4. Selecting a Location
• Careful positioning of the sensor will be required to ensure optimum
performance.
• The best all-around coverage is achieved with the unit mounted
at the optimum height of 2.5 metres.
• The sensor is more sensitive to movement ACROSS its field of vision than to
movement directly TOWARDS it. Therefore position the unit so that the sensor
looks ACROSS the likely approach path.
• Reflective surfaces (i.e. white-painted walls) may cause false activation
under extreme conditions.
• 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.
• Install the sensor at least 3' away from fluorescent and HVAC ducts,
and at least 4' away from incandescent fixtures and HVAC diffusers.
