i have found the info.. just sharing it now..
the following are used in the sprinklers:
1. an expanding liquid selected from the group consisting of toluene, a xylene, trichloroethylene, tetrachloroethylene and a mixture thereof.
2. lower monohydric aliphatic alcohol, a lower polyhydric aliphatic alcohol, a lower alkyl ester of a lower alkanecarboxylic acid, and a mixture thereof.
3. selected from the group consisting of toluene and a xylene.
4. selected from the group consisting of trichloroethylene and tetrachloroethylene.
5. modern sprinmlers are using ethyl acetate
