Fire Alarm Activation #6

- Опубликовано: 31 авг 2022
- Note: This was an announced fire drill, most drills are unannounced. Please don't ask why I was running, I don't know myself why.
A large variety of notification appliances sounding on a Notifier system at a high school. The previous system was probably an old Edwards/EST system given the numerous 892 series horn/strobes throughout the building. The non-Edwards/EST devices scattered throughout the facility likely replaced defective devices after service switched to Notifier. It's a very unique system encompassing various devices of different ages and manufacturers.
Components:
Unknown Notifier FACP
Edwards/EST 892 series Horn/Strobe
Wheelock MT-24-LSM Horn/Strobe
Wheelock NS-24-MCW-FR Horn/Strobe
System Sensor P1224MCR Horn/Strobe
System Sensor P2(4)R Horn/Strobe
System Sensor P2(4)RK Weatherproof Horn/Strobe
Signal coding is continuous for most devices, with newer devices in temporal (code 3). System Sensor devices likely run on their respective strobe synchronization, but it is hard to tell due to the mix of incompatible devices.
Below components are not seen in this video.
Wheelock Exceder HSR Horn/Strobe
Wheelock RSS-24MCW-FR Strobe
Edwards/EST 270-SPO Pull Station
Notifier NBG-12 series Pull Station
STI Stopper II Pull Station Cover
System Sensor 2W-B i3 Detector
Notifier FSP-851 series Detector
Unknown Edwards/EST Detector

I'm impressed. A video of 892s that have different pitches.
Very interesting system. My elementary school had (and still has) Edwards 892’s paired with 270-SPO’s! Not too long after I started 2nd grade, TrueAlerts were added on, as a 4010 likely replaced an older Edwards panel. There are also a few System Sensor and Wheelock NAs replacing some 892’s and a BG-12 replacing a 270-SPO. In the relocatables, there are a few 892’s and 270-SPO’s, a couple of 278B-1110’s, and some 757-5A-T’s.
I wonder why they didn’t just replace the entire system with truealerts, but this did happen to one of my districts elementary schools though
My middle school used to have 892s with an addon with UMMTs, a few years ago, the parts with the 892s were added on to the Siemens system that the UMMTs are on and the 892s and the other old Edwards devices were replaced with ZH-MC-Rs and new Siemens devices. the existing Siemens devices remained and surprisingly didn't get replaced because some of the smokes are looking a little beat up and the UMMTs have trouble syncing with the rest of the system
Damg those Wheelock MTs flash fast. My school has a mix of Gentex Commanders, Gentex SHGs, Wheelock MTs, and Spectralerts
This is my high schools fire alarm system in a nutshell, except I think they are all on code 3, I haven’t had a fire drill there yet.
It’s a mixture of random spectrAlert classic and advance horns and a bunch of old horns in which some are simplex
That's pretty cool! It's hard to find old Simplex devices where I lived. I know the town library had 2903s, but there's a chance those got replaced.
@@dewpoint8900 My school also has old wheelock horns with a weird cover on them, also my school does have a few 2903’s, one 2903 horn in the choir room, and a few 2903’s with strobes in the school annex
@@dewpoint8900 I was messing around with a voice changer I had and found an effect that actually turns an Edwards integrity into a Spectralert advance, the effect is called “Human Whisper”
@@dewpoint8900I forgot to mention that all the 2903’s and old horns are set to continuous, everything else is code 3.
2:57: this is what the old horns sound like
cool mix. we have:
Edwards 892 Horn/strobes
Spectralert Classics
Wheelock NS's
Spectralert Advance
Wheelock MT's set on Steady Horn.
this is very interesting! my middle school, built in the 70s, had these at 0:58 (i don't know the exact name), and they are VERY loud in person, at least the ones at my school were, thank you for posting these! gives me very "fond" memories :)
Very interesting, my elementary school had at least two of those edwards 892s (In music and band classrooms) but they were most likely disconnected for reasons. Still an amazing video, I love seeing these in action!
My middle and high schools where the only places I've seen these in-person. I just happened to get one from Ebay recently.
@@dewpoint8900 Lucky, my district is obsessed with keeping them disconnected in their buildings for some reason
Ever ask to pull it? My school always lets me pull theirs and reset the system.
what could have been behind those big grills where the newer alarms are? some giant old bells?
One 892 kinda sounds like a 4903 9219
That is really loud
Nice
Wonder why they just didn't put the new panel on temporal code 3?
I actually think the mixed coding and devices makes it unique
Could be any number of reasons, if I had to guess:
1. This panel was installed before code-3 was mandatory. Any devices you see doing code-3 probably do so internally.
2. The majority of devices is this system are Edwards 892s, which I rarely hear use any coding aside from continuous. Although they have separate wiring for the horn and strobe, it's possible installers were lazy and didn't bother separating these into separate NACs.
3. The system is grandfathered. Therefore, the 892s can stay in continuous. These devices are definitely not ADA or code complaint, so I have a reason to believe they are grandfathered.
Was that a system senser classic?
There's several, yes.
