425Q1A Network Diagram
« on: June 26, 2014, 02:58:33 PM »
Attached is a terminal layout & schematic to the NE-425Q1A network, as used on the 500Q/554Q series local-battery sets.

This is not an official Northern Electric diagram. Just a little something I put together. I hope someone finds it helpful.
