NEM Lamp Memory System for Long Distances and Elevators
IF-DA-NLD and IE-JA-NLD Sub Stations
The NEM Long Distance Lamp Memory System is designed for communication with remote
locations up to 4,000' away, or to each elevator in a building. Sub stations are available in
surface or flush mount styles, and require a separate circuit board (PC-359B) to be added for
the call-in function. Three wires are required to each sub station.
