Typical Applications

• Open Offices & Conference Rooms: PIR line-of-sight detection is ideal for open-plan layouts with clear sightlines — auto-dims on departure without controller hardware.
• Classrooms: Consistent occupancy detection across desk zones; DLC Premium (S-6GLFQT) rebates support large-scale school retrofits.
• Healthcare Exam Rooms: CRI 85–87 supports clinical accuracy; PIR sensor reduces standby energy between patient visits.
• Private Offices: Single-occupant PIR detection reliably captures desk-level movement in enclosed 1×4 grid spaces.
• Retail Stockrooms & Storage: Automatic shutoff in low-traffic areas reduces energy waste without manual switching.
• Government & Institutional Buildings: DLC Premium certification plus integrated occupancy control satisfies energy code and rebate requirements simultaneously.
