4.14. Priority input (PRIORITY IN)
Unbalanced analog input with an RJ45 connector and a sensitivity of 0 dBu (775 mV).
It has a priority contact which is activated by connecting pin no. 6 to pin no. 8 of the connector. When
this contact is activated, any signal of a lower priority level is cut off and priority is given to the PRIORITY
IN input, while the paging security auxiliary relay is activated at the same time.
This input is particularly suitable for receiving local announcements (e.g. a microphone with a speech
preference button…).
Cat 5 STP cable must be used for its connection.
