An accidental sprinkler discharge is rare. Most sprinkler systems don’t activate through a detection process like a smoke alarm. Instead, they have a small glass filament inside it that melts and breaks when the temperature exceeds a certain (very high) threshold. In other words, the sprinkler only activates in a real fire — not just in a smoke condition.
They also operate when you bang into them and break the filament. This happens rarely in warehouse and manufacturing buildings and it only opens one sprinkler at a time.
But those buildings have high ceilings and it generally takes a forklift to trigger the sprinkler. The klutz potential in a home is much greater.
That sounds better.
