric mortise locks
There are generally two types of electric mortise locks, which are suitable for doors with and without borders.
2.3 Description of installation method of electric mortise lock
The electric mortise lock can open the door when the power is off, and the door can be opened at 180°, which is suitable for glass doors.
For framed glass doors, electric mortise locks need to be equipped with U-shaped brackets. Frameless glass door, no need to be equipped with brackets.
