15.0 Autonomous Control Unit and Local
Operating Consoles
The Autonomous Control Unit (ACU) and the MMX Local Operating Consoles (MMX-LOCs)
connect to the MMX Mass Notification System (MNS) remotely. The MNS uses the ACU and
the MMX-LOCs to broadcast live announcements and pre-recorded digital messages to
multiple locations in a building.
15.1 ACU and MMX-LOC Configuration
The ACU has a paging microphone that connects directly to the main board through a ribbon
cable connection. The microphone has priority over the MMX-LOC paging microphones and
all digital messages. The ACU contains an IPS switch adder module that broadcasts pre-
recorded digital messages. Each button on the switch adder module can be configured as a
zone switch in the Configurator. For each zone switch, a priority level can be assigned and a
digital message can be attached.
The MMX-LOC contains a switching and input module combination that broadcasts pre-
recorded digital messages.
Both the ACU and the MMX-LOC contain a paging module that broadcasts announcements
and a display that monitors MNS events.
15.2 Setting priorities for zones and switches
You set the priority of zones and switches in the Configurator.
To set priority for a zone or a switch
1. In the Configurator, double-click in the Priority column for the zone or switch.
2. Click a priority in the pulldown menu.
This number is the priority given to digital messages that are correlated with this zone or
switch. The priority ranges from -95% (lowest) through Normal (default) to +95%
(highest).
15.3 Broadcast Priority
Announcements or digital messages from an ACU override broadcasts already in progress
from an MMX-LOC. The broadcast of announcements or digital messages from an MMX-LOC
occurs on a first come first serve basis. If one MMX-LOC is broadcasting, another MMX-LOC
cannot broadcast until the first MMX-LOC has stopped broadcasting. The following list
identifies broadcast priorities from highest (1) to lowest (6).
1. ACU announcement by paging microphone
2. ACU highest priority digital messages (priority is set in the Configurator)
3. ACU lowest priority digital messages (priority is set in the Configurator)
4. MMX-LOC announcement by paging microphone
5. MMX-LOC highest priority digital messages (priority is set in the Configurator)
6. MMX-LOC lowest priority digital messages (priority is set in the Configurator)
