I'm installing an Ademco Vista 15P panel in place of an old Napco system. The Napco unit had a built-in siren driver, which was connected to a couple of speakers in the house. It looks like the Ademco doesn't have speaker drivers, as best as I can tell. My options appear to be either to get a separate siren driver or replace the speakers with Ademco (or equivalent)sirens. Is this correct, or am I missing something?
Thanks for your advice,
Rob Houston
