Isn't the bell intended to be a general alarm no matter if units can go inside that building or not? It does not say "come home to me" but "go, look for shelter" I fdo agree that we should have a garrison of 1 to a lookout. It used to be the case in earlier versions of the game. The intent was to permanently occupy a gaia lookout and keep it (avoid decay). This has changed a while ago. Now you can claim a lokkout and it will not decay.  

What's this?: Maybe something that is not public?

We gave cretan arches a slight distinction due to their shields.  Also Peltasts vs regular javs.

Now that you say it, isn't that a bit weird? They don't garrison troops with the alarm. I'd only have it in all buildings that can garrison, and maybe add a garrison of 1 to the Lookout just as an excuse to have it there also.
