1. Network topology map of community access control system Network topology diagram of community access control system A picture. Urgent need... A picture of the network topology diagram of the community access control system.
2. The access control system has long gone beyond simple doorway and key management. It has gradually developed into a complete access management system. It plays a great role in administrative management such as work environment safety and personnel attendance management.
3. The access control system is suitable for various important departments, such as banks, hotels, parking lot management, computer rooms, armory, key rooms, offices, intelligent communities, factories, etc. The access control system has long gone beyond simple doorway and key management, and has gradually developed into a complete access management system.
4. The wiring diagram of the access control system is as follows: +12V on the access control host, the GND end (the power supply of the access control host) is connected to the +12V and GND end of the access control power supply. The NO or NC end of the access control power supply at the front end of the electronic control lock (depending on the usual unlocking and closing);It is usually connected to the NC end (open the lock when the power is on, turn off the lock when the power is turned off).
5. Install the access control in a position that will not be exposed to the sun and rain, and the installation height is 5 meters. You should consider whether there are low obstacles between the outdoor and the indoor, otherwise the signal will drop, affecting the normal use of the telephone access control. Install according to the on-site wiring, and do a good job of grounding at the same time.
6. Access control system and fire fighting linkage can be realized in two ways. First, the electronic lock controlled by the access control system is directly cut off. The second is the logical judgment linkage (indirect linkage) of the access control system. The principle of forced cutting is realized by fire fighting in the access control system. Under normal circumstances, the release signal is DC24V, which requires a DC24V intermediate relay.
1. The wiring diagram of the access control system is as follows: +12V on the access control host, the GND end (power supply of the access control host) is connected to the +12V and GND end of the access control power supply. The front end of the electronic control lock is connected to the NO or NC end of the access control power supply (depending on the normal opening and closing); it is usually connected to the NC end (unlocking on, power-off locking).
2. As shown in the figure below, the overall wiring diagram of this set of access control. Access control attendance all-in-one machine: GND: grounding (GND connected to the access control power supply); 12V: 12V connected to the access control power supply, providing 12V voltage for the access control host; COM: public end; NO: power-on lock (PUSH connected to access control power supply).
3. Connect the access control power supply to 220V first. After connecting the 220V voltage, let's take a look at the wiring port of the access control power supply.
4. The wiring diagram is as above. Introduction: The design of the magnetic lock (or electromagnetic lock) is the same as the electromagnetic magnet, which uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will produce a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door.
1. Convenient glass door access control system provides a variety of access methods, choose at will, no longer bothered to go in and out Annoyed, make your life more convenient. The reliability glass door access control system is controlled by electronic equipment, which is stable and reliable, and the failure rate is extremely low, making your life more secure.
2. Improve safety: glass doorAccess control can effectively control the identity of entry and exit personnel, prevent criminals from entering the access control area, and improve the safety of the place.
3. According to the market survey, the top ten brands of glass door access control systems are summarized, including: Siemens, Shenzhen Dashi, Shenzhen Kesong Electronics, Israel dds security access control, Shenzhen Gate Geely, Ingersolland, Shenzhen Jieshun Technology, Shenzhen OPEN, Hangzhou Cube, Central Control Technology .
4. Improve safety: Access control electric lock can effectively prevent unrighted people from entering the door and improve the safety of entering and exiting the door. Convenient management: Access control electric lock can facilitate managers to manage access control, such as setting the time of switching doors, checking the records of entry and exit personnel, etc.
5. Glass door access control plays a role in enterprise security.A very important role is mainly reflected in the following aspects: 1 Personnel control Glass door access control can control the internal personnel of the enterprise, such as restricting personnel entering and leaving certain areas, preventing the leakage of confidential information, etc.
6. Then press the 60 plus well number key to enter the 8-digit card number plus the well number key to delete a single card. Top ten brands of glass door access control systems: Siemens, Shenzhen Dashi, Shenzhen Kesong Electronics, Israel dds security access control, Shenzhen Gate Geely, Ingersoll Rand, Shenzhen Jieshun Technology, Shenzhen Open Technology, Hangzhou Cube, Central Control Technology.
