The easy way to do that is with a positive signal system. That is, the
little transmitter chirps once every couple of seconds when things are
"good". When it stops chirping (batteries low, shot, crunched, or alarm
triggered) you light the alarm fuse.

If you aren't going into business - somebody should. I think it is a
neat idea although it would need a way to detect that the electronic
box is being crunched or shot at etc etc.
