LM-1A
Message Waiting LED
Lamp Retrofit Kit
October 14, 2008
The message waiting lamp retrofit kit is compatible with
any telephone system with standard DC message wait-
ing voltages ranging from 90VDC to 120 VDC.
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 flash when the phone rings, helping
to reduce noise in quiet areas by providing a convenient visual indication for ringing or message
waiting.
Notes: 1. The LM-1A is not designed to recognize stutter dial tone from any ana-
log telephone company phone line or PABX. 2. The LM-1A is not compatible with any
AT&T phone system.
