39.5 Alarms
The UPS is equipped with intelligent internal diagnostics that provide power supply
alarm information. Open collector opto-isolators isolate the alarm signals which are
present on the power and alarm connector. The service provider can monitor these
alarm signals to isolate problems and take corrective action.
Table 39-3 describes the UPS alarm signal and output levels.
