I have a very old (!) DSC 2550 and need some help. I was working on re- connecting the wires to the siren that a squirrel had eaten through, and now all of my zone lights on the keypads are on and the system will not arm. I have reset the system by powering down, but no change. Any ideas?
Thanks,
JD
I don't use DSC but if your panel has fuses you can start by checking them first. RW
I found the problems...one was a fuse and the other was a programming issue...programmed to show "not closed loop" or something like that.
Thanks,
