The sprinkler system will only flow water during a fire if there is enough heat to cause a sprinkler head to open. The tempature at which that happens is determined by the actual head installed. Home systems use a fast reacting head.
As a residential system you have one of 2 options. If your house is 200sqr feet or less you can put the multipurpose system in which connects every head to a pluming fixture. The issue I have whith that is... It all needs to be rated pex and would need to be for a newly built house, and makes changing a fixture out double the trouble down the road. I love how plumping guys Bragg about being a sprinkler fitter when they have done one or 2 of these systems.
The other option is to have a stand alone system with its own pump, check valve and riser assembly with the stand alone water tanks and it get cpvc. These are mostly for state required housing or multi family homes.
