Product Overview
The ACM-WG20K Lift Controller Security Cabinet Locker Controller System and Elevator Controller Access Control Board provides a specialized solution for managing multiple access points through a single card reader interface. Unlike traditional “one for one” access control systems where each card reader controls a single door, this system enables “one for more controllers” functionality. This architecture is essential for vertical transportation management, secure cabinet access, and multi-zone facility control in commercial buildings, hotels, office towers, and industrial complexes.
System integrators and project contractors choose this solution when they need to control multiple floors, locker banks, or secured zones without installing separate readers at every access point. The system distinguishes user privileges at the controller level, allowing authorized personnel to access only designated areas while maintaining comprehensive event logging and audit trails.
Product Advantages
- One Reader, Multiple Controllers: A single Wiegand-format card reader or biometric device can manage up to 20 access points, reducing hardware costs and installation complexity
- Elevator Floor Access Control: Restrict floor access based on user credentials. Cardholders can only reach floors they are authorized to access, and multi-floor privilege users can select their destination after card authentication
- Cabinet and Locker Management: Integrate with management software to assign specific lockers or cabinets to individual users. Swipe a card and the assigned compartment opens automatically
- Centralized Administration: Administrators can open all doors or lockers simultaneously from a PC for inspections, cleaning, or emergency access
- Flexible Credential Support: Accepts Wiegand 26-bit or 34-bit format devices, including card readers, fingerprint scanners, and facial recognition terminals
- Large Capacity: Supports up to 20,000 users and stores 100,000 offline event records for complete audit capability
Key Features
- TCP/IP communication with 10M/100M self-adaptive Ethernet for reliable network integration
- Card + Password authentication mode for enhanced security where required
- Time profile management for scheduling access permissions by time of day, day of week, or holiday schedules
- Peripheral control support for integrating with relays, locks, alarms, and indicator systems
- Fire signal input for emergency override functionality
- Unlimited networking capability for large-scale deployments across multiple elevators or locker banks
- Event buffer storage of 100,000 records ensures data retention even during network interruptions

Industrial Applications
Elevator Access Control: Deploy in buildings with 10 or more floors where each floor represents a restricted zone. Authorized users swipe their card at a lobby reader and the system enables only the floors they are permitted to access. Multi-floor privilege holders can select their destination after authentication. Security personnel and administrators can be granted universal floor access based on privilege settings.
Cabinet and Locker Management: Ideal for office environments, fitness centers, healthcare facilities, educational institutions, and industrial changing rooms where individual lockers or cabinets must be assigned to specific users. The system integrates with management software for real-time assignment changes, usage tracking, and bulk door operations.
Multi-Zone Facility Access: Suitable for laboratories, data centers, warehouse zones, and restricted storage areas where a single entry point controls access to multiple internal compartments or sections.
Commercial Building Management: Property managers can implement floor-level access restrictions for tenants, cleaning staff, maintenance crews, and visitors with centralized control and full audit trail capability.
OEM / ODM Manufacturing Support
As an established manufacturer with 20 years of production experience in RFID and access control products, we offer comprehensive OEM and ODM services for the ACM-WG20K controller system. Customization options include:

Project contractors and system integrators benefit from our ability to adapt the controller architecture to meet unique deployment requirements without compromising reliability or certification compliance.
Factory Production Advantages
Our manufacturing facility maintains quality inspection procedures at every stage of production. Each controller board undergoes functional testing before packing to verify communication, input/output operation, and event logging accuracy. We have established supply chain relationships that ensure consistent availability of components for both small sample orders and large-scale project deployments.
Production lead times are approximately 1 to 5 days for sample quantities and 7 to 30 days for bulk orders, depending on configuration and volume. We support multiple shipping methods including express courier, air freight, and sea freight, and can provide export documentation such as Certificate of Origin, FTA, Form F, and Form E to facilitate customs clearance.
Bulk Supply and Project Deployment Support
Wholesale buyers and project distributors benefit from our ability to supply consistent, uniform product batches suitable for multi-site deployments. The system architecture supports unlimited networking, making it suitable for large commercial buildings, hotel chains, corporate campuses, and government facilities requiring centralized access control management.
Each order undergoes pre-shipment quality verification to ensure all boards function correctly. Our packing process protects circuit boards during transit, reducing the risk of damage during international shipping. We offer EXW, FOB, CIF, and CFR trade terms to accommodate different procurement requirements.
FAQ
Q: How many doors or floors can one controller manage?
A: The ACM-DT20 main controller works with ACM-DT20K extension panels. One ACMB-DT20 board supports two extension panels, each providing 20 output ways, enabling control of up to 20 access points per controller configuration.
Q: Can I use biometric readers with this system?
A: Yes. The controller accepts Wiegand 26-bit or 34-bit format input, which is compatible with most fingerprint readers, facial recognition terminals, and other biometric devices that output Wiegand protocol.
Q: What happens if network connectivity is lost?
A: The controller stores up to 100,000 event records in its buffer. When network connectivity is restored, all offline events are uploaded to the management software, ensuring no audit data is lost.
Q: Is this system suitable for retrofitting existing elevator installations?
A: Yes. The controller connects between the existing elevator floor selection panel and the elevator control system. It intercepts floor button signals and grants access based on cardholder privileges, making it suitable for both new installations and retrofit projects.
Q: How are user privileges configured and managed?
A: User privileges, time profiles, and access schedules are configured through the Adroitor management software via the TCP/IP network connection. The software supports individual user settings, group assignments, and bulk configuration updates.
Q: Can the system integrate with building fire alarm systems?
A: Yes. The controller includes a fire signal input that can override access restrictions during emergency situations, allowing unrestricted floor access or door release as required by safety protocols.
Q: What is the warranty period for this controller board?
A: All products carry a 2 to 3 year warranty against manufacturing defects, excluding damage caused by improper installation, misuse, or external factors.
