Only the Sprinkler Closest to the Fire
Will Activate, Spraying Water Directly
on the Fire

Fire sprinklers are individually heat-activated and connected to a network of copper or steel pipe with water under pressure. When the heat of a fire raises the sprinkler to its operating temperature, usually between 135°-175°F, a fusible link or glass bulb will activate only that sprinkler over the fire, thereby releasing water only over the source of heat.

How They Work

Watch a short animated movie that explains the workings of home fire sprinklers.

How Much Water?

Fire sprinklers use far less water than fire hoses. Watch a short animated movie that demonstrates just how little.
