4. Selecting a Location
• The motion detector has number of detection zones, at various vertical
and horizontal angles as shown (see diagram “A”).
• The best all-round coverage is achieved with the unit mounted
at the optimum height of 2.5 metres.
• Careful positioning of the sensor will be required to ensure optimum
performance (see diagram “A” & “B” detailing detection range and direction).
• The sensor 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 sensor looks ACROSS the likely approach path.
• Avoid positioning the sensor 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) may cause
false activation under extreme conditions.
