A sprinkler system is a fire fighting device that is installed in buildings as a preventative measure. The sprinkler heads are placed in the ceilings facing toward either the floor or towards any fire hit spots. The other end of the sprinkler system is connected to a number of pipes and a high pressure water supply. Fire sprinkler systems work by way of a heat sensor bulb that is contained in the head of the system. If a fire starts, the heat from the flames will rise to heat the sprinkler sensor. When the heat exceeds a set point, the sensor bulb will break and the water will spray out onto the fire. A sprinkler system is an automatic system.
