RFID Access Control Module – Door Lock & Elevator Board 10-24V
RFID Access Control Module – Door Lock & Elevator Board 10-24V
Asia-Teco Embedded RFID Access Control Module – Intercom, Elevator & Door Lock Controller
Take full command of your entry points with the Asia-Teco Embedded Access Control Module (H4004D/H4004C). Designed for seamless integration into intercoms, elevators, and door-lock systems, this compact yet powerful board supports up to 3,000 users and reads both 125KHz EM and 13.56MHz Mifare RFID cards — giving you flexibility across virtually any existing card infrastructure.
Whether you're securing a single door or building a multi-door access network, this module delivers enterprise-grade features in an embeddable form factor — all powered from a convenient 10–24V DC supply.
Key Features
- Dual-Frequency RFID Reading: Compatible with 125KHz (EM) and 13.56MHz (Mifare) cards for broad device compatibility.
- 3,000-User Capacity: Store and manage up to 3,000 individual user credentials; user data can be synchronized across multiple linked modules.
- Administrator & Programmer Included: Ships with a remote control programmer and a master administrator card for quick, out-of-the-box setup.
- Multi-Format Wiegand I/O: Supports multi-format Wiegand output/input for easy integration with third-party access control panels and readers.
- External Door Contact & Alarm Support: Connect external door-contact magnets and alarm devices directly to the board's dedicated terminals.
- Double-Door Interlock Function: Coordinate two doors so only one can be open at a time — ideal for air-lock or mantrap-style entry points.
- Visitor User Mode: Grant time-limited or single-use access to visitors without modifying your main user database.
- Coercion Prevention: Built-in protection detects forced-entry scenarios and triggers the alarm output.
- Pause Mode & Toggle Mode: Flexible door-control modes — including toggle-switch mode — let you tailor operation to your application.
- Super Administrator / Super Password: Override capability allows an authorized super-admin to open doors under any condition.
- Automatic Duty Function: Scheduled access routines reduce manual intervention during regular operating hours.
- Wide Operating Range: Functions reliably from -40°C to +60°C (-40°F to 140°F) and 10%–98% RH — suitable for indoor and outdoor installations.
- CE Certified: Meets CE conformity standards for electromagnetic compatibility and safety.

Frequently Asked Questions
Q: What RFID card types are compatible with the Asia-Teco H4004D/H4004C access control module?
A: The module supports 125KHz EM cards, 13.56MHz Mifare cards, and combined EM+Mifare cards. This dual-frequency capability makes it compatible with the vast majority of standard RFID access cards and key fobs used in commercial and residential systems.
Q: How many users can be stored on this RFID access control board?
A: The module stores up to 3,000 individual user credentials. User data can also be synchronized across multiple linked modules, making it scalable for larger multi-door deployments.
Q: Can this module be integrated with an existing intercom or elevator control system?
A: Yes. The embedded design and multi-format Wiegand input/output allow the module to connect to intercom systems, elevator controllers, and third-party access panels. It also supports external door-contact magnets and alarm devices via dedicated terminals.
Q: What power supply does the access controller require?
A: The board operates on 10–24V DC, making it compatible with a wide range of standard security power supplies. Idle current draw is ≤40mA and working current is under 100mA, so it is energy-efficient in continuous operation.
Q: What is the double-door interlock function and when would I use it?
A: The double-door interlock ensures that only one of two connected doors can be unlocked at any given time. This is ideal for security vestibules, air-lock entries, or mantrap configurations where you need to confirm one door is fully closed and secured before the second can be opened.
