OVERVIEW
The LRD-309S and ON-LRD-309S sensors feature with interchangeable lens
options. Each lens provides different sensing coverage which varies with the actual
mounting height.
The specified detection coverage and mounting height of each lens are based on the
test result of human motion walking across the detection zones. The actual coverage
may be reduced if the motion is moving toward or away the sensor. High ambient
temperature (above 28°C/82°F) could reduce the coverage of PIR sensor. If ambient
temperature at the covered area are expected to be high sometimes, consider
adding more sensors or reduce the mounting height, if possible.
The followings are all available lens options and their respective detection patterns at
printing time. For details of latest lens options available, please visit www.irtec.com.

This product may be covered by one or more U.S. patents or patent applications.
Please visit www.irtec.com for more information.
Lens g/l can be rotated to change its direction of coverage. Its 3X/6X height
coverage refers only to the total length, the width of coverage will vary with the
mounting height (see table of Lens g/l section). This lens is not IP-66 rated.
Lens c/g may be mounted up to 12/15 m (40/50 ft.) or higher at the area, providing
with large moving object such as forklift trucks. Before installing all sensors, please
ensure that the sensor can have optimal detection at desired height.
