Each call station supports six area selections. Users can increase the number of areas or groups available by connecting the call station keyboard (LBB 1957/00). A maximum of 8 keyboards can be added, with each keyboard adding 7 area or area group keys.

Using the DIP switch at the bottom of the call station, different microphone gain levels, call station ID and voice filters can be selected. Service access knob can control microphone level attenuation. The LED indicator on the call station is used to display the selected area. The other three LED indicators are used to display the microphone and system activation status. Green flashes indicate standby (prompt music). Green means the microphone is activated. Amber color indicates that the system has detected a fault, while red indicates that the system is in an emergency state.
