Customer Alarm Outputs
There are two customer alarm outputs (normally closed): bus
voltage and power system status alarm. The bus voltage alarm
activates (opens) if any bus voltage goes low or is lost. The
power system status alarm activates (opens) for any bad sta-
tus. These outputs are optically isolated and can drive relays
or annunciator panels.
