Video on going in depth explaining how the smoke exhaust and pressurization fan system works and why it’s there czcams.com/video/uv8BTbXV5uQ/video.html
I was supposed to get a school like that but it never got passed sadly At least my current high school actually has many kinds of alarms. In the school itself it has a different model simplex and possibly Faraday horns, a red light on the wall in the assembly gym, and a gentex commander (Maybe version 1?) in the PE gym/Lunchroom, and finally an old Simplex horn in the choir room. The annex just has Simplex horn/strobes. The portables mostly have Spectralert advance horn/strobes, but the public speaking portable has a Spectralert classic. Also for emergency lighting, some lights in the front of the school and the annex have what looks like little red “O”s in them so I am guessing those lights stay on, the rest of the school just has Dual-lite twin heads and the “LBC lighting” I think it’s called. The portables have an old dual-lite and the public speaking portable has both the old dual-lite and a newer led one. However the science one has one on the side of the room and the one next to the door has no heads but somehow has a working battery.
Oh yeah the problem at 14:10 is supposedly very common with bg 12's and its dangerous since if someone pulled it it wouldn't set of the fire alarm. Of course for newer buildings smoke detectors will trip but for older buildings it's more of a hazard
This school is in Canada we only have voice evacuation/mass notification systems in hospitals and high-rise buildings over a certain age size or the amount of occupants in the building does not affect if it's required or not
I’ve been thinking about the horns seeming out of sync. Assuming the alarms actually are in sync, it is possible that it’s the speed of sound that is causing them to sound that way. Given the speed of sound is approximately 343 m/s, and the somewhat open concept of the school, we might just be hearing the delay it takes for sound to travel
That’s what the fa technicians are saying but even in the gym where you only have two in the same room they still sound like they’re going off at different times
@@HenBasketFireAlarms yea it’s not good but not sure what you could do about it everyone says sync modules but that does the same thing as the sync in the panel
Nice job I like to use walk test with horns and use smoke but you have to have a can of air to clear it or may go off again also it hard to find the spot place the magnet on smoke detector sometimes I also noticed detectors were not marked with there address on them wich is helpful in identifying with detector tripped as well for trouble shooting from Rich Owner of an Alarm Company.
14:26 That pull Station has got an issue! I remember last years testing video there was an issue with another pull station in that school, is that the exact same pull station?
No it’s a different one usually every year there’s one or two somewhere in the school district that act up just depends if you don’t pull it certain way
@@nics-systems-electric Huh… that’s weird, I have no idea why they do that. I have a Notifier NBG-12L and a FireLite BG-12L, and I don’t see why they would do that!
Their intended purpose is only for make up air as only specific doors open not all egress routes as well they only open on smoke alarm not pull station or sprinkler flow
I'll be shocked if you reply on a video this old, but what is the lighting system your school uses? The models of the switches would be appreciated, but I could work with a brand name. I like the design and the "networked" aspect of it.
Is the footage of the exhaust fan going in both directions as it slows down after it gets shut off due to the camera or the fan itself? It looks like it spins clockwise for a few seconds, then counterclockwise for a few seconds at first, and then stays clockwise at the final stage when it finally stops.
Definitely cameras that's extremely normal for cameras to do you've noticed they do that with almost any spinning thing happens when it is going through different speed ranges and when it matches the frame rate gliding in and out of matching it
