How to choose an installation site
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 300 , there should be a distance of at least
5 m between the ARGUS and the light. 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 300 sideways to
the direction of motion (Figure §).
The ARGUS 300 is in protection class IP 55 and is therefore also suitable
for outdoor use. To make sure that the lighting is not switched on by
environmental influences, you should ensure that the ARGUS 300 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".
¼
Risk of electrocution.
The ARGUS may only be installed and connected by skilled
electricians. Please observe the relevant regulations in your own
country.
½
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 300
To rotate the wall connection box:
The ARGUS 300 is supplied ready for mounting on the wall to the left of
a corner. To mount on a wall to the right of a corner (Figure %):
1 Press in the u-shaped release clip directly behind the sensor head
from underneath until it reaches the stop in both openings.
2 Remove the sensor head.
3 Rotate the wall bracket by 180° and then put the sensor head back
on.
To install the extension (554395/554399):
Figure &:
1 Press in the u-shaped release clip directly behind the sensor head
from underneath until it reaches the stop in both openings.
2 Remove the sensor head.
3 Place the two halves of the extension around the connection cable,
so that the screws are at the top. Then screw them together.
4 Refit the sensor head.
To open the hole for condensation water:
Depending on whether it is installed to the left or right of a corner, you
must open the lower of the two openings in the wall connection box
(Figure /):
1 Use a knife to cut open the rubberised condensation water opening
from behind.
See also the sticker inside the wall connection box.
Fitting the connection cable:
You can feed the connection cable from behind, from below or from
above, into the wall connection box:
1 Cut out the rubberised cable entry as required with a knife (Figure
().
2 Feed in the connection cable and mount the wall connection box
(Figure )).
