Hytronik HIM39RF-SUM Wireless Ceiling Mountable High Bay DALI Motion Sensor

The Hytronik HIM39/RF-SUM is a surface (ceiling) mountable, high-bay dual-technology motion sensor designed for independent DALI control with integrated RF wireless mesh capabilities. It utilises a "Dual Sense" architecture, combining High Frequency (5.8GHz microwave) and PIR technologies to minimise false triggers while maintaining high sensitivity in a warehouse environment. Technical Specifications • Operating Voltage: 120–277VAC, 50/60Hz. • Control Interface: DALI output, supporting a maximum of 20 devices (max. 40mA). • Dual-Tech Modes: 4 configurable modes (PIR only, HF only, HF+PIR for false-trigger immunity, or HF/PIR for maximum detection area). • Detection Range: Maximum 18m (diameter) x 15m (height). • RF Transmission: 868MHz (FSK); range up to 30m indoors and 50m outdoors. • Environmental Protection: IP65 rated; operating temperature -20°C to +50°C Key Functionalities • Tri-Level Control: Supports a 100%  dimmed light  off sequence with selectable hold-times and stand-by periods. • Intelligent Photocell: Built-in daylight sensor that can switch off fixtures even during occupancy if natural light exceeds the programmed threshold for >5 minutes. • RF Grouping: Rapid commissioning via a 15-channel rotary switch or remote control HRC-11 (sold separately) for master/slave mesh configurations. • Mounting Options: Surface (ceiling) mountable. Wiring Configuration • The HIM39/RF serves as both a transceiver and a controller. It features a 4-wire connection to the DALI bus: • Mains: L, N (Brown, Blue)13. • DALI Bus: DALI+, DALI- (Yellow, Black)
