It is further assumed that phase change contributes negligibly to the liquid mass, and that the vapor is in equilibrium with the liquid and follows Clausius-Clapeyron behavior. Colours vary according to temperature settings, as detailed in the table below. Only fire sprinkler elements that reach their temperature breaking point activate. The colour codes seen above relate to the glass bulb colour. These sprinkler’s 5mm thermal bulb or fusible link must reach a certain temperature to break the element and release water. The frangible bulb sprinkler (fig. The bulb breaks as a result of the thermal expansion of the liquid inside the bulb. There is a common misconception of the fire sprinkler system that they trigger by smoke. Sprinklers must be installed after the piping is in place, to prevent mechanical damage. Sprinkler heads operate individually. In basic terms, this thermal sensitivity is how fast the liquid inside the glass bulb on sprinkler head will absorb the heat, expand, and then break open. A), a solder link (Fig. Quartzoid bulb sprinkler) The small bulb, usually of pyrex glass, contains a liquid which does not completely fill the bulb, leaving a small air bubble entrapped in it. It is to be installed in the protective district via ductwork, acting as a fire detector and auto sprayer.
