I'm currently writing a fanfic based in the TF: ANIMATED universe, and I'm still trying to catch up with all the niggling little details of the characters and settings, right down to watching the episodes one-by-one. But I haven't found a straight answer to the title of this thread yet. Whenever Decepticon activity occurred in Detroit, how would the Autobots be alerted to their presence? Through Teletran-1? Apologies if there's a stupidly obvious answer given in a scene while I was in the bathroom, but as I said, I'm still getting my bearings in this corner of the TF franchise.
