Maintenance Windows
Maintenance Windows in IO are used to suppress alarm notifications during specified time periods. Maintenance Windows are designed to reduce the number of false alarm notifications generated during known periods of abnormal activity. The intention of the Maintenance Windows feature is to increase the reliability of alarm notifications.
