The
function
of
the
alarms
is
identical
for
every
of
the
three
alarm
types.
For
every
of
the
three
alarms
a
periodic
observation
can
be
activated
(have
a
look
at
4.8.3).
Furthermore
an
action
for
the
release
of
each
alarm
can
be
set.
Here,
the
user
has
3
opportunities:
On
the
one
hand
the
shutter
actuator
can
drive
the
channel
to
the
top
or
to
the
bottom,
when
the
alarm
is
activated.
On
the
other
hand
the
shutter
actuator
can
react
with
the
setting
“no
action”.
At
this
setting,
the
channel
stays
in
its
actual
position.
A
movement
of
this
channel
is
not
possible
as
long
as
the
alarm
is
activated.
Also
after
the
reset
of
the
alarms,
the
shutter
actuator
can
perform
predetermined
functions.
These
are
descripted
at
4.8.5.
Please
note,
that
the
communication
objects
of
the
alarms
shall
always
be
connected
to
group
addresses;
otherwise
there
is
no
opportunity
to
receipt
the
alarms.
If
an
alarm
is
activated
because
of
its
periodic
observation,
which
is
not
connected
to
a
group
address,
you
will
only
be
able
to
receipt
it
by
using
the
ETS
‐
Software!
4.8.3
Periodic
observation
The
periodic
observation
of
the
alarm
function
can
be
activated
for
every
of
the
three
alarms
separately.
The
dynamic
range
extends
from
0
to
120min,
whereby
the
setting
0
min
sets
the
periodic
observation
off.
The
communication
object
for
the
respectively
alarm
must
get
a
signal
during
the
parameterized
time,
otherwise
the
alarm
causes
automatically.
There
are
settings
at
KNX
weather
stations,
in
which
clearances
the
periodic
sending
shall
follow.
The
time
for
the
periodic
sending
shall
be
always
set
less
than
the
observation
time
to
avoid
an
unwittingly
cause
of
the
alarm.
You
can
get
sure
that
a
weather
sensor
works
properly,
by
using
the
periodic
observation.
If
a
signal
is
absent,
because
of
a
failure
of
the
weather
station
or
a
wire
break,
the
shutter
actuator
will
trigger
the
alarm
after
the
expiration
of
the
observation
time.
The
following
illustration
shows
the
setting
options
for
the
periodic
observation:

Action
at
reset
of
alarms/removal
For
every
channel
an
action
at
the
reset/removal
of
the
alarm
can
be
parameterized.
This
parameter
operates
to
all
alarms
of
the
selected
channel.
The
dynamic
range
of
this
parameter
is
shown
at
the
following

Action
at
reset
of
alarms
The
user
has
4
different
setting
options
for
the
parameter
“action
at
reset
of
the
alarms”,
which
the
shutter
actuator
can
conduct
for
this
channel.
By
using
the
setting
“no
action”
the
channel
stays
in
its
position,
which
he
had
during
the
active
alarm.
