OK, Now you have made yourself clear, and i understand your question, even thought you are not stating it, i will read between the lines.

It has nothing to do with station ring but co ring assignment in night mode, ok.

Yes, it will ring the page speaker in night mode if that station in the warehouse is programmed to ring on night mode on the give line you are referring to.

I have used it before and it does work.
Try putting station 100 in night mode by DND button, not automatic mode first, then work on automatic switching if you like.

Your description of what you want is not very clear.

If you done all the associated programming proper
yes, page speaker will follow ring in night mode
