You can also turn off the audible alarm manually through StorCon or StorCon+. If you use these management tools to silence the alarm, it will only be disabled for the current event and will be ready to sound again at the next event. Silencing the Audible Alarm in StorCon In StorCon, under Advanced Setup > Configure Controller, press to silence alarm. Note: The option is only available if the alarm has been activated. 18 Hardware Installation and User's Guide
