One detail question from a non-alarm guy: why run an 18-2 from the house to power a siren? I'd think if there's local power to run the zone expander, that could run a siren. I expect the enclosure has a backup battery, so power loss isn't an issue, at least not immediately. Was this perhaps to run a siren signal from the outbuilding back to a siren in the house to alert the main house? In which case, why not a dry contact?

A good answer is easier with a clear question giving the make and model of everything.
