The Facility codes in the access control IC card usually range from 1 to 255 in the standard 26-bit Wiegand format. However, the values and meanings of the Facility codes may vary for different access control systems and card formats:

Wiegand format

1. Standard 26-bit Wiegand format: This is a widely used industrial standard. In this format, the facility code (Facility codes) occupies 8 bits, the maximum facility code is 255, and each facility code can have a card ID number from 1 to 65,535, up to 65,535.

2. 34-bit Wiegand format: The length and position of the facility code may vary. For example, some 34-bit formats may have an 8-bit facility code starting from Bit#2; while another 34-bit facility code may be 12-bit, starting from Bit#21.

Other formats

1. M1 card: The M1 card is a common access control IC card type. Its data structure does not directly correspond to the clear Facility codes field in the Wiegand format. The first 4 bytes of sector 0, block 0 are the card number, the 5th byte is the check bit, the 6th to 8th bytes are the card type, and the last 8 bits are the manufacturer code. The card's permission management and other functions are mainly achieved through the read and write control of sectors and blocks.

2. CPU card: CPU card has higher security and more complex instruction system and data structure. It is usually used in access control systems with extremely high security requirements. Its permission management is often achieved through internal operating systems and applications. Different from the traditional concept of Facility codes, it may involve more key management, identity authentication and other mechanisms.

Typically, the operating voltage of a fail-safe electric strike lock is 12V DC or 24V DC. For example, The ES-100B and ES-110 B of S4A Access Control also have an operating voltage of 12V DC, and the ES-120B can be customized to 24V. 

Whether an additional power supply is needed depends on the specific situation:

When Integrated with an Access Control System

1. If the access control system has a built-in power supply with the appropriate voltage and sufficient power output to support the electric strike lock, then no additional power supply is required. For example, some advanced access control systems have a 12V or 24V power output interface, which can directly supply power to the fail-safe electric strike lock connected to it.

2. If the access control system's power supply does not match the voltage requirements of the electric strike lock or lacks sufficient power, an additional power supply needs to be added.

Standalone Installation

If the fail-safe electric strike lock is used independently without being integrated into an access control system, an external power supply must be provided to ensure its normal operation. The power supply needs to meet the voltage and current requirements of the lock.

If the electric strike lock malfunctions, the following steps can be taken for repair or part replacement:

Troubleshooting the Malfunction

1. Check the Power Supply

    The first step is to ensure that the electric strike lock is receiving power. Use a multimeter to test the voltage at the power input terminals of the lock. If it's a 12V or 24V lock and the measured voltage is significantly lower or non - existent, check the power source, such as the transformer or the battery backup (if applicable). The power supply wires may also be damaged or loose. Inspect the wiring connections from the power source to the lock and tighten any loose connections.

2. Inspect the Wiring

    Examine the wires connecting the electric strike lock to the access control system. Look for signs of damage, such as cuts, frayed wires, or loose connections. If the wires are damaged, they may need to be replaced. In some cases, improper wiring during installation can lead to malfunction. Make sure the wiring is correctly connected according to the manufacturer's instructions, especially the signal wires (for activation and feedback).

3. Verify the Access Control Signal

    If the power supply and wiring seem fine, the problem may lie in the access control signal. Check if the access control system is sending the correct signal to the electric strike lock. Some access control systems have diagnostic tools or logs that can help identify if a signal is being sent when access is supposed to be granted. If the signal is not reaching the lock, there may be a problem with the control panel, relays, or communication between the system and the lock.

4. Examine the Lock Mechanism

    Sometimes, the problem is with the internal lock mechanism itself. The solenoid, which is responsible for retracting the latch, may be jammed or damaged. Listen for any unusual clicking or grinding noises when the lock is supposed to activate. If the solenoid is jammed, it may need to be disassembled and cleaned or replaced. Also, check the latch and striker plate for proper alignment. If they are misaligned, it can prevent the lock from functioning correctly.

Repair and Part Replacement

1. Replacement of Small Components

    If the problem is identified as a faulty component such as a solenoid or a micro - switch, you can usually obtain replacement parts from the manufacturer or an authorized distributor. To replace a solenoid, first, disconnect the power and carefully remove the housing of the electric strike lock. Locate the solenoid and disconnect the wires connected to it. Then, remove the old solenoid and install the new one, making sure to reconnect the wires correctly.

2. Replacement of the Entire Lock

    If the damage to the electric strike lock is extensive or if it's an older model and replacement parts are not readily available, it may be more practical to replace the entire lock. When replacing the lock, make sure to choose a compatible model that matches the voltage, size, and functionality requirements of your access control system. Follow the installation instructions provided by the manufacturer to install the new lock properly. This includes drilling new holes (if necessary), running wires, and setting up the access control connections.

3. Seeking Professional Help

    If you are unsure about how to repair or replace parts of the electric strike lock, it's advisable to seek professional assistance. A locksmith with experience in electronic access control systems or an authorized service technician from the lock manufacturer can diagnose and fix the problem more accurately. They have the necessary tools and expertise to handle complex repairs and ensure that the lock is installed and functioning correctly.
