would be the water damage from a relatively easy to control fire, but
likely worth the risk. They should be zoned though, no point in
washing down the TV in the living room to control a little fire in the
kitchen. Easy to turn off would be another good feature, auto off
after flames subside for 10 minutes or so. even better, so long as it
had the ability to turn back on if the embers came back to life. Cost
would probably eliminate those desirable features though.

The sprinklers only go off in the area of the fire, not the entire property
so that is not a consideration. Homeowner should be able to turn them off,
also. In commercial/industrial applications, the shut off valve is usually
chained open to prevent accidental or mischievous turning off of the valve.
