Product Details

Viking’s FXI-1A 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-1A 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 an 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-1A provides SPDT relay contacts to activate the central paging amplifier equipment or connect to an external background music source. After paging, the FXI-1A auto disconnects on CPC, busy signal, silence or page timer. An electronic night bell over paging feature can be activated from a momentary phone system contact closure (FXO and page port mode only).

Applications

Integrate your paging system with virtually any phone system
Suppress background music during paging
Provides contact closure to activate paging system if not provided by the phone system
Add pre-page tone to your paging system
