Stock alarm question

I am new here but trust me you guys will see more of me. I just got a '92 SVX and i have cleaned it up (you guys should have seen how durty this car was inside) and put my subs in and today the CD reciver will be going in. My only problem that i havent worked out is the alarm. In the manual it says that you can arm the alarm by pushing the button in the car. but to this day (with the ignition on, off..) when i push the button the little light still wont blink.
My other car the one ill have to sell for bearing.... is a 87 Nissan pulsar and i installed the alarm myself so i am in confusion with this high tech 92 stuff
