The Viking Electronics VK-FXI-1A is a universal paging interface designed for integrating paging systems with existing business phone infrastructure. This adapter allows IT professionals to connect a paging amplifier to a phone system via FXO (loop start), FXS (ring trip), or a dedicated paging port (VOX relay) interface mode. It provides a 30V DC talk battery for FXO or unused phone system line inputs and features a floating 600 ohm paging output with volume control. The unit includes a normally open or closed relay for external paging amplifier activation and an optional 800 Hz pre-announce page tone. Disconnect features include Calling Party Control (CPC) detection, busy signal detection, and programmable VOX silence or default disconnect timers. This solution is suitable for businesses needing to add or upgrade paging capabilities without replacing their entire phone system, offering flexible integration options.
The adapter is compatible with FXO (loop start), FXS (ring trip), and paging port (VOX relay) interface modes. It supports 24 to 48 volt FXS operation.
No, a power supply is not required when operating in FXS interface mode. For FXO or VOX modes, a 120V AC/12V DC UL listed adapter is included, and up to six units can be powered from one adapter.
The integrated relay contacts, which can be normally open or closed, are used for activating an external paging amplifier or for interfacing the paging amplifier with an external background music source.
The adapter offers a 2.5 to 5 second VOX silence disconnect timer and a programmable default disconnect timer of either 16 or 36 seconds. It also features Calling Party Control (CPC) detection and busy signal detect disconnect.
