Determines the timeout period in seconds for silencing an alarm after the user acknowledges any of the alarms using the Tab_Style templates. After an alarm is silenced, if any higher priority alarms occur, alarm sound will playback again.
The user can silence alarm explicitly using the silence alarm icon / command on the templates. Alarm silence settings set this way take precedence over the alarm silence effect due to alarm acknowledgment.
Note: This parameter is available only to projects based on Tab_Style templates.
Default Value: 0 (silence alarm indefinitely until all alarms are acknowledged)
