what are the controlling processes to distribute 100 fire extinguisher to 10 companies within a week?
In the event of a fire, I wouldn't bother with letting my 11 year old work out the learning process of pulling a fire alarm. I would just break the damn glass myself and pull the alarm myself because even if my son and I are out of harms way, other people may not be. There really isn't time in a fire to make it a learning experience.
Most places don't like it when you do that. It's like bringing your own ingredients to a restaurant. Maybe if you go to a small shop with a friendly mechanic it will be ok. Good luck.
I agree with kravis. Its like bringing your bacon and eggs to a restaurant to have them make you breakfast. They are able to give you a lower labor price since they are making money off the parts also. They will most likely not warranty the parts/job either since you supplied the parts. It doesn't hurt to ask though.
