That is the most amazing-sounding system I've ever heard.

1:45 All those horns in harmony....sounds so good

At 3:06, I finally realized how MASSive the horn variety was! XD

Omg! I love how the hallway at time mark 1:16 all harmonize together!!!

1:16 It sounds like the Carter Air Raid Siren!

Ahhhhhh.....This is what a simplex system should sound like.

I love it how theres so much harmony in the system, and then there's 2:35

I like the older alarms in this system great video

The way the alarms harmonize! I love it!

I love how they all harmonize with each other Then there's 2:35 lmao

1:15 ah, the beautiful harmony of Simplex horns...

1:13 okay but like the harmonization is insanely awesome

Nice😀👍👍 1:31 the old alarms at my high school

I love those alarms they sound great

I love the mix and match sounds

The simplex 4903-9105 4903 horn is sick

I used to jump so bad back in elementary school because of those simplex horns. They always seemed to go off on me while I was walking in the hallway alone lol. Brings back memories.

That is the most amazing-sounding system I've ever heard

1:14 Sounds Like Going To Heaven

1:15 the whole fire alarms are making a medley

Great vid!

2:36 sound grrrrrrrrrrrrrrrrr

Ahh, the Simple Horn fire alarm. Takes me back to good ol memories from Elementary school. Not the whistles the have today. oye

Wow! Nice rendition of Simplex's Symphony No.4 in G! Lovely Crescendos, Diminuendos, harmonizing, everything is perfect, even the Dischord and Cacophony movement at 2:31 !

Good stuff Zach

Interesting system...... A lot of mix and match alarm devices. Most alarms look to be Simplex Mechanical horn/strobes or lights. Definitely a nice variety.

WOW! TrueAlerts and 2901-9838's Together! My favorite and second favorite alarms on 1 system! COOL!

2:35 this is what all my mechanical horns sounds like

Love the variety of the horns, although, one can be heard sounding very hoarse!

Very cool!

2:36 Two problems: Ceiling mount on wall Very scratchy horn (At least it outputs proper candela)

Turn it up this is my mixtape

Gotta love a good Simplex system.

Did I hear a System Sensor MASS in there?

1:15 this why I love older simplex systems. Wished that newer alarms had Harmony.

Nice!

My elementary school had a very very weird combination of alarms in it in the front there was one spectralert classic, 2 bg6 pull stations, a gentex SHG 1st gen on continous, 3 wheelock 7002ts and 4 est siga 278 pull stations in the back of the school there was just spectralerts and bg-12L pull stations, and then in the pre school there was spectralerts and est siga 278 pull stations, bg 12 pull stations in the trailers and spectralerts, and ONE gentex commander 3rd generation outside and then on the front of the school there was a weathered, broken spectralert classic that would make only a very quiet clicking sound when activated

I think in some parts of my old Kindergarten School in Lake Street, MN, the alarm in the beginning was in some locations, particularly the entrance.

Ahhh. Those sounds take me back. The nurse at my elementary school said to me when I was like 6 or 7, that the fire alarm drills are only when she picks her nose. And THOSE or THOSE alarms were fucking loud as fuck man. Now these bells and whistles, swear to god thought I would go deaf. Bleeding Christ

Sounds similar to what my elementary school system is, minus to Tru Alerts. It was installed in the early 90s and is scheduled to be replaced this summer.

The old and the new fire alarm horns sound like a horror movie when they make echoing noises especially the old Simplex mechanical horn on the 4906 (I think) strobe light plate. Also, I didn’t see the System Sensor Mass. Was the System Sensor Mass a horn/strobe or remote horn? But, don’t take my word for what I am asking. Thank you for serving the fire alarm community by testing the fire alarm systems everywhere! Keep up the good work Fire Alarm Tech!

At my old elementary school there is Simplex 4903s (both 9105 and the one shown at the beginning of the video), Simplex TrueAlert Horn Strobes, and Simplex TrueAlert Speaker Strobes.

Gracias!

