The Wattstopper CI-305 is a PIR low-voltage ceiling occupancy sensor operating at 24VDC, 9mA with 360 coverage up to 1,200 ft, designed for center-mount installation in open offices, classrooms, and large commercial zones. The 9mA current draw enables higher sensor-per-panel density compared to 20mA alternatives, making it cost-effective for multi-zone installations with shared control infrastructure. It integrates with Wattstopper low-voltage panels to deliver automatic occupancy-based lighting control across wide-area commercial spaces.
