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.

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 configured using external links, see section
4.6.2.

Entertainment Mute does not activate on routine speech.

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 amplifier 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 configuration.
The output can also be configured 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 configuration
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 first 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).
