TCP/IP 20/40 Door Cabinet & Elevator Access Control Kit

TCP/IP 20/40 Door Cabinet Locker Controller & Elevator Floor Access Control Kit

Take your building security to the next level with the Asia-Teco CW20/CW40 TCP/IP Access Control System — a powerful, scalable solution engineered to manage up to 40 locker cabinet doors or control elevator floor access from a single card reader. Whether you're securing a storage room, mailroom, office lockers, or managing multi-floor elevator privileges in a commercial building, this all-in-one controller board and expansion interface kit delivers professional-grade access management with ease.

Made in Mainland China.

Key Features

• Dual-Mode Control: Manages both electric cabinet/locker systems (up to 20 or 40 doors) AND elevator floor access control from a single TCP/IP controller.
• Scalable Architecture: Start with up to 20 doors using one expansion board; cascade a second board to expand control to 40 doors without additional wiring complexity.
• Fire-Safety Integration: On fire signal detection, the expansion board relays trigger sequentially to automatically open cabinet doors for safe evacuation compliance.
• Two Expansion Board Variants:
  • Elevator Expansion Board: Each circuit includes dual relays — Normally Open (NO) and Normally Closed (NC) — with NO/NC/COM interface ports for full elevator floor button management.
  • Cabinet Locker Expansion Board: Each circuit features a single Normally Open (NO) relay plus a door-contact signal feedback port (S), with NO/GND/S interfaces for door-status monitoring.
• Privilege-Based Access: Assign single-door, multi-door, or all-door privileges per user card. Administrators and security staff can be granted full-floor or full-cabinet access.
• One Card Reader, Many Doors: Replace the traditional "one reader per door" model with a smart "one controller, many doors" architecture — ideal for shared locker banks and elevator lobbies.
• Biometric Compatible: Supports Wiegand-format readers including fingerprint scanners, face recognition devices, and standard RFID card readers.
• Software Integration: Compatible with Adroitor access control software for centralized PC-based management — open all doors at once for inspections, cleaning, or administrative tasks.
• Safe Power States: When powered on or off, the expansion board relay NO remains disconnected from the power supply positive pole, preventing unintended door activations.
• CE Certified: Meets CE safety and electromagnetic compatibility standards.

Use Cases

Elevator / Lift Floor Control

Deploy a single card reader in the elevator cab and let the system handle floor privileges automatically. Users with multi-floor access can select their destination; unauthorized floors remain locked. Security and administrators can access all floors per their privilege settings.

Cabinet & Locker Bank Management

Assign specific lockers to individual users — swiping a card opens only the authorized cabinet. Administrators can open all doors simultaneously for inspections or end-of-day cleaning, all managed from a central PC with Adroitor software.

Technical Specifications

Wiring Notes

• The door magnet must be connected to the S input port of the corresponding cabinet door on the expansion board and to the expansion board's GND.
• For systems managing more than 20 doors, add a second expansion board and cascade it using the provided connection diagram.
• Wiring diagrams for sub-20 and over-20 door configurations follow the same connection method.
• For best results, install additional expansion boards in dedicated controller enclosures to simplify wiring and future maintenance.

Frequently Asked Questions

Q: What is the difference between the elevator expansion board and the cabinet locker expansion board?

A: The elevator expansion board includes two relays per circuit — a Normally Open (NO) and a Normally Closed (NC) — with NO/NC/COM interface ports, enabling full elevator floor button control. The cabinet locker expansion board uses a single Normally Open (NO) relay per circuit with a door-contact signal feedback port (S), using NO/GND/S interfaces for individual locker door monitoring and control.

Q: How many doors can this TCP/IP access control system manage?

A: The CW20 model manages up to 20 doors with a single expansion board. By cascading a second expansion board (CW40 configuration), the system scales to manage up to 40 doors from the same TCP/IP controller.

Q: Can I use a fingerprint reader or face recognition device instead of a card reader?

A: Yes. The system is compatible with any Wiegand-format input device, including RFID card readers, fingerprint scanners, and facial recognition terminals. This gives you flexibility to choose the authentication method that best suits your environment.

Q: What happens to the cabinet doors during a fire alarm?

A: When a fire signal is detected, the expansion board relays are triggered in sequence to automatically open all cabinet doors, facilitating safe and rapid access during emergency situations.

Q: Does the system require special software for management?

A: Yes, the system integrates with Adroitor access control software, which allows administrators to manage all doors, assign user privileges, open multiple doors simultaneously for inspections or cleaning, and monitor access logs from a central PC.
