Holy crap! I was in the middle of burning a disc and my smoke alarm went off. It's EXTREMELY loud. It woke up my neighbour who is across the hall and another neighbour who was beside me but there's a stairwell in between us. I'm sure my other neighbour beside me woke up. It kept going off every 10 minutes or so for 5 minutes at a time. I phoned the d.o.d. at 6am and she came down and ended up phoning security since she didn't know what to do. They came and just disconnected it. I put in a request for a repair to housing for them to come replace the battery. Anyways, I'm going to sleep now.
