Provides a set of 20-->30 A contacts direct to the horn. The relay can be
actuated
via some small gauge wire since it probably requires only milliamps.

I've done it many times, never hurt a working horn, BUT it probably
does not extend its life any either.

Like you, I don't know everything, that's why I'm married, she DOES!
Voltage from a source be it direct or thru relay contacts if of significant
current (amperage) should make the horn work.
I suggest you wire them in parallel, from the hallway walls to your door bell,
I'm sure she will be very pleased with that :)
