RTS intercom wiring

[RonKStevens]

Did anybody know how the intercom/speakers are wired on an RTS? I would like to get the microphone working, plus be able to tie in an audio system to the bus speakers

Is or used to be a guy that had one on Busnutonline a few years ago. Don't  know if any here. Also RTS Facebook page. Their wiring is marked, so if you can get a wiring diagram for yours would be easiest and best for long term use. Will need to check for year and particularly model. Also Ebay lists manuals for some at times. There may be info here for manuals too. Archives are supposed to have some, but haven't  checked them out, since I have the manuals for my 4905.

PA and intercom systems are largely transit property specific, everyone wants to do it their own way.

Another challenge...

Where's it from?

Happy coaching!

My 4905 wiring diagrams show wiring and switch locations for intercoms.
