4.3.3 Un-used connectors
The unit has connectors which are not certified for
intrinsically safe installations and must not be used
in the hazardous area. It is recommended the unit be
removed from the hazardous area if reprogramming the
functionality of the unit is required. The connectors are
listed below:
Connector Function For use by Eaton Personnel only
J2, J6 Local power Yes
J16, J17 Audio and data expansion Yes
J4, J8 Programming Yes
Table 2 - List of un-used connectors
5 Unit operation
5.1 Data communications
The Hmi-5 unit communicates with the Sonix PA/GA
system rack via an Hmi Tu using a low power serial
and a balanced audio pathway. The protocol used is
a proprietary Sonix datagram format with messages
exchanged every 100ms. The datagrams contain system
status and activity from the PA/GA and access panel
status and activity going to the PA/GA rack. While
idle the Hmi-5 access panel is transmitting low level
audio that is monitored by the PA/GA rack to detect
degradation in the audio pathway.
The Hmi-5 implements different electrical interface
to the Sonix Hmi-26 access panel and this requires a
hardware link change on the Hmi Tu (see Hmi Tu manual
for details).
5.2 A & B duplication
The Sonix Hmi-5 access panel is a duplicated unit with
an A and B side. There is a small common section,
namely Microphone, Buttons and indicators. The two
sides signal each other basic status, this facilitates
passing control of the LED indicators to the side in
the best state. By default A side will control the LED
indicators.
Warning: Both sides of an Hmi-5 need to have
identical functionality and conguration to ensure
correct operation.
ote:N It is not required to use both sides, if non-duplicated operation is
required A side should be used in preference.
5.3 Microphone options
The standard Hmi-5 unit is designed and customised
for each order, which is then tailored to the user’s
requirements. Please discuss specific requirements with
your local Eaton representative before ordering.
5.3.1 Hand-held microphone
The standard microphone is a hand-held variant on
a coiled cord, complete with hanger to place the
microphone when not in use. The microphone has an
integral PTT button on the side.
In this configuration it is possible to have up to 5 push
buttons with built-in LED indicators on the unit itself.

Sonix Hmi-5 Technical Manual
12 SONIX HMI-5 TECHNICAL MANUAL TM373 / A June 2022 www.eaton.com
5.3.2 Flush mount microphone
The flush mount variant takes up the space of a normal
button, reducing the maximum button count to 4,
additionally the one of the buttons will have to be
reserved to function as a PTT input.
5.3.3 No microphone
It is also possible to order the Hmi-5 without any
microphone at all, this configuration again has a
maximum of 5 buttons with built-in LED indicators
available.
5.4 Button and LED indicator operation
Each button on the Sonix Hmi-5 can be utilised to
perform a pre-set function. The available functions are
discussed later in this section.
Each button can also be disabled in configuration,
which prevents the button press but does not affect the
indicator operation. This can allow for future expansion
and protected functionality in insecure/remote locations.
Activity indication styles available on buttons:
Off Typically used to indicate associated function is
not active
Slow flashing (~ 0.5 Hz)
Typically used to indicate associated function is
active on the system but not from local access
panel-
Fast flashing (~ 5 Hz) Typically used to indicate associated function is
pre-selected on the access panel
Solid Typically used to indicate associated function is
active on local access panel and system
Breathing (see 6.4.1) Typically used to indicate the access panel is idle
ote:N The breathing indication will stop across all indicators on any but-
ton or indicator activity.
Each indicator can be one of the following colours:
• Red
• Blue
• Yellow
• Green
• Clear
• Orange
• Black (Non-illuminating)
ote:N The standard Hmi-5 push buttons are fitted with long life LED
indicators that have a long MTBF and should not require replacement.
Warning: The IP rating of the Hmi-5 unit
depends on correct construction of the button
and LED indicator, opening the button to change
the LED can adversely affect the rating. Please
contact your local Eaton representative for
guidance on this matter.
The buttons have optional, fitted by default, clear flaps
to prevent accidental operation. These must be specified
during ordering due to the need to maintain IP66 rating
and prevents post-delivery installation.
The flap has a simple operation and will stay open
unless closed.
Figure 5 - Button ap guard operation
Warning: The standard Hmi-5 pushbuttons
normally closed, open when activated, this
means that a broken or loose connection can
cause un-intended activations.
5.4.1 System Idle
During system idle the LED indicators are normally
set up to slowly ‘breathe’. This involves a constantly
varying brightness on the LED at a fairly dim level to give
confidence that the unit is powered, and the indicators
are functional. This has been carefully designed to make
it easy to distinguish between idle and active / off.
5.4.2 Indicator Test (LED Test)
Indicator lamp test button is intended to provide a
simple mechanism for routine maintenance testing of all
indicators on the unit.
On activation all indicators will illuminate solid for at least
1 second and then extinguish and return to indicating the
current state; typically idle.
5.4.3 Push to Talk (with System busy indication)
Push to talk can be assigned to be either a standard
button or the button incorporated on the hand-held
microphone.
If assigned to a standard button the associated indictor
has the following states:
Off PTT is not active
Slow flashing (0.5 Hz) System is busy
Solid PTT is active
ote:N The Hand-held microphone push to talk button is recommended
as it allows for increased functionality on the unit.
ote:N The default PTT action is for Routine Speech broadcast. To broad-
cast emergency speech an Important message button needs to be
available or the required functionality to be defined during ordering.
Warning: The default zoning of PTT must be
specied as part of unit ordering.

