Improve fire detection and reporting systems. Possibly improve in-home and in-business fire suppression systems, or even have them. I live in a fire prone area and none of the houses we looked at had fire suppression systems built-in, definitely something I'll be looking into if we have a chance to build.

But this is definitely an area where false positives are much less of a concern than false negatives. We'd rather have fire and rescue sent to non-incidents than not sent to real incidents.
