Can I install a 754HB2/180/60 sensor light anywhere towards requested detection area



No, you need to avoid positioning the sensor where there are any sources of heat in the detection area (extractor fans, tumble dryer exhausts, etc.)
including ay other light sources such as other security lighting; and reflective surfaces (i.e. pools of water or white painted walls) and overhanging
branches may cause false activation under extreme conditions.
