Event history

All alarms and faults are stored in the event history. The event
history shows all events that have occurred. Actions performed
on the panel are also displayed (e.g. acknowledgement of an
alarm/fault). When the event memory is full (see section 3.2),
the First In – First Out (FIFO) principle is applied so that the
oldest events are deleted first.
The event history can be viewed in this tab. The "PgUp" and
"PgDn" buttons can be used to jump up or down in the view.
The "Prev" and "Next" buttons move the marker up or down
one line.
The red lines represent the trigger time of the event.
A yellow line appears when an event has elapsed without
confirmation.
The green line appears when the event has been confirmed.
The "Horn" button appears when alarms are currently present.
Touching the button confirms the alarms and turns off the horn
until another alarm condition is present.
