4 Installation and connectivity
4.1 Physical installation
The Sonix Io is a DIN rail mount unit, intended to be
mounted inside the PA/GA cabinet on most standard EN
60715 rails:
• EN 50022 (Top hat, TS35, TS35D, type “O” or type
“Ω”) 35 x 7.5/15 mm rail,
• EN 50045 (mini Top hat or TS15) 15 x 5.5 mm rail,
• EN 50035 (type G or TS32) 32 x 15 mm.
Unit is simply clipped onto the appropriate rail, always
check that all sets of fixings have engaged correctly on
the rail.
ote:N Care must be taken to ensure that the product is correctly sup-
ported within the cabinet. Always check that both sets of fixings have
fully engaged on the rail and the unit is secured on both ends, with no
possibility of it to slide along the din rail.
4.2 DC Power
The Sonix Io is powered externally by 48 V dc. Eaton
recommends the supply voltage to be taken from
dedicated dc power output connection of the Sonix
Pm10 (see Pm10 Product Manual for connection details).
Green LED (D1) visible next to the power supply input
terminals illuminates to indicate that unit is powered up.
Figure 2 - DC Power connections
ote:N As these cables are power feeds, they should be – where pos-
sible – routed within the PA/GA system in a separate way to avoid
contact with signal or audio cables and reduce the possibility of inter-
ference.
Warning: Observe the polarity of incoming
power supply cables.
• Solid: 4.0 mm2
• Stranded: 2.5 mm2including sleeved or
non-sleeved ferrule
4.3 Earth connection
The Sonix Io unit has an M4 stud for connection to
Earth. The Earth connection is used as a functional
reference for the unit screening only.
It is strongly recommended that any connection be
made to Telecoms Earth only.
Cable sizing is as follows:
Recommended 4.0 mm2
Minimum 2.5 mm2
4.4 Io Bus connections
The Sonix Io connects to the Sonix PA/GA system via
the Io bus communication channel utilising duplicated
CAT6A cables. This connection carries bi-directional
audio and serial data using RS-485 standard. The Sonix
PA/GA convention is that the Io bus uses BLUE coloured
CAT6A cables which connect to the colour coordinated
Io Bus sockets on the rear of the 2Mx unit.

Table 2 - IO Bus description
How the unit is connected in the system depends on the
number of units on the Io Bus.
The 2Mx Io bus connections are always top-top and
bottom-bottom, i.e. top port of the Sonix Io connects to
the top port of the Io Bus on the 2Mx. Whereas any inter
unit Io bus connections are always top-bottom.
For single unit the return link (bottom port of Io)
connects to the bottom port of the Io Bus on the 2Mx,
as shown below.

cables do not exceed 25 meters in length, regardless of the system
configuration.
4.5 Input connections
The Sonix Io unit has several inputs that can be
configured to be volt-free or driven. Each input is
independent and can be configured as required. See
section 5 and SAS manual for more details on available
configuration options.
4.5.1 Volt-free or 5-12V driven
To select between Volt-free and Driven input
configurations requires a change of jumper links
on the PCB. This change is defined on each input
independently.

Sonix Io Unit Technical Manual
SONIX IO TECHNICAL MANUAL TM366 / A June 2022 www.eaton.com
ote:N Inputs are not voltage polarity conscious when in driven mode
and can be wired either way around.
ote:N Volt-free mode supplies a low current from a local 5V supply to
sense the contact position. This is common to all inputs and care must
be taken to avoid swapping the common on non-isolated systems.
Warning: Do not exceed 30 V ac or 60 V dc input
potential, risk of shock.
The maximum input voltage when Driven mode is
selected is 12 V dc or ac. This is due to the current
limiting resistor in each input circuit reaching its
maximum power threshold. If higher voltages are a
system requirement then a relay should be used to
isolate the inputs from the source.
Warning: Do not exceed 12 V dc/ac input drive
or damage might occur to unit.
4.5.2 Connecting to sources greater than 12 V
A relay should be used to isolate the input from any
sources that are greater than 12 V.
Figure 6 - Isolated input for > 12 V source
ote:N The Sonix Io input should be configured as volt-free when using
an external isolating relay.
4.5.3 Polarity
Polarity of the inputs are congured by SAS and can be
either normally open or normally closed. The unit will
ignore its inputs until after the conguration has been
loaded on a cold start to avoid incorrect latch up. This
takes approximately 7 seconds.
4.6 Output connections
The Sonix Io output ports are volt-free relay contacts
with hardware selectable normally open or normally
closed. The relays controlling the outputs are small low
power variants and are only rated for 1A at 24 V dc.
Warning: Do not exceed 30 V ac or 24 V dc on
the relay contacts.
4.6.1 Extended voltage or duplicate output support
For controlling voltages in excess of 24 V dc / 30 V
ac a correctly rated external relay should be used to
provide the isolation. Also, if multiple independent
outputs are required by the system design, then
isolation should be maintained by using an external
relay with multiple contacts.
Figure 7 - Duplicating outputs
4.6.2 Polarity
The polarity of the outputs is set by a 2-position
jumper link for each output. These can be found
adjacent to each output on the PCB.

