The K-600D eliminates the installation of multiple bells, relays and power supplies, whenever night bells, loud ringing or emergency tones are required. The K-600D provides an existing paging amplifier with a pleasant electronic warble tone each time it receives ring voltage from an analog PABX/KSU extension.
The K-600D requires no external power supply and provides a floating 600 ohm audio output. Auxiliary N.O./N.C. relay contacts are provided during ring signal for muting, switching or operation of external signaling devices. Volume and tone controls are also provided.
