Action
Choices are: Continuous, Slow Beep,
Fast Beep, and Pulse
Four Action choices allow the character of
the audio sounder to be selected. Select
the configuration that best fits the applica-
tion. When selected for Continuous the
audio sounder will be constant whenever it
is active. When selected for Slow Beep the
audio sounder will alternate between on
and off twice per second. The Fast Beep
pattern will cause the audio sounder to
alternate between on and off a little more
than four times per second. The Pulse con-
figuration will cause the audio sounder to
be active for two short intervals follow by a
pause. This will continuously repeat a little
more than once per second. The default
configuration for both Mode 1 and Mode 2
is Continuous.
On Delay
Choices are: Follow Call, 2 Seconds,
4 Seconds, and 6 Seconds
This configuration choice was included
as a user convenience feature, helping to
prevent the audio sounder from activat-
ing unless it’s absolutely necessary. The
Follow Call choice configures the audio
sounder to function as one might expect;
whenever a call signal is detected the
audio sounder will become active. It’s the
default setting for both Mode 1 and Mode
2 so that “out of the box” operation will be
readily understood. The other choices, de-
lays of two, four, and six seconds, are quite
unique. They support situations where an
operator is in close proximity to the Model
391 and can respond quickly to a visual
call indication without needing the prompt-
ing of the audio sounder. Selecting a delay
value will allow that person to respond to
a call request without always being an-
noyed by the audio alerting function. Only
if the call request exceeds the delay time
of two, four, or six seconds will the audio
sounder become active. The concept of
this configuration choice is that as soon as
personnel responds to a call request it’s
expected that the person initiating the call
function will stop the request. The visual
indicator is designated as the primary
alerting method with the audio sounder
only activating if the specified time interval
has passed.
Operation
At this point all connections and configura-
tion steps should have been completed
and everything should be ready for Model
391 operation to commence. An Ether-
net connection with Power-over-Ethernet
(PoE) capability should have been made.
Alternately, a midspan power injector,
in “series” with the Ethernet connection,
should have been put into place.
If desired, a connection to the line output
should have been made.
The Model 391 should have been placed
in the desired physical location. Using
the Studio Technologies’ STcontroller soft-
ware application the unit’s configuration
should have been set to meet the needs
of the specific application. The Model
391’s Dante configuration settings should
have been selected using the Dante Con-
troller software application. In this way
either or both of the unit’s two audio input
channels (Dante receiver channels) should
have been routed, by way of Dante “sub-
scriptions,” to the transmitter channels on
associated Dante-enabled equipment.
