I'm living in an apartment building and would like to upgrade one of two detectors in my apartment from an older hardwired detector to the new Nest Protect.
I purchased the battery-operated version of the Nest, and so would like to unplug the existing hardwired one. The wire harness appears to have positive, ground, and an interconnected wire, but the interconnected one is cut and doesn't go anywhere.
Does this mean there is no communication with a central alarm? Or will I potentially trigger a central alarm in my building by disconnecting it?
