Low Voltage PIR Low Profile Fixture Occupancy Sensor, 24V by Wattstopper

The FS-205 Low Voltage Passive Infrared (PIR) Fixture Sensor controls lighting based on occupancy. It is designed with a lowprofile, architecturally pleasing appearance to easily integrate into lighting fixtures or a customized housing. The modular plug-in system utilizes an RJ45 connector on a low-voltage 6-ft. cord for installation flexibility, and to quickly link to a remotemounted power pack.

Operation
When connected to an FS-PP Power Pack, the FS-205 sensor operates at 24 VDC to detect occupancy. Utilizing the latest PIR technology to detect the difference between heat emitted from the human body in motion and the background space, the FS sensor signals the FS-PP to close its relay and turn on the connected load. After the defined area is vacated and the adjustable time delay (30 seconds to 30 minutes) has elapsed, the sensor signals the FS-PP to open its relay and turn off the connected load.

Hold-off Daylighting
The hold-off daylighting light level feature provides additional energy savings. Once the lights turn off after the time delay has elapsed, this feature holds lighting off upon new occupancy if there is sufficient ambient light available (adjustable from 10-120 fc).

Applications
The FS-205 provides a 360° coverage pattern for up to 200 square feet when mounted at 8 feet. The sensor works well in a small office, cubicle or utility room. The FS-205 is little enough to be easily integrated into even the smallest housings when zonal control of direct/indirect fixtures is required.
