How to choose an installation site
| Note: ARGUS is not suitable for use as a component of an alarm
system since it is supplied from the mains and will switch the
connected alarm whenever the mains supply fails and is
established again, regardless of whether or not a movement is
detected (false alarm).
How to choose an installation site
Figure „:
A Mounting height: beween 2 m and 3 m, optimal is 2.5 m, on a solid
and flat surface.
When using the radio module and installing on an outside wall,
make sure that ARGUS is not mounted at the height of the ceiling,
since this results in the radio signals being significantly dampened
and could mean that they do not reach the receiver. Further
information can be found in the Merten radio guideline.
B Distance to sources of optical interference: approx. 5–6 m
C If the luminaire to be switched is located within the area of
detection of ARGUS, there should be a distance of at least 5 m
between ARGUS and the luminaire. Mount the luminaire above
ARGUS, not below it. Otherwise, use the segments provided to
shade it (see the section "How to mask individual areas").
For optimum movement detection, mount ARGUS sideways to the
direction in which people walk (Figure §).
ARGUS has type of protection IP 55 and is therefore suitable for use in
outdoor areas as well. To make sure that the lighting is not switched on
by environmental influences, you should make sure that ARGUS is
sheltered from rain and direct sunlight (for example, raindrops running
down the lens could cause the movement detector to switch) (Figure
$).
Further information can be found in the "Merten Technical Information", in
the section "ARGUS movement detector".

Installing several ARGUS devices:
To ensure complete coverage, position the individual movement
detectors so that their detection areas overlap (Figure %).
Mounting ARGUS on the ceiling:
Figure &:
To mount on the ceiling, turn the sensor button as follows (change the
direction of rotation when you have turned it as far as the stop):
– Turn the sensor button upwards as far as it will go A.
– Turn the sensor button clockwise as far as it will go B.
– Align the sensor buttonC:

Mounting ARGUS at inner/outer corners or on fixed pipes.
Figure /: You can attach ARGUS to inner/outer corners or fixed pipes
using the Merten mounting bracket, art. no. 565291/..92/..93. The
connecting cable can be fed into the device from behind through the
mounting bracket.

Risk of electrocution
ARGUS may only be installed and connected by skilled electricians.
Please observe the relevant regulations in your own country.
Caution: If installation is not carried out correctly, water can
penetrate into ARGUS and damage it. Always mount ARGUS with
the spherical head pointing downwards.
Caution: If not installed correctly, ARGUS can be damaged by
condensation.
If the ceiling is inclined, always mount ARGUS with the sphere
facing downwards, so that condensation water can drain.
Mount ARGUS at an angle of inclination of between 15° and 90°;
otherwise, protection type IP 55 is not guaranteed.
