Alert Trigger on Alert count

I am looking to create an alert if there are 3 triggered alerts instances of a specific AlertObjectID in the last 10 mins. 

I have working SWQL to give me a count but I seek suggestions on setting the Alert. 

Thanks, 
Sean

SELECT Count(Message) as AlertCount
FROM Orion.AlertHistory a
WHERE EventType=0
AND MINUTEDIFF(TimeStamp, GETDATE()) <=10
AND (a.AlertObjectID = '247821')
