Audible Alarm Operations
Whenever an error condition exists, the audible alarm automatically sounds until
all errors are corrected. You have the option of either muting or disabling the
alarm. These options establish the following conditions:
■ Disabling the audible alarm prevents it from sounding for any error condition.
■ Muting the alarm silences it for the existing condition, but any new condition
causes the alarm to sound.
Audible Alarm Patterns
The audible alarm sound pattern differs depending on the type of error condition.
Table 20 illustrates the duration and the approximate relationship of the alarm
patterns. The most severe, active error condition controls the alarm pattern.
Controlling the Audible Alarm
You can control the alarm with the pushbuttons. This process includes muting,
enabling, and disabling the alarm. When an error condition exists and the alarm
sounds, you can silence it in the following ways:
■ Correct all errors, silencing the alarm until a new error occurs.
■ Mute the alarm by pressing and holding the bottom pushbutton. The alarm
remains off until another error occurs, or until you enable (“unmute”) the
alarm. When a new error occurs, the alarm sounds and the pushbutton LED is
Off.