If it was a accessible room that was likely to be occupied and in public reach then it probably would however the only people that should and will be going in there should also have the knowledge to realize what can happen I do agree it would seem good to have some protection on the front of it however that may reduce airflow
@@nics-systems-electric so is the electrical shed and the main building panel connected via the local building network? (And if it is hopefully it is vlanned off from the rest of the network)
1:56 I wish this was a joke for April Fools, but I really want to know the full name of the school. I have been anxious to get your location for years.
I know that you are keeping your location private, but I wished that I could get your location on April Fools. I am already sure that getting your location is NOT going to happen. 😂😂😂
Actually I’m surprised that they are not using beam detectors for the atrium and gyms having remote key switch testing/reset capabilities. I’ve installed quite a few over the years in applications like this. It saves on the amount of smoke heads needed to cover an area/ no need for lift for testing/ and less damage from sports stuff. Basically a laser beam goes from one side to a reflector and bounces back. The unit can tell if there is smoke based on the beam pattern of light coming back. Some brands and models had a receiver on the opposite side that had to be wired in. I liked the version where all wiring and test switch was on one end. For true testing you could put a can of smoke on the end of a stick in the middle of the room or brake the beam with different levels of colored film representing different particles in the air.
@@BR-ft2xg yeah that's my thoughts too that they should've install the beam detector however I have seen a lot more problems with beam detectors causing false alarms and troubles so maybe they figured there would be an issue there
There are strobes The system is apparently synchronized we didn’t think it was but what we have been told is it is just the echo but system sensor synchronization is enabled and there is no reason for it to not be working but it still doesn’t sound like it is to me either
@@sieandknsproductions3491 the panel in the mechanical room second floor of the wood shop where the addition meets the original section it's not shown in this video but is in other ones
Seems like several of those pull stations didn't work how you'd expect. Seemed activated but requires you messing with it to trip. Seems like that shouldn't be possible
Even so, I could just imagine someone else trying to pull the fire alarm in a situation and then no one knows about it because you already tried to pull the fire alarm. Maybe it's just a design flaw everyone overlooked?
@@Reeseshead I would say it’s probably a slight flaw maybe if you don’t push it in hard enough it won’t activate not sure what I did differently with that one I’ve had it happened before
No that's in the movies and very old pull stations that you can put glass in however usually it's just glass I've never ever worked on one that actually has anything in the glass
Because it makes it more difficult for the person that’s following you around trying to figure out whereabouts in the buildings you are it’s just as fast if the person that’s writing everything down just hits acknowledge every time
@@nics-systems-electric ok I get it now! It does make sense and after you guys complete the pulls stations and smoke detectors you guy put it to normal and then set off the entire system!
I prefer the walk test with horns if by myself then I can see and here test but can always check history which detectors tripped I noticed detectors were not marked with the Detectors address (detector ID) From Rich Private alarm contractor nice job well done note it's hard to find right spot to place magnet on smokes Sometimes good check with test smoke can bring you can of air to clear smoke otherwise it make take while to smoke to clear out of it may go of again until it clears
I talk about it in the video that the one in the E-house is for the portables which there was once 10 and there was none at the time of this video but 2 to 4 will be coming back this summer

