Viking Electronics PI-1 Universal Paging Interface for any Phone System
 Interface your Existing Public Address System with Nearly any Phone System!
Now you can integrate any phone system with your public address or distributed amplifier audio system. Viking’s Universal Telecom/Paging Interface allows you to provide paging from any phone (or selected phones) instead of from a microphone. You can also provide background music and electronic night bell over the audio system.
The PI-1 has a built-in voice activated (VOX) or AC ring activated relay which provides D.P.D.T. contacts for muting the background music during paging or electronic night bell. These contacts are necessary when interfacing with systems such as Panasonic, SW Bell, Intertel, etc., which do not provide a paging contact closure
In the event a paging port is not available, the PI-1 can provide talk battery to allow connection of the public address system to an unused trunk input on the phone system.
The electronic night bell feature is activated by a standard ringing C.O. line, analog PABX/KSU station circuit or by a common audible contact closure provided by the phone system.
