Provide Night Bell Over your
Existing Paging Amplifier
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 a C.O. line or
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 in cadence with
the ring signal for muting, switching or operation of external signaling devices.
Volume and tone controls are also provided.

Operation
Upon detecting standard AC ring voltage on the LINE INPUT jack, the K-600D will produce a 600 ohm warble tone in
cadence with the ring signal. In addition, the normally open contacts will close and the normally closed contact will open.
