Underground Parking Lighting Control with Acti9 iCT+ and Argus 360

This document presents a lighting control solution for underground parking, using silent zero crossing contactors (Acti9 iCT+) and movement detectors (Argus 360) to automate lighting based on occupancy, with a manual override switch for maintenance. The system optimizes energy costs by providing light only when needed, enhances resident comfort through automatic activation, and ensures reliability by limiting LED inrush current.
