Microphone precedence and warning signal
When the precedence contacts (PR and +12V) on the rear terminal
block are closed, all the inputs except for MIC.1 and TEL./EMERG are
muted (it is in any case possible to use the micro-switches to program-
me the inputs to be muted and priority of the precedence contact).
Closing the contact generates a
two-tone warning signal (CHIME).
