Sharing what I have so far.

I’m gathering some interesting devices for you guys. I’ll try to stay up to date with new stuff I find as best I can. I’m very busy so bare with me.

First on the list is
Edwards Adaptahorn

120 Volt
60 Cycle
0.25 Amp



eww beats

Looks like an awesome horn. I’m guessing that it has a motor in it that spins around making a tone, due to it’s shape.

I don’t think so; I’m pretty sure that AC adaptahorns output the pitch from the power line somehow. Also,

It’s a buzzer like all other mechanical horns…

Very messy. I’ll clean it all up. I hate messes. Anyway, it’s my supply room now so…

Pic of insides for mytechtime.

Other stuff. I’ll add descriptions later.

He is talking about the Beats speaker unit.

That case threw me off…
Never seen a horn shaped like that!

No. I’m lead Fire alarm tech at the World Bank in Washington DC. We have a massive Simplex System. 7 buildings networked together.

Oh, so i take it that “parts room” are all spare parts for the system, if needed?

I was quoting in agreement.

There might be a few things we could part with. :wink:

Anyways it’s cool you have extra. At my school a 4051 died and a whole month there was just wires there…

Nice collection you have so far. I hope that you can show off some more alarms that you have soon.
