Sonix Hmi-Tu Technical Manual
SONIX HMI-TU TECHNICAL MANUAL TM377 / A June 2022 www.eaton.com
3.2 System Status reporting
3.2.1 Unit monitoring
The Hmi-Tu has built in status monitoring to detect any
issues early. The following features are monitored:
•
Which ports are active,
•
Data faults on access panel ports,
•
Audio faults on access panel ports,
•
Audio faults on Hmi bus,
•
Internal hardware faults.
These are reserved for Eaton diagnostic use only and are
not available under normal operation.
3.2.2 Access panel audio fault
When any of the access panels ports detects a loss
of audio signal, the Hmi-Tu unit will interrupt the Sonix
2Mx Central Controller’s audio monitoring signal that is
normally passed through the unit. This will result in the
2Mx displaying fast flashing HMI fault on its front panel.

3.2.3 Access panel data faults
When any of access panel ports detect a faulty or
corrupted datagram, this is not relayed on to the 2Mx
central controller. The 2Mx keeps a record of all access
panel ID’s and displays missing units as a solid Hmi fault
on its front panel.

3.2.4 Hmi bus status indication
The red LED on the Hmi-Tu (See Figure 1 – Hmi-Tu unit
layout - Item 3) indicates the state of Hmi bus activity at
the unit:
Pattern Description
Off Hmi bus healthy, showing normal data flow i.e. top-to-bottom
Flashing red
Hmi bus in partial fault, showing reversed data flow i.e.
bottom-to-top
Solid red Hmi bus in fault, showing no data flow
Table 12 – Hmi bus status indication
3.3 Mute port
Each of the four mute ports has 2 available output
functions; Mute and Attenuate. Each function provides
a control voltage to the loudspeaker mute unit. These
connections may be used individually and as a pair.
3.3.1 Mute
The mute output is provided to prevent Larsen’s effect
(acoustic howl round) between an access panel’s
microphone and the local loudspeaker. The mute output
will be only activated when the PPT button is pressed
and has the priority to be broadcast over the system by
the access panel connected to its port.
ote: N Any overriding PA/GA system events will cause the Mute and
Attenuate outputs to be de-activated.
ote: N The loudspeaker mute unit can be controlled from either the
Hmi-26 access panel or by the Hmi-Tu; the operation will be the same.
Warning:
Hmi-5 access panels MUST use this
output to activate the loudspeaker mute unit to
prevent acoustic howl round.
3.3.2 Attenuate
The attenuate output is intended to be used to reduce
the volume of the local loudspeaker to either prevent
acoustic howl round or give a respite from a full volume
announcement or alarm tone. The attenuated level is
dependent on the set up of the Loudspeaker attenuate
unit.
ote: N The mute function will override the attenuate function at the
loudspeaker mute unit.
