What could have happened is what is called "cross-join" between the NV-EC1701

When the 1701s are in join mode, there is a key that gets generated by the 1701 and it gets shared to the other 1701(s) that are in join mode. If there are other 1701s, in join mode, that are in close proximity to other 1701s that are also in join mode, then there is the possibility of the keys getting shared to both pairs. Another way that the 1701s have been cross-joined is when they are paired to a different group than what they originally belong to. 1701s will remember the group they have been paired with until they have been factory reset. If they do not get reset before being paired to another group, they could remember the previous group they belong to.

In order to get the 1701s out of this cross join, all of the affected 1701s will need to be factory reset. Below is how the 1701s can be reset.
  • Apply power to the 1701 that is going to be reset.
  • Press the join button located behind the RJ45 LED for 13-15 seconds with a straightened out paperclip.
  • Release the join button when all 3 LEDs flash once. 
  • There should be only the blue power LED. If the BNC LED is still light, then perform factory reset again.
