Message Waiting and Ringing

The message waiting lamp retrofit kit is compatible with
any telephone system with standard DC message
waiting voltage capabilities as well as Viking’s MLC-24
Message Waiting Lamp Controller.

The LM-1 and LM-1LV are fully modular for quick plug­in installation by non-telephone personnel. The unitswill
light in relationship to the voltage being supplied.

The units will also flicker when the phone rings, helping
to reduce noise in quiet areas by providing a convenient
visual indication for ringing or message waiting.
