Overview

The NSI Industries COS-L is a ceiling-mounted Passive Infrared (PIR) occupancy sensor engineered for energy-efficient lighting control in large office areas, meeting rooms, classrooms, and storage spaces. This 24VDC device delivers 1200 sq ft coverage with a factory-set 10-minute time delay, adjustable from 5 to 30 minutes in six steps. The sensor features three selectable modes: Automatic On/Off for standard operation, Walk Through for energy savings in transient spaces, and Test mode for installation verification. Customizable via button-push programming, the COS-L allows users to optimize sensitivity, select trigger technologies (PIR or ultrasonic), and enable a 2-minute flash warning before shutdown. Compatible with TRP-24I or TRP-24B power packs (sold separately), it supports up to six Tork occupancy sensors. Mounting options include direct ceiling/box installation or optional pendant/side mounting with a ½" threaded nipple adapter. Operating from 32°F to 131°F (0°C to 55°C), the COS-L is backed by a 5-year warranty.
