Looking for Schwarse Electric catalog or Unipact bell data sheet

Fire Alarm General Discussion

Hello, I’m thinking of getting an old Faraday/Gray Unipact signal bell and am looking for catalog or data sheets about them.

Apparently, the Unipact bell aside from the Faraday brand went under a few names including Schwarse Electric, Gray Mfg, and Faraday.

It was around in 1948, and most likely up to the 1960’s.

A big feature was the one screw that mounted the whole bell on a backplate that went onto a outlet box.

That’s pretty innovative for that area.

If any forum member has or can locate info on the Unipact bell, I would appreciate it and give thanks.

It’s not quite what I was looking for, but it is interesting.

Thanks,

I forgot to mention the particular Unipact bell I saw on eBay appears to be a later one that mounts to the backplate by hooking on and swinging down ,then fastening by a bottom screw to the backplate.

I’m working on getting the picture off of eBay to post it later.
