The alarm itself seems to work fine, but I was wondering about the indicator light. Weather the system is armed or not, all it does is blink. It never changes. You would think it would stop when you disarm the system, but it don't, what's up with that? Also, I would like to program it to passive arm, but I don't have a bitwriter, how can I do that with out one. I've heard that there is supposed ot be a way.
