As some of you know, I have a 2002 Ademco Vista20p that came preinstalled in my house. This morning in the wee hours of the morning I woke up to an Alarm Condition on Zone 2 (Living Room Motion) AND Zone 10 (Master Bedroom Window). If anyone has used Zone Doubling on a Vista before, you would know Zone 2 and 10 are on the same terminals.
My concern is that it was armed STAY, via scheduling, which sometimes the system has trouble with and crashes. Since it was Armed Stay, why did Zone 2 Activate (if its an interior follower). I think its a hardware issue, and I have preliminary plans to replace it with a Vista128FBP so it can cover my home Fire Alarm System as well.
Let me know what your thoughts are!
