I know in this video I said I was happy with the flow rate and coverage however I've decided I need more so I will be making more videos in the future of getting more flow out of the system I have done the work already the videos will be coming out in the next couple months
Hi from Sydney, Australia. I worked in the fire research area of Aus Govt primary research organisation. A bit of trivia - Australia has the oldest sprinkler systems in the world, and no deaths in a sprinklered building. Cheers!
Only fun thing that would make the demo better. Start a little fire underneath in your fir pit we see on the patio and see how well it puts a real fire out. (do not repeat the entire test, just rig it up again the same way and turn on the water to the tripped head and see how well it deals with a real fire.
this was so freaky. As you was testing the Fire Alarm's our adjacent Apartment complex's central emergency fire alarm system which triggers EMS Dispatch sounded and there was legitimately a fire inside an apartment.
Yeah they're pretty chill it's not a good neighbourhood to move into if you are bothered by noise as there is the elementary school right behind the house on that can be a crazy place at night
@@nics-systems-electric yeah, i figured as much, i can handle kids :P my daughter runs me rampant wild sometimes with her friends, but we do have a understanding, when i say lower the volume, she makes SURE to get it down. but yeah, the cardboard security alarm incident, the fire alarms.... personally, id be like, ahhh nic over there setting shit off again LOL!! I was honestly being sarcastic about that, i wouldnt bother me at all.
@@CapStar362 yeah I am a little noisy but my noise gets overshadowed by the school with the nighttime activities the most popular is jumping up on the wall and ripping the sprinkler heads off the outside setting the fire alarms off and the fire department rushing down at all hours of the night and lighting stuff on fire on the side of the building is another common one fireworks overdoses and just general people being idiots etc.
The only way to add a pump to increase the GPM is to add a buffer tank. You need 110 gallons reserve per head to cover 11 GPM. That’s @ 10 minutes. If the requirement is 20 minutes you need to double the reserve capacity.
I am going to start by changing the really restrictive barbed Pex fittings that restrict it down to like a quarter inch first and see if I can increase my flow that way if that isn't enough then I will have to do buffer tank for sure
for years i have wanted to set up a fire alarm system i constantly brows ebay for used systems and alarms itrs all quite expensive for somone on a fixed income so i just have to live with watching thease videops insted wich i still enjoy.. would love to have a base building game were you can build a fire alarm and sprinkler and electrical system im very tehcnical minded and like to mess with that sorta thing wich is why in games such as 7 days 2 die i make complicated electrical networks through the entire base
You don't have to buy brand new sprinkler, you just need that rod in it and it's easily to replace you., just have to turn off the water and then put that metal piece up and put the rod in.
I don't think that's how it works. The glass rod breaks and it is put into the sprinkler during manufacturing. You'd have to buy a new rod anyway and I don't think they sell the glass rod separately but if you have done this before, I am wrong.
If it was only for demonstration sure you can put some thing in but the sprinkler won't activate at its design temperature anymore and would be pointless you can't unscrew the retaining set screw in the sprinkler it is filled with a resin the way that I have done it just for demonstration is to put a small bolt and nut in place and tighten it where you can pull it out not a perfect seal though only good enough for a couple minutes until you pull it out
@@oaklynnmielcarek Here in France they actually sell similar rods as a spare for smoke vents. These are basically roof windows or skylights that are opened by pneumatic cylinders and CO2 cartridges. Manual stations allow to open the smoke vents by pulling a handle that will puncture the cartridge, however there are also automatic devices that have a glass vial (or "rod") like sprinkler heads, except their failure will not release water but a spring-loaded pin that will puncture another CO2 cartridge in order for the smoke vents to open on their own as well. These vials also come in various colors, one for each temperature, just like sprinkler heads. They are really meant to be replaced individually as well as the CO2 cartridge since the actuating device itself is reusable. Not sure if these vials would fit on sprinkler heads though.
I was a Firefighter for 23 years. Stopping the water coming out of a sprinkler head sucks. But if the sprinkler head gets knocked off accidentally, you have to stop the water to prevent property loss.
