USER ALARM OUTPUTS
There are two user alarm outputs (normally closed): bus volt-
age 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 that require no more than 120 milliamps.
