Provide Visual Lamp Indication of Message Waiting and Ringing
The message waiting lamp retrofit kit is compatible with any telephone system with standard DC message waiting voltages ranging from 90VDC to 120 VDC. (this unit is not compatible with stutter tone message waiting indication.)
The LM-1A is fully modular for quick plug-in installation by non-telephone personnel. The unit's LED will blink at a steady rate when the message waiting voltage is detected.
The LM-1A 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.
Note: The LM-1A is not compatible with any AT&T phone system.
