I was watching an episode where a whole lot of the tones were strung together and my first thought was "Did LA just fall into the ocean?"

@guykite3336

For 23 years I was a vol ff/EMT in the county I lived in. 28 fire stations. These tones sound just like our fire tones. Brings back memories. Tv show emergency helped me to become a fire EMT. I would do it all over again.

@badasshiker9637

There generally were two sets of tones, first and second. The tone generator would use combinations of tones that matched the decoder on a particular station. When the tones matched, they activated a buzzer, alarm, perhaps the interior lights, and in some instances where a station had an outside siren, it would activate also. I spent 31 years as a volunteer FF/EMT and knew every station's tones in my county and could name the station before the dispatcher would say it.

Those are Motorola Station Control Unit (SCU) tones. Great memories of the show! When I was a kid, I didnโ€™t know what they were earlier. Now Iโ€™m a radio tech that works on Motorola equipment. ๐Ÿ˜Š

@sosidecop64

When u hear all those tones together , you know itโ€™s gonna be a long day.

@RyuichiSakuma13

I became an EMT and then a Paramedic because of this show.  

Gage and DeSoto are forever my heroes! ๐Ÿ’œ

@frigginjiggy

Holy crap.  Reading YouTube comments has taught me more about emergency tones than I ever wanted to know.  Well done, commenters!  lol

IMO, Emergency! was, and still is, a great show.  I'm old enough I actually watched it when it was first on television.  I still watch it on Netlfix.  The positive impact this show had on the emergency medical services now provided in this country is amazing.  I don't think people today realize how much they owe to this show.

@michaellawless3401

I am a firefighter today because of these tones.

@chrisnzella

The duel tones are usually pager tones so the stations knew which stations/squads/engines were being paged. Old fashioned pagers made these sounds for the same reason. Our county here in Michigan, and other counties use them still as far as I know. Volunteer fire dept. and personal know if they need to respond if they hear their designated tones. No I don't know all about this but I did stay in a holiday express last night.

@georgedlake

As a kid, (78-79) I had the helmet, O2 gear, etc. Once we had a fire on base, just behind our backyard and I dressed up and went out with the garden hose. Once the base fire dept arrived the asked me if they could start working. That made my day. To this day I have the helmet.

@BrianGlasser

Each tone is attached to different fire stations, groups or important individuals. When the dispatcher activities a different frequency which are programmed to alarm a specific pager and to alarm the station or stations to a fire. 
There is a lot of traffic over the air from emergency apparatus conducting their work. So instead of having someone just listen to a call in our district they have a very distinct tone that alerts the staff to an emergency and hurry up.

@MrAndrewhasty21

i became a career firefighter in March 22nd 1999 because this show.

@jamesrader3329

Love those tones

@apolloniaaskew9487

Those tones are better off than the computer generated voices of today. Reminds me of the late Sam Lanier, the  real Los Angeles County Fire Department dispatcher for Emergency protecting the citizens of Los Angeles County.

@davidmack4495

we had similar tones in my dept. just south of LA...as a rookie, it was so cool the very first call I had, and these tones went off...they were eventually replaced by softer, different sounding tones so the stress level went down.

@AlanFricker-u8l

Listening to these tones brings back memories of the TV show, and the tones my dad's fire department had.  Wish I could get those tones for my phone.

@mr.shipeshafter

Engine 10, truck 10, engine 210, squad 10, engine 53, engine 101, battalion 14.
Factory fire.  225 East Crocker, 225 East Crocker.  Cross street 5th.  Timeout 01:10.

The very first emergency response call from the TV show.

@number1hvac

They are called DTMF tones.  The corresponding station radio hears the proper DTMF tone and sounds the station alarm.  Thatโ€™s why you hear the two different tones and then the buzzer go off.  I love those sounds.

@user-zf1xr5jw5c

You did a job job. ๐Ÿ‘๐Ÿ‘๐Ÿ˜„

@theonetruedoomslayer1139

I made this my alarm to wake up in the morning. Sure gets me out of bed in due time.
