Actually yeah, even the basic alarm system we have at my home has a battery backup. I have a hard time swallowing that just cutting the power to the building would put any alarm system out of commission... I'm pretty sure the people that design them thought about the whole no power thing It's just really odd to be honest, tons and tons of $ worth of equipment in that building and they have an alarm that can be defeated by just cutting the power? Not trying to insinuate anything, just curious things to think about.
