Standby
sensitivity
on
day/night
The
presence
detector
is
in
the
standby
mode
if
no
presence
was
detected
and
so
the
detector
is
switched
off.
If
the
day/night
object
is
active,
different
sensitivies
can
be
adjusted
for
the
day
and
the
night
mode.
A
lower
sensitivity
prevents
faulty
activations.
Presence
active
sensitivity
In
order
that
the
presence
detector
detects
every
movement
at
the
presence
mode
(=
detector
has
detected
a
motion
and
is
switched
on),
a
higher
sensitivity
can
be
adjusted
for
this
case.
The
following
figure
demonstrates
the
motion
sensitivity:
Figure
7:
Motion
sensitivity
The
upper
figure
shows
the
effect
of
the
different
settings
to
the
motion
sensitivity.
A
lower
motion
sensitivity
causes
a
larger
range
of
tolerance.
A
higher
motion
sensitivity
causes
a
smaller
range
of
tolerance.
Every
infrared
signal
(dotted
line),
which
is
out
of
the
range
of
tolerance
is
detected
as
motion.
For
configuring
the
detector
in
a
way
that
small
signals,
e.g.
passing
a
door,
not
cause
an
activation,
the
sensitivity
must
be
set
to
a
ower
value,
so
the
range
of
tolerance
is
set
to
a
higher
value.
