Frequently Asked Questions
Q: What type of RFID cards does the Asia-Teco A3D-EM access control system support?
A: The A3D-EM is compatible with standard 125KHz EM proximity cards and key fobs. It does not support higher-frequency cards such as 13.56MHz Mifare cards. When purchasing replacement or additional cards, ensure they are 125KHz EM format for full compatibility.
Q: How do I add or delete users without a computer or keypad?
A: The A3D-EM uses a Management Card system. You simply present the management card to the reader, then present the user card you wish to enroll or delete — no PC, software, or keypad required. This makes day-to-day administration quick and straightforward.
Q: Is this RFID access controller suitable for outdoor installation?
A: Yes. The A3D-EM carries an IP55 waterproof rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. It also operates reliably across a temperature range of -10°C to 60°C, making it well-suited for outdoor entryways, gates, and covered exterior installations.
Q: What power supply does the A3D-EM require?
A: The controller operates on DC 12V with a working current of ≤ 100mA. A standard 12V DC power adapter or access control power supply is required (sold separately). Ensure your power supply is stable and rated for continuous use.
Q: Can I extend the card reading range beyond the standard 1–10 cm?
A: Yes. The A3D-EM supports connection to an optional external/extended antenna, which can increase the card reading distance beyond the built-in 1–10 cm range. This is useful for vehicle access gates or situations where longer-range detection is preferred.
