Hytronik HCD402 Flush-mount DALI Daylight and Motion Sensor

The Hytronik HCD402 is a flush-mounted DALI daylight and motion sensor designed for integration into DALI lighting control systems. It functions by receiving commands from a DALI master to manage and group up to 64 luminaires, providing the ability to switch, dim, and report status back to the controller.

Core Functionality & Grouping

• Rotary Coding Switch: Features a 16-channel rotary switch for manual DALI group assignment (Groups 0–14 and Broadcast) without requiring a PC or DALI master.
• System Overwrite: Supports PC-based grouping, which can overwrite manual rotary settings and vice-versa.
• sensorDIM Technology: Incorporates "soft-on" and "soft-off" dimming for smoother transitions.

Technical Specifications

• Operating Voltage: 9.5 – 22.5V DC (standard DALI power supply)
• Input Current: ~10mA
• Microwave Frequency: 5.8GHz +/- 75MHz; < 0.05mW power 
• Detection Range: Max 12m (D) x 6m (H); 30°–150° angle 
• Mounting: Flush mount; Max height 6m; 76mm installation hole

Configurable Settings (DIP Switches)

• Detection Area: Adjustable between 50% and 100%
• Hold-time: 2s (Test) to 20 minutes.
