C6 Corvette Drive Modes EXPLAINED and EXAMPLES
This car will do 0 to 60 in first gear
I have the cut out set up on my C6. I really don't use it so is there a simple way to lock it in the quiet mode? Can I ask one more question? Is it possible that the exhaust cut out could be causing a parasitic drain on my battery? ( I pulled the fuse on it, and it went to the loud mode.)
this is amazing. Good work!
Awesome! Thanks!
As a fire alarm collector, the keys are for as you said, to tell if it’s pulled or not. But it’s also a security and safety function. Your pull station has a toggle button. When pressed, it’s normal, when the button is pressed out, it’s activated. If the pull stations didn’t have a key, you can kinda foreshadow the outcome. Great video!
no video .
Insane what 505 hp in a lightweight car can do
That's such a cool halloween idea, those kids will remember that!
My c5 03 6 speed is the same speed
This just happened to me 😢😢 I'm literally upset that gm can't take responsibility
It is, so whoever pulled it cannot just reset it
Explosion-proof devices are generallly not waterproof, they simply have a very long physical path for any vapors or gasses to follow to reach a possible source of ignition. Probably not the best idea to use a pull station as a toy.
Not only is this designed so that any spark from the switch will not see off an explosive environment around it, there is a second layer to the design. The box is so sturdy that if the seals fail and the flammable/explosive vapor leaks into the box and gets set off, the box is sturdy enough to contain the explosion and prevent it from setting off the whole environment. That's the intrinsically safe part, even a single failure wont blow up your whole plant.
Pull stations are rated for 24 volts not 120 volt applications. Great video and nice station
These C6 Z06s are so badass.
could be for factories where explosions are possible
Great. Now I want a fire alarm pull station light switch.
SO I'm a Mechanical engineer and i work in failure analysis, and reliability. My guess without getting the all measurements I'm gonna guess a fatigue failure of the valve. Fatigue life is very fickle, but essentially the fatigue life is dependent on the number of cycles, and the amplitude of the cycles. Titanium unlike steel does not have an infinite fatigue life when the amplitude is kept within the elastic range of the material. I'm and guessing that you had a valve that had slightly OOS runout and that fatigue built up and finally let go on you. This failure mode will not be picked up by oil analysis. As for build suggestion I'm a fan of High RPM builds, area under the curve is a great trade off for peak HP. Especially when you consider that you can shift less often. You could be a full on MAD LAD and do a hybrid Renasis Rotary build with water meth induction and turbo. Lighten the rotors and balance the eccentric shaft for an 11-11.5K RPM motor that pulls 450hp, its gonna scream and be an absolute Blast to drive!
i just picked up an 06 and am new to the corvette world. ..... when changing modes, is there any difference in ride quality, exhaust note or steering input?
Not one comment about doing a 160mph pull in a vette listening to Olivia Rodrigo lol
The reason you need the key to reset pull stations is first of all not every control panel is addressable or kept up to date when the buildings are changed meaning not being able to reset the pull station without the key makes it easier to figure out which pull station was activated just by looking at it also it can help if your troubleshooting a nuisance or false alarm because you can easily see if it was someone pulling the pull station vs a fault in the wiring
Explosion proof means in electrical terms not that it will survive a blast but that if it's located in an area where you might have flammable/explosive vapors or dusts activating it will not create a spark that ignites the atmosphere, think things like chemical processing areas, fuel stations, refineries, explosive storage magazines at a quarry, grain silos etc
Would be amazing... But that hood is sooooo long. Spoiled by my MR2, fr-s, RX8 etc...
"Intrinsically safe" is the main keyword here. Anywhere you have a situation where there could be stuff in the air that's combustible (e g. Oil refinery, chemical plant, grain processing), the fire, building, HVAC, and electrical codes go bananas trying to prevent ANY chance of a spark causing an explosion. It's amazingly onerous to comply with as you've discovered with this relatively straightforward pull station (and for good reason given the risks to life and capital investment). Theres all sorts of intristincally safe devices and containers if you look around. Every company that works with industrial plants and automation a lot will have special models.
I would just ask a steel shop to cut the big muffle off, save the rips and add a pipe so the stock loock stay but the mufflers are no longer there
the main reason pull stations use a special tool or key is so people don't tamper with them. if pull stations didnt need anything to be reset, fall alarms would be much harder to track down because people would pull it and reset it quickly.
Did this guy really think it was something besides a sealed container to stop a spark from setting off an explosion?
There is a reason they have explosion proof, pool stations it’s because normal ones make a little ark, but if there was gas in the room that would start explosion, but the explosion proof ones don’t make a ark.
Interesting. Do you think it doesn’t make an arc based on the design of the switch mechanism, or do you think it is more to do with the construction of the case?
