Table 3 - Available Routine Speech Chimes
All chime options for routine speech broadcasts can be
set in configuration, 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 first.
If the Important message input is active, then the Sonix
Io will flag 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 flag.
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 configured 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 first 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:

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 configured 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.
