The Day-Brite CFI FCY-SENSOR is a field-installed microwave occupancy sensor designed specifically for the FCY Value High Bay luminaire series. Engineered for seamless integration, this sensor adds intelligent occupancy-based control to your existing FCY high bay fixtures without requiring a new luminaire — making it an efficient, cost-effective upgrade for warehouses, manufacturing floors, gymnasiums, and other large commercial or industrial spaces.
Microwave sensing technology provides reliable detection across wide areas, even in environments with obstructions or slow-moving occupants, ensuring lights activate when needed and shut off when spaces are vacant. The field-installed design allows for straightforward retrofitting by a qualified electrician, minimizing downtime and installation complexity. Backed by Day-Brite CFI’s reputation for durable, high-performance commercial lighting, the FCY-SENSOR helps reduce energy consumption and extend lamp life through smarter, demand-driven operation.
