How does it work?

Step 1: The sprinkler heads detect heat

The sprinkler contains glycerin-based liquid contained in a bulb which expands
when it comes contact with air heated. In the JKR tower, it uses the red bulb

which expands and shatters the bulb at 68˚C which activates the sprinkler head.

Step 2: Fire sprinklers put out the fire

Each sprinkler head in JKR Tower is attached to a pipe that connects to the water
tank located at level 18 of the building. When it activates, a valves opens allowing
pressurized water from pipe system to flow out. It is crucial the system to be
pressurized. This allows water to spray outward in an arc to put out the fire and
prevent from reigniting.

Step 3: Fire sprinklers minimize the water damage

The sprinkler heads function individually since it takes only one or two sprinklers
to put out fire. This allows water damage to be confined in small area. Compared
to fire hose, the fire sprinkler system uses six times less water to put out fire
which lessen the water damage to the JKR tower than a visit from the fire
department.
