The masses of the MASSes. I bet that was pretty loud.

[@matteng1997]

Man, this took me back. My old high school still has a 1990s Notifier system. The majority of the building has the same MASS ADA set to 800hz. A newer addition to the school has a few Spectralert Classics. A separate building next door is also tied into the system and has Spectralert Classics, also on the exterior. The exterior of the main building has old Simplex horns and two Wheelock 7002Ts which could be left over from an even older system that was simply integrated into the Notifier system.

[@DaSamNudge]

Just like my high school had, even down to the few SpectrAlert Classics. I wish I'd known they were replacing it a year after I graduated because I would have for sure tried to grab everything from the old system

[@joshc7348]

Lemme guess, they replaced it with L series smh

[@DaSamNudge]

@@joshc7348 sadly yes, white L-Series speaker/strobes that say “alert” and a lot of the places that used to have pull stations now just have switchplate covers

[@whelenvortexr4]

My middle school had the same system, except it was Johnson Controls branded. It was installed in 98, the classrooms had the same exact remotes, during Christmas break in 06-07 they replaced the ones in the classrooms and gym got replaced with Wheelock MTs.

[@thunderbolttdmplayz6750]

I saw a 40-50-80 fire alarm strobe on the ceiling at Macy's

[@northcutt4326]

My middle school had this exact system. It was installed around 1995-96 circa. The classrooms had strobes only. The pull stations were made by Johnson controls not notifier. The mass alarms were so unique in design and sound. They always outlived mechanical horns like the 7002T series etc. great reliable NAs.

[@whelenvortexr4]

I was happy when the Mass at my middle school got replaced with Wheelock Mts, just in the classrooms.

OOOH, WHATS THIS THING IN MY CUBBY?? OOO🤓 Blurred out* oh my god

[@siphonralarms9411]

Appealing to the MASSes I see

[@sirensofsoutheasternlouisiana]

The same smoke detectors at my school , the 2400 series!

[@burnoutteamclubbtcp7283]

The MASSes are on 800 Hz continuous.

[@user-Calebculwell]

The 90’s called. They want their notifier system back

[@joeycaridi3030]

04:48 When you said "oh no" you said in a Mario voice! Now it looks like Bowser's Koopas will arrest you and send you to his castle!

[@cnrailfan8000]

I like how all the 800hz have different pitches

[@SirensAndAlarmsOfNorthernIL]

3:30 that sounded like a Federal Signal Modulator lol

[@jeroen2010]

Can you do a video about the 2901-9846 on a 2903-9002?

[@KanoaDeCastro]

That sounds like a General alarm on a cruise ship.

[@CentralMALifeSafety]

Cool Celling Mount Classic and System Sensor Mass ADAs

[@TinyTechBoi]

Bro, I still have the same alarms in my school in December 2022😮

[@stopmotionbymg1221]

This is a job I want

[@SirensAndAlarmsOfNorthernIL]

Same here!

[@Brother_E]

Right! I was always wondering though, how would one become a Fire Alarm Inspector? Like what are the qualifications/prerequisites? I wouldn’t mind doing this as a job

[@firealarm2903_]

How old do you have to be to work as a technician

[@Sansalwayscomeaback]

OMG This is probaly exciting for me, we have these all aroud my school with very old autocall pull's.

[@bruh3120]

So your school mustve had an Autocall system before the MASSes replaced them

[@GaryBeltz]

Thee obstructed pull stations? task tsk tsk I see a fine on their horizon

[@FourtyFiftyEighty]

Indeed indeed. We wrote em up!

[@TheJakeman789]

@@FourtyFiftyEighty why? All you should’ve done was moved the stuff and said something.

[@auggatronicRoblox_official]

@@TheJakeman789 you cant just move a whole metal shelf filled with stuff to a random location without permission or whole bookshelf..

[@southwesternpasirens]

Beth El congregation has some of these MASSes and they really aren’t that loud imo

[@northcutt4326]

They are quiet. Lol

[@EndeavorsDnB]

These def don’t seem like the highest of build quality pull stations 😋🤦‍♂️
