This brings me back to my middle school days! The exact same system - an Edwards Custom 6500 - was installed in my middle school at that time. Same pulls, same horns, same panel. That system was replaced with a DSC Maxsys system in 2005, replacing the Edwards pulls with Fire-Lite BG-12s and replacing the Edwards horns with Wheelock AS horn/strobes.

These horns are old school and I like them.

The new piezo "shreiker" horns are so high pitched that many older people with high-end hearing loss cannot hear them. These old-fashioned 60 Hz. horns are much easier to hear.

Its loud. Keep in mind that I'm recording this with my cell phone so you can hear all the frequencies of the spiral arms giving. This is a lower frequency so you can hear it throughout the building and it rattles the walWhen these type of fire alarms were installed, you didn't need as many fire horns because the frequency was so low that it would penetrate through walls all kinds of stuff. Nowadays you have to have horns not only in the hallways been rooms as well so you can get the same decibel

Those old Edwards DC Adaptahorns never sound right. :P

In our science lab at the acid shower we had those type of horns

Edwards adaptahorns

Looks a lot like the backrooms, quite a trip

Bro casually does a fire alarm test in the backrooms

*KZfaq may have problems playing the audio on certain videos, this must be the one that the audio stopped working but they fixed it.*

these same 881D horns are still in use at my high school.

Adaptahorns are good if they are healthy but they are usually not reliable and always break down due to their cheap build quality

Why does this look like a backrooms level.

The library in cookeville,TN had 3 of those horns in the whole place the children’s library had one the upstairs library the other 2 Edwards pulls but in 2014 it got replaced with system sensor spectralert advances one old horn remains in the children’s library but the pull was removed

0:25 fire alarm testing in the back rooms

dame those fire alarms are louder then the ones at school

The horns run on 20VAC That why they're blowing up.

@Gb755c Edwards 881Ds. They used to be in schuminweb's middle school.

I just want horns that have different pitches. The new horns (with the exception of whoever makes the U-HNHs now) all sound the same.

Maybe out dated but still works...

Wow those things are raspy.

Those alarms sound like they are going to break.

I feel like no one did any research. This panel is almost 40 years old at this point. Back then they used lights, not strobes. Adaptahorns always sound like that. This was not a new install.

Instead of the old horns, they should put speaker strobes with voice evacuation.

the resonators are very loose on those

Needs replacement, it just doesn't sound like what a fire alarm should since it's a continual buzz, not odd enough, too ambient.

Tested that pull station wrong... What if the lever is broken lol.

2:52 that horn must have some issues

oh no! they are on FWR!

Why were the emergency lights off? (No power?)

That building sounds like it has explosive diarrhea because those horns sound horrible those horns are definitely old it definitely reminds me of my school years when I was in school I always why they would put such loud horns in portables they were so loud that it could destroy eardrums those portables always had old horns like simplex or Edward’s or any other old horns the most popular one was old simplex horns I now miss my old school days I used to hate fire drills now I’m fascinated by these old horns the 80s and 90s were the days

old est edwards adaptahorns on a est edwards 6500 panel system

Is that an 892-2B I hear around 3:07-3:15?

No strobes? There should be strobes.

This kinda looks like The Backrooms

@Ben Schumin what year was your middle school built?

At sond good mate

It has no wallpaper

EST 270A-SPO.

Where does this take place?

Sounds like me after tacobell

this must be an old system

What horns are those?

You make more video flre alarm

Sounds like an ice maker -,-

0:16 let the noise begin. They sound very weird it sounds like your in a music class with those alarms 🚨 loads of people playing instruments 🎻 🎺 🤔🙂

2:50 what the dang...

I heard a pre integrity 3:10

When was the system installed?

One word “loud”

You or u ok mate

I know you guys old old fire alarms but that sounds terrible 😫

Sounds like my garbage disposal

If there is anything more satisfying than teraring out shitty old edwards panels and installing new notifier adressable ones...i havent found it yet. Maybe not installing edwards at all...hahaha

Sounds like a mess of bees....

Those are loud adapt a horns maybe it shouldn't be in a building

is anyone else not able to hear the video?
