Frequently Asked Questions
Q: Is the Asia-Teco EF4-EM RFID reader compatible with third-party access control panels?
A: Yes. The EF4-EM features a standard Wiegand 26–44 bit output interface, which is widely supported by virtually all major access control panels and controllers on the market. Simply connect the D0/D1 Wiegand lines to your panel's reader port.
Q: Can the EF4-EM be used outdoors in harsh weather conditions?
A: Absolutely. The unit carries an IP66 waterproof rating, meaning it is fully protected against powerful water jets and heavy dust. It operates in temperatures ranging from -30°C to 60°C, making it well-suited for outdoor gates, building entrances, and exposed wall installations.
Q: How do I enroll new users or delete existing ones?
A: User enrollment is managed directly at the keypad using the built-in programming menu. You can add or remove RFID cards and PIN codes for up to 1,000 users (990 normal + 10 visitor slots) without any additional software or PC connection required.
Q: What lock types is this reader compatible with?
A: The EF4-EM includes a relay output (NO, NC, Common) with a maximum load of 2A, making it compatible with a wide range of electric strikes, magnetic locks (maglocks), and electric bolt locks. The relay output time is adjustable from 0 to 99 seconds to match your specific lock hardware.
