149-101966 - EDCD SPEC SHEET
The Enhanced Door Control Device (149-101966 – EDCD) is a high-performance. Single-door controller designed for use with Millennium. It supports a wide range of reader technologies and provides reliable. Standalone operation to ensure continuous access systems even during network or server communication failures.
Features
Stores up to 60,000 cardholders locally
2,000-transaction history buffer for offline operation
RS-485 multi-drop communication with Millennium devices
Supports multiple reader technologies (Wiegand 0–256 bit, Magstripe ABA/ISO Track 2, Clock & Data, Marlock)
Two programmable Form C relays rated at 10A @ 24 VDC
Monitors up to 7 alarm inputs (4 supervised, 3 normally closed)
Benefits
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.

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.
