Searching for fire AND nozzle did not prove helpful.
Looking for recommended and or mandatory locations for fire suppression system nozzles. For a two-nozzle system, would trunk and passenger compartment, or passenger compartment and engine compartment be preferred? In a 3-nozzle system, would 2 nozzles go in the passenger compartment, or one in each of the car's 3 "boxes?"
In what location should the nozzle be placed? As high as possible on the ceiling? Firewall? Trunk ceiling or floor?

Thanks

 

I have a 2-nozzle. One is pointed at my nadz, the other at the fuel rail. If I had 3, the last one would be pointed at the fuel pump.

Sounds good to me. This is where mine will be located when the fire supression kit is installed.

BTW: What kit are you guys using?

 

why not one in the engine and one at the fuel pump? thats the two most likely places to ignite, isnt it?

If you have fire coming from your nads... well tell her to use some lube next time.

Have to protect the important stuff. The car came with the systmem installed that way. I also run a 4# hand bottle for grass fires, et al.

 

I would say that the idea is tou get yourself doused in AFFF or Halon to give yourself a few extra seconds to get the **** out of there. Regardless of where the fire is, I'd want a little bubble of non-fire around my *** while I pop the harness, wheel, window net, H&N and climb out of the car.

Besides, that seems to be the way most installs I've seen are setup. One on the pilot, one in the engine bay and one more at the fuel cell/fuel pump.

 

I was thinking the engine would be of least concern, as hopefully one would be conscious enough to cut the power and there would not be all that much fuel to burn up front. Plus the handheld fire bottle or rescue crew could take care of it. I guess though all the fuel is in the back, the front is more likely to ignite.
As for the pointing at the nads, I thought that was a joke, but that sounds like a good enough idea. Is it spraying up from your under your steering column, floor, seat, or down from the ceiling or rollbar or what?
I haven't picked a system yet but am looking at Racer Wholesale.com.

 

If it's mounted too high like on the top rollbar, the concentration of the Halon (etc) may not be enough to knock down the flames. It the cabin, under the dash pointed at the feet or crotch should be close enough.

In the engine bay, the most likely source would be fire from fuel (duh) or oil. I have seen nozzles on the fuel rail, over the back of the engine pointed at the rear of the block (centered over the exhaust) and near the fuel filter housing.

It should be positioned with the thought that it needs to provide you extra time to get out and away from the car as there is a risk that the fuel/oil may reignite on a hot surface after the extinguisher is empty.

Aim towards the driver or foot well but not at any one apendage. The system is under a good amount of pressure and Halon is cold as hell and coud cause freezer burn. This I know from just a small burst from a crew member on a victory lap. The gauge needle didn't even drop out of the green but my suit was frozen white around my knee.

 

I have a 2 nozzle system......one near my feet...the other in the top/center of the firewall (engineside) so it sprays 180 degrees outward

use AFFF.....

 

A 5# Halon system isn't enough for three outlets and you need to consider which reagent you are using. 1211 can be "sprayed," as it comes out as a liquid - it will go a couple of feet before it gasses off to do its work. 1301 comes out in something closer to a gaseous state (it was originally intended for closed-space systems, like in computer rooms. It blows away pretty easily.

I personally adhere to the "bubble of non-flame" theory, too. The best "nozzle" that I ever saw was a ring of aluminum tubing with small holes drilled in it, that ran around the top of the windscreen in an IMSA 962 Porsche. The idea was to rain a mist of gas down on the driver...

Edit - note that Halon is heavier than air so down in the footwell might not be the best answer...
