Manual refresh functionality is as per design for SOE and alarm summary. However, the button which refreshes events is TabAlarm_reloaddata(1).
Calling this function causes a manual refresh from the button.
The following is an example of cicode function which can be used to refresh alarm automatically as a simple work around.

FUNCTION MyAlarmList_Refresh(INT AN)
INT session = AlarmFilterEditOpen(AN);
IF (-1 <> session) THEN
AlarmFilterEditCommit(session);
AlarmFilterEditClose(session);
END
END

By default, the animation number of the main alarm list on the alarm templates of both Tab/SxW style libraries is 21.

The second step is to create an event that calls the function at periodic intervals and refreshed the alarm automatically.
See attached snapshot to call event and make sure you enable events from computer setup wizard else these events will fail to execute and observe automatic alarm refersh.