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.
Figure 9 - Pbx input connections
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.

All chime options for routine speech broadcasts can be
set in conguration, see SAS Product Manual for details.
5.2.4 Broadcasting as Emergency speech
To broadcast any incoming audio as Emergency Speech
the Important message input needs to be activated rst.
If the Important message input is active, then the Sonix
Io will ag the broadcast as Emergency speech and it
will be given higher priority on the PA/GA system.
5.2.4.1 Important Message input
The important message input is a latching input with
timeout after 30 seconds of no active key-line input.
Alarm cancel also resets the input ag.
ote:N The Important Message input is a latching input, a brief activation
will cause it to hold active until the timeout occurs or PA/GA system
alarm cancel in activated.
5.2.5 Emergency speech chime
The Sonix Io can be congured to play one of three
different chimes before each emergency speech
broadcast. These chimes are different to the routine
speech chimes. Selection of a chime creates a delay
between activating PTT and routing voice to the PA/GA
system while the chime plays.
Warning: As with routine, emergency chime will
override the rst few seconds of the incoming
audio stream and with no method to buffer it,
causing the audio to be lost.
Available chimes on the Io are:

can be set in conguration, see SAS Product Manual for
details.
5.2.6 Background Music
The Aux input is used to deliver background music
(BGM) to the PA/GA system. This is controlled and
setup elsewhere (see 2Mx Technical Manual), but the
Aux key-line needs to be active before BGM can be
activated on the system.
ote:N Eaton suggest using a rack mounted switch to globally enable/
disable BGM.
5.2.7 Audio monitoring and timeout
Each audio input can be monitored for DTMF tones
during idle, while the key-line is not active. Also,
excessive key-line durations can be monitored as a fault
situation if congured in software.
See SAS manual for more details.
5.3 Audio Output
The Sonix Io has a single audio output, with transformer
isolated line-level audio and associated key-line.
The key-line will activate and audio will be routed out on
the following events as standard:
• 10 seconds of any alarm tone every ~ 64 seconds
• All Emergency Speech
• All Routine Speech
ote:N Customisations of the events that enable this output are avail-
able as ETO.

