My alarm sounded twice for about 3-4 seconds in the same day, and once the day before. The yellow trouble light came on and indicated Zone 3 in red. This would be fuse/Aux trouble, however my neighbor recently replaced his battery on his system which was put in the same time as mine (same system).

How should I check the fuse to see if that is the problem? Also can I use a 12V 5AH to replace the 12V 4AH that was in the box? My neighbor pulled as 12V 5AH from his and I'm not sure why ours are different.

Thanks!

Is the zone 3 display _after_ pressing *2 to activate trouble display? If so, then you can check the fuse by simply popping it out of the holder on the top of the motherboard and checking it with a meter. You _could_ have a bad siren, but siren circuit failure is one of the ways that this particular model is known to fail.

Remember, this thing is 8-10+ years old, the laws of thermodynamics hasn't been repealed.
