Deactivating Alarms
An alarm is deactivated automatically when the alarm state is reversed. E.g. if power is restored
after a PSU Failure alarm, or if audio is restored after an Input Silence alarm.
Deactivating Input Silence Alarms
An Input Silence alarm is activated when the configured audio and duration thresholds have
been breached. To recover from this alarm state the codec must detect input audio higher than
the failure threshold. When audio at this level is detected, the codec monitors input audio to
ensure it doesn't drop below the recovery threshold setting more than 5 times within the
nominated Input Silence duration time. The alarm is then deactivated automatically.
Alarm History
1. Open the HTML5 Toolbox Web-GUI and click Alarms, then click Alarm History to display a
record of all system alarms which have been raised.
Click the Purge alarm history button to clear all alarms from the Alarm History panel.
