TCP/IP RFID Elevator Access Control Board – 40-Floor Lift ACU
TCP/IP RFID Elevator Access Control Board – 40-Floor Lift ACU
TCP/IP RFID Elevator & Cabinet Access Control Board – Up to 40 Floors
Take full command of your building's vertical and storage security with the Asia-Teco CW20/CW40 TCP/IP RFID Elevator Access Control Unit (ACU). Designed for commercial and multi-story residential buildings, this advanced lift controller uses RFID card authentication and a Wiegand-compatible interface to restrict floor access and manage up to 40 cabinet doors — all from a single, centralized system.
Two Powerful Modes in One Controller
🏢 Elevator / Lift Floor Access Control
Install just one card reader per lift and assign floor privileges to each cardholder. Authorized users can select only the floors they are permitted to visit. Security personnel and administrators can be granted full-floor access via privilege settings. Multi-floor cardholders can choose their destination from their permitted floors — unauthorized floor buttons remain inactive.
🗄️ Cabinet & Locker Access Control
Pair the controller with Adroitor management software to operate up to 20 doors (CW20) or 40 doors (CW40) simultaneously. A single card swipe opens the assigned cabinet. Administrators can unlock all doors at once from a PC for inspections, and time-based privileges allow cleaning staff access after hours. Compatible with fingerprint readers, face-recognition terminals, and any Wiegand-format biometric device.
Key Features
- TCP/IP Network Connectivity — Manage the system remotely over your existing LAN/WAN infrastructure.
- Wiegand Interface — Works seamlessly with standard RFID card readers and biometric devices (fingerprint, facial recognition).
- Up to 40-Floor / 40-Door Support — Cascade a second expansion board to scale from 20 to 40 outputs without replacing the main controller.
- Dual Relay Outputs (Elevator Board) — Each circuit provides Normally Open (NO) and Normally Closed (NC) contacts (NO/NC/COM interface).
- Single Relay Outputs (Cabinet Board) — Each circuit provides a Normally Open (NO) contact plus door-contact signal feedback (NO/GND/S interface).
- Fire-Signal Safety Trigger — In the event of a fire alarm, expansion board relays activate sequentially to release all cabinet doors automatically.
- Fail-Safe Power Design — Expansion board relay NO contacts remain disconnected from the power supply positive pole during power-on or power-off transitions.
- Door Magnet Feedback — Connect door magnets to the S input and GND of each expansion board channel for real-time status monitoring.
- CE Certified — Meets applicable European conformity standards for safety and electromagnetic compatibility.
- Models Available: CW20 (up to 20 doors/floors) & CW40 (up to 40 doors/floors)

Important Notes
- For systems managing more than 20 doors, one additional cabinet expansion board is required (cascade connection).
- It is strongly recommended to install the additional expansion board in a dedicated controller box for easier wiring and maintenance.
- The wiring method for systems with fewer than 20 doors and those with more than 20 doors follows the exact same diagram — simply add the second expansion board.
- Elevator expansion boards and cabinet/locker expansion boards are different products — verify your application before ordering (elevator boards feature NO/NC/COM; cabinet boards feature NO/GND/S).
Who Is This For?
This system is ideal for commercial office buildings, hotels, hospitals, warehouses, co-working spaces, and residential high-rises that need granular, card-based floor or storage access management without running separate wiring for each floor or cabinet.

Frequently Asked Questions
Q: What is the difference between the CW20 and CW40 elevator access control models?
A: The CW20 supports management of up to 20 floors or cabinet doors. The CW40, or a CW20 with a cascaded expansion board, supports up to 40 floors or cabinet doors. Both use the same TCP/IP and Wiegand interface architecture.
Q: Can I use a biometric fingerprint or face-recognition reader instead of an RFID card reader?
A: Yes. The system is compatible with any biometric access device — including fingerprint scanners and facial recognition terminals — as long as the device outputs a standard Wiegand (26-bit or 34-bit) signal.
Q: What happens to the cabinet doors if the fire alarm is triggered?
A: When the controller receives a fire signal, the expansion board relays activate sequentially to automatically unlock all connected cabinet doors, ensuring safe and unobstructed egress.
Q: Do I need separate software to manage this elevator access control system?
A: For cabinet management features (remote door release, audit logs, time-based privileges), the system is designed to work with Adroitor management software. Basic elevator floor-restriction functions are managed through the controller's built-in settings and privilege assignments.
Q: Is this system suitable for large commercial buildings with many users?
A: Yes. The TCP/IP network interface allows the controller to be integrated into an existing LAN or WAN, enabling centralized management of multiple controllers, large card databases, and audit trail logging across a multi-story commercial building.
