The FXI-1A from Viking Electronics is a smart paging interface. It enables connectivity of today’s analog and VoIP phone systems to traditional paging amplifiers.
The FXI-1A universal paging interface allows users to provide paging from virtually any type of phone system instead of from a microphone. In addition to voice paging, it supports background music, loud ringing, and can enable a pre-page alert tone.
“The FXI-1A provides programmable features to better interface with the wide range of telecom and IP phone system variables,” said Paul Speltz, Senior Engineer, Viking Electronics, Inc.
The FXI-1A interfaces phone systems to paging systems in a variety of ways. It 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.
Background music, white noise, sound masking, or any other external audio source can be routed through the FXI-1A using the relay contacts. All paging and background audio is delivered from the FXI-1A to the paging amplifier via the 600 Ohm audio output. During an incoming page, the on-board relay will cut the background audio and trigger amplifiers for increased page intelligibility.
Intelligent features on the FXI-1A smart paging interface enhance interoperability with existing systems. In all modes it 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 to prevent tying up paging amplifiers. An electronic night bell over paging feature can be activated from a momentary phone system contact closure (FXO and page port mode only).
The minimum VOX audio signal to activate the relay for normal sensitivity is-28dBm minimum @ 1KHz; lower sensitivity it is -25dBm minimum @ 1KHz. The FXI-1A smart paging interface measures 4.38″ x 2.97″ x 1.38″ and has an operating temperature of 32°F to 90°F (humidity is 5% to 95% non-condensing).
