6 .7 .1 Message slot priority
The unit has configurable priority structure to the
messages. Message recorded into slot 1 has a higher
priority than message 2, with message 12 the lowest
priority.
This allows the user to escalate warnings or information
broadcasts depending the site conditions.
ote:
N
Initiation of a higher priority message while playback is active will
cause unit to abort current playback and begin playback of higher prior-
ity message.
6 .7 .2 Connected via CAT6A cables
A Sonix Ms12 connected into the Sonix PA/GA system
via the CAT6A cables has more configuration and
interaction with the PA/GA system.
6 .7 .2 .1 Message Holding
While the system is busy and the Ms12 unit is un-able
to broadcast, the playback request will be ‘held’ for
approximately 30 seconds before abandoning playback.
6 .7 .2 .2 Message Zoning
Zoning for the message playback is common for all
message slots. The configuration includes a map for all
available zones to be individually selected.
See SAS manual for more details.
6 .7 .2 .3 Ms12 Unit priority
All audio sources in a Sonix PA/GA system have a
configurable priority of broadcast. This allows the
system to correctly choose which audio to broadcast in
the event of multiple events occurring simultaneously.

Priority should be configured as part of the holistic PA/GA system
configuration as per the cause and effect.
See SAS manual for more details.
6 .7 .2 .4 Emergency speech auto-elevate
Normal message playback is broadcast as routine
speech, but each message slot can be individually
configured to auto-elevate to Emergency Speech.
If a message is elevated to Emergency Speech
broadcast, its priority is raised above any active Alarms
on the PA/GA system and the chime is changed to an
important message chime; single short burst of 1 kHz.
See SAS manual for more details.
6 .7 .2 .5 Remote playback abort
Activation of Alarm Cancel on the PA/GA system will
cause the unit to clear its active message playback and
queued message. This feature cannot be disabled.
ote:
N
Cancelling of an active alarm has the side effect of clearing any
message queue.
6 .7 .3 Connected via isolated audio and key lines
Using the Ms12 connected via a two pair cable to
connect audio and control lines to a Sonix Io instead of
using the RJ45 connectors and CAT6A cabling. When
the unit enters playback the control lines become active
and the recorded message is relayed over the audio pair.
Any connections using the isolated audio and key lines
have no system information available to understand
when to queue a message. Therefore, recorded
messages will automatically enter playback. Speech
broadcast priority of the Ms12 message is now set by
the priority of the Sonix Io unit. The message will only
be broadcast if the priority of the Sonix Io unit is higher
than the currently active system priority.
The key line polarity can be configured to be normally
open or normally closed, but the output is OPEN when
the unit is in an un-powered state.
Warning:
Using normally closed, open when
active, setting for the key line can cause the
PA/GA system to broadcast a non-message
permanently if the key line cable is dislodged.
This NOT the recommended setting.
ote:
N
This connection relies on the Sonix Io unit to be configured cor-
rectly for both priority and the appropriate inputs to be enabled.

PA/GA Zoning and broadcast priority are set by other units in the
system in this connection schema.
