Just because there is an IMR label on the outer door does not make it an IMR, quite often the sign is there as a location guide for those who are unfamiliar with the site. Consider the street entrance to Down Street which has IMR on the door. To reach the IMR one must negotiate the spiral staircase, passageways and platform area to reach the IMR.
Kings Cross Picc is perhaps a more fitting example, it is an IMR but AFAIR the V frame could be worked by a signalman unaccompanied as the outer door only gave access to the frame, stick phone panel and auto telephone. Ealing Broadway similarly allows access to the frame and the telephone but the relay room behind the frame and the other equipment in the separate TD relay room which make up the IMR are inaccessible.
Kings Cross again like you say like Ealing Broadway amongst other places is separate, perhaps they should rename them SER so as to avoid any confusion to the untrained.
There is no confusion to the trained (or at least there shouldn't be), all rooms are ERs whether they are signals, comms, sumps & pumps, electrical, L&E, HT and everyone who works in them should know the difference. Over the years I worked in all such rooms on all lines. The correct solution is to train people to know the differences and understand that there are exceptions to be found.
