72. Generally sprinkler systems work off of heat...
Not the alarm. Each head has a vial that blocks the water flow from the head. When it gets to a certain temp, there are different vials for different temps, the liquid expands enough to shatter the vial and starts the water.

There is such a thing as a deluge sprinkler system, but in general they are only installed in industrial areas like Foundries.
