Viking Electronics PI-1A Paging interface

Viking’s Telecom Paging Interface allows you to provide paging from nearly any phone system instead of from a microphone. You can also provide background music and electronic night bell over the audio system.

The PI-1A features a built-in voice activated (VOX) relay which provides DPDT contacts for muting background music during paging. The relay is also activated by AC ring for providing electronic night bell. These contacts are necessary when interfacing with systems such as Panasonic, South Western Bell, Intertel, etc., which do not provide a paging contact closure.

In the event a paging port is not available, the PI-1A can provide talk battery to allow connection of the public address system to an unused line/trunk input on the phone system.

The electronic night bell feature is activated by a standard ringing analog PABX/KSU station circuit or by a common audible contact closure provided by an electronic key system. The ring pitch and volume are adjustable allowing you to differentiate between multiple ringing lines.
