I heard about this years ago when I had my Amigo. It had been broken into in front of my girlfriend's house, and they attempted to steal it. They destroyed the steering column tryng to tap the ignition, and since they couldnt get it, they just decided to steal or destroy anything they could get their hands on. Out of vandalism, my Amigo was almost a total to the insurance. The thing is, my alarm never went off and my alarm pager never sounded. After all was said and done, I was told by the insurance company that the alarm fuse was shorted out by some sort of electronic jolt/charge sent to it. He said there were many ways of doing it (wouldnt get into it) as long as the thief knew what they were doing.
Anyways, I was able to replace my alarm (since that also was one of the things stolen, of all things!) with a Viper system that came with a backup power module that ran on somethng similar to a power cell for a stereo, and ALSO had a non parallel fuse that automatically ran from the backup cell. If a power loss was was detected, the power cell would take over, and anytime the power cell took over, the alarm would sound regardless, even just to let you know that there was a change in power usage. A yes, it came with an alarm pager, and man, those can be so very useful. Exceot when you are at a mall and every Tom, Dick, and Harry bumps your car.
