Another Vintage alarm

Got this Older Beige Simplex 4050 with Dual Projector. Thing is incredibly loud. As you probably well know now, I’m into older AC devices. Just love that 60hz sound.


you should definitely share this with old school fire alarms!! i’ve never seen a faraday horn with a federal signal PR projector. I know faraday based the design of the 5400/5600 on the federal 350 and 450A’s.

One of the schools in my area has some of these, sadly I don’t know anyone at that school.

LeBron James’ HS in Akron has 6 volt 4050s with the black label! I have a post on here about it under the “what fire alarm do you have at work or school?” category.
