Re: 12vdc panel

["Doug L" <vssdoug@xxxxxxx>]

Section 1.1 of the North American 1555MX installation manual states that the
panel will not run if the AC line frequency drops below 55.5Hz, presumably
so DSC can sell a different version outside of North America. If this
"feature" actually works then it should prevent the panel from running on DC
applied to the AC terminals.
