The Edwards MCDI Series Text Message Annunciator Driver allows dry contact activation of any Edwards Message Center. It may be used to activate messages loaded in a single message center or a message in multiple message centers. A contact closure instructs the CPU to transmit an activation message to the message center through its RS485 communication output.
