Anyone else here do fire safety? The alarm panels are very cool to use. I get to see behind the scenes of all kinds of places.

>>67614 What is your job title specifically? Fire Safety inspector? How much are average salaries? This looks like a very fun job.

>>67614 I do, but the places I go are usually 1960s tech, most of the people working on it are old as fuarrrk. Also asbestos.

>>67659 "Junior fire safety technician" its only been a month, I'm still lost without a lead tech saying what to do. Starting pay is low 20s (CAD not USD still pretty good). Doing the easy stuff right now like sprinkler flow and tamper switches. Acknowledging panel alarms and resetting it while someone else tests devices in the building, that sort of stuff. So much to learn. Attached picture is the inside of a NAC booster which the suite buzzers are controlled by. 4 loops, 4 floors. We were pulling the wires so the devices would appear in trouble and the lead tech could write them down from the panel. Figuring out how the new building was wired.

Obviously im not sayin wanna do what you do but what qualifications did you have to take out of curiositiy? Also, do you have any other pics, thar lookz cool.

ayy I remember seeing these kinds of panels at my school and wanting to know how it all worked. Cool soykaf. No idea what I'm looking at but the pretty colors makes up for it. Nice posts OP

>>67709 I took a basic pre electrical course going over how components like capacitors and transistors work. Real nitty gritty like how to calculate dialectric strength, electromotive force, and more simple stuff like ohm's law. Haven't needed any of it so far, and forgotten most calculations, but pretty cool stuff too (for example: AC is a sine wave because the motor starts at 0V, spins 90° to +120V, spins 90° to 0V, spins 90° to -120V, spins 90° to 0V again, over and over). I put the completed course on my resume, signed up for a fire extinguisher inspection course, and applied to a fire safety company. Went for interview, got the job and gave my 2 weeks to the warehouse. I go for the fire extinguisher inspection course next weekend. Picture is some sprinklers I was shown how to use today. Way older tech than the computer panels of course but somehow harder to understand. I have a lot more research to do on them. Each big red bulge is a one way valve like a diode for different areas and floors of the building. They are held shut with air pressure and when the pressure drops low enough it opens, letting water through. Spronklerheads have a glass piece inside that shatters from heat, the air leaks out, trips the valve, this is how the sprinkler system "knows" where the fire is. When the water flows it trips an electronic microswitch and appears on the fire alarm panel. Those switches are inside the plastic red boxes behind the gauges. One gauge is air pressure, the other is water pressure. These valves need to be opened and reset by hand, the rusty water inside smells gross.

>>67675 >going inside buildings is toxic okay schizo

>>67737 There's actually hydraulically actuated valves in some systems that work on water pressure alone instead of electricity. As long as you have water pressure you can use the system to control remote valve opening and closing. >>67751 >Having to crawl through toxic substances and some antiquated firefighting agents is schizo Pic related is a halon bank, pretty interesting gas system, activating a tank usually triggers pneumatic solenoids, horns, and time delays to allow for escape before the air turns into toxic gas

>>67764 Thats cool I haven't seen a halon system yet. I am pretty sure all the sprinkler systems I've seen just use air and water, the electric switches are only for alarms and stuff. Here's the most soykaf tamper i've seen so far, at the bottom of a townhouse parkade entrance stairwell, up a stepladder through a hatch.

>>67614 I work a s private security, mostly in industrial places so I have to check the fire safety (not on a technician level but I need to know how to use the hardware). In general fire safety is the most interesting part of my job. I have a dedicated computer that runs a software to monitor all the fire safety of the site I work (cannot post a picture for obvious reasons). >>67764 sexy pic I have the same kind of installation for server and electrical rooms, the tanks are green and contain some gas (not halon can't, recall which one tho). I have a nice water sprinkler installation there to, I will try to post a photo of the big motor next night :) I heard it one time as a sprinkler head as broken (due to a faulty installation) and damn that was huge.

>>67737 Your numbers about ac motor voltage are incorrect, 120V is the effective voltage, the peaks are sqrt(2) times that, so 170V and -170V.

>>67768 Also many motors are three-phase because that's more efficient.

>>67767 >I showed you a halon, plz send SCADA noods Halon is being phased out because it is toxic, I've seen CO2 and other inert gasses, but another popular one is FM-200. I always thought it is ironic that some gases turn super corrosive when or toxic when they come in contact with high temperatures and flames, since they are being used as fire suppression.

>>67794 Definitvely some CO2 system yes and some FM-200 for server rooms. Here is the red bad boy.

>>67768 Whoops that's embarrassing. Think I was tired when I posted that. >>67800 What a beast! Don't think I've seen one that big yet. Here's a cool one I saw a few weeks ago, Ford V8. And here's the weirdest panel I've seen so far, felt like a glorified burglar alarm.

>>68107 the more you look at the panel, the better it gets

Fire safety is so cool, if you can tolerate the folks you have to deal with. It's probably too late for me (programmer) but seriously >required by law, demand will never go away >regulated and therefore barrier to entry for illegals >can't be easily automated >doesn't particularly fuarrrk up your body, nor particularly dangerous >interesting technology >go into various buildings >improve safety

>>68112 The >Troubl< is because of the two wires outside of their screw terminals above the screen. >>68113 All the reasons I love it right there. I have no problem with immigrants but it is like kicking dead whales down the beach to work for a company that churns through them for cheap untrained labour, like my last job. None of that here. And its not too late for you dude, go for it. The lead tech I worked with today started at age 40 in 2008. Still going strong cause like you said, it doesnt fuarrrk you up. And this isnt related to the thread, just a cool song that feels lainchan-y to me. https://www.youtube.com/watch?v=9h1NpQiz02Q

>>68113 mandatory fire alarms in the house are the soyest wiggoid shyt. for shared buildings idc cus only retards actuially spend any significant amount of time in those

>>68390 You sound like someone who would blankly stare when I inspect their gas appliance suite, and all 3 smoke alarms are deficient ions due in 2012.