Garden hoses use GHT (Garden Hose Thread) whereas pipes use tapered threading (NPT in USA/Canada and ???, BSP elsewhere). Usually when I need flexible hose to attach to piping, I'll use barb adapters and hose clamps. These are usually carried in most hardware stores. You just have to make sure what you use is meant for piping, and not garden/lawn. One scenario where GHT is used, is typically hot water storage tank drain valve. I have not added sprinkler system to my home, though I contemplating it. I have an unusual situation, where there are 3 booster pumps the size of a large cargo van each that were recently added at the end of my block (in a faux house)... and I found out from my local water council that my home's feed is tied into a 200mm (8 inch) main, just 30 meters (100ft) from my house. I had to use 2 PR valves to reduce my pressure to normal domestic levels... Due to burst flex pipes in dishwasher after water council added these pumps/booster station. I hooked up a 100PSI gauge and it pegged. 200PSI gauge... it pegged it... Finally I added a large 2000kPa fire sprinkler gauge and it nearly pegged it. Gauge only has kPa markings, but doing conversion, this was near 300PSI! Come to find out after council did an evaluation around the block, that someone had connected my main where it wasn't supposed to be, and council moved it to a 100mm/4 inch feed. However, pressure still is over 1700kPa(250PSI). Bad for house, but tempted to test and see how it performs with sprinklers tehehe! I remember watching the pump station being built, and somewhere still have photos of the in and out supply piping to that place. The pipes were almost 1 metre in diameter. Absolutely huge
Yeah, I learned that after the fact I should've known better. I do need to find some sort of adaptor for sure. and that definitely does sound like an interesting situation at your home!
@NIC’S - SYSTEMS & ELECTRIC On a well, right in the well room, I see around 75 or so after it replenishes the pressure after a shower or something. 250 would have explosive results on a shower or at a sink faucet, let alone a fire sprinker.
@@glonkfpv Had, yes. unfortunately... I came home to a flooded kitchen and laundry room because the hose for the dishwasher burst, and the valve in the washing machine (modern plastic crap) also burst. That's when I went through the gauges, upping in size until I did not peg them anymore and was blown away by what I was seeing... I also had wierd pulsations in the pipes. I can only surmise this is due to however the council runs the pumps (the system that controls the demand of them and operating parameters). I do not know what they run, but it seems as either there is an out of balance issue between the three pumps, there is harmonic resonance/feedback loop in supply piping, or something else. The pulsations stopped after council changed me to a smaller mains tap. Craziest thing I ever seen. All the piping in my house is copper and soldered. No PEX, push fits/sharkbites or any of that kind of stuff.
You said you might need to buy new heads... Over here in the UK you can buy replacement triggers and parts, keeping the main casting in place - surely cheaper? Do you not have that in Canada? (Obviously if activated due to a real fire you wouldn't recycle, that's a given lol)
Some of them I think you are able to replace the bulbs however not these ones they have a resin filling where the set screw is I'm not sure if it would be legal to replace your own glass as that may be altering the device I have a feeling CSA would not allow that and you would need to replace the whole thing
@@nics-systems-electric thanks for responding. I'm not in the business, so I don't know the ins and outs of what's allowed, but I came across a box of "sprinkler spares" in a plant room I was clearing - there were heads, adapters, and a couple boxes of glass vials, with a temperature rating. I wonder if there just for accidental activations. They could also have been a throwback to years gone by, as the system had long since been fully drained... Love the videos regardless!!!
I’m surprised that there is no delay. Usually there is a dial to adjust the timing. I always had to have fire alarm activate within 90 seconds of a sprinkler head going off to meet NFPA. This delay in the alarm allows pressure fluctuations. I also don’t see a backflow preventer. This keeps the stagnant water from getting sucked back into the city water supply if there was a water main break. First time seeing this channel and very intrigued by why a residential house is set up like a commercial building with em light, fa panel, smokes, sprinklers, signage. Just curious as to why? Also the horn strobe combo on the outside is usually mounted above the FDC fire department connection so they know where to hook up the pumper. I bet the neighbors love it when you are testing the system. I honestly haven’t seen a house set up like this before.
I have forgotten what liquid is in the glass vials? alcohol / acetone? from my studies a few years back each color represents a certain burst temperature and each vial color has a different sized bubble in them for expansion, to make them go off at that temp
Nic you are super amazing with your videos. I love watching them. I was wondering have you considered the concealed sprinkler heads for your drop ceiling area?
i would say in the green hill/emerald hill community college career center services building will use the johnson controls water aqua-mist fog system series besides these traditional fire sprinklers. since it will reduce the flood and electrical water damage ish hazards. which would be a more efficient and safer alternative to reduce and minimize the risk.
I don't know how much I trust those they say they use less water but at the end of the day it's pretty simple the more water you get on the fire the better sprinklers are supposed to put out a lot of water the only place I would see them being acceptable is may be server rooms and similar
Actually, setting it off and shutting the valve RIGHT AWAY wouldn't be worse than say, dropping a water bottle on the floor, or accidentally splashing water while doing the dishes or cooking, see what I mean ? Basically everyday mishaps that don't usually end up with mold or even much damage at all except perhaps if electronics or unsealed wood get wet, it might leave some spots for the latter at most. ( *Read more* ) Sure, it would be annoying to mop the water, however it's not like a commercial system that will pump way more water every second and will keep flowing for hours until the arrival of the fire department and building manager or whoever has the rights to shut down the system.
It could have been deleted automatically or manually if it contained something like a link or a curse word, or even if you edited it too many times in a row. Happens to me quite often.
