43.6 Alarms
The UPS is equipped with intelligent internal diagnostics that provide power supply
alarm information. Open collector opto-coupled transistors isolate the alarm signals,
which are present on the 7-pin power and alarm connector. The service provider can
monitor these alarm signals to isolate problems and take corrective action.
Table 43-3 describes the UPS alarms, as well as provides the output signal levels at
the power and alarm connector pins.
