Have you ever come across a rather old building to find that it had a very modern fire alarm system?
The fine arts building on my college campus (which I’ll probably post more about at some point) was built in the 1950s and has been renovated very little since it was built. It was demolished this past summer to make way for a brand new building that will be completed in the next two years.
I’m not sure what the original system in the building was, but when I first walked into the building in 2018, I was surprised to see a 4100ES voice evac system with the new-style ES addressable speaker/strobes installed in an otherwise older, largely 1950s era building. Ironically enough, this was the first building on campus to have the new design ES speaker/strobes.
[Edit: I wasn’t able to/wasn’t really interested in salvaging the hardware. The 4100ES was actually ripped out by the school to potentially use elsewhere. I wouldn’t have been able to use the NAs anyways.]
