Alarm
Boxes configured as alarms perform user warnings on anomalous events. For this
purpose, boxes of this type are related to a binary object (
[Pn][Bi] Alarm Trigger
) that
permits receiving alarm messages from the bus, thus making Z41 Pro / Lite / COM emit
a continuous beep while the screen light blinks. In addition, the screen will automatically
browse to the page containing the alarm box that has been triggered. After that moment,
pressing on the “Menu” button will interrupt the beeps and blinks although the box will
still show an intermitting icon, which means that the alarm is still active and unconfirmed.
Additionally, the icon of the page that contains the box will also show an exclamation.
Figure 121
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.
