Frequently Asked Questions
Q: What RFID card types are compatible with the K2F access control keypad?
A: The K2F operates on the 13.56 MHz RFID frequency, which is compatible with standard ISO 14443 Type A/B cards, including widely used formats such as Mifare Classic, Mifare DESFire, and similar 13.56 MHz smart cards. It does NOT support older 125 kHz EM cards.
Q: Does the K2F work without a smartphone or internet connection?
A: Yes. You can unlock the K2F using a registered RFID card, fingerprint, or saved PIN passcode at any time — no smartphone or internet connection is required for these methods. The TTLOCK app and cloud features enhance management capabilities but are not required for basic day-to-day access.
Q: How many users can I add to the K2F system?
A: The K2F supports up to 20,000 RFID card users and 100 fingerprint records. Passcode and eKey users are managed through the TTLOCK cloud platform, allowing flexible user management for offices, apartments, and commercial facilities.
Q: Is the K2F suitable for outdoor installation?
A: Absolutely. The K2F carries an IP66 waterproof rating, meaning it is fully protected against powerful water jets and dust ingress. Its aluminum alloy and tempered glass construction makes it well-suited for gate entrances, outdoor doors, covered exteriors, and similar environments.
Q: What power supply does the K2F require?
A: The K2F is powered by a DC 12V supply. It is typically wired directly to a power source as part of an access control installation, often alongside an electric strike or magnetic lock. Please refer to the included wiring diagram for installation details.
