The Westinghouse "MT" Chime

Today we take a look at a fairly familiar sounding chime. I call this the "MT" chime because that is what the community generally calls it, though that is not officially what this is called. This chime can be found on late Westinghouse and early Schindler installs. Today, I will show you the chime itself and the few settings it has. Normally I wouldn't dedicate an entire video just to a chime, but this one is one of those more unique ones I wanted to share with you!
A few examples of this chime:
Low Pitch: • The St. Louis Zoo Elev...
"Regular" Pitch: • Schindler MT Hydraulic...
High Pitch: • Interesting Schindler ...

YES I FINALLY GET TO SEE WHAT MY FAVORITE ELECTRONIC CHIME LOOKS LIKE (and now I know why the pitch varies on these.

[@alpaljl]

This was oddly satisfying!! I never knew that you could change the pitch, but it totally makes sense that you can. Man, I gotta get my hands on one of these.

[@stlelevators]

I at first thought the low/high pitch was some really rare thing, but after seeing this, I now know it's just a setting haha

[@officialSgtPepperArc360]

Wow, finally! I've been waiting forever to see the actual chime!

[@stlelevators]

This is what it looks like!

[@CenTexElevators489]

Really interesting chime, and it's too bad these chimes aren't made like this anymore, since they're so versatile with both volume and pitch adjustment. What would also be really cool is if Schindler continued to use these chimes on all of their HT fixtures, as well as 321A, 330A, 400A, 500A, and 700A elevators, along with the 3300XL, 5500, 6400NA, and 7000 elevators.

[@stlelevators]

That would be cool

[@stfplumbingelevatorsandmore]

Pretty neat! It’s also cool that it doesn’t require much to get it working.

[@stlelevators]

Most chime modules are like this. I mainly wanted to show how you can change the pitch and that Westinghouse made this chime.

[@geneseetrainselevators2448]

Very helpful as always! You are such a smart man Jason.

[@stlelevators]

Thanks!

[@ethanthecoollightnessguy8284]

One thing I like about Westinghouse floor passing chimes? Is the sound of it sounds like the Microwave bell, which is the elevators with the Dinner Bell Chime.

[@ElevatorsInternational]

I really like the sound of the chime! It’s a satisfying sound. Turning the pitch up or down, makes it sound funny, ha ha!

[@stlelevators]

I've installed this behind my button so it rings when you press the up button.

[@ElevatorsInternational]

@@stlelevators Nice!

[@baelevatorsmore728]

What’s weird is I filmed one Schindler MT with chimes that sound higher than even the standard Westinghouse chime could probably make. Maybe they used a different chime? Definitely worth looking into.

[@stlelevators]

Might have been replaced

[@TrainSounds]

Normal pitch will be at F or F#.

[@EWPA14]

For the longest time I thought the power fed to the speaker is what made the pitch vary so much. But I guess this is the real answer. Very satisfying.

[@stlelevators]

Even if it were that, it would be the slight variation in electronic components that would cause the pitch difference (specifically the resistors), not the power itself. Not all components are exactly the same. The pitch adjustment on this chime is simply changing the resistance with that potentiometer.

[@EWPA14]

Yeah that makes more sense actually.

[@Jdss22]

1:20 Imagine hering that on an MT…

[@stlelevators]

lol

[@mallguy8970]

That is a cat chime or weak chime.

[@mallguy8970]

Circuit bent!!!

[@NationalElevator]

I wish I would've seen this video earlier. To much everybody's opinion, I actually like this chime. And as other people have stated here, I always thought the pitch had something to do with the voltage put into it, not that it was a variable option. That makes me wonder if the elevator's owner could have the pitch altered at the install as a customization option? Older Dover impulses and the "epco gong" also vary in different pitches. It makes me wonder if those work the same way with a potentiometer to adjust the tone. I also love how everyone agrees that F# is the "standard" pitch lol. Anyhow, I would have an unhealthy amount of fun with one of these if I could get my hands on one haha.

