Console Problem

[fairmont]

I have recently encountered a new situation.  The alarm works fine, but when I switch to "install" the first three lights are on.  I can't figure out why this has suddenly happened.  Any help is greatly appreciated.

... when I switch to "install" the first three lights are on. 

I think [this off the top of my head] while in install mode.. those are zone lights.. indicating you have DS10A's, or MS10A's installed.

And it's a good idea to label each "DS" or "MS" as Zone 1,2, and 3.
