While I am genuinely impressed in how mechanically inclined you are, please tell me you’re not installing the entire fire suppression system. Judging off of the nozzles that you have I’m assuming it’s either a badger or kidde suppression system(side note that pipe needs to have plumbers tape around all of all the threads and you’re missing a duct and plenum nozzle ). But this system needs to be installed by a licensed fire suppression system technician, although I am curious what your work background is ? If you install it yourself there’s a 99% chance you will do something wrong and you will not get a passing tag, and it will end up costing you more money in the long run. If you have any questions feel free to reach out.
