response to movement in the detection zone. The light
then returns to the basic light level (approx. 25%).
P3 User-friendly economy programme
– Soft light start + basic light level until the middle of
the night
– Basic light level ON from twilight setting selected
until the middle of the night
How does the user-friendly economy programme
work?
The sensor-switched light does not have an integrated
clock. The middle of the night is only determined on the
basis of the length of darkness phases. To work per-
fectly, therefore, it is important for the sensor-switched
light to be permanently connected to the power supply
during this period. During the first night (calibration
phase) basic light level remains activated throughout
the night. The values are saved even in the event of a
mains power failure. We do not recommend interrupting
the power supply during the programme. As the values
are determined over several nights, the sensor-switched
light should, in the event of any fault occurring, be
monitored over several nights to ascertain whether the
switch-off time moves towards midnight.
P4 Nightmatic programme
– Soft light start, no basic light level, no movement
evaluation
– Switches ON at 100% if the light level falls below the
level set
Note: if the light has a house number panel it switches
ON in all four programmes when the level of light falls
below the twilight setting.
Twilight setting (controller
The chosen response threshold can be infinitely varied
from approx. 2 to 1000 lux.

– Control dial set to
To adjust the detection zone in daylight operation, the
control dial must be set to
Time setting (controller
The light's ON time can be set to any period from
approx. 5 seconds to a maximum of 15 minutes. Any
movement detected before this time elapses will restart
the timer.
Manual override function
If a mains switch is installed in the mains supply lead,
the following functions are available in addition to
simply switching light ON and OFF:
Sensor operation
1) Switch light ON (when light is OFF):
Switch OFF and ON once.
Light stays ON for the period selected.

2) Switch light OFF (when light is ON):
Switch OFF and ON once.
Light goes out or switches to sensor operation.
Manual override (Fig.
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 automatically to sensor operation (red LED off).
2) Deactivate manual override:
Switch OFF and ON once. Light goes out or switches
to sensor operation.
Important:
Switching must take place within 0.2 to 1 second.
Adjusting the detection zone (Fig.
The detection zone can be limited to suit requirements.
The shrouds supplied with the unit can be used to
mask out as many lens segments as you wish. This
prevents the light from being activated unintentionally,
e.g. by cars, passersby etc., and allows you to target
danger spots. The shrouds can be cut along the
grooved vertical divisions. Then you simply clip them
onto the lens.

7. Maintenance and care

The product requires no maintenance.
The light can be cleaned with a damp cloth (without
detergents) if dirty.
Important note: the control gear cannot be replaced.
