Hey there. It's more of a stupid resident problem than anything else. (although this particular false alarm was triggered by many jack hammers working in the garage area) Most of the time it's people forgetting that they put something on the stove, it burns and smokes up their apartment. Then (this is the dumb part) they open their door to let the smoke out into the hallway where it triggers the main alarm.
Once management starting fining people $500 dollars for their stupidity in opening the doors instead of airing out the smokey apartment by opening their windows (and after countless notices and warnings) the incidences have stopped. (knock on wood)
