Operation of MNS-LOC
The LOC-Rs provide switch control and indicator LEDs for 8 messages that are played by the MNS-100EXP.  Throwing a message selection switch on any LOC-R signals the MNS-100EXP, which in turn sends a confirmation command back to all LOC-Rs to light the associated message LED, and plays the requested message.
