What is the liquid in a frangible - bulb fire sprinkler?
The glass bulb inside a fire sprinkler head is filled with a heat sensitive liquid (e.g., glycerine) that expands faster than the glass bulb as it gets hotter. Eventually, it expands so much that it causes the glass bulb to burst, releasing the water behind it.The different colors of liquid contained within the bulb correlate to the temperature at which the sprinkler head will activate:Orange - 135oFRed - 155oFYellow - 174oFGreen - 200oFBlue - 286oFPurple - 360oFBlack - 440OFDifferent colors are used in different environments depending on the average ambient heat in said environment. For instance, if you have a storage facility that needs to be kept at temperatures higher than 135 F, you can imagine why you wouldn't want a orange-bulbed fire sprinkler!

How does frangible ammunition damage an M16?

What has a low melting point and is useful in sprinklers?
modern automatic sprinklers use a glass bulb that is filled with a fluid that boils and expands at a preset temperature. the glass bulb has a small bubble in the fluid. when a fire causes the fluid to boil, it shatters the glass bulb, which is keeping the waterway seal of the sprinkler in place. When the seal is gone, water can flow through the sprinkler orfice, and extinguish the fire. older sprinkler models use a link and lever arrangement, with a link of solder that melts at a preset temperature. The link and levers of the sprinkler mechanically hold the waterway seal of the sprinkler closed. When the link melts, the mechanical seal is gone, and water can flow through the orfice.
