AVS Electronics BM60HP Mode D'emploi page 43

It is possible to install the system BM60HP also to protect
walls. In this case, the system of installation shown
in the drawing can be used, in order to avoid
false alarms caused by cats or birds. In
this case also, the height from
ground must be between 1 and
1,2 meters.
Because of ground
characteristics, it may
happen to have a very high
sensitivity in the centre of the
protected area and near the ground, E
because of special reflection of the ray.

It is also possible
to install the system
BM HP along a transited
street with transit; in this case,
it is necessary to keep a minimum
distance of 4 meters (for BM60HP)
or 10 meters (for BM120HP and
BM200HP) between the sight-line of the
couple and the area of transit of the cars.
In case a metal fence is placed between the
transit area and the area to be protected, detectors
must be kept at a minimum distance of 1 meter (for
BM60HP) or 5 meters (or BM120HP and BM200HP) from the
fence.
