DESCRIPTION AND OPERATION
The FS-305 and FS-355 occupancy sensors are modular, consisting of two parts, a Sensor Module and a Lens. The Sensor
Module is selected according to the type of power available in the installation and desired operational features. The Lens is
selected based on the coverage desired for the sensor application.
Sensors must directly “see” motion of an occupant to detect them, so careful consideration must be given to sensor
placement. Avoid placing the sensor where shelving or other obstructions may block the sensor’s line of sight.
FS-L2W, FS-L3W, FS-L4W, and FS-L6 have multi-cell, multi-tier Fresnel lenses with a 360° view. This document describes
the coverage patterns available with each lens. Coverages shown in the diagrams are maximum, measured in linear feet. They
represent coverage for full-step walking motion, with no barriers or obstacles.
Note: The FS-L2W, FS-L3W, and FS-L4W are wet rated. The FS-L6 is not.
Passive Infrared Sensing in Warehouses
Warehouses can have ambient temperature variations that may affect sensor detection and coverage areas. High
temperatures at the covered area (above 89-92°F) reduce the detection zone of the sensor. Consider adding more sensors if
the ambient temperatures are expected to be high. Additionally, high floor level temperature may require larger movement for
detection. In some cases, sensors mounted above 40’ may only detect large heat signatures such as forklift trucks.
See the Sensor Module Installation Instructions for a complete description of the assembled unit installation, wiring, and
safety information.
FS-L2W: 360° Coverage
The FS-L2W is designed for mounting at heights between
8’ to 12’. It provides a 48’ diameter coverage area when
mounted at a height of 8’, or a 72’ diameter coverage area
at 12’.
