3.3 Light measurement
● The ECO-IR presence detector is designed for use with fluorescent
lamps. It is particularly suitable for switching electronic ballasts. Incande-
scent or halogen lamps may interfere with the operation of the detector.
● With indirect lighting, ensure that the light from these lamps is not di-
rected at the detector, as this would affect the daylight measurement.
● When using suspended lighting it is advisable to integrate the detector
directly into the lamps or to keep a sufficient lateral gap.
