Setup and Installation

Package Contents

• Dahua DEE1010B-S2 RS485 Relay Module
• Mounting Screws (if included)
• Quick Start Guide (refer to this manual for detailed instructions)

Mounting

The module is designed for surface mounting. Choose a secure, dry location near your access control station or the device it will control. Use appropriate screws to fix the module firmly to the desired surface.

Wiring Diagram and Connections

Refer to Figure 3 for a detailed view of the terminal labels. Ensure all connections are made securely and correctly to prevent damage to the module or connected devices.

1. Power Supply: Connect a +12V DC power source to the +12V and GND terminals. Ensure the power supply meets the module's requirements.
2. RS485 Communication: Connect the RS485 A and B lines from your access control station to the 485A and 485B terminals respectively. Maintain correct polarity.
3. Relay Outputs (for Lock/Alarm Control):
   • NC (Normally Closed): Connect to devices that require a closed circuit to operate when the relay is inactive.
   • NO (Normally Open): Connect to devices that require an open circuit to operate when the relay is inactive.
   • COM (Common): The common terminal for the relay.

   For example, to control an electric lock, connect the lock's power input to either NC or NO and the other end to COM, depending on the lock's operating mode (fail-safe or fail-secure).
4. Button Input: Connect an external exit button or similar trigger to the BUTTON and GND terminals.
5. Feedback Input: Connect a door sensor or similar feedback device to the FEEDBACK terminal and its corresponding ground.
6. Output Status Indicators (O POWER, O RUN, O UNLOCK): These terminals provide status outputs that can be connected to external indicators or monitoring systems.

After all connections are made, double-check wiring before applying power.

Operation

The Dahua DEE1010B-S2 module operates as an extension of your Dahua access control system. Once properly connected and configured within the main access controller's software, it will respond to commands received via the RS485 bus.

Relay Control

• The relays (NC/NO/COM) are typically controlled by the main access controller to trigger actions such as unlocking a door, activating an alarm, or controlling other connected devices.
• The specific configuration and mapping of relay outputs to events (e.g., valid card swipe, remote unlock command) are managed through the access control system's software interface.

Input Monitoring

• The BUTTON input allows for local control, such as an exit button to momentarily unlock a door.
• The FEEDBACK input can be used to monitor the status of a door (open/closed) or other sensors, providing real-time feedback to the access control system.

Status Indicators

The O POWER, O RUN, and O UNLOCK terminals provide electrical signals indicating the module's power status, operational status, and unlock events, respectively. These can be integrated with external LEDs or monitoring systems for visual or automated status checks.

Maintenance

The Dahua DEE1010B-S2 module is designed for low maintenance. Regular checks can help ensure its continued reliable operation.

• Cleaning: Periodically clean the exterior of the module with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Connection Check: Annually, or as needed, inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation.
• Environmental Conditions: Ensure the module is operating within its specified environmental conditions (temperature, humidity) to prevent premature failure.
• Firmware Updates: While the module itself typically does not require direct firmware updates, ensure your main access control system's firmware is up-to-date, as this can affect the module's performance and compatibility.