5.4.4 Important Message (Emergency Speech)
Important Message is a toggle action button. It will
normally self-clear after ~30 seconds of no action of
either a button press or PTT broadcast. The standard set
up is to require a second action to broadcast Emergency
Speech, i.e. to actively select Important Message then
begin broadcast with PTT.
If assigned to a standard button the associated indictor
has the following states:
Off Important Message is not active
Slow flashing (0.5 Hz) An Important Message is being broadcast on the
system
Solid Important Message is active on the local panel
(may or not be broadcasting)
ote:N An important message broadcast is to all areas unless specified
as part of the unit ordering.
5.4.4.1 Combined Important Message and PTT
A combined PTT and Important Message button will
broadcast Emergency Speech while activated.
The indicator will follow the same pattern as for standard
PT T.
Warning: Check regulatory requirements
regarding Emergency Speech broadcasts as
some require a two-step process to avoid
accidental activation.
5.4.5 Zone button
Zone buttons can be used to give the Hmi-5 access
panel increased speech broadcast exibility by allowing
the pre-selection of broadcast zones before activation of
PT T.
Zone buttons have a timeout of ~6 seconds. If no PTT
or additional zone button activation occurs within this
time window, they all self-clear. Each button activation
resets the timeout counter.
Warning: The default zoning of PTT and zone
buttons must be specied as part of unit
ordering.
If assigned to a standard button the associated indictor
has the following states:
Off Associated Zone(s) are not active
Slow flashing (0.5 Hz) Associated Zone(s) are being broadcast into by
the system
Fast flashing (5 Hz) Associated Zone(s) are pre-selected by the local
panel (PTT not active)
Solid Associated Zone(s) are selected by the local panel
(may or not be broadcasting)
5.4.6 Alarm activation
Alarm activation buttons can be set to activate any one
of Alarms 1 to 6. Alarms by default are all areas, but
xed function zoned alarms are possible (see 6.4.6.1
Zoned alarms).
Typical associated indicator function:
Off Associated Alarm is not active
Slow flashing (0.5 Hz) Associated Alarm is active on the system but not
from the local access panel
Solid Associated Alarm is active from the local access
panel
ote:N Alarm activation function within Sonix PA/GA is NOT a toggle
action, clearing the alarm requires activation of Alarm Cancel.
5.4.6.1 Zoned Alarms
Alarm activation function on the Sonix Hmi-5 are
usually All-Call, i.e. activates the alarm into all areas. It
is possible to change the default action to be a zoned
alarm
ote:N This is not recommended but if zoned alarm activation is required
please discuss with local Eaton representative.
5.4.7 Alarm Cancel
Alarm Cancel button is provided to allow a user to clear
or ‘cancel’ active alarms on the system. Please note
that once pressed there is no method of un-actioning an
Alarm Cancel.
Activating Alarm Cancel button will send a signal to
the 2Mx requesting a clear out of any currently active
alarms. If the activation input is still active, for example a
remote push-button connected into the IO-Tu, then the
alarm will immediately re-activate (although the audio
will pause for up to a second). The alarm cancel signal
self clears after ~ 200 milliseconds to prevent a broken
or stuck button from acting as an un-intended alarm
inhibit.
If assigned to a standard button the associated indictor
has the following states:
Off Alarm Cancel is not active
Fast flashing (5 Hz) Alarm Cancel is active on the system
Solid Alarm Cancel is active locally but not on the
system
ote:N : As part of system design for un-attended access panels in pub-
lic spaces; consideration should be taken as to whether Alarm Cancel is
a protected function.

