Indicates that the event is considered to be an alertable signal. Should be set to true if disposition_id = Alert among other dispositions, and/or risk_level_id or severity_id of the event is elevated. Not all control events will be alertable, for example if disposition_id = Exonerated or disposition_id = Allowed.
