What are fire sprinkler heads made of?
Fire sprinkler heads feature heat-sensitive parts – either a glass bulb or a fusible link – that cause them to activate at a specific temperature. When a sprinkler head has a glass bulb, that bulb typically contains a glycerin-based liquid.
What is the red liquid in fire sprinklers?
The liquid within the ampule of the sprinkler head is a mixture of alcohol and water or glycerin and water. The % of each is changed to determine the activation temperature of the head. The color is from a dye and indicates the activation temperature.
Where does fire sprinkler water come from?
in most cases, sprinkler systems are supplied by the Water Main, where water comes into a home. the fire sprinkler system connects to the water main. in some systems the water flows through a Backflow Valve. A main water control valve is on the pipe that supplies the sprinkler system.

What does K factor mean in sprinklers?
discharge coefficient
How do you calculate K factor?
K factor is a ratio between the distance from the neutral bend line to the inside bend radius and the material thickness. K factor uses the formula K factor = δ/T.
How do I calculate sprinklers?
If you wish to calculate sprinkler layout manually, first determine the area of your yard by measuring its length and its width in feet. Then, multiply these numbers together. You may want to draw your yard to scale on a piece of graph paper. Each square should equal 1 square foot of lawn.