I think for the "keeping explosion in" part, Intrinsically safe pull stations are kinda for that in a sense. They prevent a spark that occurs when pulled, like how you can see a small spark when flipping a light switch, and that spark can.....ignite the gas in the building which is BAD. Fire alarm dude on YT has vid on Intrinsically safe vids
Very cool. I’ll check it out! What are your thoughts on the thickness of the walls? Do you think it is necessary?
@GridForgeMFG Its either just the design or for durability. I know you can also remove the backbox to just have the pull which is smaller.
"In my case I'm gonna run it off 28VDC..." Then what would you run it *ON* (besides the 120VAC)?
Why would it be run _off_ 28V to run on "wall power" if the 28V _IS_ one version of wall power when you have a system like that wired through the building? And if it's running _off_ the 28V or some other kind of wall power, then what would it be running ON?
Please excuse my ignorance in how these systems are usually installed. I was not (and still mostly now, am not) too familiar with them. For my application I just ran a power supply and used this switch to flow current to the bell and light when the switch was activated.
Man, the base box of that pull station looks like a special battery (although of course it's not one)!
My understanding is that these ruggedized pull stations are designed primarily to be electrically isolated in case there is a volatile airborne substance like fuel vapor or flour dust (yes, that is highly dangerous apparently). I believe it is supposed to be capable of withstanding a significant blunt force strike (and I suppose an explosion to some degree) without compromising the airtight seal. The fear is that sparks may ignite volatile airborne substances, especially while the pull station is operated because the contacts moving can cause a spark to occur. Also you are correct about the pull station normally being the size of the front part - on this design, the front part's normal electrical button is foregone and the button is built into the backbox instead. Normally this is attached through that big hole on the metal plate. The rugged assembly on the back is essentially a retrofit onto one of the existing conventional designs that happens to be rugged enough for such a use case.
If this is neat to you, check out explosion proof telephones as well.
Places like grain elevators or other places where flammable vapors exist. It keeps the guts separated in case of arcing in the switch.
They are used in the same environment that you need everything else explosionproof or atex
I love when I find a TH-cam video that answers a question I never knew I had
Fire code requires fire alarm pull stations to require a tool to reset as they are meant to be latching devices. Which could either be a hex key, screwdriver, or a key.
Just, pull station
Ah I see. Thanks for clarifying!
@GridForgeMFG and pipe feeding that can would be rigid
I have collected fire alarms for 6 years 7 if you count smoke alarms and I’ve never seen a pull station like that one
This comment makes me so happy haha. My $100 spend has been fully mentally vindicated by you.
WAIT WHAT IM PINNED AND YU REPLIED BEST TH-camR EVER
@@GridForgeMFG thank you!
@@GridForgeMFGalso very good first pull station!
@@GridForgeMFGthe max voltage for Almosr every fire alarm pull station or audible device same with visible fire alarms so like a horn strobe and pull station run on max 32 volts and all below and like 5 amps I think
The pull station is not huge it just has a back box I have not watch teh whole video yet sorry if u corrected it
It so if it is pulled in a room made for a explosion ie chemical storage it won’t blow up outside the room
3:03 Its so no one can tamper with it
Fire alarm systems are 24-27 volts dc and the only thing in fire alarm that takes 120 ac is the fire alarm control panel FACP and that is only to power the panel and the 120 is kept separate from the fire alarm wiring
Some systems are 12v dc
Explosion proof means intrinsically safe. They are meant for high risk settings, and theoretically cant be a source of ignition
These kinds of pull stations are also known as intrinsically safe pull stations. The reason it was so thick was because it was attached to a backbox. The actual pull station itself is just the part with the handle, terminals and switch and can be mounted to any backbox from somewhere like a hardware store as long as its the correct size. Also there are explosion proof pull stations made of plastic such as the ones made by simplex.
If you want more information about certain types of alarms, you really should talk to some people in the Fire Alarm Community. We aren't as bad as everyone makes us out to be.
@SFSWales that is what I tried to do. I at first had no idea about how fire alarm systems work, then attempted to ask around for further information within the Fire Alarm Community; about the inner workings of these systems. And nothing turned out good.
@ You need to find the right community, some of the enthusiasts around this hobby are right pricks.
@@ZacharyCesario o rly? I gotta know more. What is it about the fire alarm community that's coming off as a turn off? Gatekeepers?
13:53 if for example a cable is cut on a fire alarm pull station, or any fire alarm device, the fire alarm control panel, will not set off a full alarm. instead it will go into a trouble mode when only the control panel beeps and says that there is an open circuit
Just like your friend said, explosion proof pull stations aren't meant to be explosion proof, but instead, prevent explosions. Regular conventional pull stations, which this one is, run on 24 volts DC, and even though this isn't a lot of voltage, in hazardous conditions, you don't want a spark or anything igniting any flammable vapors, so that's what these pull stations are used for.
Some of these have a switch, that’s flips up or, the switch bridges the contacts on the NO or NC terminals, which is pretty much just a gate for electrical signals.
