Hytronik HIR24 Flush-mount DALI Daylight Harvesting PIR Motion Sensor

The Hytronik HIR24 is a flush-mount PIR motion sensor specifically designed for independent DALI daylight harvesting systems. It integrates motion detection with ambient light sensing to regulate DALI light output, maintaining constant lux levels through natural light replenishment.

Technical Specifications

• Operating Voltage: 220-240VAC 50/60Hz.
• Switched Power: Supports a maximum of 20 devices (up to 40mA).
• Power Consumption: Standby power is less than 1W.
• Environment: Rated IP20 with an operating temperature range of -20°C to +50°C.

Sensor & Detection Performance

• Detection Range: Provides a 360° detection angle with a maximum mounting height of 5m.
• Coverage: Achieves a detection area of 10m (diameter) when mounted at 3m height.
• Synchronization: Multiple HIR24 units can be linked via "SYNC" terminals to expand the detection area; if one sensor triggers, all connected units in the group activate.

Control & Configuration

• Operational Modes: Includes Daylight Harvesting, Manual Override (via push-switch), and Semi-auto Mode for absence detection.
• Programming: Features a built-in 16-channel rotary switch for fast scene selection.
• Remote Commissioning: Fully compatible with the HRC-11 remote control (sold separately) for adjusting detection range, daylight thresholds (50–500 Lux), hold-time (up to 30 min), and standby dimming levels.

Installation

• Mounting: Designed for ceiling flush mounting.
• Preparation: Requires a drill hole of 70mm in diameter.
• Dimensions: The unit features an 85mm diameter flange and a total depth of 73.3mm
