Re: Radionics D7212B1 Panel Help

Badenov,

Thanks for the detailed information on the Datalock code. It will be useful
as I investigate the panel. I like these puzzels and I might end up with a
good alarm system when I'm finish, all the better.

If I come to some useful results I'll surely inform you.
