External Power Fault
Alarm triggers when the supplied DC power is > 33 VDC. When this occurs,
the device automatically switches to operation using the internal battery. If
the supplied voltage drops to < 30 VDC, the device automatically returns to
operation using external power. If the external power source is known to be
good, then the AC/DC Power Supply may be faulty and need replacement.
