TALLIES
In Use Tally
This allows the system to set a tally (flashing LED) on a panel key
indicating that the port is currently in conversation with another panel
or interface. The default is disabled.
VOICE OPERATED SWITCH
There are four settings in the Voice Operated Switch section of a port’s
advanced settings which determine how the audio gate operates.
Figure 5-8: Voice Operated Switch Options
• “Audio detection off delay” determines how quickly the audio gate
closes when the operator stops speaking. Adjust this value so that
the audio gate does not close too early and cut off words at the end
of sentences or during small gaps.
• “Audio detection threshold” sets the audio level at which the
“audio gate” opens and closes. Typically the threshold value is set at
the level of a human voice, so that when a person speaks into the
microphone, the audio gate switches open to allow audio onto the
intercom line. When the person stops speaking, the gate closes,
regardless of the fact that background noise may be present.
• Recommended levels are -3dB for panels and -20dB for interfaces.
• “Audio gating” turns the audio gate function on or off. By default,
this setting is off.
This function gates (performs a logical AND) on the crosspoint and
the Vox detection threshold. If the crosspoint is made from the port
and the input Vox level exceeds the detection threshold then audio
will be passed to the port.
• “Audio presence tally” (also known as Vox tally) causes a panel’s
listen key to flash on a panel whenever audio above the set
threshold level is detected.
Also if the VOX control option is programmed this will activate when
the gate opens.
Audio Detection Off Delay
This option determines the length of delay in seconds before the audio
gate closes after the audio level falls below the preset threshold.
