5. Installation
5.1 Ensure the mains supply is switched off and the
circuit supply fuses are removed or the circuit
breaker turned OFF (See image 1).
• A moving human body needs to cross/enter
one of these zones to activate the PIR sensor.
The best all-round coverage is achieved with
the floodlight mounted at the optimum height
of 2.5 metres. See image B.
• Careful positioning of the PIR sensor will be required
to ensure optimum performance.
• The PIR sensor is more sensitive to movement ACROSS
its field of vision than to movement directly TOWARDS
(See image C). Therefore position the floodlight so that
its PIR sensor looks ACROSS the likely approach path.
• Avoid positioning the floodlight where there are any
sources of heat in the detection area of its PIR sensor
(extractor fans, tumble dryer exhausts etc.) including
opposite any other light sources such as other
security floodlights.
• Reflective surfaces (i.e. pools of water or white painted walls) and overhanging
branches may cause false activation under extreme conditions.
• During extreme weather conditions the PIR sensor may exhibit unusual
behaviour. This does not indicate a fault with the product. Once normal
weather conditions return, the PIR sensor will resume normal operation.
