is there a fuse that might of blew?? it all of a sudden happened becasue i was constantly disconnecting the battery over a few weeks due to mods and it would make its noise. one day it wouldnt make any noise.. help!!

 

Mighta' just blew your siren... happened to me. I don't know what alarm system you have, I have "CODE ALARM". Might just crapped itself on the second chirp when I was arming it. The way I checked it was that I used my meter on the wires of the siren and armed/disarmed the alarm a couple of times and verified that I was getting voltage to the siren unit itself. I had voltage spikes on mine, so I knew the siren crapped out. Got a free replacement (one for one swap, lifetime warranty) and been good to go ever since...

But I guess that depends on what brand you have
