FC-MIM Microphone Interface Module
Connector P7 provides a connection for the optional FC-MIM Microphone Interface Module
which is used to connect the FC-RM Remote Microphone Module to provide remote
microphone paging capabilities (refer to the Remote Microphone Installation Document
ACC-ZPM Zone Page Module
Connector P3 provides a connection for the ACC-ZPM Zone Page Module which is used to