5.4.8 Alarm Attenuate
Alarm attenuate is a toggle action function, it will only
latch on if an Alarm is active on the PA/GA system.
The alarm attenuate action operates at a system level,
activating this button toggles the current system state
independent of the access panel.
If assigned to a standard button the associated indictor
has the following states:
Off Alarm Attenuate is not active
Fast flashing (5 Hz) Alarm Attenuate is changing state
Solid Alarm Attenuate is active
5.4.9 Alarm Inhibit
Alarm Inhibit is used to prevent automated activation
of alarms from external systems such as Fire & Gas.
It does not prevent manual activation from any access
panel.
If assigned to a standard button the associated indictor
has the following states:
Off Alarm Inhibit is not active
Fast flashing (5 Hz) Alarm Inhibit is active on the system
Solid Alarm Inhibit is active locally
ote:N Not a recommended action for an Hmi-5 access panel. Eaton
recommends that a key switch connected to Sonix Io would be a more
rigorous solution.
5.4.10 Ms12 message initiation
Initiation of a pre-recorded message from the Ms12. The
message can only be initiated if it is loaded (recorded)
and enabled on the Ms12.
If assigned to a standard button the associated indictor

Off Button is not active
Fast flashing (5 Hz) Button is active, message playback requested
ote:N There is no success/failure feedback to the user on the access
panel.
5.4.11 Local Attenuate
Local attenuate is a toggle action function, it can be
used at any point to reduce the output of the local
loudspeaker(s).
Typically, Local Attenuate will be implemented with a
pre-set timeout window to prevent permanent latch up,
values between 5 and 30 minutes.
If assigned to a standard button the associated indictor
has the following states:
Off Local Attenuate is not active
Fast flashing (5 Hz) Local Attenuate is changing state soon
Solid Local Attenuate is active
5.4.12 Background Music control

5.5.2 System Health / System comms health
System health indicator is used to show the system
health and local access panel communications health
status. Due to the single indicator colour, the indicator
can be used to show either a system healthy or a
system fault.
If assigned as a system fault light the indictor has the
following states:
Off System is currently healthy, or access panel is
powered
Fast flashing (5 Hz) Local communications issue
Solid System is not healthy
ote:N Eaton recommends this mode, especially when combined with
idle indicator breathing (see 6.4.1) and suggests a Red button cover/
indicator colour.
If assigned as a system healthy light the indictor has the
following states:
Off System is NOT healthy, or access panel is
powered
Fast flashing (5 Hz) Local communications issue
Solid System is currently healthy
ote:N Green button cover/indicator colour would be suitable for this
mode.
5.5.3 Auto-initiated alarm
Auto initiated alarms are alarms that originate from third-
party interfaces into the Sonix Io unit. Example might
include Fire & Gas systems.
Off System has NO active auto-initiated alarm
Solid System has an active auto-initiated alarm
5.6 Making a speech broadcast
Speech broadcasts on Sonix systems are made of up
three parts:
• the audio from the user (see section 6.6.3),
• a priority set by the access panel/source (see section
6.6.1),
• a zone map to define where the broadcast needs to
go (see section 6.6.2).
5.6.1 Priority
The priority within the Sonix PA/GA system is two-part
system:
1. Firstly, the activity type has a basic priority order:
a. Emergency Speech (Higher)
b. Alarms
c. Routine Speech (Lower)
2.Secondly, the audio source unit has priority number
ranging from 1 to 31, where 1 is the lowest and 31 is
the highest priority.
Warning: Priority is congured on a unit basis
and must be unique across the system to the
controller it is connected to. The Hmi-5 should
have both A & B sides, if both are in use, set to
the same priority.

5.6.2 Zoning
Before activating PTT to make an announcement, the
user can either use the default congured zones or
select the required zoning for the broadcast.
5.6.2.1 Zone conguration
Zone button and zone conguration is calculated as part
of system design, please discuss your requirements
with your local Eaton representative.
Warning: Zone mapping is built into the
rmware and is currently not congurable in
the eld.

