TCP/IP 40-Floor Elevator & Cabinet RFID Access Control Panel
TCP/IP 40-Floor Elevator & Cabinet RFID Access Control Panel
TCP/IP 40-Floor Elevator & Cabinet RFID Wiegand Access Control Panel
Take command of your building's access with the LUCKING DOOR CW20/CW40 TCP/IP Wiegand Access Control System — a professional-grade controller designed to manage up to 40 floors or 40 cabinet doors from a single card reader. Unlock via RFID card swipe, PIN entry, or any Wiegand-compatible biometric device (fingerprint reader, face recognition, etc.). Made in Mainland China.
What's the Difference Between the Elevator and Cabinet Expansion Boards?
- Elevator Controller Expansion Board: Each circuit features two relays — one Normally Open (NO) and one Normally Closed (NC) — with NO/NC/COM interfaces. Ideal for floor-button control in lifts.
- Cabinet/Locker Expansion Board: Each circuit features one relay — Normally Open (NO) only — with NO/GND/S (door contact signal feedback) interfaces. Purpose-built for locker and cabinet door management.
Key Features
- Scalable Up to 40 Doors/Floors: Manage up to 20 doors/floors with the base unit; cascade a second expansion board to reach up to 40 doors/floors.
- TCP/IP Connectivity: Network-ready for remote management and real-time monitoring via PC software (Adroitor compatible).
- Wiegand Interface: Compatible with a wide range of readers — RFID cards, PIN keypads, fingerprint scanners, and face recognition devices.
- Fire Safety Integration: In the event of a fire signal, the expansion board relays trigger sequentially to automatically release cabinet/locker doors for emergency egress.
- Privilege-Based Access: Assign per-user floor or cabinet privileges. A user with multi-floor access can select their destination floor; unauthorized floors remain locked. Administrators and security personnel can access all floors.
- One Card, Multiple Doors: Break the traditional "one card reader per door" limitation — one reader controls up to 40 outputs.
- Power-Safe Design: Relay NO and the positive power supply remain disconnected when the controller powers on or off, preventing unintended door/cabinet releases.
- Door Magnet Feedback: Connect door magnets to the S input port and GND of the expansion board for real-time door-open/closed status reporting.
- CE Certified — No high-concern chemicals.
Use Case Examples
Elevator / Lift Floor Control
Install a single card reader inside the elevator cab. The system reads the card, identifies the user's permitted floors, and activates only those floor buttons. Users with multi-floor privileges select their destination; restricted users cannot press unauthorized floor buttons. Administrators and security staff can reach any floor based on their privilege level.
Cabinet & Locker Management
Swipe a card and only the assigned locker opens. Administrators can use the PC software to open all doors simultaneously for audits or inspections. Cleaning staff can be granted time-limited all-door access for after-hours maintenance. Works seamlessly with biometric readers that output Wiegand signals.
Wiring Notes
- Systems up to 20 doors use the base controller only; systems from 21–40 doors require one additional cabinet expansion board cascaded to the base.
- Adding a second expansion board? Install it in a new controller enclosure for clean wiring and easy maintenance.
- The wiring diagram is identical for both the sub-20 and 21–40 door configurations.
- Door magnets must be connected to the S input port and GND of the corresponding door channel on the expansion board.

Frequently Asked Questions
Q: Can this TCP/IP access control board manage both elevator floors and cabinet lockers at the same time?
A: No — the elevator expansion board and the cabinet/locker expansion board are different hardware variants with different relay configurations. The elevator board uses NO/NC/COM relays for floor-button control, while the cabinet board uses NO/GND/S relays for locker door feedback. Select the correct variant for your application at the time of purchase.
Q: How many doors or floors can the CW40 system manage, and can I expand it later?
A: The base CW20 controller handles up to 20 outputs. By cascading one additional expansion board you reach the CW40's maximum of 40 doors or floors. The wiring method is the same for both configurations, making expansion straightforward.
Q: What types of card readers and biometric devices are compatible with this Wiegand controller?
A: Any device that outputs a standard Wiegand signal (typically Wiegand 26-bit) is compatible — including RFID proximity card readers, PIN keypads, fingerprint scanners, and face-recognition terminals. This gives you the flexibility to use the credential technology that best fits your facility.
Q: What happens to the doors or cabinet locks if there is a fire alarm or a power outage?
A: In a fire alarm scenario, the expansion board relays trigger sequentially to release all doors/cabinets, supporting emergency egress. On power-on or power-off, the relay NO contacts and the positive power supply remain disconnected, so doors do not inadvertently open or close due to power fluctuations.
Q: Is the Adroitor software included, and what can an administrator do from the PC?
A: The system is compatible with Adroitor management software (check with the seller for licensing details). From the PC, an administrator can open all doors simultaneously, assign or revoke individual user privileges, review access logs, and configure time-based access schedules — all over the TCP/IP network connection.
