I have a new Pro 2000 system with only window/door sensors installed. It all set up ok, but when I have the system in Run2 ( pleasant chime) mode, and have some windows or doors open the console randomly chimes, always 4 chimes and sometimes 3-4 minutes apart and sometimes 35-40 minutes apart. Any ideas why?/ All are installed with new batteries and the console does not show any flashing lights indicating any problems. The only flashing light is the monitoring light, which I assume once the Monitoring company gets me set up should clear.
Thanks!
