This quick action doesn't allow the fire to build up heat and toxic gases. Allowing you, the homeowner more time to escape. If one sprinkler head goes off, they all will. Again, not true. Automatic sprinklers spray water only the immediate area of the fire thus avoiding widespread water damage.
Sprinklers go off accidentally.
Accidental water damage caused by these systems is rare. One study concluded that sprinkler accidents are generally less likely and less severe than mishaps involving standard home plumbing. Sprinklers are ugly. We say they don't have to be that way. Pipes can be hidden in ceilings and walls.
