- INSTRUCTIONS -
The NDR-LD Long Distance Lamp Memory System is designed for communication with remote stations
located 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. One RY-PA is required per contact closure. Additional
wires are required for extra contacts to activate external devices.
