Is there such a thing? I have a customer who wants a heat detector in a barn but wants the siren to be on the outside of the barn. Is there such a product? Otherwise I figured I would just use a vista 20 with a siren and wired heat detector.
I would go the Vista route and your choice to use a siren driver or not depending on how loud customer needs the siren to be. A detector that has a built in siren might not be loud enough.
