My siren seemed normal, until ealier, I noticed that it was very quiet. I triggered the alarm, and it is so quiet that no one would notice it was going off. Any ideas? Thanks. Oh yeah, Compustar cm3000 with 2wfmr remote.

 

did you look at their website?, http://www.compustar.org they have a owners manual on there, it could help...

I have the alarm close to 3 years and haven't heard of that problem, sorry can't help.

 

The manual doesnt do anything for me. Thanks though. Siren I think only has a few wires though. So I dont think it is hard to mess it up. It was working when I first had it installed, and now it is quiet. wtf???

 

Are you sure you did not hit the "mute" on the remote?

I have done that once or twice... press button 1&2 at the same time and then let go.

 

Yes, I have checked the mute.

 

maybe a stupid suggestion but..........maybe your battery is out of juice.

 

check the ground for the siren
make sure its (the horn) pointing down so no water gets in
check alarm ground
