Wattstopper CI PIR Ceiling Occupancy Sensor — Indoor & 360° CoverageThe Wattstopper CI355 is an indoor passive infrared (PIR) ceiling occupancy sensor designed to automatically control lighting based on room occupancy. This sensor, with its 360-degree coverage, is ideal for commercial applications. It operates within a voltage range of 100 to 347 VAC and supports a load rating of up to 800W. The CI355 does not require a neutral wire, simplifying installation.Key Features Detection Signature Processing: Minimizes false triggers and provides immunity to RFI and EMI. Walk-through Mode: Automatically turns lights off 3 minutes after initial occupancy detection. Light Level Sensor: Built-in sensor with simple, one-step setup for optimal energy savings. Zero-Crossing Circuitry: Extends relay life by reducing electrical stress. LED Indicator: Provides visual confirmation of occupancy detection. DIP Switch Adjustments: Simplifies sensor settings and adjustments. Clip Mounting System: Facilitates easy installation in ceiling tiles. RoHS Conformant: Meets environmental and safety standards. Warranty: Backed by a 5-year warranty for peace of mind. Construction & InterfaceThe CI355 features a flat, low-profile design that mounts seamlessly on the ceiling.
