A nearby old building caught my eye the other day. While riding around, looking for letters for my urban alphabet, I noticed an odd looking fixture on it. Upon closer inspection I noticed it was an antique fire alarm system. I found another one on one of the other walls of the building. I wonder if this building was prone to going up in flames...thus the amount of fire alarms within a 30 foot radius.
This one is pretty awesome looking, but not nearly as awesome as...
This one has what appears to be the whole sprinkler system attached. Also, it was manufactured in Philadelphia, PA...about an hour from my current location.
