So--- embarrassingly, I figured out the beeping source. It was the gyre unit submerged directly below the light. Something was stuck. I disassembled and reassembled and then reset everything and the beeping stopped. I did contact AI in between writing this post and fixing the issue, they claim that they have never heard of one of their lights beeping before (which in my case makes sense), but I wanted to let others know, since this seems to be an issue others are having anyway. I am having a separate issue with the AI hydras-- the red LED seems to display differently across the parent-child combo. I have them paired and have been replaced twice by AI already. The diodes were fine from September up until recently. Maybe this should be a different post, in any case wanted to let you know the resolve.
