Thank you for contacting Syncfusion Support.
We have checked your reported requirement in our side. In our current implementation we don't have support for alarm based appointments. So we will consider as a feature request. So could you please confirm some specific details about your requirement, that will help us to define the feature.
Need to create reminder event in source level. It will get invoke when the start time will meet the current time.
Meanwhile we can be achieved the your requirement by creating a timer in sample level with timespan (for ex: 30 minutes), so at regular interval, it can check with the events start time from the appointments collection (which is binded) with the control.
Where are alarm or notification are to be handled in application level, for that we can suggest you to refer some blogs related to that.
