Audio Alert Output
The EFIS-D6 has an audio alert output for
sounding AOA and altitude alarms through
an intercom or audio panel. You must have
the optional AOA Pitot Probe to use this
functionality.
Connect the alarm output from the EFIS-D6 to the outside terminal of a 10 kΩ variable resistor
(not included). Ensure that audio outputs are connected similar to the following diagram. The 10
kΩ variable resistor can be obtained from Radio Shack (P/N 271-1715) or other electronics
suppliers.
To set the volume of the AOA alarm, you will need your EFIS-D6 powered on and the alarm
output wired as described above. Enter the EFIS menu by pressing any button (except the
leftmost or rightmost) beneath an EFIS page. Press SETUP > AOAALM. In that menu, press the
TEST button. While the button is held down, the AOA alarm will sound. Adjust the variable
resistor until the volume in the intercom or audio panel is at an acceptable level.
