In the process of office building work management, the most concern is the safety of personnel entrances, especially for the internal safety management of office buildings, and more efforts have been put into it. Of course, there will be a certain pressure on management costs. Many office buildings are installing QR code reader instead of rfid reader, The purpose of replacing the access control with QR code is to make the management of security work more convenient and take better usage advantages. First of all, although traditional access control cards also have good advantages in use and are more convenient to enter and exit at ordinary times, this traditional type of access control card is very easy to be copied, and a large number of copies may be copied in a minute, which will cause a lot of problems. A serious security risk. If you use a QR code to access the door, you can enter the door by scanning the QR code to effectively prevent the access control from being copied. Secondly, the access control card is always lost or forgotten. This causes great troubles in life and work. If the QR code access control system is replaced in an office building, everyone can directly scan the QR code on the mobile phone to open the door. Entry and exit are also very safe. As long as the other party does not have a QR code issued by himself, there is no way to enter Thirdly, the use of a QR code access control system in office buildings can better promote the quality of property management, especially to better protect the safety environment in the office building, and reduce the pressure of property management work, because the owner can directly scan the code APP to vistor, which will reduce the various workloads of the property.

An electromagnetic lock, magnetic lock, or maglock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail-safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking devices are unlocked when de-energized. Direct pull electromagnetic locks are inherently fail-safe. Typically the electromagnet portion of the lock is attached to the door frame and a mating armature plate is attached to the door. The two components are in contact when the door is closed. When the electromagnet is energized, a current passing through the electromagnet creates a magnetic flux that causes the armature plate to attract the electromagnet, creating a locking action. Because the mating area of the electromagnet and armature is relatively large, the force created by the magnetic flux is strong enough to keep the door locked even under stress. Typical single door electromagnetic locks are offered in both 600 lbs. (2669 N) and 1200 lbs. (5338 N) dynamic holding force capacities. A "fail-safe" magnetic lock requires power to remain locked and typically is not suitable for high-security applications because it is possible to disable the lock by disrupting the power supply. Despite this, by adding a magnetic bond sensor to the lock and by using a power supply that includes a battery backup capability, some specialized higher security applications can be implemented. Electromagnetic locks are well suited for use on emergency exit doors that have fire safety applications because they have no moving parts and are therefore less likely to fail than other types of electric locks, such as electric strikes. The strength of today's magnetic locks compares well with that of conventional door locks and they cost less than conventional light bulbs to operate. There are additional pieces of release hardware installed in a typical electromagnetic locking system. Since electromagnetic locks do not interact with levers or doorknobs on a door, typically a separate release button that cuts the lock power supply is mounted near the door. This button usually has a timer that, once the button is pressed, keeps the lock unlocked for either 15 or 30 seconds in accordance with NFPA fire codes. Additionally, a second release is required by fire code[1]. Either a motion sensor or crash bar with an internal switch is used to unlock the door on the egress side of the door automatically. Principle The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. OperationThe magnetic lock relies upon some of the basic concepts of electromagnetism. Essentially it consists of an electromagnet attracting a conductor with...

The automatic sliding door openers seem to be designed to automatically open and close ,but the internal integration technology is fundamentally different. Moreover, our country currently has no industry regulations in this regard, so it is inevitable that some factories are shoddy. If users lack some relevant knowledge, it is difficult to judge whether the automatic door opener is good or bad. What problems should be pay attention to when choosing an automatic sliding door opener? 1: Checkup the horsepower of the motor. That is, what people usually ask is, how large or multiple doors can this door open? People's habit is always to simply think that the larger the size of the door opener, the greater the strength. In fact, the power of the motor is determined by the rotor parameters (diameter, stacking thickness) and the motor magnetic tile. 2: Checkup the waterproof performance of the motor. The waterproof performance of the motor is determined by the outlet and the sealing ring of the bottom cover. Comparing the S4A ED100 sliding door motor with the imitation products on the market, it is easy to find that the outlet of the S4A ED100 sliding door motor is fully sealed and has a special waterproof treatment, and the bottom cover sealing ring is made of oil-resistant rubber seal ring. 3: Check up the life of the motor. The selection of materials and manufacturing techniques for the worm gear, output shaft sleeve, reducer volute, rotor support structure, mounting seat and other parts of the motor determines the length of the motor's service life and the ability to resist bumps and shocks. Just like the worm gear of S4A ED100 sliding door motor, it is precision manufactured with high-performance materials with wear-resistant formula, large modulus, large tooth width, and good overall rigidity. 4. How to choose the type of automatic door operator in the market? If the flow of people is small, the door opening is normal, and the investment budget is small, such as an office or office, you can choose an ordinary door operator with a lower price. Such as:DL-45,DL-60 and DL-80 door closer,This type of door operator can generally be used without trouble 5. Pay attention to the compatibility of the automatic door operator. The door operator is required to have compatibility and be able to install these devices. Some automatic door machines have this kind of function and are easy to install, such as: ED100 Swing door opener, but some door machines don't have this function, and they must be equipped with many devices to install, which leads to unnecessary expenses.

The shared QR code is valid for a short time;7. The two-dimensional code opening permission can be flexibly set through the access control software: which mobile phone can open which door and which time period;8. There will be records and queries when opening the door by QR code! Quickly generate temporary QR code The decoration workers of a company need to have free access rights during the decoration period or the new employees during the trial period. In this case, the property only needs to use the QR code access control software to generate a short-term effective binding with the company’s internal employee information You can print the QR code or send it to the company’s management through Online tools.

Solution for telescopic doors with access control systemsClients requirement are as below:1:Access controller required Bidirectional way, RFID reader IN & OUT, Punch RFID cards to unlock the door, no need exit button 2: Automatically detect the doors if the cars approaching and after XX meters, it will be closed it. 3: The normally open, normally closed magnetic sensor is used to filter the microwave sensor's door closing signal. When the telescopic door is in the closed state, the magnetic sensor is in contact, and when the Telescopic door is opened, the magnetic sensor is in the off state. When the telescopic door is closed, the magnetic sensor has no contact, the door will sound an alarm, and the card swiping is invalid at this time. Due to the unstable closed state of the Telescopic door, sometimes deviation or not in place, the door sensor may not work at this time, resulting in the failure of swiping the card to open the door, so it is recommended to fix the Telescopic door with a magnet with larger magnetism. (The door magnetic sensor terminal is fixed on the wall, depending on the site, the magnetic section is fixed on the  telescopic door, the location is based on the site)4: Wiring of the telescopic door wireless control sensor. Unscrew the screws on the back cover, use a multimeter to measure the terminals of the switch, some of which are divided into positive and negative poles, and then use a soldering iron to lead out the ‘on’ and ‘off’ signal wires.5:Please place the telescopic door control switch in a hidden place, so as not to allow someone to directly press the telescopic door control switch to open and close the door without swiping the card.6: The entire system does not support the suspension of the  telescopic door switch at the moment, it needs to be developed later! This is our team configured by experience, as below:
