Whelen Edge 9000 with Unitrol 480k controller

[threeofnine]

Hello,

I am new to the hobby. I just purchased a Whelen Edge 9000 lightbar and I have a Unitrol 480K controller. Could someone point me to a guild on how to pair them up? It seems the Unitrol 480K manual pdf is no longer available on Federal Signals website. What few diagrams I can find on the web only show audio connections.

The 480k installation manual is included a few pages into this PDF: https://www.fedsig.com/resource-document/file/7422
