FLARM PowerFLARM Core Installation Manual page 14

Audio OUT (pin 1) is available for hardware version 1.1 and later
Audio OUT
(FLAPFC11...), provided the corresponding feature license is in-
stalled. PowerFLARM emits 1kHz beeps on Audio OUT whenever
dangerous traffic is detected. A test beep is emitted after power up.
Dedicated PowerFLARM displays have their own sound generator
(buzzer). Audio OUT is only necessary when the buzzer of the con-
nected PowerFLARM display(s) is not loud enough to be heard in a
high-noise environment.
Electrical characteristics:
AC signal, 1.7V peak-to-peak @ 1 kOhm
Referenced to GND (pin 5), no DC bias
•
Output impedance: 47 Ohm
•
Output current (max.): 35mA
•
Connect Audio OUT to audio panels or other amplifiers with input
•
impedance between 200 Ohm and 10 kOhm. The audio panel or
amplifier should allow volume adjustment.
Do not connect a passive headset or speaker directly to Audio
OUT. If you are unsure about how to connect Audio OUT, con-
tact your dealer.
