Abstract
An adapter is mountable to a trigger mechanism of a conventional fire extinguisher to form a portable automatic fire extinguisher. The adapter comprises a compressed spring held in place with a heat release fusible link. If fire occurs in the vicinity of the adapter, the fusible link separates allowing the compression spring to depress the fire extinguisher trigger mechanism.
