Alert Buzzer
An alert buzzer is physically located in the LCD monitor.
The buzzer is connected to one of the following types of discrete outputs to
the LCD monitor:

PCIO

Basic Control Panel

Labjack

Serial Port
The buzzer will sound three beeps every 8.5 seconds when an
unacknowledged Alarm is active. The buzzer will sound two beeps every
60 seconds when an unacknowledged Warning is active. An
unacknowledged Caution will not activate the buzzer.
The buzzer can be temporarily muted by clicking on the icon to
the right of the Alert Status Indicator. When the buzzer is muted a
white diagonal line appears through the icon. To re-enable the
buzzer click on the icon again, the white line is removed.
The length of time that the buzzer is muted is defined in Mute Settings and
can be set to between one minute and 999 minutes. The system will
automatically re-enable the buzzer once the mute length period has
elapsed. The mute length may also be set to Unlimited, if Unlimited is
selected the buzzer is permanently muted when the buzzer icon is clicked.
The mute does not prevent the buzzer sounding if an emergency
alarm is generated, e.g. Backup Navigator Alarm.
