0:51 why is that on a speaker?

Was there a fire or was it false alarm

My high school had these bells

0:50 that threw me off for a second

I see why they use actual pull stations..

Yep, they're REALLY loud and piercing, about as bad as System Sensor SpectrAlert Advances. The Wheelock ASes at my summer job ended up giving me tinnitus!

0:02

Ah, the Wheelock AS. Absolutely ear-piercing, yet sorta nostalgic as almost every school i went to had them! This system definitely needs some tlc.

In addition to the problems you mentioned I'd say there's another: the fact that not every signal across the entire building is synchronized, since you can hear some ASes sounding earlier than others. Given the fact that this system is so large it has NAC extenders the only course of action I can recommend to ensure all of the NAs are synced together is to replace all the existing NAC extenders with Potter's PSN-series, which can not only output the Wheelock Sync pattern but can also follow each other, making it ideal for installations like this one (though according to what I just read Wheelock's own PS-8-LP also has Wheelock Sync & follow capability, so there's another option). I'll still never understand the reason for some Simplex systems having Wheelock alarms: sure I can understand for outdoor applications since Simplex hasn't always made their own outdoor devices, but why inside? Simplex has made indoor alarms since basically the start of their fire alarm career, so why wouldn't they use use their own instead of some third-party manufacturer's? 6:56 I take it that that's one of the rooms with non-functioning NAs, right? 8:57 Not every day you see a horn/strobe & remote strobe right across from each other like that! (in perfect sync no less!) 9:41 Funny how it seems like the meditating person in the "Determination" "frame" (which don't really fit together) is holding the RSS in their left hand with the way it's mounted! 9:53 Well that's quite a big, spacious, & open "main lobby" isn't it? 10:04 Ah yes, the classic "buzz, buzz, buzz" of an older Simplex annunciator: I kinda miss the days when panels & annunciators use to buzz like that: definitely more of a gentle sound than what you get with piezos. Is that a Secutron security keypad I see next to it? (which seems to be awful chill with the alarm going off despite its fire alarm counterpart/neighbor annunciating the condition) 10:22 Interesting how they went with the kind of wall material you sometimes find on the outsides of houses (for lack of a better way to describe it). Also yeah, that outdoor strobe is _definitely_ in need of replacement given how worn-out it is! 11:02 Is that an emergency stop button I see below that AS? (in place of where a pull station likely should be. There also appears to be an emergency exit door sign below it as well (albeit mostly blocked by another sign in front of it) 11:12 If one listens closely, the sound of the panel's relays clicking to both pulse & synchronize the alarms is audible (though when it comes to the latter part how _are_ they synchronized? Do the NAC extenders have Wheelock Sync built-in or do they all have Wheelock DSMs attached? (though that would likely make it impossible to have every single NA synced together, as heard in this video).

damn those as were roaring

Jesus that must be murder for your & everyone else's ears: who's genius idea was it to use U-MHTs instead of normal U-MMTs? (set on what appear to be _continuous_ no less (are they?) At least U-MMTs have somewhat of a gentler sound as an option! Still, nice to see a pre-Wheelock Siemens system still going strong (except for the panel of course). Is that a security keypad I hear beeping around 2:27?

I could listen to fire alarms all day and be happy, but dang are those things annoying as heck

I think those are actually U-MH-MCS horn/strobes. If I read documentation correctly for them, U-MHTs were designed as temporal-only, while U-MH devices were continuous-only or coded by a NAC.

Kids in school are going to hate that sound for sure as it sounds like Tinnitus. Signals need to be replaced to Siemens rebranded Wheelock LED Eluxa horn strobes doing code-3

09:41 The Wheelock RSS is filled with Determination

Those horns are loud.

My high school tech center has Simplex pulls and Wheelock AS’ and RSS’. Panel is a 4010.

That continous slow woop is super loud

I always love seeing Simplex systems with Wheelock devices

Wheelock signals on a Simplex system? Were they reused from an old system?

I have a feeling these Wheelock strobes fail pretty commonly, unfortunately. They are popular and reliable, but it's unfortunate that they fail.

Wow! That is pretty cool they have U-MHTs there rare. Happy to see such notification appliances like that still being used I like those horn strobes...!

Very cool! These U-MHTs are not common at all! Interesting choice that they chose continuous.

Siemens U-MHTs are rare. Surprised to see them installed in a building like this.

Seems to be having sync issues between NACs and power supplies (devices on the same NAC circuit will sync but no two NACs sync with each other). May in fact even have something to do with the issue you described in the description.

I thought NSYNC was popular back then. I guess not.

Wow, they are loud

this is kinda interesting for a modern siemens system

Great video! I also have a question, which tone is these alarms set on to?

Lemme guess, did the current Cerberus pro panel replace an mxl by any chance?

Oh I know those. Siemens & Cerberus Pyrotronics has those type of horn strobes. The ones with those blue chips in the horns sound like that.

What are those set on 1200 hz

That system sounds like pain lol

I don’t remember the horns EVER sounding like that before

Why is it sounding so disgusting? It’s not a mechanical horn, mini horn, or bell. It’s an electrical horn. Electrical horns don’t sound disgusting in the FWR. Do they?

Sounds the same as the gentex gms

I hate TTS Voice Evac

"Please use the elevators. Do not use the nearest exit." - one way to go to heaven

Ther no option for downloading the rlcd panel

3:15

The message is read by Microsoft Mark and then they sped it up.

Ah yes the sound of the fire drills in my elementary and middle school before they put in the screech and strobe ones

They put the MTs on code 3 as of 6/2024

What do you think would happen if you were to wire that to an EST Genesis Sync Module? Would it sync with an EST Genesis horn strobe, or would it still do the same horn and strobe sync as Wheelock?

There is a single stroke style and vibration mechanical chimes thing which it’s kinda close to the bell though

the wheelock mt on continuous was used a lot in my state (texas). i did a fire alarm inspection yesterday at a small daycare consisting of a 90s firelite MS-4 with these alarms and system sensor 2400 series smoke detectors

Someone said if you solder it changes it back to three if you saw her

Couldn't they just have disabled the faulty smoke detector so that it wouldn't keep going off?

If you turn up your volume towards the end, you might be able to barely hear the SpectrAlert Classic horn strobe.

was this one on High Volume Medium Volume or Low Volume?
