ABSTRACT:
A thermally responsive frangible bulb containing a liquid which when heated expands to burst the bulb. In use the bulb may be positioned between a support and a sprinkler outlet cap such that when the bulb bursts the sprinkler outlet is opened. The bulb is at least partially filled with at least one halogen derivative of an aromatic hydrocarbon containing two or more halogen substituents such as 1,3-dichlorobenzene, or an aliphatic amide such a formamide. Use of these liquids enables a wide range of operating temperatures and a quick response operating time to be achieved.
