In order to function correctly care must be taken when
confi guring the Sonix systems to ensure that both
sides have identical priorities, Alarm tones and zoning.
Please discuss your requirements with your local Eaton
representative.
AB+ allows systems to be designed with an imbalance
in the input sources, Figure 12 shows a system with
the Ms12 message store connected to the B side
only. When any source is active, its audio and control
information is shared between the 2Mx controllers
and so can be routed to available to both systems
simultaneously.
7.2.1 AB+
The Sonix feature, AB+, is an evolution for A&B
systems. Its primary purpose to provide 100% coverage
even when systems are in fault/out of balance. The
feature makes extensive use of the Sync Bus to allow
both systems to ‘see’ the active alarms and broadcasts
on the other system. This allows the 2Mx controller in
each system to make an informed decision about what
should be active on its system and can choose the
broadcast, and synchronised with, the other systems
active audio.
The specific advantages of this are that any imbalance
in the inputs, either by design or due a fault, is
automatically duplicated and full coverage maintained.
