Frequently Asked Questions
Q: What types of RFID cards are compatible with this 125kHz access control system?
A: The Asia-Teco K2-EM operates at 125kHz and is compatible with standard EM4100/EM4102-type RFID proximity cards and key fobs commonly available at most security or electronics suppliers.
Q: Does this keypad access controller require a computer or network connection to operate?
A: No. The K2-EM is a fully standalone access control unit. You can program and manage up to 1,000 users directly from the keypad, with no PC, software, or network connection required.
Q: What does "Fail Secure" mode mean for this door lock controller?
A: Fail Secure means that if power is interrupted, the door remains locked rather than unlocked. This is the preferred security mode for offices, server rooms, and any space where unauthorized access must be prevented even during a power outage.
Q: Can I use both a PIN code and RFID card together for added security?
A: Yes. The K2-EM supports three access modes: RFID card only, PIN code only, or a dual-verification mode requiring both card and PIN — ideal for high-security environments.
Q: What power supply does this access control keypad need?
A: The unit requires a DC 12V power supply and draws less than 100mA during operation. A standard DC 12V access control power supply (sold separately) is recommended.
