5. Selecting a Location
• The light controller has number of detection zones,
at various vertical and horizontal angles as shown
(see diagram A).
• A moving human body needs to cross/enter one
of these zones to activate the light controller.
The best all-round coverage is achieved with the
unit mounted at the optimum height of 2.5 metres.
• Careful positioning of the light controller will be
required to ensure optimum performance (see
diagram A detailing detection range and direction).
• The light controller is more sensitive to movement
ACROSS its field of vision than to movement
directly TOWARDS (see diagram B). Therefore
position the unit so that the light controller looks
ACROSS the likely approach path.
• Avoid positioning the light controller where
there are any sources of heat in the detection
area (extractor fans, tumble dryer exhausts etc.)
including opposite any other light sources such
as other security lights.
• Reflective surfaces (i.e. pools of water or white
painted walls) and overhanging branches may
cause false activation under extreme conditions.
