Hytronik HIR01/FM Flush Mount Passive PIR Motion Sensor for use with HC438V or HCD438

The Hytronik HIR01/FM is a flush mountable detached Passive Infrared (PIR) sensor head designed for integration with Hytronik power bases (HC438V or HCD438) to enable motion detection and daylight harvesting (constant lux control). It has a compact form factor suitable for mounting in luminaires or ceiling tiles where space is constrained.

Key Specifications

• Operating Voltage: 5V DC.
• Detection Principle: Passive Infrared (PIR).
• Detection Range: Maximum 8m x 5m (Diameter x Height).
• Detection Angle: 30° to 150°.
• Mounting Height: Maximum 5m.
• Connectivity: Integrated cable with an RJ12 connector for "plug-and-play" interface with the main controller body.

Functional Capabilities

• While the HIR01/FM acts as the detection interface, it enables the following system functions when paired with a compatible driver:
• Daylight Harvesting: Continuous monitoring of ambient light to calculate required artificial light output for a constant lux target.
• Tri-Level Control: Supports hold-time, stand-by period, and stand-by dimming levels (10%–50%).
• Environmental Rating: IP20 for indoor use, with an operating temperature range of -20°C to +55°C.
