I was just at the Meow Wolf in Denver, CO. It has essentially the same setup, except the devices are much more hidden among the decorations (although surprisingly in a way that still seems up to code).
That last photo: Lol. They should have moved the box down, used a separate speaker and strobe, or moved the device to the ceiling (and of course replaced it with a ceiling mount version).
Yes they have several locations throughout the us, and they are all slightly different, but they all have incredibly confusing themes and decorations. Here are some pictures I took at the Denver Meow Wolf (“Denver’s Convergence Station”):
You know, that’s the second ceiling-mounted NS I’ve seen: no idea why in both cases the installers thought it would work there given the reflector is designed for wall-mounting.
I couldn’t find any other evidence of a fire alarm system here, most Love’s locations I’ve been to don’t even have a fire alarm system. Still better than that residential smoke alarm in the other one I posted about.
