Common sense in the access control system

1. What products are in the access control system?
The access control system consists of two parts:
(1) Biometrics: the special marks owned by someone as identification marks, such as palm prints, fingerprints, faces ... etc. (2) Symbol identification: the special marks of external objects are used as identification marks, such as passwords , Proximity card, IC card ... etc.

2. What are included in the access control system?
It can be roughly divided into 3 parts: (1) control host: responsible for receiving the signal and identifying the signal, opening and closing the door or sending a report (2) door lock: locking the door, unless the power is turned off or sent, otherwise normal operation The door should not be opened automatically (3) Other accessories: outgoing switch, power supply ... etc.

3. Is the access control system a dangerous factor (such as high-temperature wires are weak current products? In order to avoid some unpredictable fire escape ... etc.), most access control systems are 12v or 24v products.

4. Electric control locks are all controlled by electric energy. Only electric energy controlled locks can be regarded as electric control locks, and electric control locks can be divided into "fail-open" (fail-safe) and "fail-closed" (fail- secure) Two types, such as magnetic locks and electric mortise locks, are door locks when power is turned off.

5. What is "fail-secure"?
Under normal door-closing conditions, the lock body is not energized, but presents a "door lock" state. When the lock is energized via an external control system (for example: credit card reader, card reader), the internal body will act and complete The state of "opening the door" is like a cathode lock.

6. What is "open door after power off" (fail-safe)?
Under normal door-closing conditions, the lock body continues to be energized and assumes the "door lock" state. When the lock is powered off via an external control system (eg, card reader, card reader), the internal body will start to operate and complete The state of "opening the door", such as a magnetic lock.

7. When the power is turned off and the door is opened, will the portal be opened in case of power failure?
It can be used with ups uninterruptible power supply system, such as our rf-7000xx series. Even if it has voltage transformation and voltage stabilization functions, plus a battery, it can become an uninterruptible power supply system, preventing access control holes formed by power failure.

8. Is it good to "open the door after power off"? Is it better to "power off and close the door"?
Basically, this is a problem with different angles: "Power off and open the door": It is applicable to fire protection regulations. Most fires are caused by wire fire. The heat of the fire site can melt the hardware of the hardware door lock and cannot open the door to escape. Many people are buried in the fire due to the inability of the door lock to open the escape and the fire is opened. The advantage of opening the door when the power is off is that once the power line is fired and the power outage is triggered, the smoke-proof door of the passage will act to prevent the spread of smoke, and people can easily Open the door and escape. "Power off and close the door": it is suitable for some treasury, and other high security property access control occasions. At this time, we can use the electromechanical lock and the cathode lock together with the lock core. Once the personnel are in danger, you can still use the rotary Twist or key to open the door.

9. Why can't the door be closed normally after installing the two-way door lock?
After the door lock is installed, the door cannot be opened and closed normally. This is a problem encountered by most people. However, most of the real reasons are not the problem of the lock (maybe a small part is the negligence of human installation). Imagine a lock that is only responsible for the switch. , How to make the door return to the position correctly? Of course not! Therefore, most of the problems stem from the quality of the door floor Spring. Simply put, assuming a door weighs 120 pounds, how many pounds of floor springs should be installed? You may say that 120 pounds or more pounds, but some manufacturers do not pay attention to the problem of pounds, 120 pounds of doors, may be installed 80 pounds, or even lower door problems, then Then, when used at the beginning, the problem is not big. When used for a long time, the door cannot return to the home position, the door returns slowly, and the door sags seriously. These problems will gradually emerge in the future. Therefore, when you install a shear lock or an anode lock, the problem arises, so when you want to install a two-way lock, first take a look at the positioning of the door, and change the floor spring of the door.

10. If you don't want to spend money on floor springs, what are the alternatives?
(1) Adjust the floor spring: It is not difficult to say, but if it is not professional, please ask someone (2) Fix the opening direction: change to one-way opening, pull inward,
