Figure „:
A Mounting height: between 2 m and 3 m, optimal is 2.5 m, on a
solid and flat surface.
B Distance from sources of optical interference: approx. 5–6 m
C If the luminaire to be switched is located within the area of
detection of the ARGUS, there should be a distance of at least 5 m
between the ARGUS and the luminaire. Mount the luminaire
above the 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 the ARGUS sideways to the
direction of motion (Figure §).
The ARGUS has protection type 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 the ARGUS is
sheltered from rain and direct sunlight (for example, raindrops running
down the lens could cause the movement detector to be switched)
(Figure $).
Further information can be found in the "Merten Technical Information", in
the section "ARGUS movement detector".
How to mount the ARGUS
¼
Risk of electrocution.
The 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 the ARGUS and damage it. Always mount the
ARGUS with the spherical head pointing downwards.
How to mount the ARGUS
Installing several ARGUS devices:
To ensure complete coverage, position the individual movement
detectors so that their detection areas overlap (Figure %).
Mounting the ARGUS on the ceiling:
Figure &:
To mount on the ceiling, turn the sensor head as follows (change the
direction of rotation when you have turned it as far as the stop):
– Turn the sensor head upwards as far as it will go A.
– Turn the sensor head clockwise as far as it will go B.
– Align the sensor head C:

Mounting the ARGUS on inner/outer corners or on fixed pipes.
Figure /: You can attach the 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.
Mounting the ARGUS in wall connection boxes:
Figure (:
1 In order to lead the connecting cable into the back of the device from
above, attach the four spacers supplied to the wall-mounting bracket.

Caution: If not installed correctly, the ARGUS can be damaged by
condensation.
If the ceiling is inclined, always mount the ARGUS with the sphere
facing downwards, so that condensation water can drain.
Mount the ARGUS at an angle of inclination of between 15° and
90°; otherwise, protection type IP 55 is not guaranteed.
