Benefits

149 101966 EDCD 01

Reliable access device during outages: Local card and event storage ensures uninterrupted door operation even if the network or server fails.

Enhanced security: Alarm monitoring, event buffering, and tamper detection provide strong protection against unauthorized access and system tampering.

System scalability: RS-485 communication allows multiple 149-101966 – EDCD to be connected and managed through a single Site Control Unit.

Flexible integration: Broad reader compatibility supports upgrades and mixed-technology installations without replacing hardware.

High performance: Faster processing and communications compared to standard DCDs improve system responsiveness.

The EDCD stores cardholder access levels locally, with capacity for up to 60,000 cards, and maintains a 2,000-transaction history buffer. It Allows to log events and card activity when communication with the host system is interrupted. It communicates with other Millennium access control devices using a RS-485 twisted-pair, multi-drop polling scheme, ensuring fast and stable system integration.

The device includes two programmable Form C relays rated at 10A @ 24 VDC, typically used to control electric locks or door hardware. It also monitors up to seven alarm inputs, including supervised and normally closed circuits, and can store up to 100 alarm events locally if communication with the control unit is lost.

Reader and Protocol Compatibility

The Enhanced Door Control Device (EDCD) is designed for compatibility with a wide range of readers and communication protocols for Millennium manuals, offering maximum flexibility for both new installations and system upgrades.

Supported Readers and Protocols

Wiegand card readers

  • Configurable data lengths from 0 to 256 bits.
  • Compatible with proximity, smart card, biometric, keypad, and multi-technology readers using Wiegand output.

Magstripe readers

    • Supports ABA / ISO Track 2 formats.

    • Configurable data bits for different card encoding standards.

Clock and Data readers

    • Supports traditional Clock/Data signaling for legacy reader integration.

Marlock readers

  • Direct compatibility with Marlock reader technology.

Supported Readers and Protocols

The Enhanced Door Control Device (EDCD) offers broad compatibility with a variety of readers and communication protocols, making it ideal for both new installations and system upgrades. It supports Wiegand card reader protocols with configurable data lengths from 0 to 256 bits, enabling seamless integration with proximity, smart card, biometric, keypad, and multi-technology readers. Additionally, the EDCD accommodates magstripe readers using ABA/ISO Track 2 formats with configurable data bits, as well as Clock and Data and Marlock reader technologies. This versatility ensures flexible system design, simplifies reader replacement, safeguards existing investments, and enables future system expansion.

Other support application uses

The EDCD accommodates flexible wiring topologies—including home run, daisy-chain, T-tap, and high-security loop-back—ensuring adaptability for both new construction and retrofit projects. Its support for multiple reader technologies and integrated alarm input monitoring makes it ideal for environments that demand unified access control and alarm monitoring within a single, compact controller.

High Performance – Faster Processing and Communications

The EDCD’s faster processing means it can evaluate card credentials, access levels, and door logic more quickly than standard DCDs. When a user presents a card or credential, the EDCD processes the data locally using its enhanced onboard capabilities, resulting in near-instant door response. This reduces delays at the door, which is especially important in high-traffic areas where slow response can cause congestion or user frustration.

Improved communications speed refers to how efficiently the EDCD exchanges data with other Millennium devices and the Site Control Unit (SCU or ESCU) over the RS-485 network. Faster communication allows status updates, alarm events, and transaction logs to be transmitted more quickly and reliably. This leads to more accurate real-time monitoring, quicker alarm reporting, and smoother system operation, even in larger installations with many connected controllers.