When the fan started up it SCARD Me
Nic: "Hey jamie we should have one on this side of the rooftop, eh?"
Jamie, somewhere behind the camera: *euraugh* 👹🗣
Oh yeah the problem at 14:10 is supposedly very common with bg 12's and its dangerous since if someone pulled it it wouldn't set of the fire alarm. Of course for newer buildings smoke detectors will trip but for older buildings it's more of a hazard
At least moving the handle a bit when it's pulled down does activate it.
This also happens with Simplex T-Bar pull stations.
Fan sounds really cool when it turns on
nice video keep up the work love the vids the fan starting up scered me just like the last video when I knew it was going to start lol
Thanks ya they pretty loud
A large school like this should really have a speaker system w/ voice, not a horn system. Horns should only be used in small systems.
This school is in Canada we only have voice evacuation/mass notification systems in hospitals and high-rise buildings over a certain age size or the amount of occupants in the building does not affect if it's required or not
Love the fan startup
Scared the crap out of me tho
Those fans sound so good when they startup
Agreed.
It made me jump when they first started up.
I’ve been thinking about the horns seeming out of sync. Assuming the alarms actually are in sync, it is possible that it’s the speed of sound that is causing them to sound that way.

Sounds to me like they just forgot to turn on sync, or the NACs aren’t synced with each other
@@HenBasketFireAlarms apparently system sensor sync is enabled on all nacs and booster panel so they say it should be fine
@@nics-systems-electric really weird that they’re out of sync then
@@HenBasketFireAlarms yea it’s not good but not sure what you could do about it everyone says sync modules but that does the same thing as the sync in the panel
Awesome video!
I knew it the switch inside the pull station didn’t go off.
been waiting for this!
I enjoy watching your videos nic! I should be getting a rare fire alarm. We’ll two of them.
Cool school I like the fire alarms
I wish my high school looked like that lol. That school is really nice
It do be nice
Nice job I like to use walk test with horns and use smoke but you have to have a can of air to clear it or may go off again also it hard to find the spot place the magnet on smoke detector sometimes

4:18 THAT FREAKING SCARED ME!
finally!! That campus looks so modern for 2015 standards, but very nice!! cant wait to see more
My school added a new science wing in 2016, its the only nice part of the school.
@@dabitzz nice.
2015 isn’t that long ago
@@nics-systems-electric 2015 was 7 years ago, so I still kinda find It surprising
@@alexgilbert2 7 years is like brand new
im terrified of fans but those were cool
How often do the fire alarms get tested at your high school
Full system test is once a year and then the system is supposed to be activated once a month
This school is like a mall
Love seeing those big fans operate! Are those fan motors controlled by some sort of VFD? And are they fed by a 600V three phase or another voltage?
No VFD I don’t believe at least if there is one it’s only for a soft start or softer at least but 600/347 v three phase
14:26 That pull Station has got an issue! I remember last years testing video there was an issue with another pull station in that school, is that the exact same pull station?

Thanks
Nice!
2:27 Do the doors also provide the first evacuation routes when they open?
Their intended purpose is only for make up air as only specific doors open not all egress routes as well they only open on smoke alarm not pull station or sprinkler flow
That is one fancy system dude I am helping to put one in at a strip mall in our local area
I always thought that was just a 3030 display on the panel, but I never noticed the controls enabled led on the interface.
Just a 640 with a NCA-2
I thought the video was gonna be longer like 2 hours. But still great long video
damn all the schools there are big i wish my school was like that
We have some really small ones too
The fans could be aerovent
(Not sure about the concealed fan in the soffit)
I'll be shocked if you reply on a video this old, but what is the lighting system your school uses? The models of the switches would be appreciated, but I could work with a brand name. I like the design and the "networked" aspect of it.

I wonder why there is no protection on the fan inlet, you can just stick your arm inside?
If it was a accessible room that was likely to be occupied and in public reach then it probably would however the only people that should and will be going in there should also have the knowledge to realize what can happen I do agree it would seem good to have some protection on the front of it however that may reduce airflow
What job do you do that you get to test fire alarms and veiw them (basicly work on them)
I’m just working with my school district electricians I was doing it at one point as work experience for school
true bro i am so excited😊😊
Is that panel in the old portable electrical room networked to the main panel? And is the field house on that panel?
Yes it’s networked and the field house is just off the main school panel slc and nac nothing to do with the electric house panel

I Would Not Use Ladder Lifts That's A Big No For Me Whoa I'm Really Scared Of Heights
They should have installed scorpion smoke testers 62ft in the air
Would be interesting I've never actually seen them on a system

How come they didn't sync this system? Also, no strobes?
There are strobes The system is apparently synchronized we didn’t think it was but what we have been told is it is just the echo but system sensor synchronization is enabled and there is no reason for it to not be working but it still doesn’t sound like it is to me either
24:26 is the fire alarm system connected to the suppression system?
Yes
It's gonna suck when a fire drill happens and it's winter cause all that cold air is going to be inside
Either the fans are probably connected to the smoke detectors or they have the fans turned off in the winter
You said your high school do you currently go there are you an alumnus? Thanks for the video.
1:08:15 When they silenced the alarms, I heard one out of sync still going for a second. Is that an outside horn/strobe?
No that was just one in the addition off the booster panel just takes a bit longer to silence

Why is there a hood outside the exhaust fan room beside the door?
It's on the other side of the non-smoke fans i'm not sure the purpose of those fans or when they come on

Nah it’s pretty easy to navigate probably a lot easier in real life than it looks on camera
