Automatic fire sprinklers are designed to extinguish fires simultaneously on different floors.

Automatic fire sprinklers are designed to extinguish fires simultaneously on different floors.

• A. True
• B. False
• C. Only on tall buildings
• D. Depends on water supply

Answer: (B)

Sprinkler systems respond to heat at the local head, not to a building-wide signal. Each sprinkler head is activated by reaching a specific temperature, so only the heads in the area of the fire will release water. The rest of the heads stay closed until they’re heated as well. That means fires on different floors won’t all flood at once; the system is designed to control and suppress the fire where it starts, minimizing water damage to unaffected areas. There are specialized system types where water is released more broadly (like deluge or certain pre-action setups), but in a standard automatic wet-pipe arrangement, activation is localized to the affected area.