If you’re wondering about the alarms here it is Simplex 4903-9215/-9217/-9219 Simplex Truealerts Simplex 2901-9806s on 4903-9101s Simplex 2901-9838s on 4903-9101s Simplex 4901-9805 on a 4903-9101 Simplex 4901-9805 on a 4903-9104 (ceiling mount model) System sensor MASS or MA on a 4903-9101

Yes in simplex alarm fire is sure old system 2:35

Why is it that some fire alarms look and sometimes sound evil?

Hey, Zachary Fleck! What Location Is This?

Lovely fire drill

Imagine what would it be like if it was just 2901 9846s and 2901 9838s combo

From what I see there’s 3 4903-9217s simplex 2901-9806s on 4903 light plates 1 9838 combo and some truealerts

Sounds like my fire alarm from Camden station Elementary in Crestwood KY

I suspected at 3:10 that a System Sensor MA was in a Simplex 4903 or 2903, to replace a dead horn...

I just had a fire drill today and it sounded like that but with 9838s

Cool system! 2:36 That 9805 horn sounds very bad. Also, why are they using a ceiling mount strobe plate on the wall?

I heard a System Sensor MASS somewhere in there

This fuels my inner scotsman

What a choir

So... They actually use continuous?

can you test all of the emergency lights next?

I had those fire alarms at my pre school in the 1990's. Heard them go off almost every week in my classroom and I didn't like it.

Nice video cool

Sounds like a choir, and only one of them has the sore throat.

I love how there's a random mass lol

Does anyone know why the 4901-9805 horns sound so bad almost all the time?

2:40 that 2901-9838 sounds like heaven

My elementary school sounded like this but it was 4903 9102 and 9838s on March time

1:16 This sounds so amazing.

2:38 that is the perfect pitch

Did I hear a System Sensor MASS or MAHE at one point in the video?

Nice

Was that a gray Federal Signal Vibratone 450D in the boiler room (I saw those monster pumps, like the Vermont Achievement Center school boilers) at 3:35 ?

Nice shoes you have

My school has high pitched beaping inside with strobe lights and low piched beeping outside that you can hear at least 4 miles away

aaahhh. Simplex harmony. Exept for the horn at 2:35. It sounded like it's dying out. :(

2:36 why ceiling maunt strobe plate is on the wall and why that horn sound like it's dying.

I always wonder what is field work

Reminds me of my elementary school. Before they went to those godforsaken SpectrAlert Advances. Used to be simplex horns, edwards horns and gentex horns.

Cool

Cool nice

2:35 now that is funny

Nice! The alarm at 2:45 needs to be replaced! I feel bad for the little kids in that school. lol

1:13 Harmony starts

0:10 When you go through an emergency exit at an airport.

What model is the first alarm

Was it an ADA or non ADA MASS in there?

3:45 epic

I miss one of those horns going off

Teacher: "Tarnation! Tell them to stop that noise!"

it sounded like this in my elementary school but it was march time

Those alarms need fixed

I love simplex mechanical horns way more than the electric speaker horns

That broken alarm is there a speaker or just a piezo horn thingy in it?

The one alarm sounds like bees flying

What elementary school is this? And where is it located at?

What codes is it on

Fire alarm test in Elementary school we have a simplex 4100u control panel in the basement of the school fire alarms electronic horn strobes simplex truealerts on continuous simplex 4903 strobe plates with Electricmechanical horns strobes 2 we have 2 simplex 2901-9838s horns and we have 5 simplex 2901-9806s horns and we have 1 simplex 4901-9805 horn Sounds raspy and have a 3 simplex 2901-9846s horns sounds like a simplex 4903-9219 2 of thame and we have a simplex 4903-9219 horn strobes and there must be System sensor mass on a system remot strobes simplex truealert remot strobes The last is the basement simplex truealert on continuous and simplex 4903-9101 strobe plate with a simplex 2901-9806 horn

I hear a couple that sound like they are dying

Has anyone heard the System Sensor MASS?
