Product Overview

The DO-V2000-C Standalone Access Controller is a single-door access control system engineered for industrial and commercial deployment. This unit integrates a 125KHz EM card reader, a backlit numeric keypad, and a programmable relay controller into a compact enclosure. It is designed for system integrators, security contractors, and facility managers who require a reliable, stand-alone access control solution without dependency on a central network host. The controller supports Wiegand 26 output and input, enabling dual functionality as both a master controller and a pass-through reader for upstream systems. With a rated capacity of 1000 active credentials and support for card, PIN, or card-plus-PIN authentication, the DO-V2000-C is suitable for office buildings, warehouse entry points, factory floor gates, and restricted storage areas. The built-in non-volatile memory retains all configuration data during power loss, ensuring operational continuity in mission-critical environments.

Key Features

• Standalone Architecture: Operates independently without a host PC or network controller. All card and password management is performed directly through the onboard keypad, reducing deployment complexity and hardware costs.
• Dual Wiegand 26 Interface: Supports Wiegand 26 output to act as a card reader for third-party controllers, and Wiegand 26 input to accept data from external readers, making it a flexible node in mixed-vendor projects.
• Three-Factor Authentication: Supports card-only, 4-digit PIN-only, or card-with-PIN verification modes, allowing site-specific security policies without firmware replacement.
• High-Sensitivity Reader: The 125KHz proximity sensor achieves card detection and validation in under 0.1 seconds, minimizing gate or door hold-up time during peak traffic periods.
• Rugged Construction: Front panel is fabricated from stainless steel with a brushed finish, resisting corrosion, impact, and vandalism in high-traffic industrial environments.
• Tamper and Door Sensor Alarms: Built-in tamper detection triggers an alarm output if the enclosure is forcibly opened. Door sensor input monitors door position for forced-entry or propped-door alerts.
• Exit and Doorbell Inputs: Dedicated terminals for a wired exit button and a doorbell button, simplifying system wiring without external interface modules.
• Output Short-Circuit Protection: Relay and alarm outputs are protected against short-circuit conditions with a max response time of 0.1 ms, preventing damage to downstream locks and signaling equipment.

Technical Specifications

Industrial Applications

Factory and Warehouse Access: The DO-V2000-C is deployed at perimeter doors, tool cribs, and restricted storage zones where centralized network cabling is impractical. Maintenance teams and shift workers authenticate via proximity card or PIN, while facility managers manage credentials locally through the keypad menu, eliminating the need for a dedicated security workstation.

Office and Admin Buildings: Suitable for interior secure zones such as server rooms, HR record storage, and executive suites. The standalone architecture allows rapid installation during office fit-outs without structured cabling. The door sensor alarm provides real-time alerts for unauthorized door activity during off-hours.

Contractor and Distributor Projects: Security system integrators and access control distributors choose the DO-V2000-C for cost-sensitive commercial projects where a full network-controller deployment is not justified. The Wiegand 26 output allows the unit to feed card data into an existing access control panel, preserving prior infrastructure investment while upgrading credential technology.

Small to Mid-Size Facilities: Property managers operating sites with 5 to 50 doors rely on the standalone controller for its straightforward programming, low per-door cost, and minimal training requirements. The unit supports up to 2000 cardholders, covering most employee populations without a software license fee or annual subscription.
