S4A Access key tags or key fobs can come in a variety of shapes and designs to suit different purposes and preferences. Here are some alternative shapes and styles S4A can provide for key tags.What is the role of the access control keychain?An access control keychain, often referred to as an access control key fob or keytag, plays a crucial role in the field of security and access control systems. Its primary role is to provide a convenient and secure way for individuals to gain access to restricted areas, buildings, or resources. Here's a more detailed breakdown of the role of an access control keychain:Authentication and Identification: Access control keychains are typically assigned to authorized personnel or individuals. Each keychain is associated with a unique identifier, such as a serial number or RFID (Radio-Frequency Identification) tag. When presented to an access control system, this identifier is used to verify the person's identity and determine their access privileges.Access Control: Access control keychains are used to control entry and exit to secure areas. They enable or disable access based on the permissions associated with the keychain's identifier. This helps prevent unauthorized individuals from entering restricted zones.Convenience: Keychains are compact and easy to carry, making them a convenient method for individuals to access secured locations. Users can simply present their keychain to a reader, and the system will respond accordingly, either granting or denying access.Enhanced Security: Access control keychains enhance security by reducing the risk of unauthorized entry. Unlike traditional keys that can be easily duplicated, keychains with electronic identifiers are much more difficult to clone or replicate. Additionally, lost or stolen keychains can be quickly deactivated in the system to prevent misuse.Audit Trail: Many access control systems log access events, including when and where keychains were used. This audit trail provides valuable information for security personnel, helping them monitor and investigate any suspicious activities or breaches.Integration: Access control keychains can be integrated into broader security systems, including video surveillance, alarm systems, and visitor management systems. This integration enhances overall security and provides a comprehensive view of access-related events.Time-Based Access: Some access control systems allow administrators to set specific time-based access rules. Keychains can be programmed to grant access only during certain hours or days, further controlling and securing access.Multi-Functionality: In addition to physical access control, keychains can be used for other purposes, such as cashless payments within a facility, tracking attendance, or managing equipment loans.Visitor Management: For temporary access, keychains can be issued to visitors or contractors, allowing them limited access during their visit. These keychains can be easily deactiv...

A magnetic shear lock, also known as an electromagnetic shear lock or maglock, is a security device commonly used in access control systems to secure doors. It consists of two main components: an electromagnet mounted on the door frame and a metal plate attached to the door. When activated, the electromagnet generates a strong magnetic field that holds the metal plate in place, preventing the door from being opened.Here is a detailed description of a magnetic shear lock:Design and Installation: A magnetic shear lock typically features sturdy construction with an electromagnet encased in durable housing. The electromagnet is installed on the door frame, while the metal plate, often made of steel, is fixed to the door. The two components align when the door is closed, allowing the electromagnet to secure the door effectively.Working Principle: When an electric current passes through the electromagnet, it generates a powerful magnetic field. This magnetic field attracts the metal plate, creating a secure bond between the door frame and the door. The magnetic force is strong enough to withstand a significant external force, providing a reliable barrier against unauthorized entry.Control and Activation: Magnetic shear locks are typically controlled by an access control system, which can include keypads, card readers, biometric devices, or centralized control software. When a valid access credential or command is received, the control system activates the magnetic shear lock, allowing the door to be securely locked or unlocked.Advantages of Magnetic Shear Locks:Strength and Security: Magnetic shear locks offer high-strength locking capabilities, providing a robust level of security. The magnetic force between the electromagnet and metal plate is difficult to overcome, making it challenging for unauthorized individuals to force open the door.Fail-Safe Operation: In the event of a power failure, most magnetic shear locks are designed to release automatically, ensuring that occupants can safely exit the premises without being trapped inside. This fail-safe feature enhances safety in emergency situations.Quick Response Time: Magnetic shear locks can be activated and released rapidly, allowing for efficient access control. This is especially beneficial in high-traffic areas or during emergency situations where quick access is crucial.Durability and Low Maintenance: These locks are typically built to withstand heavy use and adverse environmental conditions. With no moving parts, they have a longer lifespan and require minimal maintenance compared to mechanical locks.Versatility: Magnetic shear locks can be used with various door types, including wooden, glass, and metal doors. They are suitable for both interior and exterior applications, offering flexibility in their installation.It's worth noting that while magnetic shear locks provide strong security for access control, they may not be suitable for all applications.

1. Classification of electric Dropbolt LockElectric Dropbolt Lock can be divided into two-wire, five-wire, eight-wire, etc.; according to different use occasions, such as five-wire, eight-wire and other multi-wire electricDropbolt Lock basically have the function of door magnetic signal detection. In some access control systems, users need to see the real-time opening and closing status of the door on the access control software interface, then they need to choose this electric mortise lock with door magnetic signal detection.2. How to judge the quality of electric Dropbolt Lock?1. When you get the electric dropbolt lock, check whether the surface of the lock body has obvious scratches, and the lock body should have a metallic luster.2. After the power is turned on and the power is turned on for a long time, whether the surface of the lock body is hot, whether the bolt of the electric mortise lock is fully ejected, and whether the bolt springs back forcefully after pressing the bolt.3. Whether the Dropbolt Lock is an ultra-low temperature electric lock, so that the Dropbolt Lock will not get hot during repeated operation, thereby prolonging the service life of the electric Dropbolt Lock.4. Whether the electric Dropbolt Lock has an anti-intrusion circuit design. Some electric Dropbolt Lock on the market are locked by magnetic induction. When the magnetic force artificially disappears or the magnetic force is weakened, the latch springs back to unlock. At the actual installation site, there is a certain gap between the small magnetic plate and the lock body of the electric Dropbolt Lock. Once the magnetic force between the magnetic plate and the lock body is blocked by a small object, the lock body will automatically open because it does not sense the magnetic force. deadbolt. This kind of electric Dropbolt Lock will inevitably have certain security risks. The electric Dropbolt Lock with anti-intrusion circuit protection is locked by sensing the magnetic force of the small magnetic sheet. Once the electric mortise lock is locked, the electric mortise lock can only be opened by receiving the door opening signal or power off. Because of the presence or absence of the magnetic force of the small magnetic sheet, the safety of the Dropbolt Lock is affected.Author: Written by Ms.He from S4A INDUSTRIAL CO., LIMITED
