These are the exact devices at my high school!!! They have black labels (first generation) and 5001/2 projector horns, which are used on IBM/Simplex 4200 systems. The ones with the silver labels are the second generation versions and are used on 4207/8 systems. There is one 4050 with an “hourglass S” label (3rd generation) from 1978-80, which is used on 2001 systems. This unit most likely replaced a dead first generation one. Check out my fire alarm system tour video!

Edwards also makes a tri-volt transformer that can do 6, 12, and 18 volts AC.
Nice to see you back! That 4050 sounds great!
Sure does sound great! Glad to see you around too!
1:04 Its walking! Nice vid
You got that right! Thanks for watching/commenting.
I'd knew you find a better adapter one day.
Good to see you once again!
Glad to be back for once! Yep, the adapter was sure a lucky find.
Email me if you wanna trade alarms; not necessarily this one, but something AC as I have a rare one that I don’t necessarily wanna keep.
Welcome back
Thank You!!
i have a AV-32 and that alarm is perfect for it. the one i currently have for it sucks. the reason is it does not fit the alarm well.
