here’s some that I spotted at the totally dead Marion Centre (originally Southland) mall in its namesake Ohio city. these were installed in 1978 when the mall was enclosed. (the dual projector units were all over the hallways, while the single projector one was by the rear entrance hall) these were disconnected sometime in the 2010s when they upgraded to modern Honeywell equipment and System Sensor speaker strobes.
I wonder if these could be Honeywell rebrands
