Answer: No, not in your common household or
office building system. Each individual sprinkler head has a glass or metal
linkage that supports a plug in the sprinkler head. When the heat from the
fire reaches an appropriate temperature, the linkage will break away and
drop a plug which allows the water to spray onto the fire. Other heads in
the same area will not activate until the heat from the fire reaches the
appropriate temperature at those specific heads.
