If one sprinkler goes off, don't they all go off?
No. Only the sprinkler over the fire will activate. When the heat of a fire raises the sprinkler to its operating temperature, usually between 135°F to 175° F, the fusible link or frangible glass bulb will break, dislodging a plug and opening the orifice so that water can spray out.
