Viking’s FXI-1 universal paging interface allows you to provide paging from virtually any type of phone system instead of from a microphone. You can also provide background music and electronic night bell over the audio system. The FXI-1 provides 30V talk battery for interfacing with an FXO or unused analog line input/trunk port. With the flip of a switch, the unit can connect to a FXS or PABX station ring trip port. No power supply is required in this mode. In the event that it must be connected to a “dry” 600 ohm paging port, the built-in voice activation (VOX) is in control. This configuration is useful when interfacing with systems that do not provide a paging contact closure, such as Panasonic, South Western Bell, Intertel, etc. In all modes the FXI-1 provides normally open or normally closed relay contacts to activate the central paging amplifier equipment or connect to an external background music source. After paging, the FXI-1 auto disconnects on CPC, busy signal, silence or default disconnect timer. An electronic night bell over paging feature can be activated from a momentary phone system contact closure (FXO and page port mode only).
