How Sprinklers Work
Sprinklers detect a fire in the early stages of development and will operate before
the fire develops and becomes life-threatening. The system is heat-activated at
a temperate of 57 degrees Celsius (domestic property) when the concealed lid drops
off. At 65 - 70 degrees Celsius, the glass bulb of the sprinkler head smashes, allowing
the plug to drop and water to be released. Water from the activated sprinkler will
cool the atmosphere around the fire, which will reduce the rate of burning, the
production of smoke and will protect the surrounding materials limiting fire spread.
Research illustrates that the vast majority of fires controlled by a sprinkler system
have involved just one sprinkler head activating.
