The generator might have been trying to start, but couldn’t under the load of all the ac units so it may have shut itself off to prevent damage to appliances OR the generators collector rings. Could be.
Generators are extremely expensive so the building likely had one generator bought when the building was first built and that was it. Likely cannot cope with modern electrical demands and if people were all running A/C at once. Backup generators draw a lot of amperage power on kick-on so if it was purposely trying to kick on repeatedly it would have been frying the wire insulation which is what the burning plastic smell was. Fire alarms operate on a low voltage circuit and smaller grade wiring so those would have been the first to burn up.
Not really a power outage, but rather a brownout or power sag. This happens when you lose a leg of a 3 phase system, lose a neutral, or if already in a power outage a generator not supplying adequate voltage. In which case incandescents will work, but only dimly, and the AC panels will light up but be virtually useless. Flourescents and large LEDs will not light because they both require 120v coming in, and any heavy duty motor (compressors, heaters, large 3 phase ventilation fans) wont work at all. Small fans may work, but if they do it'd be only at a very low speed, and you're right about the fire alarms they will sound with low voltage, normal voltage, and no voltage due to backup power supply but they cant cope with fluctuating voltage.
0:00 power went crazy and out 2:30 some have some not (also not good for this) and 2:32 fire alarms went off because there’s a fire when there’s a power outage in the building.
Cause voltage could barely power the alarms. It was trying to go off but because of the low power it kept repowering up and down. So they couldnt do the correct Horn/Strobe
The thing with the fire alarm loosing power and acting weird towards the end of the video is definitely a sign that the backup battery from the system's panel is not doing the job of effectively with providing backup power for the alarm system which seems unsafe for if an actual fire ever happens during a power outage.
Actually it has to do with the fluctuating voltages. The battery backup for the systems panel is meant only to provide power in low or no voltage situations. It is not a clean power source (clean power meaning it can suppress voltage sags and spikes) that makes it completely useless in a situation like this where the generator isn't supplying consistent voltage. The backup battery simply can't cope with fluctuating voltages therefore the dirty (fluctuating) AC power will make them malfunction.
The fire alarm likely went off from the burning plastic smell, which seems to have an old backup battery. The horns were obviously severely underpowered near the end. The minimum rating for a fire alarm system backup battery is 24 hours in standby followed by 5 minutes in alarm. I’m betting the backup battery has long passed it’s 4 year lifespan too.
AC alarms will sometimes chirp when transitioning to battery because often the battery voltage will drop when the battery suddenly gets loaded by the detector circuitry
The fire alarm panel has backup batteries that *should* be able to supply full power to the entire fire alarm system for 24 hours if total power is loss. Here it sounds like the panels batteries were dying or the NAC (basically a battery cabinet for the alarms on say each floor) on your floor was dying.
The NAC is not a battery cabinet. You're referring to a NAC extender. The NAC, Notification Appliance Circuit, is a circuit that is a part of the main control panel. It's what the alarms plug into. A NAC extender is a battery cabinet that is located on each floor to supply power to alarms that the panel does have the capability to power.
When the fire alarms went off reminded me of my power outage story It happened a month ago. We were learning about geometry. Well, the power goes out. We thought it would last for 39 second IT LASTED FOR AN HPUR! Then like 5 minutes into it, our clocks our battery backup. Well the backup failed and so did our WiFi. Then at lunch I heard the panel beeping to the fire alarm (it didn’t go off though)
Something broke and it just started to smell. edit: because remember when the fire alarm went off? Well there is a fire, but the power is out so it broken. And the smell? Well that’s plastic burning.
When the generator was running and the utility power was out, you probably only had 110v coming into the stuff in the building. I wonder what was powering the elevator buttons and the indicators though.
At my house on the 6th our power went out and our smoke alarms chirped and I'm afraid and triggered of loud noises and power outages at the same time and storms I also feel like my family isn't supporting me instead I feel like I'm being made fun of and it depresses me. The smoke alarms only chirp twice and then once when power goes back on
Was the fire alarm going off during a power outage that is just crazy I may have been in the first line but not in the fire alarm going off during the power outage
My guess it that a wire got red hot and the insulation melted and made that smell or that the generator started smoking I don't know tho because I don't live ther
Some appliances have capacitors for the low voltage DC control panels, so the panels can work for some time after a power outage but relays have no AC power to switch, so in this case the air conditioner doesn’t actually do anything.

Fire alarm systems run off of the building electricity under normal conditions, in the case of a power outage, the control panel will run off of batteries in the panel.
Gary Beltz Oh that, I think that's just when the battery on the panel got low, and the system was still activated, and the panel couldn't power all of the notification devices
Here's my theory, not saying your wrong, i was not there so i'm just gonna guess. Are you sure the power outage wasn't cause due to a issue in the maintenance room? Could something have tripped causing the power to go out, but then the generator kicked in and made problems worse?
2:31 a power outage should not activate the fire alarm. Unless their was a fault or trouble that somehow messed with the system. They also could have been seeing if the batteries where on. :edit its been 5 months and I just read the desc
My geuss is when the generator tried to start there was so much load that it quit trying to start and got really hot and either smoked or caught fire briefly causing the smell thus stting the fire alarm system off. When it comes to the fire alarms i think the batteries in the fire alarm control panel in the matinence room were either weak or bad thus causing the horns to act and sound weird.

The elevator had a system where when the power is out it goes out of service and hose to the first floor.

@@chronically.advocating Oh ok
@@chronically.advocating BS, the battery directly supplies the fire alarm panel and should be good for 24 hour power cut and then sounding for 2 hours
The building lost one of the power phases. This happened at my old job years ago.
bro there is single phase and 3 phase 3 phase is for big motors
The fire alarm likely went off from the burning plastic smell, which seems to have an old backup battery. The horns were obviously severely underpowered near the end.

Smell doesn't set it off?? I mean, there's no way to detect a smell. How many people believe this? I've encountered like 20 people that believe this.
The alarms appear to be being powered with AC power, which causes them to chirp like that.
AC alarms will sometimes chirp when transitioning to battery because often the battery voltage will drop when the battery suddenly gets loaded by the detector circuitry
5:05 Big issue, Low battery in fire alarm control panel is a Safety hazerd
You mean hazard
The Spectralert's parents were probably siblings. Enough said.
It’s strange it’s like sections of the building are still getting power but not enough power to run things properly
Just like a brownout; we still HAVE power but due to a drop in voltage; lights dim and some electrical equipment doesn’t work good
When the fire alarms were going off at the begining... those power outage lights were blinking on and off. I laughed at that! 😂
There aren't any *power outage lights*...

+msj191961 Stop acting like you know everything
The batteries in that system were definitely dying. Likely due to not being serviced/replaced every few years.
The alarms tried to start, but the panel has backup battery’s. They probably died...
You mean Batteries
There might of been a HV ( high voltage ) problem so only LV ( Low voltage) in the building. So only stuff that works low voltage will work.

You'll rarely see fire alarms connected to the electricity. They mostly run on a panel battery.
Fire alarm systems run off of the building electricity under normal conditions, in the case of a power outage, the control panel will run off of batteries in the panel.
