I was about to say I have never seen those type of horns ANYWHERE before and they seem different. The fact that they are only normally used for industrial buildings would be a good reason why. They are definitely out there when it comes to devices. I'll probably never see one of these in person.

Is that an DC Adapt-A-Horn or 895B in the background on the siren video?

Niether actually. That's another Edwards 5520 D horn, one was set to siren and the other horn.

I really wanna see more DC Adaptahorns. They are non-existent in the US and I can only see them on YouTube as they seem to be more prevalent in Canada.

Weird, considering it sounded like a 895B-001 horn strobe. Why does it sound different than the other horn in the first video? I believe it is an electronic signal.

Depending on what horn it is, electronic alarms can sound different. See the Space Age Electronics VA4, Gentex SHG, Edwards 792, Edwards 892 and the Amseco motor horns.

The first video had the horn sound like a 450D. The second video had a horn in the background sound like a DC Adapt-A-Horn. It's not just the pitch, it's the overall waveform of the sound.

I can field that, where I was in the building (the basement), They have newer Edwards 5520 D horns (replacing bells), probably made within the last 10 years. The rest of the building has the ones made in the 80s.

I'll try my best, if I see anymore. They are becoming non-existent here, I knew of 2 elementary schools that had flush mount ones. One was outside my city and got demolished sadly, the other, I'm assuming has replaced their system by now.

Yeah I know they are. They seem to be very rare in the US. Funny how it is the equivalent of the 4051 and those are also getting upgraded.

The past couple days I've been replacing an old Edwards 6500 (from 1985), to a Kidde VS4 series panel. The first day we had to find EOLs, which there was 30 of them. The hardest one to find was on the rooftop, at the top of a garbage chute. Then the next day I stripped the entire 6500 out of its box, installed 2 zone cards for the 26 zones and installed metal plates as well.

Was it just the panel you changed or the notification appliances also?

Just the panel, and the EOL resistors. The bells are Edwards 439-10AWCs, in this video:

Did the Edwards 6500 FACP fail miserably like or similarly as bad as one of the FACPs on one of twoplyboy's videos? (IIRC)

Similar. That 6500 wasn't able to reset after an alarm anymore, you would have to power the entire panel down to clear it.
