Alarm (Box).
The intermitting exclamation means that the alarm is active and unconfirmed.
However, alarm boxes implement an additional binary object,
[Pn][Bi] Alarm
Confirmation
, intended for receiving the value “1” from the bus, which will be
interpreted as an acknowledgement of the alarm, thus making the icon
intermittence stop. Alternatively, the alarm can be acknowledged (and muted)
by touching on the “OK” button in the box itself, which will cause the sending
of the value “1” through the mentioned object.
The alarm will definitely become inactive once it has been confirmed and, in
addition, once the
[Pn][Bi] Alarm Trigger
object goes back to the “no alarm”
state (the order of these two events is irrelevant), after which the icon will
finally turn off.

Note
:
whenever an alarm gets activated, confirmed or deactivated, a “push”
notification is sent from Z41 to all mobile devices it may have been linked to
through the Z41 Remote application. Please refer to
ANNEX I. Controlling Z41
Remotely via IP
.
There is also the possibility of
periodically monitoring
the status of the
trigger object, for situations where this object is periodically received from the
bus. This will let Z41 automatically assume the alarm situation if the “no alarm”
value does not get sent through the trigger object after a certain time, for
example upon failures of the transmitter. The maximum time window can be
defined by parameter.
