Last month, I came back from a cruise during which I spotted a rather peculiar setup at one of the ports of call (Costa Maya, Mexico).
I visited this port last year. At that time, I had spotted a single BG-12LSP pull station (pictured below) that happened to be in poor condition. A “classic” SpectrAlert horn/strobe was mounted above it. Notice the wiring sticking out behind the pull station.

This year, I noticed that both devices had been replaced with cheap knockoff versions of the BG-12 and SpectrAlert (pictured below). I was glad to see that the non-functional devices had been repaired, but I was disappointed to see knockoff devices installed in an actual fire alarm system.
Due to the manner in which the pull station is mounted, I don’t even know if it’s possible to operate it properly. There doesn’t appear to be sufficient clearance beneath the station to allow the lever’s plastic tab to stick out upon activation.
