Intercom question

Jim's intercoms are the best that I have ever had in our
Glasair. I built a beta kit of the 564 and it has been perfect. Good
volume, good squelch, failsafe direct wiring to COM1 if the intercom goes
belly up, which it hasn't. Nice product at a great price for the person who
likes to solder.

Hi All:

Is there an actual requirement that a set of jacks be installed separate
from the intercom jacks that go directly to the radio?

I had thought this was needed so that in case of a catastrophic intercom
failure the radio would still be available.

This has been present in past planes that I have owned and flown. However
I
just purchased a plane without any jacks going directly to the radio.

Before I ruin my back wiring a direct of jacks in place I ask Are direct
inputs to the radio required? If so what requires them?

Thanks
