I don't know about the clicking sounds... Maybe someone else can advise to that. However, the AGS will start the generator at whatever you have it set at. Also, you should here an annoying periodic beep if the battery runs to low for the refrigerator.
My AGS controller is on the ceiling in one of my basement compartments. You have to set the time off day, hours you do not want the generator to run and the battery level when you want it to kick in.
