While talking to Jwilson56 about phone line busy kits, I started looking around for something I can hook up to my SECU16, but I noticed most kits require a battery. Is anyone aware of a kit that doesn't require a battery? I don't need the LED indicator, just a dry contact if possible.
One of the kits I found:
