Miriam Hospital which I have become VERY familiar with from my grandfather’s illness and eventual death in 2014 to my grandmother’s illnesses, has a mixed system. Some parts (I assume these were newly renovated) have Wheelock E70S and other parts (I think the older parts) have Simplex 2902-9234 chimes on 2903-9101 light or strobe plates. A few months ago when my grandmother was admitted, we came in during the tail end of a fire drill. I could only hear the chimes and nothing from the speakers.
