12.4 Priority Manager Configuration
Each zone microphone, fireman microphone or audio input available in the system must have its priority defined in order to ensure
correct operation, as intended for sound emergency systems.

Message priority mode in case of conflict – FIFO / LIFO
Priority Resolve Mode – this is a global system function which defines the system’s behaviour in case a conflict occurs.
The conflict being a simultaneous transmission to the speaker zone from two or more audio sources of the same priority.
For FIFO (First in first out) – in the case when Source 1 of Priority X is transmitting to Output Y and after some time Source 2
of Priority X wants to transmit to Output Y too, Source 2 can not transmit until Source 1 has finished transmitting to Output Y.
For LIFO (Last in first out) – in the case when Source 1 of Priority X is transmitting on Output Y (speaker zone) and, after some
time, Source 2 of Priority X will start transmitting on Output Y (speaker zone) too, then Source 2 will replace Source 1, as
transmitting, and will commence transmitting to Output Y.
Priority Resolve Mode also determines the method of dynamic assignment of a backup power amplifier in case a failure
occurs of the amplifier modules which are responsible for transmission of simultaneous messages of the same priorities.
In case two equally prioritized messages are executed to various zones, Message 1 of Priority (100), Message 2 of Priority (100)
too, which was matriced after Message 1 – when an amplifier module failure occurs for the
FIFO mode: the amplifier which
supplies Message 1 will not be taken over by Message 2 until Message 1 (matrix) has been completed; for LIFO – the Message
1 amplifier module will be disconnected and assigned as a backup amplifier for Message 2.