Sonix Hmi-5 Technical Manual
16 SONIX HMI-5 TECHNICAL MANUAL TM373 / A June 2022 www.eaton.com
The available zone maps are:
Default Routine Speech Set on a project level, typically into Process/
External areas
Default Emergency
Speech Typically set to All-Call
Zone map Button(s) Configured to cover a sub-set of available zones
(Multiple buttons are allowed)
Alarm activations Set to All-Call
5.6.3 Microphone input
The microphone input on the Hmi-5 can be either a ush
mounted microphone on the chassis or a Hand-Held
microphone on a exible coiled lead.
The ush mount microphone is intended to be used
from between 8 and 12 cm from the user whereas the
Hand-Held microphone is intended to be held close to
the talker, in the 4-8 cm range.
Figure 7 - Suggested microphone positioning
The microphone sensitivity can be adjusted on request,
please contact your local Eaton representative.
5.6.4 Routine speech
A Routine speech broadcast is activated by pressing the
Push to Talk (PTT) button, either on the unit or in the
case of a Hand-Held microphone the PTT button is on
the microphone itself.
5.6.4.1 Routine Chime
The Hmi-5 can be congured 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 between
activating PTT and routing voice to the PA/GA system
while the chime plays.
Chime Name Sound Notes
Single Bong 660Hz decaying gong
over ~4seconds
The decaying gongs have the
new gong superimposed over
the top after ~1.1s
Double Bong
660Hz then 550Hz
decaying gongs over
~5.5seconds
Triple Bong
660Hz then 550Hz then
400Hz decaying gongs
over ~7seconds
None No chime
No chime is generated, and
voice is routed to the system
without delay
Table 3 - Available Routine Speech Chimes
Chime can be disabled for routine speech broadcasts.
5.6.4.2 PTT Timeout
The audio system on the Hmi-5 can be congured to
have a maximum transmit time, called PTT Timeout.
When this setting is active the access panel will cancel
the active PTT session if it exceeds the time set in the
conguration. Valid values range from 30 seconds to 120
seconds with no timeout also an option.
If this timeout event occurs, the Hmi-5 access panel
will also generate a PTT Timeout fault. This can be
used to identify situations where the PTT button has
been accidentally depressed or no longer functioning
correctly.
The PTT timeout fault can be disabled in conguration.
5.6.5 Emergency speech
Emergency speech, sometimes referred to as Important
Message, is a method for increasing the priority
of a speech broadcast, combined with a different
announcement tone. Within the Sonix PA/GA system
emergency speech is the only way to broadcast
speech over an active alarm. Flagging a broadcast as an
Important message increases its priority.
Emergency speech is selected by pressing the
Important Message button, this button is a toggle
button with timeout. The timeout is ~30 seconds since
the feature was activated or since the last Emergency
speech broadcast from the access panel nished.

5.6.5.1 Emergency speech chime
The Hmi-5 can be congured to play one of three
different chimes before each emergency speech
broadcast, the 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.
Available chimes on the Hmi-5 are:
Chime Name Sound Notes
Chime 1 1 kHz tone for 1second Long beep
Chime 2 1 kHz tone 400ms ON
400ms OFF 400ms ON Double beep
Chime 3
1 kHz tone 100ms ON
100ms OFF repeated 5
times
Multiple fast beeps
None No chime
No chime is generated and
voice is routed to the system
without delay
Table 4 - Available Emergency Speech Chimes
Chime can be disabled for emergency speech
broadcasts.
5.6.6 PTT Release Delay
The Hmi-5 has a conguration option called PTT Release
Delay, commonly called a ‘Slug Time’. This setting
makes the access panel internally keep the PTT button
active for between 1 and 3 seconds after release. This
will allow a user to correct for a digit slipping off the
button unintentionally.
ote:N Installations using both A & B side of the Hmi-5 should ensure
both sides have identical audio configuration to prevent audio artefacts
breaking onto the PA/GA system.
This feature can also be disabled by setting the PTT
Release Delay to None.
5.6.7 Mute Output
The Hmi-5 access panel has no direct outputs for
controlling speaker Mutes and speaker Attenuates,
these outputs are instead generated by the Sonix PA/GA
system rack via the Hmi Tu.
The Mute output activates when the Hmi-5 is the active
PTT broadcast on the PA/GA system. This approach
allows the user to hear any overriding broadcasts if they
are not the one active on the system.
5.6.7.1 Attenuate output
Additionally, the Hmi-5 can control a second output
intended to activate a local speaker attenuate. The
attenuate feature is provided to allow operators to
reduce the volume of an alarm in the local area. The
attenuate output, identical to the Mute output, activates
on active PTT broadcast but can additionally be
controlled manually by the user.
ote:N The Local Attenuate button has an alternative function when dis-
abled and is used to control BGM playback, but the outputs will activate
for short periods of time in this mode. See section 6.4.12 on BGM.
5.7 Fault Reporting
5.7.1 Unit Monitoring
The Hmi-5 access panel has built in status monitoring
to detect any issues early. The following features are
monitored:
• Microphone input is monitored for open (high
impedance) and short (low impedance)
• Internal Audio pathways – These are monitored using
DTMF signalling while unit is idle
• Incoming Data communications from PA/GA system
are monitored for presence and quality
• PTT is monitored for stuck switch – See section
5.6.4.2
• Inter-FPGA health – The independent halves of the
Hmi-5 communicate with each other, loss of this
communication is considered a fault
Some of these monitoring circuits can be disabled in
conguration, see section 7.
5.7.1.1 Fault reporting
The Sonix PA/GA system has a robust fault reporting
system; all issues with individual units are reported
to the 2Mx central controller using the datagram
messages. Communication links and missing units are
also monitored by the 2Mx central controller. The 2Mx
central controller then forwards the datagrams on to the
software and sends a generic fault ag back to all the
connected units.

