Key Features: It has a Viking universal paging interface. You can select from FXO (loop start), FXS (ring trip) or paging port (VOX relay) interface modes. In FXS interface mode, no power supply is needed. Up to 6 units can be powered from one adapter in the FXO or VOX mode. It comes with a 30V DC talk battery for interfacing with FXO or unused phone system line input/trunk port. There's a floating 600 ohm paging output with volume control. A normally open or closed relay is available for external paging amp activation or interfacing the paging amp with an external background music source. It has an 800 Hz pre - announce page tone (on/off). It's compatible with 24 to 48 volt FXS operation. Calling party control (CPC) detection ensures immediate disconnect, and it can detect busy signal for disconnect. There's a 2.5 to 5 second VOX silence disconnect timer and programmable VOX trigger sensitivity. It has a 16 or 36 second default disconnect timer. Screw terminal block connections are provided. The wall - mount housing comes with (2) #6x3/4 panhead screws. Power options include 12 - 24V DC @ 100mA, 120V AC/12V DC @ 500mA, and a UL - listed adapter is included (not required in FXS mode). It operates in an environment of 0°C to 32°C (32°F to 90°F) with 5% to 95% non - condensing humidity. Relay contacts are 30V DC@1A, 110V

VOX time - out disconnect is 2.5 or 5 seconds, and the default time - out disconnect is 16 or 36 seconds. The talk battery is 30V DC.
Using the paging adapter is quite straightforward. First, select the appropriate interface mode (FXO, FXS or paging port) according to your needs. If you choose the FXS mode, you don't need to connect the power supply. But for FXO or VOX mode, make sure to power it correctly with the provided adapter. Connect it to the phone system line input or trunk port using the 30V DC talk battery. You can adjust the volume of the paging output as you like. The relay can be used to activate an external paging amp or connect it with a background music source. Remember to set the pre - announce page tone on or off as per your preference. When using the adapter, pay attention to the environmental conditions. It works best between 0°C and 32°C with non - condensing humidity. Also, keep an eye on the disconnect timers and the VOX trigger sensitivity settings. For maintenance, regularly check the connections at the screw terminal blocks. If there are any issues with power supply, refer to the power options provided. And if the relay contacts seem to be malfunctioning, check the specified voltage and current ratings.
