4.4.7.1 Emergency speech chime
The Hmi-26 can be confi gured to play one of three
different chimes before each emergency speech
broadcast, the 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.
Available chimes on the Hmi-26 are:

Table 6 - Available Emergency Speech Chimes

disabled in confi guration, see SAS Product Manual for
details.
4.4.7.2 Emergency speech auto-elevate
Emergency speech can also be confi gured to
automatically activate when a pre-confi gured alarm(s)
is active on the system and PTT is activated. The list of
alarms used to allow automatic elevation to emergency
speech is set in the Important Message Elevate
confi guration option.
Emergency speech can be disabled by confi guring the
access panel as follows:

4.4.8 Mute and Attenuate outputs
The Hmi-26 access panel has outputs for controlling
speaker Mutes and speaker Attenuates, found on J9
and J10 (See Section 3.3.2 for connection details).
These outputs are controlled by the Hmi-26 and the user
operating it.
The Mute output activates when the Hmi-26 is the active
PTT broadcast on the PA/GA system. This approach
allows the user to hear any overriding broadcasts if they
are not the one active on the system.
4.4.8.1 Attenuate output
Additionally, the Hmi-26 has a second output intended to
control a local speaker attenuate. The attenuate feature
is provided to allow operators to reduce the volume of an
alarm in the local area. The attenuate output, identical to
the Mute output, activates on active PTT broadcast but
can additionally be controlled manually by the user.
Figure 17 - Local Attenuate button
The Local Attenuate button, located in the lower right
of the Hmi-26 access panel, can be used to toggle the
Local Attenuate output. The attenuate output will be
reset after any of the following events:
•
Timeout of ~300 seconds since manual activation,
•
Emergency speech active on the system,
•
New higher priority alarm being activated,
•
Alarm Cancel being activated.

The Local Attenuate button has an alternative function when dis-
abled and is used to control BGM playback, but the outputs will activate
for short periods of time in this mode. See section 4.5.6 on BGM.
