- I'm explaining how fire alarm systems work for new technicians or other employees who deal with these systems. This is my 16th video in a string of many Khan Academy-styled lessons. This video introduces sprinkler systems and describes how they're monitored by fire alarm systems.
I WILL ABOSOLUTLY NAME YOU THE GRAND FATHER OF FIRE ALARM SYSTEM WOOOOOOW I NEED TO GET YOU A GIFT MAN
dude these videos are absolutely amazing! I've already watched 16 straight in one sitting. Thanks for all this information, really helps understand the shit my journeymen don't have the time to explain on site
You must have a little time, considering you watched 16 in one sitting 🤣
I remember watching your videos a couple years ago and was reminded of them this weekend. They were a help then and now, too, and I definitely recommend for others
getting into the work!
Joe, thanks for these videos, 11 years later. You should consider uploading them to Udemy or another platform like that to get a little income coming in from it.
Need a video on elevator recall! These videos are great.
@Joe Klochan This YT "course" has been very educational, it's made me think of alarms in a different way. But what I don't get about sprinklers is that, what if there's an electrical fire? It's not like the heat would be less intense. Also, like trouble bells, I've noticed many buildings have waterflow bells by the panel and/or outdoors. I guess this tells people it's a real fire, because sprinklers do not activate during prank alarms or fire drills. But does the panel need to be addressable to make such a bell ring?
Sprinkler systems are not considered life safety devices for that reason. They are for property protection. In the case of electrical fires, smoke detectors would be needed to detect them. Trouble bells are different than sprinkler bells. Typically, sprinkler bells are not tied to the fire alarm panel at all. There are usually two independent sets of contacts on a waterflow switch. The sprinkler bells run on 120 VAC, and the hot leg of that circuit goes through the waterflow switch just like a light switch. When water flows, the contacts close and 120 VAC is passed to the bell, making it ring.
Thank you so much. I learned something new today
where can i learn, in a class room setting, how to install and wire in fire protection systems? thanks for the video
Believe it or not, I use Microsoft Paint. I believe he uses a program called Smoothdraw. I tried smooth draw as well. It works better with the pen/tablet I use, but I can't copy and paste images as easily, and that's a big part of what I do. I use screen capture software called "Snagit". It's only $50.
Happy to be in same city with you!
Where are videos 14 and 15? Thanks for all the info. Ive been in the bizz for quite a few years and this info is good!
great work...thank u very much
Every time I run washing machine, the pressure in the fire sprinkler gauge increases. We thought the gauge might be faulty so we replaced but still the same. the pressure increases with every laundry. Based on your diagram, i don’t understand how is this possible?
Yeah that doesn't really make sense to me either, but I'm not a sprinkler expert.
I was wondering, what illustration software do you and Khan use to do these videos?
Average bulb temp is 155Deg. Just fyi
is shut off valve also called zone control valve?
joe!!!Where are videos 14 and 15?
so u just dont know what kinda element/liquid is used to fill those switches?!!..then what u are trying to make us understand in this 10min video??
