Chapter 5: ARGUS
5.1 ARGUS movement detector, surface-mounted
INSTABUS ARGUS 220 Connect
Art. no. 6315 ..
Version 03/04 4

Movement detectors are not suitable for use as
components of an alarm system as defined by
the German insurance industry association VdS
(Verband der Sachversicherer). After a bus volta-
ge failure, the detectors may be triggered inde-
pendently of movements. This could in turn
trigger the alarm function.

Movement detectors can trigger false alarms if
the installation site has been chosen unfavou-
rably.
Movement detectors switch 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 can-
not be detected. Undesired sources of heat could in-
clude 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 th-
rough windows.
– insects running over 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.
How to install the ARGUS
1 Loosen the two screws and remove the wall con-
nection box from the device.
2 Mark the intended drill holes on the mounting sur-
face.
3 If you wish to insert a bus line from the top into the
back of the device, clip the four spacers supplied