5.4 Other PA/GA system status outputs
The Sonix Io unit has following general outputs, driven
from the Sonix PA/GA system.
5.4.1 Fault outputs
The Sonix Io unit has 2 fault outputs, Global Fault and
Program Fault, also known as Major and Minor faults
respectively. The source of the faults is chosen by the
2Mx central controller, with the Global fault activating
on any issues with the system and the Program fault
normally restricted to a subset. These faults can be
disabled in software, see SAS manual for details.
ote:N Customisation of the fault outputs currently requires ETO firm-
ware, please contact your local Eaton representative to discuss your
requirements.
5.4.2 Entertainment and Auxiliary Mute
The Entertainment and Auxiliary mutes activate on any
broadcast that is above Routine Speech, i.e. Alarms
and Emergency Speech. It is intended to silence any
entertainment systems, such as background music,
televisions or private cinema, and allow any broadcast
messages to be clearly received.
Polarity is congured using external links, see section
4.6.2.
ote:N Entertainment Mute does not activate on routine speech.
ote:N Auxiliary mute follows the same pattern as Entertainment mute
and does not activate on routine speech.
5.4.3 System Busy
The System Busy output is activated whenever the
system is no longer idle, i.e. during Routine speech,
Alarms and Emergency speech. This includes
background music. Any testing activity like sense tests
and Ticktone (See 350-d amplier manual for more
details) are not included.
5.4.4 Ships Whistle
The Ships Whistle output is intended to be connected
to third-party equipment, typically the collision alert
warning or international maritime destress on vessels,
to allow that system to be activated when an alarm
is running. The alarm, or multiple alarms, it will be
associated with, are set as part of Sonix Io conguration.
The output can also be congured to pulse in sync with
the alarm cadence.
ote:N Cadence options only impact output when selected with inter-
rupted alarms.
Please see SAS manual for more complete conguration
details.
5.5 Other PA/GA system control inputs
The Sonix Io unit has the following control inputs into
Sonix PA/GA system.
5.5.1 Alarm Cancel
The Alarm Cancel input generates a short, approximately
2 seconds, active pulse when the input is rst activated
and will only re-trigger if the input is subsequently
cleared. This is to prevent a fault on the input from
locking the system out of generating alarms.
ote:N Holding this input active does NOT prevent alarms being acti-
vated on the Sonix Io or elsewhere after the initial request.
5.5.2 Alarm Attenuate
The Alarm Attenuate input is also an edge triggered
signal. Each new activation will cause the system to
change state between full volume alarms and attenuated
alarms. Attenuated alarms can be disabled elsewhere
in the system and the input will only have an effect if an
alarm is currently active.
ote:N Activating this input with no alarm will generate a short indicator
event on any Sonix Hmi-26 access panel connected to the system.
5.6 Fault monitoring and reporting
The Sonix Io unit has built-in fault monitoring for the
following issues:
• Temperature
• Internal audio pathways using idle DTMF monitoring
• External audio input using idle DTMF monitoring
• External audio timeout monitoring
• PA/GA system Data monitoring
• PA/GA audio pathways using idle DTMF monitoring
All faults are reported into the Sonix PA/GA system via
the 2Mx central controller and the Sonix Administration
Software (SAS).

6 Conguration
The conguration options are detailed within the SAS
manual.
6.1 Ping-set
To ping-set a Sonix Io the following procedure needs to
be followed:
1. Connect Computer with SAS installed and working
with the system via the data connection cable.
2. Navigate to Io configuration screen.
3. Press Ping-set and enter a new Unit ID.
ote:N Unit ID’s need to be unique for all Io units on the system.
4. Once the software has sent the ping-set command
ALL Io units that receive the command will be
waiting to accept for 10 seconds.
5. Activating Alarm Cancel on the Io unit during this 10
second window will cause that local panel to accept
the new Unit ID.
6. Any Io unit which has not had Alarm Cancel pressed
during the 10 second window will discard the
command and retain their current Unit ID and
configuration.
6.2 Programming the unit
Programming the unit is usually performed during
manufacture and is not usually required in the eld.
1. Ensure 48V dc power input is available
2. Back-up configuration if required
ote:N Configuration can be corrupted during programming, re-configu-
ration after programming is recommended
3. Disconnect unit from PA/GA system
4. Isolate unit from third-party connections
5. Connect programmer to J10, carefully observe the
orientation key
6. Program unit using Eaton approved firmware
7. Verify firmware on unit
8. Power cycle unit
9. Reconnect PA/GA system and verify/update
configuration as required
10. Reconnect third-party connections
Warning: Only programme with Eaton approved
rmware.
Warning: Unit will likely activate its outputs in
random patterns during programming.
7 Customisation
The standard version of the Sonix Io unit has been
designed with mostly xed function inputs and outputs
and some limited conguration., any customisations
should be discussed with your local Eaton representative
before ordering.
7.1 Firmware customisation
Please contact your Eaton representative if the standard
operation of the Sonix system and/or Io unit is not
fullling the needs of your system.
8 Maintenance
The Io unit itself does not require any specic
maintenance but the following general maintenance
should be performed monthly:
Warning: Remove fuse / power off the unit
before proceeding!
• Check the unit for visible damage (scratches, bumps).
• Check connections and cable integrity - replace
damaged cables, tighten terminal connector’s loose
screws.
• Check unit fixing to rack
•
Notice: Do not use sharp objects, water, aggressive
cleaning agents or solvent to clean the unit.
