Lately I've been getting false alarms at night when armed in stay mode. What's really weird is there is no message "hit * to see faults" after I disarm the system AND there is nothing at all logged in the alarmdecoder event log. This is happening more and more often, what is going on?
Could old batteries in wireless sensors cause this? I would think they would show up as a zone fault?
Alarmdecoder is up to date and has been in use for well over a year now trouble free.
