$, lobbyists, and politicians

[Clip-Clop]

Kind of a reasonable idea in tightly packed fire rich areas.

That said, they only work for fires that are started inside the home, while most areas that could possibly benefit from the tech the fires are started outside the home.

Also the catastrophic failure and costs associated with just one sprinkler head failing in one home when no one is inside the house is remarkable.

This happened to one of my clients (forward thinking and installed even though he wasn't required to) and the lower level of the home was completely flooded and the cost to repair was around 300K. Fine for me since it destroyed my system and I got to replace it but a disaster otherwise.
