Manual override function (Fig. 6.2)
If a mains switch is installed in the mains sup-
ply lead, the following functions are available in
addition to simply switching light ON and OFF:
Sensor operation mode
1) Switch light ON
switch OFF and ON once.
Light stays ON for the period selected.
2) Switch light OFF
switch OFF and ON once.
Light goes out or switches to sensor op-
eration.
Manual override
1) Activate manual override:
Switch OFF and ON twice. The light is
set to stay ON for 4 hours (red LED lights up
behind the lens). Then it returns automatical-
ly to sensor operation (red LED off).
2) Deactivate manual override:
Switch OFF and ON once. Light goes out or
switches to sensor operation.
Important:
The switch must be actuated in rapid succes-
sion (in the 0.5 – 1-second range).
Soft light start
The sensor-switched light features a soft light
start function. This means that when switched
on, the light does not switch directly to maxi-
mum output but gradually builds up brightness
to 100 % within the space of a second.
Brightness is also gradually reduced when the
light is switched OFF.
7. Precision adjustment using
shrouds
Shrouds may be used to define the detection
zone exactly as you require in order, for
example, to mask out neightbouring premises
or specifically target paths. The shrouds can be
divided or cut with a pair of scissors along the
vertical and horizontal grooves.
The shrouds can be then clipped into the top
channel around the centre of the lens. They are
fixed in place by fitting the cover. (Fig. 7.1)
• Sensor angle of coverage and reach without
shrouds (Fig. 7.2)
• Examples showing how to use shrouds for
reducing the angle of coverage and reach
(Fig. 7.3, 7.4)
8. Operation / maintenance
The sensor-switched light is suitable for switch-
ing ON light automatically. Weather conditions
may affect the way the sensor-switched light
performs. Strong gusts of wind, snow, rain or
hail may cause the light to come ON when it
is not wanted because the sensor is unable
to distinguish sudden changes of temperature
from sources of heat. The detector lens may
be cleaned with a damp cloth if it becomes
dirty (do not use cleaning agents).
9. Disposal
Electrical and electronic equipment, acces-
sories and packaging must be recycled in an
environmentally compatible manner.
Do not dispose of electrical and
electronic equipment as domestic
waste.
EU countries only:
Under the current European Directive on Waste
Electrical and Electronic Equipment and its
implementation in national law, electrical and
electronic equipment no longer suitable for use
must be collected separately and recycled in
an environmentally compatible manner.
