I suppose that the LED screens ought to either enter emergency mode, start displaying pre-programmed evacuation guidelines or just perform an emergency stop under the control of FACP. All the decorative stage lighting (beam lights, LED par cans) should also be tripped.
LED walls are designed to be completely external with any system. For example, the computer that’s running the content to the wall usually has the Wi-Fi and Bluetooth turned off. It is a completely off the grid when it comes to video.
@@greggjoseph2931you can wire in a separate two-wire trip contact that activates the preprogrammed emergency functions without it being connected to the network.
@@greggjoseph2931 He means that it should be programmed so that when the fire alarm does activate, the FACP opens a contact relay and turns the screen off or preprogrammed message. In some areas, its actually code for that.
The alarm is a warning and does not require a full evacuation until the area is investigated by firefighters or a certain threshold of smoke/heat detectors go off. If it does then they will sound the evacuation tone.
Pov: your at school causally doing work, chatting with best friends, all of a sudden you hear a lockdown drill sound but it was suppost to be fire alarm:
yall im sorry this was the dumbest thing i have said on youtube Basically.. The “lockdown drill” sound plays so every teacher closes there door blocks it. But then, they think why is the fire alarm the same sound, then they realize its a fire drill so they go outside, hoped that help
If the fire alarm goes off during a lockdown, you are instructed to shelter in place unless you see signs of fire or smoke, or are told otherwise by the proper authorities.
How this works: a sprinkler system is always pressurized slightly, either with water directly (wet sprinklers), or with air (dry sprinklers). A pressure gauge on the system keeps an eye on the pressure level, and if it drops suddenly, triggers an alarm the same way pulling a pull station does. The logic here is that since it’s pressurized, the only way the pressure will drop is if a sprinkler head starts to discharge - nominally, due to a fire. Of course, if a pipe breaks, the same thing will happen - the pressure gauge has no way to tell, after all.
Depends of where you are when watching the video. In my country for exemple the fire alarms don't sound at all like that and there are also none to be found in private homes, with the exception of the battery powered smoke detectors that also don't sound like the fire alarms in public buildings.
I kinda wanted to see some random woman start screaming that then sets off a chain reaction of screams, panic, and horror. Kids and old ladies getting trampled and men falling down the aisles from the highest point 🤭😂🤣 Also, it was me...I pulled the alarm 😈
Crowd crushes are actually really horrifying, not uncommon, and extremely deadly. There have been many instances of fires starting, people panicking, rushing exits that are poorly maintained or partly blocked, and then dying not because of the fire but because the pressure of the panicked crowd kept them from breathing. It’s a horrible way to go, and a big reason modern fire codes require doors be equipped with push bars (aka panic bars) instead of knobs or levers, and open outwards.
That’s a myth. With sprinkler systems, each individual sprinkler is heat activated: only the ones above or by the fire go off. Not as dramatic (which is why Hollywood does it differently!), but lowers the damage.
POV your chilling in class on a snowy day and you hear this at that point you were contemplating whether you were gonna make it there the snow on a fire drill or not
I think this stadium should have smart enhanced synchronized due to some people have disabilities of epilepsy. Or most people of it depends. Such as wheelock or gentex for example I don’t know why they went for system sensor but system sensor can be synchronize-able too. so why not gentex and system sensor at the same time?
System: Simplex system. The code 4 beeps sound custom. Message is custom. Main PA was overrided by FACP. Ive been here they have Simplex truealert speaker strobes. Main stadium PA locked down automatically once activated. All custom audio. Low beep in beginning might have been a transmission tone
Not simplex!!! it’s Firecom. The 1000hz tone is def not simplex! same message as some 4100u/ES panels probably due to the company using a similar speech synthesizer. Firecom is very common in stadiums, in fact it’s the system at the staples center. The speakers must be tapped at high wattage as it’s Deafening!
They’re not supposed to. In a big space like this you do NOT want everyone running to the exits at once: it would cause a crush, and is a huge disruption regardless. Rather, you send a “standby” alert (as the system does here) and wait for a little bit. If additional sensors trigger, or if an all-clear isn’t sent by the building staff, the system will start sending evacuation notices in a phased sequence designed to get people closest to the danger out the fastest, and in a way that avoids a crush. Modern buildings are designed such that fires can’t spread quickly - they have to burn through barriers designed to withstand fire for various periods of time (from a few minutes to hours, depending), ensuring you can take time to get everyone out safely, assuming they need to at all.
@@kilodeltaeight And the buildings have sprinkler systems, so in the event of a real fire, the sprinklers would stop the fire from spreading, if not completely extinguish it.

They probably just silenced the alarm and kept going. Generally in a facility like this, they do not evacuate unless it is actually necessary.
