optimum height of 2.5m.
Careful positioning of the sensor will be required to
ensure optimum performance. See diagram A 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 (ie pools of water or white-painted
walls) and overhanging branches may cause false
activation under extreme conditions.
During extreme weather conditions the motion sensor
may exhibit unusual behaviour. This does not indicate
a fault with the sensor. Once normal weather conditions
return, the sensor will resume normal operation.
Installation
IMPORTANT
Switch off the electricity at the fuse box by removing the
relevant fuse or switching off
the circuit breaker before proceeding with the installation.
All fittings should be installed by competent person in
accordance with IEE Wiring Regulations (BS7671)
After choosing a suitable location (see previous section)
install the unit as follows:
The unit is suitable for connection to a 230 V ac 50Hz
electricity supply. It is suggested that 3-core round
flexible cable of 1 sq. mm gauge is used. An isolating
switch should be installed to switch the power to the unit
ON & OFF. This allows the sensor to be easily switched
