Eaton SONIX Io Technical Manual

13Sonix Io Unit Technical ManuaSONIX IO TECHNICAL MANUAL TM366 / A June 2022 www.eaton.com5.4 Other PA/GA system status outputsThe Sonix Io unit has following general outputs, drivenfrom the Sonix PA/GA system.5.4.1 Fault outputsThe Sonix Io unit has 2 fault outputs, Global Fault andProgram Fault, also known as Major and Minor faultsrespectively. The source of the faults is chosen by the2Mx central controller, with the Global fault activatingon any issues with the system and the Program faultnormally restricted to a subset. These faults can bedisabled 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 yourrequirements.5.4.2 Entertainment and Auxiliary MuteThe Entertainment and Auxiliary mutes activate on anybroadcast that is above Routine Speech, i.e. Alarmsand Emergency Speech. It is intended to silence anyentertainment systems, such as background music,televisions or private cinema, and allow any broadcastmessages to be clearly received.Polarity is configured using external links, see section4.6.2.ote:N Entertainment Mute does not activate on routine speech.ote:N Auxiliary mute follows the same pattern as Entertainment muteand does not activate on routine speech.5.4.3 System BusyThe System Busy output is activated whenever thesystem is no longer idle, i.e. during Routine speech,Alarms and Emergency speech. This includesbackground music. Any testing activity like sense testsand Ticktone (See 350-d amplifier manual for moredetails) are not included.5.4.4 Ships WhistleThe Ships Whistle output is intended to be connectedto third-party equipment, typically the collision alertwarning or international maritime destress on vessels,to allow that system to be activated when an alarmis running. The alarm, or multiple alarms, it will beassociated with, are set as part of Sonix Io configuration.The output can also be configured to pulse in sync withthe alarm cadence.ote:N Cadence options only impact output when selected with inter-rupted alarms.Please see SAS manual for more complete configurationdetails.5.5 Other PA/GA system control inputsThe Sonix Io unit has the following control inputs intoSonix PA/GA system.5.5.1 Alarm CancelThe Alarm Cancel input generates a short, approximately2 seconds, active pulse when the input is first activatedand will only re-trigger if the input is subsequentlycleared. This is to prevent a fault on the input fromlocking 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 AttenuateThe Alarm Attenuate input is also an edge triggeredsignal. Each new activation will cause the system tochange state between full volume alarms and attenuatedalarms. Attenuated alarms can be disabled elsewherein the system and the input will only have an effect if analarm is currently active.ote:N Activating this input with no alarm will generate a short indicatorevent on any Sonix Hmi-26 access panel connected to the system.5.6 Fault monitoring and reportingThe Sonix Io unit has built-in fault monitoring for thefollowing 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 monitoringAll faults are reported into the Sonix PA/GA system viathe 2Mx central controller and the Sonix AdministrationSoftware (SAS).
