I bought a fixer-upper house, which came with an alarm system. I know absolutely nothing about it, the realtor knows absolutely nothing about it (it was a foreclosure home), and the local company that serviced it has gone out of business. I am seriously considering ripping it out and selling the parts on eBay (they go for a pretty penny since they are not made any more, especially the controller), but I think it would be fun to play with it a bit before doing so. It is a "GS3055-I" controller, if that tells you anything. I did google it and found some information, but I thought maybe someone here might know more.
