Some Very Interesting Rare FOS Chimes…. 

The high pitched demon ones from hell are actually multitone. That’s why they have crappy chime hardware

I had both of those, I gave them to another collector. I didn’t know that they were rare.

The horn version looks like a simplex horn ngl

FOS made those, not CP, FOS/Faraday bought the company in the 90s, and then both were bought by Siemens and both went under around 2008-2010

Cool combination! What a unique chime.

I believe I've got the same device, except mine has a different white cover plate (the same as that used on Faraday/Cerberus Pyrotronics/Siemens mechanical horns, such as the U-HN-W). I think the original manufacturer is Faraday (with "FOS" being their "generic" brand), but it also seems like Cerberus Pyrotronics continued production of them after they acquired Faraday in 1995 (not Siemens though apparently). The cover was also used with quite a few other of Faraday's (& later Cerberus Pyrotronic's) alarms, including their 3-tone & 8-tone horns & horn/strobes, & a modified version with fewer grille holes was used on electromechanical horns like the 6120/Simplex 2901-9838. 1:17 I believe most electronic chimes are basically just a speaker hooked to a chime tone generator.

CHIMES!? wow didn’t know they make chimes

nice i also got my self a very rare device too

theoretically it'd be possible to make it play music

Can it do voice evac?
