– Device: serial number and name (if available).
– Control input: name and device serial number (if available).
– Audio input: name and device serial number (if available).
– Audio output: name and device serial number (if available).
– Open Interface: IP‑address or, if available, TCP/IP device name, name of the user (if
available).
– Call station with authentication enabled: user ID (if available).
– Extra information based on event type (if applicable).

Fault events
The system controller stores the last 1000 fault events. The oldest fault event will be removed
from the non-volatile memory to free space for the new fault event.
Fault event status
Each fault event has a status:
Status Description
New The fault event is a new fault event. When a fault event occurs, it shall
initially be in the new state. Events can occur at any moment in an
operational system but only on devices that are enabled in the
configuration, unless specified otherwise.
All fault outputs * are activated (e.g. fault alarm buzzer, fault alarm
indicator). See
Multifunction power supply, page 53
and/or
Call station,
page 59
.
Acknowledged It is possible to acknowledge one or all events that are in the new state.
An event can only be acknowledged once. Once an event is
acknowledged the event shall enter the acknowledged state. If all faults
in the system have been acknowledged, all fault alarm buzzer outputs
are deactivated *.
Resolved The acknowledged fault event is resolved. Fault events shall
automatically resolve. For some fault events this is not possible and
these events shall have to be resolved manually (e.g. overload of an
amplifier). When the event is in the acknowledged state, and the error
situation that triggered the event is no longer present in the system,
the event shall automatically be resolved. An event can only be resolved
once. Once an event is resolved, the event shall enter the resolved
state.
