SONIX HMI-5 TECHNICAL MANUAL

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:

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

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.

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
specifi ed as part of unit ordering.
