Lens G/L can be rotated to change the 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 40/50 ft. (12/15m) 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.
NOTE:
IR-TEC's TRANS and OS-NET PIR based Occupancy 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.
