Fire Alarm FAIL

Bear me for a second here, this is a two parter and the first reader submission! Witnessed by reader Sarah at the Broad Street Line's Broad-Lombard station. She writes:

no, there's not much of a story: it's a fire alarm connected to, uh, nothing, at the broad and lombard broad street line station. also, if you look closely, you'll see the alarm itself isn't exactly present in its entirety.

sorry it's in two parts--caught it with my cell phone camera, so i had to make do.

but yeah--this sure does make ya feel safe, huh?

Now, to be fair, it is possible that these alarms operate on batteries or there is a second power line running directly into the concrete column to which it is attached, but come on, REALLY?
