Recently Installed DS2000. Banging My head on the wall concerning paging. I have the door box working and the relay switch, (using co line). All extension programming, buttons (speed dial , hotlines, co lines etc... all good). I have been trying to get the external paging to work for the warehouse,(using horns and power supply) using correct pair from cpu mod. Speakers have hissing sound, (getting power) but when I try to page in to the zone, (have even tried a page all) nothing nathan notta. Was wondering if the wisemen (or ladies) here can steer me in the right direction as far as any kind of programming etc... that i may have missed. Any help would be appreciated.
