Double-Secure Power Input Fault Alarm
The power inputs are designed as a "common negative", which implies that
the negative input is connected, but "double-secure" is supported to
prevent the un-notified failure of power from one of the negative inputs. If
one of the negative power input fails, the system will detect it and the
system will trigger the event if the users set the fault alarm or event log for
powers.
