Essentially it boils down to what the current fire marshals laws are.
The current laws do not require such a system to be in place, and as such, companies do not fork out cash to purchase such a system.
One would think it is common sense to make your bulding as safe as possible, but I've even seen buildings engineered with only the minimum dollar in
mind, leading to a shortened and rather dangerous lifespan of its frame, foundation, power grid, and yes, even the sprinkler system.
