149 101179 ECD SPEC SHEET

The design of 149 101179 ECD (Elevator Control Device) connect to interface readers with an Elevator Control Unit (ECU). It enables effective management of elevator floor access based on authorized credentials.

That system enables key or card readers to communicate with the ECU, ensuring that only authorized users access designated floors. Serving as a communication and management interface within the Millennium access control. It utilizes supervised RS-485 communication for reliable and secure elevator operation.

149 101179 ECD device use

The use of Elevator Control Device control and restrict access to elevator floors as part of an access system.

Its primary function is to enable credential readers, such as card or optical key readers, to communicate with the system. It is usefull to communicate with the Elevator Control Unit (ECU), granting access to designated floors only to authorized users. This enhances security, prevents unauthorized access, and allows administrators to tailor access policies by user, area, or floor.

The ECD Functionalities

According to Millennium manuals, These systems control and restrict access to elevator floors as part of an access device system.. Its primary function is to enable credential readers, such as card or optical key readers, to communicate with the Elevator Control Unit (ECU), thereby granting access to designated floors exclusively to authorized users. This enhances security, prevents unauthorized access, and lets administrators tailor access policies by user, area, or floor.

Circuit protection

The ECD features integrated circuit protection to ensure safe and reliable operation. According to the specification sheet, the power input is protected against the following conditions:

Reverse polarity
Over-voltage
Transient surges

These protective features help prevent damage from wiring errors or electrical fluctuations, thereby enhancing the overall reliability of the elevator access system.

The Elevator Control Device is engineered to address key operational and security risks in elevator access control systems, including:

Unauthorized elevator access, by ensuring only users with valid credentials can enable floor selection through the ECU.
Electrical damage, with built-in protection against reverse polarity, over-voltage, and transient surges.
System tampering, using an integrated cover tamper switch to detect enclosure interference.
Communication failures, through supervised RS-485 communication between the 149 101179 ECD and ECU for reliable data transmission.
Operational instability, as the device is designed to operate within specified voltage, temperature, and humidity ranges. It is UL 294 listed for access control applications.

1 door control kit – The Millennium Ultra has a fully integrated 1-Door access system that combines robust hardware and proximity technology to design a safer access point for entry or exit.

ECD CHARACTERISTICS

The Elevator Control Device is designed to provide secure and reliable elevator access as part of the Millennium system. It enables communication between readers and the Elevator Control Unit (ECU), allowing authorized users to access specific floors only. The device supports multiple reader protocols, including Wiegand (0–50 bits), Magstripe ABA/ISO Track 2, Clock and Data, as well as Marlok optical key technology.. It communicates with the ECU using supervised RS-485 wiring to ensure dependable data transmission.

These system offers a scalable architecture, supporting up to 10 ECDs per SCU and up to 10,000 ECDs per system. It features built-in circuit protection against reverse polarity, over-voltage, and transient surges, as well as an integrated cover tamper switch for added security. With low power consumption, compact design, and UL 294 certification, the ECD is a robust solution for elevator access systems in commercial and high-security environments.

PREVENTIONS

The ECD prevents unauthorized access and operational issues in elevator access systems. By securely interfacing card or key readers with the Elevator Control Unit (ECU), it ensures that only authorized users can access designated floors. The device includes built-in protection against reverse polarity, over-voltage, and transient surges to prevent electrical damage. An integrated cover tamper switch detects and discourages unauthorized physical interference. Additionally, by leveraging supervised RS-485 communication, the system safeguards against data loss or communication failures, thereby ensuring reliable and secure elevator operation.

Use Cases

Corporate buildings:

Restricts access to specific floors based on employee, visitor, or area authorization.

Hospitals and healthcare facilities:

Controls access to critical floors such as ICUs, laboratories, as well as administrative areas.

Hotels:

Allows guests to access only the floors assigned to their rooms.

In all these scenarios, the ECD functions as the interface between access readers and the Elevator Control Unit (ECU), ensuring secure and reliable floor access systems.
