The relays are latching type.
S1 is momentary (he talks about a pushbutton) and my instincts tell me S1 is operated by an animal and the load, which isn't mentioned, may be some kind of trip wire indication.
"Has anything walked through here?"
"If so did it leave?"
I don't know why I think this.
It might be my ESP.

IIRC the author doesn't go into the "why" but I think it would shed a whole lot of light on his motivation.

If I wanted to know if a bear had walked into a cave using a pressure sensitive mat as a trip wire and was still in there I might want to use this circuit.
If I query the latch and it hasn't been reset by the bear walking out I might just wait.
Maybe, instead of a bear, a couple of meth-heads are in my cave.
Dunno, just guessing...

OK, to be honest, I quickly gave up figuring out this contraption.

Could be the author doesn't know the "why", his motivation being to have somebody figure out for him.

OK, I get it now:

Uses -6 dB line receivers to eliminate resistors, board space etc.
Could be made with 2X THAT1246 or a single SMT THAT1286.

Thanks for posting Jacko.
