Sonix Io Unit Technical Manual
SONIX IO TECHNICAL MANUAL
TM366 / A June 2022 www.eaton.com
5 Available features
5.1 Alarm activation and Acknowledge
The Sonix Io unit has 6 pairs of alarm activation input
and alarm acknowledge output. Each pair is configured
to be associated with an alarm(s) set/trigger on the PA/
GA system.
ote:
N
Most of the input and outputs on the Sonix Io are configured in
software, please see the SAS manual for more details.
5.1.1 Activation
The alarm initiation inputs 1 – 6 are independent of each
other and can be configured to activate one or more
alarms out of the twelve alarms available. Alarms 6 to 12
are not usually used but can be utilised as part a system
customisation.
Multiple inputs can be configured to activate the same
alarm, this allows for isolated connections to multiple
independent systems. This feature can also be used to
generate additional independent acknowledge outputs
where there is un-used capacity on the unit.
ote:
N
Alarm initiate inputs can be associated with multiple PA/GA
Alarms and will activate all associated outputs when initiated.
5.1.2 Acknowledge
The acknowledge output will activate on any associated
PA/GA system alarms being active. For example, if the
input was configured to be associated with alarms 1, 2
and 3, then the acknowledge output will activate when
either alarms 1, 2 or 3 activate.
ote:
N
It is not required to utilise the Alarm activation input in order to
generate an alarm acknowledge output, but they are configured as a
pair and not independently.
5.1.3 Zoning and Zoned alarms
Currently Zoning for the Alarms is fixed inside the Sonix
2Mx central controller firmware. By default it is set to
all zones. Customisation is available on request, please
contact your local Eaton representative.
ote:
N
Specific zoning requires custom 2Mx firmware, available on
request.
ote:
N
Zoned Alarms are possible on the Sonix PA/GA system but are
considered as ETO.
5.1.4 Alarm Inhibit
The alarm inhibit input is used to prevent alarm
activation of the Sonix Io Alarm inputs. While the inhibit
is active the alarm inputs are ignored, its intended use
is to allow for the maintenance of third-party systems or
cabling without needing to modify the PA/GA system.
ote:
N
Eaton recommends that this input be used with a key switch to
prevent accidental activation.
Warning:
Activating the Alarm Inhibit will
prevent ALL alarms from being remotely
activated via the Sonix Io unit but manual
initiation via access panels is still possible.
5.2 Audio input
The Sonix Io has 2 audio inputs: Pbx and Aux (-iliary).
They are comprised of a transformer isolated line-
level audio input and associated key-line for activation.
Activating the key-line will cause the Io unit to request
access to the PA/GA system to broadcast the available
audio on Io unit input. Once the PA/GA system has
given access to the Io unit, it will begin passing audio
through.

5.2.1 Priority
The priority of these audio inputs into the PA/GA system
is defined by the priority configuration option set on the
Sonix Io unit. If both inputs are active, then the Pbx input
will be given higher priority over the Aux input.
ote:
N
The Pbx input has a higher priority than the Aux input and will
override the Aux input.
5.2.2 Zoning
Currently zoning for the two inputs is fixed inside the
Sonix 2Mx central controller firmware. Customisation
is available on request, please contact your local Eaton
representative.
ote:
N
Zoning requires custom 2Mx firmware, available on request.
5.2.3 Routine chime
The Sonix Io can be configured to play one of three
different chimes before each routine speech broadcast,
the chimes are referred to as single, double and triple
bong. Selection of a chime creates a delay before
routing the incoming audio to the PA/GA system whilst
the chime plays.
