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.

What element is used in overhead sprinklers?
If you are talking about the little rod that melts causing the sprinkler to spray water, it is not an element. It is either a metal alloy or plastic that melts at a relatively low temperature. The older sprinklers all used metal alloy, but as the usual alloy contained lead as one of the metals that alloy has been phased out due to concern over toxicity. Where metal alloy is still used it has been reformulated without lead. But the preference now is to use plastic rods.The image above shows a sprinkler with red colored plastic rod.
