Hmi-26 Technical Manual
SONIX HMI26 TECHNICAL MANUAL
TM375 / A June 2022 www.eaton.com
4.4.6.1 PTT Release Delay
The Hmi-26 has a confi guration option called PTT
Release Delay, commonly called a ‘Slug Time’. This
setting makes the access panel internally keep the PTT
button active for between 1 and 3 seconds after release,
to allow a user to correct for a fi nger slipping off the
button unintentionally.
ote:
N
Installations using both A & B side of the Hmi-26 should ensure
both sides have identical audio configuration to prevent audio artefacts
breaking onto the PA/GA system.
This feature can be disabled in confi guration by setting the PTT
Release Delay to None, see SAS Product Manual for details.
4.4.6.2 Routine Chime
The Hmi-26 can be confi gured to play one of three
different chimes before each routine speech broadcast,
the chimes are referred to as single, double and triple
bong. Selection of a chime creates a delay between
activating PTT and routing voice to the PA/GA system
while the chime plays.

Table 5 - Available Routine Speech Chimes
Chime for routine speech broadcasts can be disabled in
confi guration, see SAS Product Manual for details.
4.4.6.3 PTT Timeout
The audio system on the Hmi-26 can be confi gured to
have a maximum transmit time, called PTT Timeout.
When this setting is active the access panel will
automatically cancel the active PTT session if it exceeds
the time set in the confi guration. Valid values range from
30 seconds to 120 seconds with no timeout also an
option.
If this timeout event occurs, the Hmi-26 access panel
will generate a PTT Timeout fault. This can be used
to identify situations where the PTT button has been
accidentally depressed or is no longer functioning
correctly.
The PTT timeout fault can be disabled in confi guration,
see SAS Product Manual for details.
4.4.7 Emergency speech
Figure 16 - Important Message button
Emergency speech, in the Sonix PA/GA system referred
to as Important Message, is a method for increasing the
priority of a speech broadcast, combined with a different
announcement tone. Within the Sonix PA/GA system
fl agging a broadcast as an emergency speech is the only
way to broadcast speech over an active alarm.
Emergency speech is selected by pressing the
Important Message button, this button is a toggle
button with timeout. The timeout is ~30 seconds since
the feature was activated or since the last Emergency
speech broadcast from the access panel fi nished.
Zoning with Emergency speech is All-Zones by default
but can confi gured to be zoned using the same method
detailed above for routine speech before pressing the
PTT button.
The Important Message LED has the following
characteristics:
•
None – Emergency speech is NOT active on the
system
•
Flashing Orange (~0.5Hz) – Remote Emergency
speech is active on the system
•
Solid Orange – Local panel is flagged for Emergency
speech (not necessarily active)
