Viking’s Universal 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.

Integrates your public address system with nearly any phone system, cuts out background music during paging,  and produces electronic night bell from ringing line or contact closure.

Performance Features

In the event a paging port is not available, the Viking Universal Paging Interface 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 analog PABX/KSU station circuit or by a common audible contact closure provided by an electronic key system.

The Viking Universal Paging Interface  features a built-in voice activated (VOX) or AC ring activated relay which provides D.P.D.T. contacts for muting background music during paging or to provide an electronic night bell. These contacts are necessary when interfacing with systems such as Panasonic, South Western activated Bell, Intertel, etc., which do not provide a paging contact closure.
