Hi, I'm at home and my scantronics 9200 is going off every 30 minutes. It's not really going off off. It's crackling through the internal alarm sound system and its beeping a few times. Then stops. Any ideas what is wrong with it? If I were to unplug the mains fuse to the alarm would it just go off using the battery. Help, can't sleep, but also can't do anything without landlord permission and they can't be contacted until tomorrow.