[@stlelevators]

I assumed it would just be the tolerances with resistors and other components that would change the pitch. Generally you wouldn’t alter the voltage going to the chime in the field. The potentiometer is just changing the resistance.

[@mallguy8970]

This is like a Christmas decoration!!! This was first made in 1989.

[@ethanthecoollightnessguy8284]

I do also love the Schindler MT chime, it is so super cool

[@ECFE]

YES! YES! Thank you!!

[@stlelevators]

You're welcome!

[@cjelevators223]

At my local library, they have a Westinghouse "RT" modernized by Schindler. It uses this chime, and I've always wondered why it was so quiet.

[@stlelevators]

That’s cool

[@davvonmckenzie3911]

Amazing

[@baelevatorsmore728]

Cool! I was wondering what those looked like. Lol maybe you could make a song out of it.

[@stlelevators]

I tried doing that... I'm not a very musical person haha.

[@railfanningthesoutheast8318]

nice

[@ProspectElevators]

Technically "RT" chime really but if we ever find a Westinghouse MT, that be great

[@stlelevators]

There's really no name for it. I just called it that so people know what it is.

[@ProspectElevators]

@@stlelevators I see there I just simply call it late Westinghouse chimes

[@Dwall44]

Interesting. I wonder if the innovation gong chimes along with the old Epco gong chimes work similar to this one? Or how about the Otis Elevonic 401 chimes? I’ve certainly heard of varying pitches of them as well. Maybe they all operate in the same manner?

[@stlelevators]

I have some other chimes and they can only have the volume adjusted. This is the first one I've seen with an adjustable pitch.

[@Dwall44]

@@stlelevators interesting. Than that begs the question, how are there so many different pitches for the innovation chimes and the Elevonic chimes?

[@statecollegewx4060]

Are you able to do more wiring chime videos?

[@stlelevators]

Most of them are just "hook up positive to positive and negative to negative." I made this one mainly because of how you can change the pitch.

[@statecollegewx4060]

@@stlelevators oh, ok.

[@theroyaldiamondschannel7787]

Are all elevator chime box look like this or different depending on brand elevator???

[@stlelevators]

They’re different depending on the brand.

[@mallguy8970]

The highest pitch of this, I heard one higher than that before.

[@stlelevators]

I'm sure they vary a little bit on each one because the components are slightly different.

[@mallguy8970]

That was at Nordstrom in Cherry Creek Mall.

[@that_green_neko]

Now I know why the pitch bends when these things start to age. Bad potentiometers.

[@stlelevators]

Yeah that would contribute to it.

[@UrLocalSusMasterBTCP]

Are there any other chimes you can do?

[@stlelevators]

Not at the moment

[@Dana_Danarosana]

Interesting

[@stlelevators]

This was a chime that always interested me. Specifically how there were the rather rare high and low pitch chimes. I initially thought they were some rare thing, but after seeing this, I now know it's just a setting.

[@Dana_Danarosana]

@@stlelevators I'm kinda dumbfounded that it's a Westinghouse product since they seemed to literally appear as Westinghouse was folded into Schindler... and literally Westy RT got dinnerbells but Schindler RT got this chime.

[@SWFLElevators]

Oh that is so cool! The MT chime exposed! Great video! P.S. I love how you can change the pitch on that.

There seemed to be a lot of interest in this video when I made a live stream showing it.

I don't believe they are.

Nice video of the MT chimes, I have seen and heard about some Schindler MT in vegas nv

[@stlelevators]

[@baelevatorsmore728]

@STL Elevators There are three of these elevators at my college. All three have basically the same chimes and they’re all in rather good shape. One is a little low on oil though. Eventually I think TKE will top the tank off but for now it remains as is.

[@AYEItzErik06]

There are Schindler MT in Sam's Town Hotel & Gambling hall. They are traction and are a bank of 3. It looks like they are getting modernized soon because the rear elevators used to be Schindler MT, we went back this year and they are something else. The chimes on 1st & 2nd floor have been replaced, all other chimes should be original.
