Pass & Seymour CI355 Wattstopper PIR Low-Profile Ceiling Occupancy Sensor, 360°, 1200 Sq. Ft.

Pass & Seymour CI355 Wattstopper PIR Low-Profile Ceiling Occupancy Sensor

The Pass & Seymour CI355 is a Wattstopper passive infrared (PIR) ceiling mount occupancy sensor built for low-profile installation on 100-347 voltage systems. It delivers 360° detection coverage across up to 1200 sq. ft., making it well suited for open offices, classrooms, and commercial spaces where reliable occupancy-based lighting control is required. Detection Signature Processing filters out false triggers and provides immunity to RFI and EMI interference for dependable, consistent performance.

Key Features

• Coverage Area: 360° passive infrared detection pattern covers up to 1200 sq. ft. for whole-room occupancy sensing.
• Voltage Range: Rated for 100-347V systems, supporting a wide range of commercial installations.
• Detection Signature Processing: Eliminates false triggers and provides immunity to RFI and EMI for consistent operation.
• Built-In Light Level Sensor: Simple one-step set-up streamlines photocell-based commissioning.
• LED Occupancy Indicator: Visible LED confirms when occupancy is detected for easy verification during setup and testing.
• Walk-Through Mode: Automatically turns lights off 3 minutes after the area is initially occupied, ideal for brief visits such as mail delivery.
• Zero-Crossing Switching: Extends relay life by switching at the zero-crossing point of the AC waveform.
• DIP Switch Adjustments & Clip Mounting: DIP switches simplify sensor adjustments, while the clip mounting system makes ceiling tile installation simple.
