Frequently Asked Questions

Q: What types of RFID cards are compatible with the Asia-Teco S603EM access control reader?

A: The S603EM supports standard 125kHz proximity cards and key fobs using ASK (EM format) modulation — the most widely used RFID format in access control. These are readily available from most security and electronics suppliers. Note: it is NOT compatible with 13.56MHz HF cards such as MIFARE.

Q: Can this RFID access control system work as a standalone unit without a computer or network?

A: Yes! The S603EM is a fully standalone access controller. All user programming — adding or deleting cards and PIN codes — is done directly at the keypad. No computer, software, or network connection is required, making installation straightforward and cost-effective.

Q: What types of locks can be connected to the S603EM door access controller?

A: The unit features a relay lock output with both NO (Normally Open) and NC (Normally Closed) modes, making it compatible with most electric strikes, magnetic locks (maglocks), and electric deadbolts. The lock strike release time is also programmable to suit your specific hardware.

Q: Does the S603EM support Wiegand integration with larger access control panels?

A: Yes. The S603EM includes a standard Wiegand output, allowing it to be used as a reader peripheral connected to a larger access control panel or management system, giving you flexibility for future expansion.
