Figure 75 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 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.

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.
Consequently, alarm boxes permit configuring the following parameters:
 Trigger: defines the value that will trigger the alarm (“0” or “1”; it is “1” by
default), i.e., the value that, when received through [Pn][Bi] Alarm
