It seems like out of all the multi tone devices out there, the MASS got set to slow whoop the most often. It’s neat to see them on a Simplex system. Kinda reminds me of one of my college’s buildings, but it’s classics on Simplex and TrueAlerts.
Cool video! These System Sensor Masses were all over my elementary school, also set to slow whoop. They actually used to scare me so bad that one day, I actually refused to go to school because of them.
Interesting how Simplex used the MA/SSes back then for their multitone option. Hearing all those un-synced MA/SS slow whoops reminds me of another member here that lived in an apartment building with such a setup. It was a Notifier System 5000 installed in 1991, replacing an old Simplex 4208 or something, and they removed the Simplex 4040 horns and slapped the MA/SSes with trim plates right onto the 4050-82 light plates, looking really awkward. The apartment units also had PA400R mini-horns installed, and he remembered how they would sound first, followed by the MA/SSes a few seconds later.
The alarms sounding for a trouble in walk test is for devices that can’t create an alarm condition, but are monitored. The alarms sound for confirmation that the device’s monitoring status can be updated
There was a video by NewAgeServerAlarm recently about a radionics fire and security system. The supervised bell circuits on such a system are supervised by a zone. To test a zone like that, an alarm may not be possible, so a trouble condition; created by silencing the bell circuit, is treated like an alarm
My elementary school had those in the original 1957 part and in the 92 addition, it had 2901-9838s on retrofit plates. Summer of 2019, it was all ripped out and replaced with a 4100 ES with Tru Alerts
The person who selected that tone when this system was installed is evil! That sound would put the fear of God in anyone and drive them into a wild panic!
Me: “May I have your attention, please. There is a fire emergency reported in the building. Please leave the building by the nearest exit. Do NOT use the elevators!”
Even though this system is actually in good shape despite the walk test error, is it still up for equipment replacement? I personally don’t think it’s ready to replace as it works well.
@@FourtyFiftyEighty Did they fish this system’s components (panel and field devices) out of a warehouse in “new/open box” condition (reason why i asked that was because that’s what my old school district did with their newest EST3 install which used old unused parts they left in a warehouse)? Or is it actually because the school is the newest school in that district?
PNW has some real old systems with Idaho being next to WA it does not shock me. Portland, OR has some schools with 120v Nac circuits. WA has tons of old systems.
Masses on A Simplex System; Interesting, but I kind of like System Sensor Devices on Simplex systems rather than the usual Fire-Lite. Simplex is a lot better than Fire Lite in my opinion. These do sound a little scary on slow whoop, but other than that it was an amazing MASSive test

The non sync slow whoop sounds horrifying and amazing at the same time.
Man, I love slow whoop MASS. Honestly they have the best slow whoop of all US alarms with it as an option imo. Its always cool to see them!

I felt the same, but it was 9833s that I was afraid of.
Great video. System Sensor Masses used to give me the creeps in middle school. They were all in slow whoop to.
I love the slow whoop those alarms make
It's the fire alarm equivalent of a Shepard tone! It just keeps rising and rising forever!
Nice! It’s a little scary… but a awesome tone on the System Sensor MASSes!

I love the slow whoop mass
I had those in school, and i absolutely terrified me of fire alarms, and still to this day, it gives me goosebumps listening to this

Nice! It’s scary when hearing this by yourself and I like your videos and subscribed to you
I remember this tone from the masses at my middle school and how much it terrified me
These are the fire alarms that we have at my school and they have the slow whoop too
Me: “May I have your attention, please. There is a fire emergency reported in the building. Please leave the building by the nearest exit. Do NOT use the elevators!”
what a horrifying noise.
They sound like the slow whoop tone or medium sweep but slower on an apollo sounder

this one is not as of now. Its actually shockingly the newest system in the district

no......... it was installed in the late 1980s@@achannelwithnopurpose1977
were old alarms bells or horns
uhh these are the original alarms
ur in idaho?!?!!
No. Im near enough to do some inspections there though

What are the original alarms?.
Not a fan of them combining these alarms with a 4002
i wonder why they didnt install mechanical horns when it was installed in the 1980s
Why simplex with system sensor?
Same place again
Sounds like Star Trek II.
Not a really interesting system but if I was in that building when the alarms went off I would definitely haul ass out of there.
