I somewhat find the concealed sprinklers and the KFR sprinklers, or ones designed similar, very interesting. My school does use concealed, pendant, and sidewall sprinklers. The sidewall ones are usually outside, with a metal cover on them. The pendant ones are usually inside the classrooms and other buildings on the premises. However, not all buildings have them. The concealed ones are usually in front, outside the toilets. Pretty interesting to have them at a school, at least from where I am. Anyway, thanks for the info!

thanks, now I know what those things are in my school and restaurants! I thought it was some sort of fire sprinklers

Very cool Love your channel!

The liquid doesn't expand, the air bubble inside, which is precisely measured expands as air does when exposed to heat, bursts the glass due to a pressure increase. The air bubble is engineered to burst at different temps based on the application. True statement.

Thank you very much dear…. As it is very useful for this time🎉😊

Nice bro bro.

Awesome video I always enjoy these ones it was cool to see a low flow residential one like the ones I use I don't know if you did it because I said I wanted to see it or if you just happen to do it either way I'm happy I got to see it

Concealed sprinklers be like, *pop* “Yo” *pffffff*

We have a Concealed Fire Sprinkles at my School.

Is it possible for Steam to trigger a sprinkler head? I ask because one time steam from my tea kettle triggered my smoke detector.

Can you connect the fire alarm system to it so it’s more official

Is it true that a skittle can tigger a sprinkler cause that’s what happened at the local middle school supposedly

Drink every time he says “sprinkler head.”
