4.5.5 Global fault reset
The Sonix PA/GA system has ability to allow faults to
‘reset’ or be cleared remotely. This does not change the
state of the system, i.e. doesn’t cancel any active alarms
or broadcasts. Please see the 2Mx controller manual for
more details on fault reset. This feature is useful when
system cabinets are in a restricted space.
To action a remote fault reset, the Hmi-26 unit must be
configured to send the ‘Global fault acknowledge’ by
setting it to enabled. This feature is useful in situations
where a fault has already been rectified but the system
is showing a historical fault (Flashing Red health LED) as
it allows the clearing of the historical issue.
Once enabled the procedure for remote reset is simple:
press and hold Fault Ack for approximately 6 seconds or
until the system Health LED goes green.
ote:
N
Any faults still present, such as a split loop, will not be cleared by
remote fault reset, the fault will be re-engaged within a second.

4.5.6 BGM (Background Music)
Background music is an optional feature of the Sonix PA/
GA system, its management and control are not covered
in this manual but the local attenuate key is re-purposed
to allow remote control of BGM.
To enable an Hmi-26 access panel to control BGM
the Local attenuate key must be set to Disabled in
configuration. This prevents the local attenuate output
from activating when the button is pressed.
ote:
N
Local Attenuate output will still activate on both PTT and for ~1
second on activation of the button.

4.5.7 Engineers Panel
An Engineers Panel is intended to activate a single
side, A or B, of a system to facilitate fault finding
and performance monitoring without the other side
interfering/confusing the diagnostics.
An Engineers panel activity has a different priority
than a normal access panel. Both alarms and routine
speech sit below any other input on the system bar
background music. This has the practical application that
an Engineer’s alarm can be overridden by routine speech
broadcasts from another source. Emergency speech
from the Engineers’ Panel is positioned like a normal
access panel in the priority list, that is just above alarms
but below other access panels. This allows the panel to
broadcast on the system in the case of a non-Engineers’
alarm being active. The Sonix feature, AB+, is designed
to distribute inputs from one system to the second to
allow any missing inputs to active the entire PA/GA
system. This feature would cause an Engineers Panel
to broadcast on all speakers and beacons, defeating the
purpose of the Engineers Panel, except that the Sonix
Hmi-26 has a special priority value which prevents AB+
interfering with Engineers Panel operation.
The Sonix PA/GA system has been designed to allow a
single Engineers panel per 2Mx controller. If an Hmi-
26 unit is intended to be used as the Engineers Panel,
it MUST be configured to have a priority of 2 (its unit
ID is not important). It must also be connected to local
system ONLY. Eaton suggests that only the ‘A’ side is
connected no matter whether to an A or B system, but
this is not essential.

4.5.8 Ms12 Remote initiation
The Hmi-26 access panel can be used to remotely
initiate a message recorded on the Sonix Ms12 unit.
The remote initiation can only play a message that is
already loaded and is not disabled in the configuration.
Please see the Ms12 manual for further information and
instructions.
To initiate playback, first press the Ms12 (sometimes
labelled as ‘Monitor’) button, then press the zone button
corresponding to the message required. If the system
is busy then the Ms12 can be configured to ‘queue’ the
playback request until the system is available or the
request times out, see the Ms12 manual for details.
The zoning for the message playback is set in the Ms12
configuration and cannot be dictated from the Hmi-26.
The Ms12/Monitor button can be disabled in
configuration, see SAS Product Manual for details.
