The K-600F eliminates the installation of multiple bells, relays, and power supplies, wherever night bells, loud ringing, or emergency tones are required. The K-600F 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-600F requires no external power supply and provides a floating 600 ohm audio output. Paging In and Out terminals are provided to allow automatic switching between paging and warble audio when used with an existing paging installation. A set of N.O. / N.C. relay contacts are provided that switch in cadence with the ring signal. Volume and tone controls are also provided.
