Fire Suppression system installations Options

[BillJ]

Looking to update a race car with a 3-bay suppression system. I have done this many years ago but looking for suggestions on ideal routing for the lines and bottle location. Car has two seats (although rarely used right seat) so may impact routing and will probably do a dual nozzle in the cabin to make sure any riders are covered. Will want to spray both banks of carbs in the engine bay and one nozzle for the fuel cell space.

Anyone have some good pictures of routing they have done and where to locate bottle so it is out of the way? Pull locations appreciated too.

Thanks!

I don't think Halon is legal anymore with most sanctioning bodies. Certainly not with any around here.
Sounds like you've got the right thought - 2 nozzles @ engine, 1 @ fuel cell and 1@ driver. Not really any room against firewall to mount the bottle, especially if there's a passenger seat, so the bottle will have to be in passenger footwell. I've seen the pull handle positioned so emergency workers can reach from outside the car through a window.

I think Halon is still legal.
I just checked SVRA rules and they have no problem with it

the replacement gas (Halotron?) is 50% as effective and requires twice the size of bottle to equal the same number of seconds of protection

its still available for sale and for refill
I do believe that manufacture of New Halon gas has been discontinued except for military use.....

so the price went up... but its still available last time I checked.

the foam type, water based systems have advantages in that they are easily refillable. But they are messy and subject to freeze damage too.

all of the types of extinguishers have their advantages and disadvantages
