FSP-Lx Lens Modules for FSP-2xx Series PIR Occupancy Sensors
Lens Coverage Guide
No: 24226 – 08/16 rev. 1
Catalog Number: FSP-L2/FSP-L3/FSP-L7
Country of Origin: Made in China
SPECIFICATIONS
Operating Temperature- .................... 40° to 167°F (-40° to 75°C
IP Rating when mounted to outdoor rated fixture ................IP-66
DESCRIPTION AND OPERATION
The FSP-2xx occupancy sensor is 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 the desired operational features. The Lens is selected based on the
coverage desired for the sensor application.
Lens modules are IP-66 rated when combined with an FSP-2xx sensor mounted to an outdoor rated fixture.
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.
The FSP-L2, FSP-L3, and FSP-L7 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.
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.
