DANGER
Risk of serious damage to property and per-
sonal injury, e.g. from fire or electric shock,
due to incorrect electrical installation.
Safe electrical installation can only be ensured if
the person in question can prove basic knowl-
edge in the following areas:
• Connecting to installation networks
• Connecting several electrical devices
• Laying electric cables
• Outdoor electrical installation
These skills and experience are normally only
possessed by skilled professionals who are
trained in the field of electrical installation technol-
ogy. If these minimum requirements are not met
or are disregarded in any way, you will be solely li-
able for any damage to property or personal inju-
ry.
The ARGUS 220 (referred to below as the ARGUS) is a
movement detector for indoor and outdoor installation.
The ARGUS registers moving sources of heat within its
range, e.g. people, and switches the loads connected
whenever it detects a movement. This could include:
– ohmic loads (e.g. 230 V incandescent and halogen
lamps)
– inductive loads (e.g. low-voltage halogen lamps
with inductive transformer)
– capacitive loads (e.g. electronic transformers)
Surface monitoring of 220° for larger house fronts and ar-
eas of the house (max. range of 16 m) is combined with
a 360° short-range zone with a radius of approx. 4 m.
The operating elements for setting the brightness thresh-
old, switching duration and sensitivity are located under
the cover plate for protection.
The ARGUS can be mounted on the wall or ceiling and
also on to corners or fixed pipes with the mounting
bracket (art. no. 5652x) which is available as an acces-
sory.
The integrated functional display lights up when move-
ment is detected and thus simplifies the alignment of the
device at the installation site.

ARGUS introduction
en
The area of detection can be adapted to the local condi-
tions due to the horizontally, vertically and axially adjust-
able sensor head. You can also block unwanted zones or
sources of interference (e.g. trees) from the area of de-
tection using the masking segments provided.
The device is fitted with a light sensor whose brightness
threshold can be set between approx. 3 and 1000 lux.
|
The ARGUS is not suitable for use as a compo-
nent of an alarm system since it is supplied from
the mains and will switch the connected alarm
whenever the mains supply fails and recovers, re-
gardless of whether or not a movement is detect-
ed (false alarm).
Movement detectors switch on as soon as they detect a
moving heat source. This can be a person, but also
trees, cars or differences in temperature in windows. In
order to avoid false alarms, the chosen installation site
should be such that undesired heat sources cannot be
detected.
Undesired sources of heat could include the following:
• moving trees, shrubbery etc. with a temperature that
differs from that of their surroundings.
• windows where the influence of sunlight and clouds
could cause rapid changes in temperature.
• larger heat sources (e.g. cars), that are detected
through windows.
• insects moving across the lens.
• small animals.
• rooms flooded with light where the light is reflected on
objects (e.g. the floor), which can be the cause of rapid
changes in temperature.

Explanation of the symbols used
When selecting a suitable installation site, you should
take a number of factors into account so that the move-
ment detector operates optimally.
|
The following figure shows the ranges of the AR-
GUS at average temperature conditions and a
mounting height of 2.5 m. The range of a move-
ment detector can vary greatly depending on the
temperature.
Inner security zone A: Angle of detection 360° over
a radius of approx. 4 m.
Middle security zone B: Angle of detection 220°
with an area of detection of approx. 9 m x 18 m.
Outer security zone C: Angle of detection 220° with
an area of detection of approx. 16 m x 28 m.

Mounting height D: 2-3 m. For optimum monitoring,
we recommend a height of 2.5 m on a solid and even
base.
Minimum distance E to sources of optical interfer-
ence: 5 m If necessary, use the segments supplied to
shade the device.
Minimum distance F between luminaire and move-
ment detector: 5 m. If this distance cannot be
achieved, you can use the segments provided to
"mask" the light source from the area of detection.
If possible, install the movement detector sideways to the
direction of movement.
To avoid the connected load being switched on due to
environmental influences, the ARGUS should be in-
stalled so that it is protected against rain and direct sun-
light. A raindrop running over the lens, for example, can
activate the movement detector.

If you wish to attach several movement detectors, install
them so that the detection areas of the individual move-
ment detectors intersect each other.

Installing the ARGUS on the ceiling
In order to install the ARGUS on the ceiling, you must ro-
tate the sensor head. Change the direction of rotation
once you have reached the end stops.
1 Turn the sensor head upwards as far as it will go.
2 Turn the sensor head clockwise as far as it will go.
3 Align the sensor head.

CAUTION
If not installed correctly, the device can be
damaged by condensation.
In the case of sloping ceilings, install the device
so that spherical head is pointing down and al-
ways at an angle of 15° - 90°. When the spherical
head points downwards, any water from conden-
sation could run down the device.
|
Type of protection IP 55 cannot be guaranteed if
the mounting bracket is not 15° - 90°.
