Below Alert height as people have said you would only go around for a red auto land light. If the cavalry alert comes on then you need to manually fly the go around or if you hit the ground when you go around then the autopilot will trip out due to TOGA+Ground condition sensed.
You would get a single chime below alert height if you had an engine failure for example and the capability on the FMA would downgrade but no triple click and you don't need to go around as you are below alert height and no red auto land light.
