Access control lock knowledge summary!

A, anode lock:

To open the lock for power off, meet the fire protection requirements. It is installed in the upper part of the door frame. Unlike the electromagnetic lock, the anode lock is suitable for two-way wooden doors, glass doors, and fire doors. It is equipped with a door magnetic detector which can detect whether the door is closed at any time.

Second, the cathode lock:

It is mounted on the side of the door and must be used with a mechanical lock.

Advantages: Cheaper prices. There are two kinds of power off and power off.

Disadvantages: Inrush current is relatively large, which has a great influence on the stability of the system. Since it is installed on the side of the door, the wiring is inconvenient. Because there is a partition between the side door frames, the line is inconvenient to drop down from the top of the door through the door frame. The lock body must be hollowed out and buried. It is difficult to install. Without swiping the card, the door can be opened by a spherical mechanical lock, which reduces the safety and queryability of the electronic access control system. The destructive power that can endure is limited, and it may be kicked off. In principle, Aopport does not recommend using this type of electric lock.

Third, electronic control lock:

Mainly used for cell unit gates, bank deposits and other two occasions. It can also be opened with a knob or key that is locked in the door.

Disadvantages: Large inrush current, large impact on the stability of the system, and loud noise when opening the door. Inconvenient to install, often require professional welding equipment, spot welding to the iron door. Pay attention to the construction, the door open delay can not be long, can only be set within 1 second, if the time is long, it may cause electric control lock heat damage.

In response to these shortcomings, the new “Mute Electric Control Lock” is simply called “Mute Lock”, and some people are also called “Motor Lock”. It is designed so that instead of using the electromagnet principle, it drives a small motor to retract the lock. head.

Fourth, mute lock (motor lock)

Other electric locks, such as glass door locks, magnetic locks in the up and down of the lock, etc., due to the use of electric locks are not large, and some are still facing out, here is not introduced
