5.2.2.3 BMB01 and Monitored Fault Input Connection for Third-Party Equipment Fault Monitoring
The BMB01 analogue inputs can be used for fault inputs from other equipment where the fault wiring is
monitored by the iPAM400.
Only the analogue inputs of the BMB01 can support resistively monitored fault inputs.
This is the preferred fault monitoring method, because any cable faults will be reported.