Sonix Hmi-5 Technical Manual
18 SONIX HMI-5 TECHNICAL MANUAL TM373 / A June 2022 www.eaton.com
6 Conguration
The Hmi-5, like most of Sonix, has been designed to be
congurable via the common Sonix software interface.
For most of the conguration options for the Hmi-5
access panel, please see the Sonix Administration
Software (SAS) user manual.
6.1 Hardware conguration links
There are no hardware conguration (jumper) links on
the Sonix Hmi-5 unit.
6.2 Solo connected access panels
Hmi-5 access panel installed with a single data
connection should be installed and congured with the
following options:
• Use the A-side terminals, even if intended to be
connected as part of a B-system installation. There
are common circuits that can only be adjusted by the
A side.
• Disable Inter-FPGA fault monitoring.
6.3 Fully connected access panels
An Hmi-5 with data connections to both A and B sides
should have the followings settings/considerations:
• Priority must be identical
• Unit ID should be identical but not essential
• Enable Inter-FPGA fault monitoring.
• Ensure the audio options are identical:
• Routine Chime
• mportant Message Chime
• PTT Release delay
• PTT Timeout
• Microphone volume
• The other setup options should be the same:
• Fault monitoring
• Firmware controlled functionality should be identical:
• Available buttons
• Zoning
• Alarms
6.4 Unit ID
Each Hmi-5 access panel on a system needs to have
a unique identier, called a Unit ID or number. This
number, between 1 and 31, is used to identify the
access panel to the 2Mx central controller and SAS
software.
To read or change conguration or set the Unit ID, SAS
installed on computer and Sonix data connection cable
are required. Please see the SAS user manual for more
details.
6.4.1 Ping-set (Set new Unit ID)
ote:N It is likely that multiple persons will be required due to limited
time window to accept the new ID.
To ping-set an Hmi-5 the following procedure needs to
be followed:
1. Connect Computer with SAS installed and working to
the system via the data connection cable
2.Navigate to Hmi-5 configuration screen
3.Press Ping-set and enter a new Unit ID
Note: Unit ID’s need to be unique for Hmi-5’s on the
system, but same for A/B sides
4.Once the software has sent the ping-set command
ALL Hmi-5 access panels that receive the command
will illuminate all LEDs for ~10 seconds
ote:N If A side is powered up and Ping-set is sent to B-side only the
LEDs will NOT illuminate.
5.Pressing both left hand buttons* together on the
Hmi-5 access panel during this 10 second window
will cause that local panel to accept the new Unit ID
This is where a second person standing by the panel is
required
6.Any Hmi-5 access panel which has not had the
accept procedure pressed during the 10 second
window will discard the command and retain their
current Unit ID and configuration
ote:N The exact button presses required depend on the hardware and
firmware on the unit, but standard configuration is both left hand but-
tons together.
ote:N
6.5 Priority
Priority is set on a unit by unit basis as part of the
general system configuration. See SAS manual and
section 6.6.1 for more details
6.6 Microphone Volume
The Hmi-5 access panel has the ability to reduce the
sensitivity of the microphone.
Values range as follows:
Setting Value Gain
Full volume 15 0
Mid volume 7-2.5 dB
Low volume 0-5.5 dB
Table 5 - Microphone volume gain values
ote:N The unit must be fully power cycled after changing the volume
setting to allow the gain to be adjusted.
