I recently obtained six old NFPA magazines from an antique store, and in them I found a few fire alarm add I found interesting. I will be getting them scanned later, but I figured I would share a few of the ads I found in them.

Great finds! Always fascinating to come across & read old life safety literature.
Holy … The 7500, I think it might be the first addressable system. I know Destin showed off another advert for that from 78, but thats from 74. I love seeing info about these obscure systems
This is soooo awesome!!! Great find henbasket
