4" Color Touch Panels with Audio
Another example used with this system is that a user, upon hearing the page, could press
a button "labeled" for the source room and respond: "yes, I’m here".
FIG. 23 provides a layout of the wiring connection using two directly cross-connected CP4/A
panels that use a Master. This diagram is intended for use in general wiring information amongst
the various components of this system.
In the above example, the Master controls the volume activity of the audio being transmitted
(through the microphone on one panel) and received (through the speakers of the other panel). The
mini 4-pin AXlink cable connects the panels to the Master and the mini 8-pin cable connects the
two panels’ audio signals.
The following bullets explain what happens on the panels during an audio transmission from both
the first and second panel.
A button push on panel #1 sends a PUSH command to the Master which then:
Increases panel #1 microphone level and mutes panel #1 speaker. This allows the
first user to transmit audio.
Decreases panel #2 microphone level and increases Panel #2 speaker volume to
default levels. This allows the second user to hear the audio being transmitted from
panel #1.
A button push on panel #2 sends a PUSH command to the Master which then:
Increases panel #2 microphone level and mutes panel #2 speaker. This allows the
second user to transmit audio.
Decreases panel #1 microphone level and increases Panel #1 speaker volume to
default levels. This allows the first user to hear the audio being transmitted from
panel #1.
