Fire Detection System

I want to build a system that detects an outdoor fire. I imagine such a system could use a heat sensor, infrared sensor or a combination of both. Once the fire is detected, it would trigger the opening of 12 volt water valves attached to my hose bibs, and then feed roof sprinklers.

I can find 12V water valves but no luck in finding an outdoor fire detection system (under a couple thousand dollars). Any ideas on how to build one?

If it were as easy as you dream then they probably would be inexpensive. When you think about the technicalities of automatically detecting a fire, at distance, outside and with reasonable reliability you soon realize that it's not so simple a task.
