Simplex 4050-80s on a 2001!!!!! | Fire Alarm Test #45

[@YourLocalFireAlarmTech]

absolutely beautiful!! It's amazing to see systems this old still in service. It's a shame newer ones arent this cool lol

[@johndeerefan725]

Cool finding 4050-80s still in service, even though most of the lights are blown out. That horn at 2:15 sounds sick, though. Hopefully, they'll slap new bulbs in those 4050-80s, but cool find though on a late 70s system.

[@dashcamandy2242]

Hi! 👋 Came here immediately after the Techmoan video, following your link. This video is proof that vintage Simplex systems really do stand the test of time!

[@FourtyFiftyEighty]

@@dashcamandy2242 indeed they do. The 2001 has to be my favorite panel of all time

[@willbill808]

What a lovely mid-late 70’s system.

[@neohistoryfan1014]

You should salvage this system if it's due for replacement anytime soon. Be sure to salvage the backboxes for the 4050-80s. I guess you could become the Old School Fire Alarms of the Spokane Valley.

[@aidanthetoiletelevatorfire7554]

This system is a gem!

[@raizrindustries]

That's an awesome system to see still in service! Seems like a lot of the 4050-80's bulbs are burnt out though.

[@PhilLove531]

Those alarms sound cool

[@firealarm2903_]

Great video and absolute classic system!

[@sugamusic6477]

Woah, the horn at 2:14 sounds messed up!

[@Fahrenheit4051]

Those are 4050-84's! Too bad most of the bulbs are burnt out, but awesome that the capacitor is still good on the 2001.

[@FourtyFiftyEighty]

No they’re 4050-80s. The March time card is making them blink on and off

[@electromaniac5573]

@@FourtyFiftyEighty so do you just replace the bulbs or do the devices have to go?

[@NSOX18]

the 4050-84/5's don't flash like that , They actually dim but dont turn off.

[@officialsimplexguy]

@@NSOX18 yes they do. They just flash at a faster rate so the light hasn’t fully drained its power before it gets turned on again.

[@ZakWolf]

@@FourtyFiftyEighty, yep, many 1970s Simplex systems using 4040-60s or 4050-80s were configured with one NAC sounding the horns on Continuous and another flashing the light plates.

[@Earth_Number_12]

I bet that all those alarms got replaced with Advances

[@ZakWolf]

You mean like what happened at my school that also had Simplex 4051+4050-80s? 😛

[@JBF-GST-Tanda]

2:15 What's the ￡@@k...... The sound of HELL

[@ZakWolf]

Interesting seeing an early Simplex 2001 system with the NACs set up like a Simplex 4208 or 4207 system, i.e. the horns on Continuous and the light plates flashing (via the March Time card, compared to the coding wheel on a 4208 or 4207 panel). It seems 4251-30 break-glass pulls were pretty popular on school fire alarm systems in the 1970s and 1980s. The elementary (now K-8) school I went to for kindergarten is such an example. The 4051s here even sound a lot like the ones that were at my school, but they did Slow March Time (apparently the system coding was changed in the 1980s or very early 1990s, because when a friend of mine went to the school when it was brand new in the 1970s, it was configured so, again, the horns were on Continuous while the 4050-80s flashed).

[@Brendy_KXZTOffical]

1:43 - One strobe still survived!

[@ZakWolf]

It's not a real strobe. In the words of Sheriff Woody, "It's a little light bulb that blinks!"

[@Brendy_KXZTOffical]

@@ZakWolf good to know!

[@eggfriedrice-gj8jc]

It's the best day ever I got a new car and you upload a video

[@zaiprotoneti]

the 4050-80s were my fav!

[@Loganetics1]

[@shred_YT]

This is the same setup as my elementary school. All the 4051 horns were in continuous and the strobes were in march time flash. The only difference was the tone in all the horns were in the same pitch instead of different pitches like the video. It used to terrify me as a kid and the fire drills were painfully loud.

[@ZakWolf]

Yeah, the Simplex 4051s at my first elementary (now K-8) school were also extremely loud, but the pitch varied like in this video, and they were on 20bpm March Time during my time there.

[@alexgilbert2]

AMAZING SYSTEM!!!!

[@burnoutteamclubbtcp7283]

Whoa! Simplex 4051's!!!!!

[@Goldenrod636]

Were some of those 4051s in classrooms because I swear some of them sound like there is only 1 alarm in the area.

[@sandiegotrafficlightstrain354]

Why not just put new bulbs in the burnt ones.

[@achannelwithnopurpose1977]

If it’s all gonna be replaced soon, which judging by the state of most field devices it prob will, get chasing on those parts. Everything can all easily be refurbished and then you have all the 4050-80s you desire.

[@brandonkonicki2177]

Guess the alarm company didn’t remove the old horn only and looks like then system didn’t pass inspection all the lights were dead but just one worked. Hopefully they get a new simplex system that would be a good video

[@kansasstatealerting2874]

This is amazing!!!

[@CJWJR]

Are these so old that there are no replacement light bulbs for them?

[@1996ChevroletImpalaSS]

Do you know what year was the panel installed?

[@FourtyFiftyEighty]

I want to say 1979 or sometime around then

[@1996ChevroletImpalaSS]

@@FourtyFiftyEighty makes sense

[@ZakWolf]

@@FourtyFiftyEighty, yeah, it would most likely be around 1979-80. (Simplex was still installing 4051+4050-80s in 1980, most likely to clear out old stock with the 2903 series' introduction that year.) Heck, it could've even been from 1978, since that was the year Simplex first launched the 2001 series of panels. (But I've also seen quite a few Simplex 4207 installs from 1978.)

[@MacksAnguiano]

Save the 4050-80’s!!!

[@user-Calebculwell]

Legendary system! ( why are the lamps not blinking )

[@Alwaysdoinit112]

0:56 what's that other 4051 doing there?

[@piktureit]

It’s actually a bell behind a 4051 trim plate.

[@sethhorst6158]

I'm curious if light bulbs for those are still obtainable?

[@FourtyFiftyEighty]

Yeah they’re just standard bulbs

[@ZakWolf]

@@FourtyFiftyEighty They're the same bulbs also used in Simplex's 2903 and 4903 light plates and the Space Age AV32 and AV32 light plates (all the 24-VDC models).

[@anthonymeza7519]

We got a broken horn and light don't work

[@ZacharyHappy366]

Hey 4050-80 what happened to the break glass hammer on 0:36 + 0:49 where’s the glass

[@michaelgrahamwongacutemadness]

Probably broke

[@ZakWolf]

@@michaelgrahamwongacutemadness Some of the 4251-30 pul stations at my first elementary (now K-8) school ended up looking like that over time. A few also had the break-glass frame and hammer removed like at least a couple of the pulls there. First time I saw one at my school looking like that, at first glance I thought they replaced it with a new 2099-series pull station until I noticed the old "SIMPLEX" logo and the holes above the lever.

[@pentiumman3338]

Did you conpose the intro music from scratch, or did you use loops?

[@FourtyFiftyEighty]

From Scratch

Weird how they only wired the lights to the march time card not the horns

[@FourtyFiftyEighty]

It was apparently pretty common back then

[@officialsimplexguy]

@@FourtyFiftyEighty I know it was on 4208s. Didn’t think it was on 2001s especially since both the horns and the lights are 24vdc
