The Wattstopper CI-300-1 is a high-density PIR low-voltage ceiling occupancy sensor operating at 24VDC, 20mA with 360 coverage up to 500 ft, optimized for center-mount installation in smaller or high-partition commercial spaces such as private offices and workstations. The sensor automatically switches lighting on and off based on occupancy detection, integrating directly with Wattstopper low-voltage control panels. Its high-density detection pattern delivers reliable minor-motion sensing suitable for sedentary occupants in focused work environments.
