For example, a priority of -1 assigned to a zone switch on the ACU’s IPS switch adder module
has a higher priority than a priority of +9 assigned to a zone correlated to the input module
used by the FX-LOC. Refer to Figure 69.
Figure 69 ACU and LOC Configuration
The FX-LOC paging microphones are hardwired to the board belonging to the ACU paging
microphone. They have a lower priority than the IPS switch adder module messages used by
the ACU but a higher priority than the FDS switching module messages used by the FX-LOC.
The FX-LOC broadcasts digital messages using an FDS switching module. Each switch on
this switching module is hardwired to inputs on an input module that are correlated to input
zones in the configuration. Each input is correlated to its own input zone with a digital
message attached to each zone. Priority for FX-LOC digital messages is set between the input
zones. For example, an input zone with an assigned priority of 70% will override an input zone
with an assigned priority of 50%. Refer to the figure below.
