HLIE Interface Operation
The EV3000 Emergency Warning and Intercommunications System (EWIS) main central processing
unit communicates via a RS485 bus with a High Level Interface Expander in an FACP or Serial
Parallel Board.
A fault in the EV3000 will be indicated by the Master Control Panel which in turn initiates, via the
Common Fault Relay Board and Brigade PSU Monitor Board, a Warning System Fault indication on
the FACP.
